Although their ecological and cultural significance is high, wood-pastures are rapidly deteriorating all over Europe, mainly due to changing land use. We still lack a basic understanding of the ecological value of wood-pastures, and in which features they differ from other landscape elements. In this paper we investigated the ecological value of wood-pastures for passerine birds by (i) comparing bird assemblages of wood-pastures with those of closed forests and open pastures and (ii) exploring the relationships between variables describing wood-pastures and species traits of the bird assemblages. Our study region (Southern Transylvania, Romania) provides a unique opportunity to understand the importance of a traditional cultural and ecological environment for many different organisms. Wood-pastures had a higher overall number of bird species, and a higher spatial turnover in bird community composition than closed forests and open pastures. We found significant associations between bird species traits and habitat structural elements in wood-pastures such as large trees, oak- and pear trees and shrubs. Our findings suggest that traditional wood-pastures in Southern Transylvania have distinct and rich passerine bird communities. This richness is inextricably linked to the multifunctional, low-intensity land use traditionally applied in the wood-pastures that promotes high niche diversity. For effective conservation of the biodiversity of wood-pastures, a detailed understanding is needed of how different management regimes may influence the key structural elements of wood-pastures relevant for biodiversity and these should be protected. Waldweiden sind empfindliche Ökosysteme, weil sie durch multifunktionale Bewirtschaftung geringer Intensität entstehen und davon abhängen. Auch wenn ihre ökologische und kulturelle Bedeutung hoch ist, verschlechtert sich der Zustand der Waldweiden in ganz Europa mit hoher Geschwindigkeit, überwiegend aufgrund von geänderter Landnutzung. Uns fehlt immer noch ein grundlegendes Verständnis des ökologischen Wertes der Waldweiden und der Eigenschaften, durch die sie sich von anderen Landschaftselementen unterscheiden. In dieser Studie untersuchten wir den ökologischen Wert von Waldweiden für Singvögel indem wir (1) die Vogelgemeinschaften von Waldweiden mit denen geschlossener Wälder und offener Weiden verglichen und (2) die Beziehungen zwischen die Waldweiden beschreibenden Variablen und Artmerkmalen der Vogelgemeinschaften erkundeten. Unser Untersuchungsgebiet (Südliches Transsilvanien, Rumänien) bietet eine einzigartige Gelegenheit, die Bedeutung einer traditionellen kulturellen und ökologischen Umwelt für viele verschiedene Organismen zu verstehen. Die Waldweiden wiesen eine höhere Gesamtzahl von Vogelarten auf und zeigten einen höheren räumlichen Turnover in der Zusammensetzung der Vogelgemeinschaften als geschlossener Wald und offene Weide. Wir fanden signifikante Beziehungen zwischen den Artmerkmalen der Vögel und Strukturelementen der Waldweiden wie alte Bäume, Eichen- und Birnbäume sowie Sträucher. Unsere Befunde legen nahe, dass die traditionellen Waldweiden im südlichen Transsilvanien charakteristische und artenreiche Vogelgemeinschaften beherbergen. Dieser Artenreichtum ist untrennbar mit der wenig intensiven, multifunktionalen Landnutzung verbunden, die traditionell in den Waldweiden ausgeübt wird und eine hohe Nischendiversität fördert. Für einen effektiven Schutz der Biodiversität der Waldweiden benötigen wir ein detailliertes Verständnis des Einflusses unterschiedlicher Managementmaßnahmen auf die entscheidenden Strukturelemente von Waldweiden mit Relevanz für die Biodiversität. Diese Strukturelemente sollten geschützt werden.</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Zotti, M</style></author><author><style face="normal" font="default" size="100%">Ambrosio, E</style></author><author><style face="normal" font="default" size="100%">Di Piazza, S</style></author><author><style face="normal" font="default" size="100%">Bidaud, A</style></author><author><style face="normal" font="default" size="100%">Boccardo, F</style></author><author><style face="normal" font="default" size="100%">Pavarino, M</style></author><author><style face="normal" font="default" size="100%">Mariotti, M G</style></author><author><style face="normal" font="default" size="100%">Vizzini, A</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Ecology and diversity of Cortinarius species (Agaricales, Basidiomycota) associated with Quercus ilex L. in the Mediterranean area of Liguria (North-western Italy)</style></title><secondary-title><style face="normal" font="default" size="100%">Plant Biosystems - An International Journal Dealing with all Aspects of Plant Biology</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Agaricomycetes</style></keyword><keyword><style  face="normal" font="default" size="100%">Biodiversity</style></keyword><keyword><style  face="normal" font="default" size="100%">conservation</style></keyword><keyword><style  face="normal" font="default" size="100%">Cortinariaceae</style></keyword><keyword><style  face="normal" font="default" size="100%">holm-oak</style></keyword><keyword><style  face="normal" font="default" size="100%">Macrofungi</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2014</style></year></dates><publisher><style face="normal" font="default" size="100%">Taylor &amp; Francis</style></publisher><pages><style face="normal" font="default" size="100%">1-10</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Cortinarius is one of the most widespread macrofungal genera.

Securing the delivery of services in such multi-ownership landscapes is challenging, because it is difficult to assure tight compliance to spatially explicit management rules at the level of individual properties, which may hinder the conservation of critical landscape features. To deal with these constraints, a multi-objective simulation-optimization procedure was developed to select non-spatial management regimes that best meet landscape-level objectives, while accounting for uncoordinated and uncertain response of individual landowners to management rules. Optimization approximates the non-dominated Pareto frontier, combining a multi-objective genetic algorithm and a simulator that forecasts trends in landscape pattern as a function of management rules implemented annually by individual landowners. The procedure was demonstrated with a case study for the optimum scheduling of fuel treatments in cork oak forest landscapes, involving six objectives related to reducing management costs (1), reducing fire risk (3), and protecting biodiversity associated with mid-and late-successional understories (2). There was a trade-off between cost, fire risk and biodiversity objectives, that could be minimized by selecting management regimes involving ca. 60% of landowners clearing the understory at short intervals (around 5 years), and the remaining managing at long intervals (ca. 75 years) or not managing. The optimal management regimes produces a mosaic landscape dominated by stands with herbaceous and low shrub understories, but also with a satisfactory representation of old understories, that was favorable in terms of both fire risk and biodiversity. The simulation-optimization procedure presented can be extended to incorporate a wide range of landscape dynamic processes, management rules and quantifiable objectives. It may thus be adapted to other socio-ecological systems, particularly where specific patterns of landscape heterogeneity are to be maintained despite imperfect management by multiple landowners.</style></abstract><notes><style face="normal" font="default" size="100%">APS</style></notes><research-notes><style face="normal" font="default" size="100%">APS</style></research-notes></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Pinho, P</style></author><author><style face="normal" font="default" size="100%">Llop, E</style></author><author><style face="normal" font="default" size="100%">Ribeiro, M C</style></author><author><style face="normal" font="default" size="100%">Cruz, C</style></author><author><style face="normal" font="default" size="100%">Soares, A</style></author><author><style face="normal" font="default" size="100%">Pereira, M J</style></author><author><style face="normal" font="default" size="100%">Branquinho, C</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Tools for determining critical levels of atmospheric ammonia under the influence of multiple disturbances</style></title><secondary-title><style face="normal" font="default" size="100%">Environmental Pollution</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Air Pollutants</style></keyword><keyword><style  face="normal" font="default" size="100%">Air Pollutants: analysis</style></keyword><keyword><style  face="normal" font="default" size="100%">ammonia</style></keyword><keyword><style  face="normal" font="default" size="100%">Ammonia: analysis</style></keyword><keyword><style  face="normal" font="default" size="100%">Atmosphere</style></keyword><keyword><style  face="normal" font="default" size="100%">Atmosphere: chemistry</style></keyword><keyword><style  face="normal" font="default" size="100%">Biodiversity</style></keyword><keyword><style  face="normal" font="default" size="100%">Critical thresholds</style></keyword><keyword><style  face="normal" font="default" size="100%">Environmental Monitoring</style></keyword><keyword><style  face="normal" font="default" size="100%">Environmental Monitoring: methods</style></keyword><keyword><style  face="normal" font="default" size="100%">Eutrophication</style></keyword><keyword><style  face="normal" font="default" size="100%">Functional groups</style></keyword><keyword><style  face="normal" font="default" size="100%">Global change</style></keyword><keyword><style  face="normal" font="default" size="100%">lichens</style></keyword><keyword><style  face="normal" font="default" size="100%">Lichens: chemistry</style></keyword><keyword><style  face="normal" font="default" size="100%">Lichens: classification</style></keyword><keyword><style  face="normal" font="default" size="100%">nitrogen</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2014</style></year></dates><publisher><style face="normal" font="default" size="100%">Elsevier Ltd</style></publisher><volume><style face="normal" font="default" size="100%">188</style></volume><pages><style face="normal" font="default" size="100%">88-93</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Critical levels (CLEs) of atmospheric ammonia based on biodiversity changes have been mostly calculated using small-scale single-source approaches, to avoid interference by other factors, which also influence biodiversity. Thus, it is questionable whether these CLEs are valid at larger spatial scales, in a multi- disturbances context. To test so, we sampled lichen diversity and ammonia at 80 sites across a region with a complex land-cover including industrial and urban areas. At a regional scale, confounding factors such as industrial pollutants prevailed, masking the CLEs. We propose and use a new tool to calculate CLEs by stratifying ammonia concentrations into classes, and focusing on the highest diversity values. Based on the significant correlations between ammonia and biodiversity, we found the CLE of ammonia for Mediterranean evergreen woodlands to be 0.69 mgm?3, below the previously accepted value of 1.9 mgm?3, and below the currently accepted pan-European CLE of 1.0 mgm?3</style></abstract><accession-num><style face="normal" font="default" size="100%">24568792</style></accession-num></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Martín-Queller, Emi</style></author><author><style face="normal" font="default" size="100%">Diez, Jeffrey M</style></author><author><style face="normal" font="default" size="100%">Ibáñez, Inés</style></author><author><style face="normal" font="default" size="100%">Saura, Santiago</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Effects of silviculture on native tree species richness: interactions between management, landscape context and regional climate</style></title><secondary-title><style face="normal" font="default" size="100%">Journal of Applied Ecology</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Biodiversity</style></keyword><keyword><style  face="normal" font="default" size="100%">Disturbance ecology</style></keyword><keyword><style  face="normal" font="default" size="100%">hierarchical Bayes</style></keyword><keyword><style  face="normal" font="default" size="100%">intermediate disturbance hypothesis</style></keyword><keyword><style  face="normal" font="default" size="100%">landscape ecology</style></keyword><keyword><style  face="normal" font="default" size="100%">Mediterranean forests</style></keyword><keyword><style  face="normal" font="default" size="100%">metacommunity dynamics</style></keyword><keyword><style  face="normal" font="default" size="100%">partial harvesting</style></keyword><keyword><style  face="normal" font="default" size="100%">spatial scale</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2013</style></year></dates><volume><style face="normal" font="default" size="100%">50</style></volume><pages><style face="normal" font="default" size="100%">775-785</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">* Patterns of forest biodiversity are shaped by a complex set of processes operating over different spatial scales. Climate may largely determine species richness at regional scales, but biotic interactions and disturbance events are known to be important at local scales. The interactions between these local and regional processes are poorly understood, complicating efforts to manage for biodiversity. * In this study, we used Spanish forest inventory data, together with hierarchical Bayesian models, to analyse how different harvest intensities affect patterns of species richness in a 152 000 km2 area in central Spain. Particularly, we quantified the interacting effects of locally applied silvicultural disturbances, of those applied in the surrounding landscape, and of the regional climate on native tree species richness. * Our study supports the overall hypothesis that a hierarchical set of processes influence species richness, with regional climate contributing to shape the impacts of local harvesting practices and other environmental variables (topography and productivity). * In particular, we found that partial harvesting in both coniferous and broad-leaved Mediterranean forests may support greater tree species richness than complete harvesting and no management. However, this effect depended on the ecosystem and the surrounding landscape, being much less likely in semi-arid regions under water stress conditions and in landscapes dominated by managed forests (and particularly by completely harvested stands). * In general, forest stands exhibited increased tree species richness when surrounded by species-rich riparian forests, probably due to metacommunity dynamics and/or ecological history (land uses) of the area. * Synthesis and applications. The effects of forest management on local species richness were shaped by coarse climate conditions and by the type and extent of other management practices in the surrounding landscapes. Therefore, to develop effective forestry management plans that optimize local diversity, we need to (i) apply regionally tailored practices with lower harvest intensities in areas of greater hydric stress; (ii) avoid the extensive application of a single silvicultural system over large areas and (iii) preserve a mosaic of species-rich forests that can act as sources of colonizers to enrich the regenerating stands nearby.</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Otero, Iago</style></author><author><style face="normal" font="default" size="100%">Boada, Martí</style></author><author><style face="normal" font="default" size="100%">Tàbara, Joan David</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Social–ecological heritage and the conservation of Mediterranean landscapes under global change.

This has led some conservationists and social scientists to highlight the need for enhanced knowledge on the complex interrelationships between cultural and biological diversities if successful conservation strategies are to be achieved. In this work we show how the long-term coevolution between peasants and their environment sustained habitats and species that are now declining along with rural exodus in a mountainous area of the Mediterranean, a region where the maintenance of diverse landscapes is very much related to the presence of traditional rural activities. We provide an account of agrosilvopastoral practices once performed by the local peasant community and show their embeddedness in a particular set of institutions and worldview within an adaptive social–ecological system. We argue that such practices constitute an essential social–ecological heritage entailing valuable insights for the conservation of Mediterranean landscapes under conditions of global change.</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Nerlich, K</style></author><author><style face="normal" font="default" size="100%">Graeff-Hönninger, S</style></author><author><style face="normal" font="default" size="100%">Claupein, W</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Agroforestry in Europe: a review of the disappearance of traditional systems and development of modern agroforestry practices, with emphasis on experiences in Germany</style></title><secondary-title><style face="normal" font="default" size="100%">Agroforestry Systems</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Biodiversity</style></keyword><keyword><style  face="normal" font="default" size="100%">high-quality timber</style></keyword><keyword><style  face="normal" font="default" size="100%">management</style></keyword><keyword><style  face="normal" font="default" size="100%">modern agroforestry</style></keyword><keyword><style  face="normal" font="default" size="100%">short rotation coppice</style></keyword><keyword><style  face="normal" font="default" size="100%">traditional agroforestry</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2012</style></year></dates><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Agroforestry is a new name for a rather old practice. From a historical point of view, various agroforestry systems existed in Europe, of which the wood pastures (Neolithicum), the Dehesas in Spain (*4,500 years old) and the Hauberg of the Siegerland (established in the Middle Age) are the most prominent. Other widespread systems in Europe were hedgerows, windbreaks and Streuobst (orchard intercropping). Due to mechanisation and intensiﬁcation of agriculture, trees have been progressively removed from agricultural ﬁelds and traditional agroforestry systems slowly disappeared. Today, agroforestry systems are again increasing in interest as they offer the potential to solve important ecological and, especially, biodiversity problems, while at the same time enabling the production of food, wood products and fodder for cattle. Although agroforestry systems offer many advantages, many farmers are sceptical of these systems and are critical and risk-averse with regard to adopting new practices. However, in comparison to traditional systems, modern agroforestry systems can be adapted to current farming practices. By selecting suitable trees and appropriate tree management, highquality timber can be produced without inﬂuencing agricultural crops excessively. In future, agroforestry systems will become increasingly important as they offer the prospect of producing woody perennials for bioenergy on the same land area as food and/or fodder plants, while enhancing overall biodiversity.</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Borghetti, M.</style></author><author><style face="normal" font="default" size="100%">La Mantia, T.</style></author><author><style face="normal" font="default" size="100%">Menozzi, P.</style></author><author><style face="normal" font="default" size="100%">Piotti, a</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">The likely impact of climate change on the biodiversity of Italian forests</style></title><secondary-title><style face="normal" font="default" size="100%">Forest@ - Rivista di Selvicoltura ed Ecologia Forestale</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">2012</style></keyword><keyword><style  face="normal" font="default" size="100%">245-250</style></keyword><keyword><style  face="normal" font="default" size="100%">9</style></keyword><keyword><style  face="normal" font="default" size="100%">Adaptation</style></keyword><keyword><style  face="normal" font="default" size="100%">biodiversità delle foreste italiane</style></keyword><keyword><style  face="normal" font="default" size="100%">Biodiversity</style></keyword><keyword><style  face="normal" font="default" size="100%">borghetti m</style></keyword><keyword><style  face="normal" font="default" size="100%">citation</style></keyword><keyword><style  face="normal" font="default" size="100%">climate change</style></keyword><keyword><style  face="normal" font="default" size="100%">climatico sulla</style></keyword><keyword><style  face="normal" font="default" size="100%">contents</style></keyword><keyword><style  face="normal" font="default" size="100%">FOREST</style></keyword><keyword><style  face="normal" font="default" size="100%">http</style></keyword><keyword><style  face="normal" font="default" size="100%">impact</style></keyword><keyword><style  face="normal" font="default" size="100%">it</style></keyword><keyword><style  face="normal" font="default" size="100%">Italy</style></keyword><keyword><style  face="normal" font="default" size="100%">la mantia t</style></keyword><keyword><style  face="normal" font="default" size="100%">menozzi p</style></keyword><keyword><style  face="normal" font="default" size="100%">online 2012-11-19</style></keyword><keyword><style  face="normal" font="default" size="100%">piotti a</style></keyword><keyword><style  face="normal" font="default" size="100%">probabili impatti del cambiamento</style></keyword><keyword><style  face="normal" font="default" size="100%">sisef</style></keyword><keyword><style  face="normal" font="default" size="100%">url</style></keyword><keyword><style  face="normal" font="default" size="100%">www</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2012</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2012///</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://www.sisef.it/forest@/?doi=10.3832/efor0708-009</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">9</style></volume><pages><style face="normal" font="default" size="100%">245 - 250</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><issue><style face="normal" font="default" size="100%">6</style></issue></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Penuelas, J</style></author><author><style face="normal" font="default" size="100%">Rico, L</style></author><author><style face="normal" font="default" size="100%">Ogaya, R</style></author><author><style face="normal" font="default" size="100%">Jump, A S</style></author><author><style face="normal" font="default" size="100%">Terradas, J</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Summer season and long-term drought increase the richness of bacteria and fungi in the foliar phyllosphere of Quercus ilex in a mixed Mediterranean forest</style></title><secondary-title><style face="normal" font="default" size="100%">Plant Biology</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Bacteria</style></keyword><keyword><style  face="normal" font="default" size="100%">Bacteria: genetics</style></keyword><keyword><style  face="normal" font="default" size="100%">Bacteria: growth &amp;

Bacteria and fungi were assessed during ontogenic development of the leaves, from the wet spring to the dry summer season in control plots and in plots subjected to drought conditions mimicking those projected for future decades. Our aim was to monitor succession in microbiota during the colonisation of plant leaves and its response to climate change. Ontogeny and seasonality exerted a strong influence on richness and diversity of the microbial phyllosphere community, which decreased in summer in the whole leaf and increased in summer in the epiphytic phyllosphere. Drought precluded the decrease in whole leaf phyllosphere diversity and increased the rise in the epiphytic phyllosphere. Both whole leaf bacterial and fungal richness decreased with the decrease in physiological activity and productivity of the summer season in control trees. As expected, the richness of epiphytic bacteria and fungi increased in summer after increasing time of colonisation. Under summer dry conditions, there was a positive relationship between TRF (terminal restriction fragments) richness and drought, both for whole leaf and epiphytic phyllosphere, and especially for fungal communities. These results demonstrate that changes in climate are likely to significantly alter microbial abundance and composition of the phyllosphere. Given the diverse functions and large number of phyllospheric microbes, the potential functional implications of such community shifts warrant exploration.</style></abstract><accession-num><style face="normal" font="default" size="100%">22289059</style></accession-num></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Barreto, Maria C</style></author><author><style face="normal" font="default" size="100%">Houbraken, Jos</style></author><author><style face="normal" font="default" size="100%">Samson, Robert A</style></author><author><style face="normal" font="default" size="100%">Brito, Dulce</style></author><author><style face="normal" font="default" size="100%">Gadanho, Mário</style></author><author><style face="normal" font="default" size="100%">San Romão, Maria V</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Unveiling the fungal mycobiota present throughout the cork stopper manufacturing process</style></title><secondary-title><style face="normal" font="default" size="100%">FEMS Microbiology Ecology</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Biodiversity</style></keyword><keyword><style  face="normal" font="default" size="100%">cloning</style></keyword><keyword><style  face="normal" font="default" size="100%">Cork</style></keyword><keyword><style  face="normal" font="default" size="100%">denaturing gel electrophoresis</style></keyword><keyword><style  face="normal" font="default" size="100%">Denaturing Gradient Gel Electrophoresis</style></keyword><keyword><style  face="normal" font="default" size="100%">DNA</style></keyword><keyword><style  face="normal" font="default" size="100%">Fungal</style></keyword><keyword><style  face="normal" font="default" size="100%">Fungal: genetics</style></keyword><keyword><style  face="normal" font="default" size="100%">fungi</style></keyword><keyword><style  face="normal" font="default" size="100%">Fungi: classification</style></keyword><keyword><style  face="normal" font="default" size="100%">Fungi: isolation &amp; purification</style></keyword><keyword><style  face="normal" font="default" size="100%">humidity</style></keyword><keyword><style  face="normal" font="default" size="100%">Industry</style></keyword><keyword><style  face="normal" font="default" size="100%">Metagenome</style></keyword><keyword><style  face="normal" font="default" size="100%">mycobiota diversity</style></keyword><keyword><style  face="normal" font="default" size="100%">Penicillium</style></keyword><keyword><style  face="normal" font="default" size="100%">Penicillium: classification</style></keyword><keyword><style  face="normal" font="default" size="100%">Penicillium: isolation &amp; purification</style></keyword><keyword><style  face="normal" font="default" size="100%">phylogeny</style></keyword><keyword><style  face="normal" font="default" size="100%">Plant Bark</style></keyword><keyword><style  face="normal" font="default" size="100%">Plant Bark: microbiology</style></keyword><keyword><style  face="normal" font="default" size="100%">Portugal</style></keyword><keyword><style  face="normal" font="default" size="100%">Quercus</style></keyword><keyword><style  face="normal" font="default" size="100%">Quercus: microbiology</style></keyword><keyword><style  face="normal" font="default" size="100%">Ribosomal Spacer</style></keyword><keyword><style  face="normal" font="default" size="100%">Ribosomal Spacer: genetics</style></keyword><keyword><style  face="normal" font="default" size="100%">Spain</style></keyword><keyword><style  face="normal" font="default" size="100%">Temperature</style></keyword><keyword><style  face="normal" font="default" size="100%">uncultivable fungal species</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2012</style></year></dates><volume><style face="normal" font="default" size="100%">82</style></volume><pages><style face="normal" font="default" size="100%">202-214</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">A particular fungal population is present in the main stages of the manufacturing process of cork discs. Its diversity was studied using both dependent (isolation) and independent culture methods (denaturing gel gradient electrophoresis and cloning of the ITS1-5.8S-ITS2 region). The mycobiota in the samples taken in the stages before and after the first boiling seems to be distinct from the population in the subsequent manufacturing stages. Most isolated fungi belong to the genera Penicillium, Eurotium and Cladosporium. The presence of uncultivable fungi, Ascomycota and endophytes in raw cork was confirmed by sequencing. The samples taken after the first boiling contained uncultivable fungi, but in a few samples some isolated fungi were also detected. The main taxa present in the following stages were Chrysonilia sitophila, Penicillium glabrum and Penicillium spp. All applied techniques had complementary outcomes. The main factors driving the shift in cork fungal colonization seem to be the high levels of humidity and temperature to which the slabs are subjected during the boiling process.</style></abstract><accession-num><style face="normal" font="default" size="100%">22630140</style></accession-num></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Simonson, William D</style></author><author><style face="normal" font="default" size="100%">Allen, Harriet D</style></author><author><style face="normal" font="default" size="100%">Coomes, David A</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Use of an airborne lidar system to model plant species composition and diversity of Mediterranean oak forests.</style></title><secondary-title><style face="normal" font="default" size="100%">Conservation biology : the journal of the Society for Conservation Biology</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Biodiversity</style></keyword><keyword><style  face="normal" font="default" size="100%">Biological</style></keyword><keyword><style  face="normal" font="default" size="100%">cluster analysis</style></keyword><keyword><style  face="normal" font="default" size="100%">Conservation of Natural Resources</style></keyword><keyword><style  face="normal" font="default" size="100%">Conservation of Natural Resources: methods</style></keyword><keyword><style  face="normal" font="default" size="100%">Ecosystem</style></keyword><keyword><style  face="normal" font="default" size="100%">mediterranean oak forest</style></keyword><keyword><style  face="normal" font="default" size="100%">Models</style></keyword><keyword><style  face="normal" font="default" size="100%">Portugal</style></keyword><keyword><style  face="normal" font="default" size="100%">predictive modeling</style></keyword><keyword><style  face="normal" font="default" size="100%">Quercus</style></keyword><keyword><style  face="normal" font="default" size="100%">Remote sensing</style></keyword><keyword><style  face="normal" font="default" size="100%">Remote Sensing Technology</style></keyword><keyword><style  face="normal" font="default" size="100%">Remote Sensing Technology: methods</style></keyword><keyword><style  face="normal" font="default" size="100%">Species Specificity</style></keyword><keyword><style  face="normal" font="default" size="100%">vascular plants</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2012</style></year></dates><volume><style face="normal" font="default" size="100%">26</style></volume><pages><style face="normal" font="default" size="100%">840-850</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Airborne lidar is a remote-sensing tool of increasing importance in ecological and conservation research due to its ability to characterize three-dimensional vegetation structure. If different aspects of plant species diversity and composition can be related to vegetation structure, landscape-level assessments of plant communities may be possible. We examined this possibility for Mediterranean oak forests in southern Portugal, which are rich in biological diversity but also threatened. We compared data from a discrete, first-and-last return lidar data set collected for 31 plots of cork oak (Quercus suber) and Algerian oak (Quercus canariensis) forest with field data to test whether lidar can be used to predict the vertical structure of vegetation, diversity of plant species, and community type. Lidar- and field-measured structural data were significantly correlated (up to r= 0.85). Diversity of forest species was significantly associated with lidar-measured vegetation height (R(2) = 0.50, p &lt; 0.001). Clustering and ordination of the species data pointed to the presence of 2 main forest classes that could be discriminated with an accuracy of 89% on the basis of lidar data. Lidar can be applied widely for mapping of habitat and assessments of habitat condition (e.g., in support of the European Species and Habitats Directive [92/43/EEC]). However, particular attention needs to be paid to issues of survey design: density of lidar points and geospatial accuracy of ground-truthing and its timing relative to acquisition of lidar data.</style></abstract><accession-num><style face="normal" font="default" size="100%">22731687</style></accession-num></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Mendes, Sara Margarida</style></author><author><style face="normal" font="default" size="100%">Santos, Joaquim</style></author><author><style face="normal" font="default" size="100%">Freitas, Helena</style></author><author><style face="normal" font="default" size="100%">Sousa, José Paulo</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Assessing the impact of understory vegetation cut on soil epigeic macrofauna from a cork-oak Montado in South Portugal</style></title><secondary-title><style face="normal" font="default" size="100%">Agroforestry Systems</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Biodiversity</style></keyword><keyword><style  face="normal" font="default" size="100%">cork-oak forests</style></keyword><keyword><style  face="normal" font="default" size="100%">soil macrofauna</style></keyword><keyword><style  face="normal" font="default" size="100%">sustainable management</style></keyword><keyword><style  face="normal" font="default" size="100%">understory management</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2011</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2011///</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://www.springerlink.com/index/10.1007/s10457-010-9358-z</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">82</style></volume><pages><style face="normal" font="default" size="100%">139 - 148</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Cork oak ‘‘Montados’’ are a particular Mediterranean ecosystem, which can be found in Southern Portugal. Portuguese ‘‘Montados’’ are manmade ecosystems, mainly used for cork production and cattle farming, that support a high biological diversity. Current sustainable management techniques imply a shrub clearing with heavy machinery, which can be highly disruptive for soil biota. In order to evaluate the effects of understory vegetation management on soil epigeic macrofauna, ﬁve zones were deﬁned along a chronosequence of shrub clearing: a non-disturbed zone (zone 5) and zones where understory vegetation was cut at 4–5 years (zone 4), at 3–4 years (zone 3), at 2 years (zone 2) and at 1 year (zone 1). A sixth zone (zone 6) was selected in a pasture, where cattle are occasionally present. Soil fauna was sampled using ‘‘pitfall’’ traps and sampling took place in autumn 2003. A total of 2,677 individuals, separated into 152 species and morphospecies, were caught in the traps. With the exception of zone 6, that presented a lower number of species, all the other zones from the chronosequence presented, in most cases, a similar number of taxa, species diversity (Shannon) and species richness (Margalef). Multivariate analysis separated recently disturbed zones (plus zone 6) from those intervened at longer time; groups like Formicidae, Scydmaenidae, most families from Araneae and insect larvae appeared closely associated to zones 3–5 (with a higher shrub cover and thick litter layers), whereas, other Hymenoptera, Gastropda and most Coleoptera families, appeared associated to recently disturbed zones (zones 1 and 2) and to zone 6, characterized by a lower shrub cover and a lower accumulation of litter. This separation indicates that effects of the intervention can endure for 2 or 3 years. After that time, the normal natural regeneration of the understory vegetation seems to support the restoration of the macrofauna community, thus indicating that the sustainable management strategy adopted, i.e., making a shrub cut every 5–6 years, seems not induce a signiﬁcant effect on local species richness of soil epigeic macrofauna.</style></abstract><issue><style face="normal" font="default" size="100%">2</style></issue></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Saitta, A.</style></author><author><style face="normal" font="default" size="100%">Bernicchia, A.</style></author><author><style face="normal" font="default" size="100%">Gorjón, S.

The evolution of the community physiognomy, composition and diversity were monitored after shrub clearing followed by biomass removal, deposition on soil surface and incorporation with the soil, over a 9-year period. Maximum shrub density was recorded in the ﬁrst year after the disturbances, excepting in mulched plots which showed the greatest number of individuals 1 year later. The increment of shrub leaf biomass was very fast in the ﬁrst 3 years, whereas wood production was slower but occurred along the whole study period. At the end of the study, leaf and wood biomass was still signiﬁcantly lower than in the predisturbance situation. The variation pattern of leaf area index was similar to that of leaf biomass. The evolution of total plant cover and diversity was similar across treatments. The highest species richness and diversity were recorded 2 years after cutting, decreasing afterwards with the increasing dominance of shrubs. Thus it seems likely that, although a 9 year period is too short for these communities to reach steady equilibrium, they are very resistant and resilient to disturbances, as regeneration was fast and vegetation dynamics was not inﬂuenced by differences among treatments. We can conclude that shrub clearing promotes biodiversity and the time of permanence of shrub patches depends on the particular goal we want to achieve.</style></abstract><issue><style face="normal" font="default" size="100%">2</style></issue></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Gálvez-Bravo, L.</style></author><author><style face="normal" font="default" size="100%">López-Pintor, A.</style></author><author><style face="normal" font="default" size="100%">Rebollo, S.</style></author><author><style face="normal" font="default" size="100%">Gómez-Sal, A.</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">European rabbit (Oryctolagus cuniculus) engineering effects promote plant heterogeneity in Mediterranean dehesa pastures</style></title><secondary-title><style face="normal" font="default" size="100%">Journal of Arid Environments</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Beta diversity</style></keyword><keyword><style  face="normal" font="default" size="100%">Biodiversity</style></keyword><keyword><style  face="normal" font="default" size="100%">Burrowing mammals</style></keyword><keyword><style  face="normal" font="default" size="100%">Floristic composition</style></keyword><keyword><style  face="normal" font="default" size="100%">latrines</style></keyword><keyword><style  face="normal" font="default" size="100%">Warrens</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2011</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2011///</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://linkinghub.elsevier.com/retrieve/pii/S0140196311001029</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">75</style></volume><pages><style face="normal" font="default" size="100%">779 - 786</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Mammalian herbivores can have dramatic effects on the vegetation through different mechanisms, and may therefore modify resource distribution or create habitat for other species. Organisms that cause such changes are classiﬁed as ecosystem engineers. The European rabbit (Oryctolagus cuniculus) is a semifossorial mammal native to the Iberian Peninsula and a keystone species in Mediterranean foodwebs. Rabbits are central-place foragers, but few studies have analysed their ecosystem engineering effects in the vicinity of warrens. Here, we explored the role of rabbits as ecosystem engineers in Mediterranean pastures in central Spain. We studied the spatial patterns and internal heterogeneity in the vegetation community of different spatial subunits created by rabbits (warrens, the warren inﬂuence area, and latrines). Within the different subunits, rabbit activities gave rise to patches and gradients with different plant species richness, diversity and height, and a high internal heterogeneity (dissimilarity) in ﬂoristic composition. Through different mechanisms, they have a signiﬁcant effect on species coexistence and competitive interactions, and increase the number of available niches for plants which otherwise would not be able to establish. In conclusion, rabbits can act as allogenic ecosystem engineers in Mediterranean pastures, increasing heterogeneity and contributing to the high biodiversity of Mediterranean annual pastures.</style></abstract><issue><style face="normal" font="default" size="100%">9</style></issue><notes><style face="normal" font="default" size="100%">The following values have no corresponding Zotero field:&lt;br/&gt;publisher: Elsevier Ltd</style></notes></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Romeralo, María</style></author><author><style face="normal" font="default" size="100%">Moya-Laraño, Jordi</style></author><author><style face="normal" font="default" size="100%">Lado, Carlos</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Social amoebae: environmental factors influencing their distribution and diversity across south-western Europe.</style></title><secondary-title><style face="normal" font="default" size="100%">Microbial ecology</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Biodiversity</style></keyword><keyword><style  face="normal" font="default" size="100%">Biological</style></keyword><keyword><style  face="normal" font="default" size="100%">Dictyosteliida</style></keyword><keyword><style  face="normal" font="default" size="100%">Dictyosteliida: classification</style></keyword><keyword><style  face="normal" font="default" size="100%">Dictyosteliida: genetics</style></keyword><keyword><style  face="normal" font="default" size="100%">Dictyosteliida: isolation &amp; purification</style></keyword><keyword><style  face="normal" font="default" size="100%">Dictyosteliida: physiology</style></keyword><keyword><style  face="normal" font="default" size="100%">Ecosystem</style></keyword><keyword><style  face="normal" font="default" size="100%">Models</style></keyword><keyword><style  face="normal" font="default" size="100%">Portugal</style></keyword><keyword><style  face="normal" font="default" size="100%">Soil</style></keyword><keyword><style  face="normal" font="default" size="100%">Soil: parasitology</style></keyword><keyword><style  face="normal" font="default" size="100%">SPAIN (citation)</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2011</style></year></dates><volume><style face="normal" font="default" size="100%">61</style></volume><pages><style face="normal" font="default" size="100%">154-165</style></pages><isbn><style face="normal" font="default" size="100%">0024801097</style></isbn><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">The social amoebae (dictyostelids) are the only truly multicellular lineage within the superkingdom Amoebozoa, the sister group to Ophistokonts (Metazoa+Fungi). Despite the exceptional phylogenetic and evolutionary value of this taxon, the environmental factors that determine their distribution and diversity are largely unknown. We have applied statistical modeling to a set of data obtained from an extensive and detailed survey in the south-western of Europe (The Iberian Peninsula including Spain and Portugal) in order to estimate some of the main environmental factors influencing the distribution and diversity of dictyostelid in temperate climates. It is the first time that this methodology is applied to the study of this unique group of soil microorganisms. Our results show that a combination of climatic (temperature, water availability), physical (pH) and vegetation (species richness) factors favor dictyostelid species richness. In the Iberian Peninsula, dictyostelid diversity is highest in colder and wet environments, indicating that this group has likely diversified in relatively cold places with high levels of water availability.</style></abstract><accession-num><style face="normal" font="default" size="100%">20614116</style></accession-num></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Caparros, A.</style></author><author><style face="normal" font="default" size="100%">Cerdá, E.</style></author><author><style face="normal" font="default" size="100%">Ovando, P.</style></author><author><style face="normal" font="default" size="100%">Campos, P.</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Carbon sequestration with reforestations and biodiversity-scenic values</style></title><secondary-title><style face="normal" font="default" size="100%">Environmental and Resource Economics</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Biodiversity</style></keyword><keyword><style  face="normal" font="default" size="100%">Carbon Accounting</style></keyword><keyword><style  face="normal" font="default" size="100%">Carbon Sequestration</style></keyword><keyword><style  face="normal" font="default" size="100%">Forests</style></keyword><keyword><style  face="normal" font="default" size="100%">Optimal Control</style></keyword><keyword><style  face="normal" font="default" size="100%">Scenic</style></keyword><keyword><style  face="normal" font="default" size="100%">Stated Preferences</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2010</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2010///</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://www.springerlink.com/index/g3385775170564n2.pdf</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">45</style></volume><pages><style face="normal" font="default" size="100%">49 - 72</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">This paper presents an optimal control model to analyze reforestations with two different species, including commercial values, carbon sequestration and biodiversity or scenic values. We solve the model qualitatively with general functions and discuss the implications of partial or total internalization of environmental values, showing that internalizing only carbon sequestration may have negative impacts on biodiversityscenic values. To evaluate the practical relevance, we compare reforestations in the South-west of Spain with cork-oaks (a slow growing native species) and with eucalyptus (a fast growing alien species). We do the analysis with two different carbon crediting methods: the Carbon Flow Method and the Ton Year Accounting Method. With the .first method forest surface increases more, but using mainly eucalyptus. With the second, additional reforestations are done mainly using cork-oaks. We value the impact on visitors of these reforestations using stated preferences methods, showing that when these values are internalized cork-oaks are favored.</style></abstract><issue><style face="normal" font="default" size="100%">I</style></issue></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">De Oliveira, Tatiana</style></author><author><style face="normal" font="default" size="100%">Hättenschwiler, Stephan</style></author><author><style face="normal" font="default" size="100%">Tanya Handa, Ira</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Snail and millipede complementarity in decomposing Mediterranean forest leaf litter mixtures</style></title><secondary-title><style face="normal" font="default" size="100%">Functional Ecology</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Biodiversity</style></keyword><keyword><style  face="normal" font="default" size="100%">diplopod</style></keyword><keyword><style  face="normal" font="default" size="100%">gastropod</style></keyword><keyword><style  face="normal" font="default" size="100%">litter consumption</style></keyword><keyword><style  face="normal" font="default" size="100%">non-additive effects</style></keyword><keyword><style  face="normal" font="default" size="100%">synergy</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2010</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2010///</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://dx.doi.org/10.1111/j.1365-2435.2010.01694.xhttp://doi.wiley.com/10.1111/j.1365-2435.2010.01694.x</style></url></web-urls></urls><publisher><style face="normal" font="default" size="100%">Blackwell Publishing Ltd</style></publisher><volume><style face="normal" font="default" size="100%">24</style></volume><pages><style face="normal" font="default" size="100%">937 - 946</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">1. The projected increase in loss of biodiversity worldwide has prompted the need to understand the role that diversity plays in key ecosystem functions such as litter decomposition and nutrient cycling. Here we asked how two contrasting species of saprophagous macrofauna and four Mediterranean forest leaf litter species interactively affect decomposition in a 6-week microcosm study. 2. Litter mass loss and macrofauna relative consumption rates (RCR) were measured on treatments with freshly fallen or partially decomposed leaf litter of Alnus glutinosa, Fraxinus angustifolia, Pistacia terebinthus and Quercus ilex as single-species or mixtures in absence and presence of the gastropod, Pomatias elegans, the diplopod, Glomeris marginata, or both macrofauna species. 3. Macrofauna consumed all litter substrates except freshly fallen P. terebinthus as a single-species litter that was fatal to both animals, although its presence in litter mixtures increased overall RCR. Consumption was higher in partially decomposed than freshly fallen litter, and higher in litter mixtures than in single-species litter. Both litter state and mixing interacted significantly with macrofauna treatment where generally, RCR by P. elegans alone was inferior to that of G. marginata alone or in combination with P. elegans. 4. An overall positive complementarity effect on litter RCR between G. marginata and P. elegans was observed in freshly fallen litter. Particularly strong complementarity was observed in two mixtures of freshly fallen litter and also in one mixture of partially decomposed litter. 5. There were no non-additive effects of litter mixing on litter mass loss in the absence of animals, indicating no interactions among litter substrates during decomposition. However, in the presence of either G. marginata and/or P. elegans, positive and negative interactions among litter substrates occurred and were enhanced or reversed by the addition of the second macrofauna species. 6.

By using single- and mixed-species leaf bags (7 possible combinations of three litter species differing in toughness; common alder [Alnus glutinosa ], sweet chestnut [Castanea sativa ], and Spanish oak [Quercus ilex ilex ]), I tested whether leaf species diversity, measured as richness and composition, affects breakdown dynamics and macroinvertebrate colonization (abundance, richness and composition) during 90 days incubation in a stream. Decomposition rates were additive, i.e., observed decomposition rates were not different from expected ones. However, decomposition rates of individual leaf species were affected by the mixture, i.e., there were species-specific responses to mixing litter. The invertebrate communities colonizing the mixtures were not richer and more diverse in mixtures than in single-species leaf bags. On the opposite, mixing leaf species had a negative, non-additive effect on rates of shredder and taxa colonization and on macroinvertebrate diversity. (© 2009 WILEY-VCH Verlag GmbH &amp; Co.

We selected eight types of forest ecosystems (ﬁve replicates or stands per forest type): pine (Pinus sylvestris) plantations of three age classes (10, 40 and 80 years since reforestation), an old-growth relict natural pine forest, and four types of oak (Quercus pyrenaica) stands: mature forests with livestock grazing and ﬁrewood extraction, mature forests where uses have been abandoned, ‘‘dehesa’’ ecosystems and shrubby oak ecosystems. The results obtained by a global PCA analysis indicated that both tree size and dominant species inﬂuenced the ordination of the 40 forest stands. In general, carabids were more sensitive to changes in forest heterogeneity and responded more clearly to the analysed structural variables than the understory vegetation, although the species richness of both groups was signiﬁ- cantly correlated and higher in case of oak forests. Pine forest ecosystems were characterised by the lowest species richness for both taxonomical groups, the lowest plant diversity and by the lowest coefﬁcients of variation and, consequently, low structural heterogeneity.

These landscapes have several core habitats and a different set of linear elements--habitat edges or ecotones, roads or railways, rivers, streams and hedgerows on farm land--whose plant composition were examined. Secondly, it aims to check plant diversity estimation in Mediterranean landscapes using parametric and non-parametric procedures, with two indices: Species richness and Shannon index. Land cover types and landscape linear elements were identified from aerial photographs. Their spatial information was processed using GIS techniques. Field plots were selected using a stratified sampling design according to relieve and tree density of each habitat type. A 50x20 m2 multi-scale sampling plot was designed for the core habitats and across the main landscape linear elements. Richness and diversity of plant species were estimated by comparing the observed field data to ICE (Incidence-based Coverage Estimator) and ACE (Abundance-based Coverage Estimator) non-parametric estimators. The species density, percentage of unique species, and alpha diversity per plot were significantly higher (p &lt; 0.05) in linear elements than in core habitats. ICE estimate of number of species was 32% higher than of ACE estimate, which did not differ significantly from the observed values.

We conducted eight experiments to examine whether goats offered different mixtures of shrubs containing different phytotoxins (tannins and saponins) would consume more shrub biomass than goats offered one shrub a single phytotoxin (tannin or saponin). In the first three experiments, goats fed a mixture of three tannin-rich shrubs (Quercus ilex, Arbutus unedo, and Pistacia lentiscus) ate more foliage than goats offered only one shrub (23.2 vs. 10.7 g/kg BW; 25.2 vs. 13.4 g/kg BW, and 27.9 vs. 7.9 g/kg BW), regardless of tannin concentration in individual shrub species. Goats also consumed more foliage when offered the same three tannin-rich shrubs than when offered the saponin-rich shrub Hedera helix (25.4 vs. 8.0 g/kg BW). However, goats offered a mixture of the same three tannin-rich shrubs consumed less foliage than goats offered a mixture of two shrubs containing tannins and saponins: Quercus and Hedera (21.6 vs. 27.1 g/kg BW), Arbutus and Hedera (21.8 vs. 27.1 g/kg BW), and Pistacia and Hedera (19.7 vs. 22.0 g/kg BW). Comparison of intake of shrubs containing only tannins or saponins to intake of shrubs containing both tannins and saponins indicated that goats consumed more total biomass when fed with shrubs with both classes of compounds than with either tannins or saponins alone. Our results suggest that goats can increase intake of Mediterranean shrubs high in secondary compounds by selecting those with different classes of phytotoxins. Simultaneous ingestion of shrubs containing tannins and saponins may promote chemical interactions that inhibit toxic effects of these phytotoxins in the intestinal tract. In addition to complementary interactions between tannins and saponins, biological diversity within Mediterranean maquis vegetation also plays a positive role in increasing shrub intake by goats.</style></abstract><issue><style face="normal" font="default" size="100%">6</style></issue><notes><style face="normal" font="default" size="100%">The following values have no corresponding Zotero field:&lt;br/&gt;accession-num: 16770718</style></notes></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Rogosic, Jozo</style></author><author><style face="normal" font="default" size="100%">Estell, Richard E</style></author><author><style face="normal" font="default" size="100%">Skobic, Dragan</style></author><author><style face="normal" font="default" size="100%">Martinovic, Anita</style></author><author><style face="normal" font="default" size="100%">Maric, Stanislava</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Role of species diversity and secondary compound complementarity on diet selection of Mediterranean shrubs by goats.</style></title><secondary-title><style face="normal" font="default" size="100%">Journal of chemical ecology</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Biodiversity</style></keyword><keyword><style  face="normal" font="default" size="100%">Goats</style></keyword><keyword><style  face="normal" font="default" size="100%">Maquis</style></keyword><keyword><style  face="normal" font="default" size="100%">Mediterranean shrubs</style></keyword><keyword><style  face="normal" font="default" size="100%">Saponins</style></keyword><keyword><style  face="normal" font="default" size="100%">Secondary compounds</style></keyword><keyword><style  face="normal" font="default" size="100%">Tannins</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2006</style></year></dates><volume><style face="normal" font="default" size="100%">32</style></volume><pages><style face="normal" font="default" size="100%">1279-1287</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Goats foraging on Mediterranean shrubs containing secondary compounds (toxins) may consume a variety of shrubs that contain different phytotoxins, thereby increasing shrub intake and avoiding toxicosis.

We discuss the role of soil seed banks in the vegetation dynamics and in the complete plant biodiversity of the mosaic landscape studied.</style></abstract><issue><style face="normal" font="default" size="100%">5</style></issue></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Scarascia-Mugnozza, Giseppe</style></author><author><style face="normal" font="default" size="100%">Oswald, Helfried</style></author><author><style face="normal" font="default" size="100%">Piussi, Pietro</style></author><author><style face="normal" font="default" size="100%">Radoglou, Kalliopi</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Forests of the Mediterranean region: gaps in knowledge and research needs</style></title><secondary-title><style face="normal" font="default" size="100%">Forest Ecology and Management</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Biodiversity</style></keyword><keyword><style  face="normal" font="default" size="100%">forest ecosystems</style></keyword><keyword><style  face="normal" font="default" size="100%">Mediterranean Region</style></keyword><keyword><style  face="normal" font="default" size="100%">silviculture</style></keyword><keyword><style  face="normal" font="default" size="100%">sustainable management</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2000</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2000///</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://linkinghub.elsevier.com/retrieve/pii/S0378112700003832</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">132</style></volume><pages><style face="normal" font="default" size="100%">97 - 109</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Mediterranean forests are characterised by a remarkable set of features that make them naturally and aesthetically attractive, on the one hand, but also quite fragile, on the other, therefore calling for careful strategies for their conservation and management.

Three contrasted landscapes were chosen in terms of human land use and vegetation structure: an intensive farmland, a pine plantation, and a matoral. The roadside sections varied in vegetation structure, width and profile. We recorded birds present in roadsides and adjacent habitats by transect counts over all seasons. Roadside bird species appeared for a great part similar to those of adjacent habitats. However, diversity and abundance in verges did not depend on that of adjacent habitats. Woody roadsides were compararable to hedges, as trees (and shrubs) in verges enhanced species richness and abundance of birds in the farmland and woodland sites. Width and profile of verges had less influence. In all sites, typical species of the habitat traversed partly avoided roadsides. On the contrary, numerous species associated with ‘rare’ habitats in one site preferred roadsides, provided that verge vegetation contrasted with the dominant habitat. It is concluded that birds responses to highways can vary greatly with landscape traversed and verge vegetation. Highway verges could be favorable to birds, if they constitute a complementary habitat to the dominant habitat within a landscape</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Coûteaux, Marie-Madeleine</style></author><author><style face="normal" font="default" size="100%">Kurz, Cathy</style></author><author><style face="normal" font="default" size="100%">Bottner, Pierre</style></author><author><style face="normal" font="default" size="100%">Raschi, Antonio</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Influence of increased atmospheric CO2 concentration on quality of plant material and litter decomposition</style></title><secondary-title><style face="normal" font="default" size="100%">Tree Physiology</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Biodiversity</style></keyword><keyword><style  face="normal" font="default" size="100%">Carbon dioxide</style></keyword><keyword><style  face="normal" font="default" size="100%">Global change</style></keyword><keyword><style  face="normal" font="default" size="100%">lignin content</style></keyword><keyword><style  face="normal" font="default" size="100%">nitrogen content</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">1999</style></year></dates><volume><style face="normal" font="default" size="100%">19</style></volume><pages><style face="normal" font="default" size="100%">301-311</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Nitrogen (N) and lignin concentrations in plant tissues and litter of plants grown in greenhouses or open-top chambers in elevated atmospheric CO2 concentration were compared with those of plants grown in ambient air in short-term studies.

Foliage transparency, leaf damage and crown dieback have changed significantly over the monitoring period. Leaf area, length of the current year shoots, and total leaf area changed as well, but only for Turkey oak. Changes were consistent between and within the plots. Different indices of plant diversity showed marked changes, apparently linked to natural dynamics within individual ecosystems.

Trends in species composition and cover were analysed by Detrended Correspondence Analysis; the first axis, assumed to reflect a main environmental gradient, was used to analyse the patterns of three aspects of community diversity. Species richness, i.e. number of species along a 100-m transect, shows a humpbacked trend along the gradient, with the highest values in the understorey of evergreen Quercus suber woodlands, associated with soils of intermediate fertility and moisture status. The number of endemic species is highest in open heathlands, associated with more extreme conditions of acid, infertile soils on exposed ridges. The taxonomic singularity, as measured by the inverse of the average number of species per genus at each site, is highest at the most fertile and moist sites occupied by semideciduous Q. canariensis woodlands. A comparison between northern (Spanish) and southern (Moroccan) sides of the Strait of Gibraltar shows a general concordance of the trends of woody plant communities along the main environmental gradient. However, significant differences of the southern samples are: (1) lack of some differential, habitat-specific species and greater abundance of wide spread generalists; and (2) a general reduction in species diversity, number of endemics and taxonomic singularity. We interpret these differences as affected partly by the smaller extent and fragmentation of sandstone areas in the south, and partly by the higher impact of slashing and grazing there.</style></abstract></record></records></xml>
