Brullo, D'Emerico and Pulv. sp. nov., is described and illustrated. It is a nemoral species, occurring in Holm oak woods, and is characterized by a diploid chromosome complement of 2n = 2x = 38. In the metaphase I, the mother cells of the embryo sac contain 19 bivalents. With respect to morphology and karyotype structure, the new species shows a close relationships with E. helleborine and other allied species, such as E. meridionalis and E. schubertiorum, both occurring in southern Italy and Sicily. However, several morphological features, chromosome size, and differences in the heterochromatin distribution allow for a clear distinction between E. cupaniana and the above-mentioned species.</style></abstract><issue><style face="normal" font="default" size="100%">5</style></issue><notes><style face="normal" font="default" size="100%">APSAPSThe following values have no corresponding Zotero field:&lt;br/&gt;pub-location: 111 RIVER ST, HOBOKEN 07030-5774, NJ USA&lt;br/&gt;publisher: WILEY-BLACKWELL</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%">Calò, Camilla</style></author><author><style face="normal" font="default" size="100%">Henne, Paul D.</style></author><author><style face="normal" font="default" size="100%">Curry, Brandon</style></author><author><style face="normal" font="default" size="100%">Magny, Michel</style></author><author><style face="normal" font="default" size="100%">Vescovi, Elisa</style></author><author><style face="normal" font="default" size="100%">La Mantia, Tommaso</style></author><author><style face="normal" font="default" size="100%">Pasta, Salvatore</style></author><author><style face="normal" font="default" size="100%">Vannière, Boris</style></author><author><style face="normal" font="default" size="100%">Tinner, Willy</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Spatio-temporal patterns of Holocene environmental change in southern Sicily</style></title><secondary-title><style face="normal" font="default" size="100%">Palaeogeography, Palaeoclimatology, Palaeoecology</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">climate change</style></keyword><keyword><style  face="normal" font="default" size="100%">Holocene</style></keyword><keyword><style  face="normal" font="default" size="100%">Mediterranean</style></keyword><keyword><style  face="normal" font="default" size="100%">paleoecology</style></keyword><keyword><style  face="normal" font="default" size="100%">Paleohydrology</style></keyword><keyword><style  face="normal" font="default" size="100%">Sicily</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://linkinghub.elsevier.com/retrieve/pii/S0031018212000624</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">323-325</style></volume><pages><style face="normal" font="default" size="100%">110 - 122</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Few examples of natural forest remain near the Mediterranean coast. Therefore, it is difﬁcult to study how coastal forests respond to climatic change or their resilience to human impact. We developed new sedimentary record of Holocene vegetation and ﬁre history at Lago Preola, a coastal lake in southwestern Sicily (Italy). In order to verify the existence of forest at large scale on the coast, we compare pollen from Lago Preola, a medium-sized lake (33 ha), to Gorgo Basso, a small lake (3 ha) located nearby with the aim of separating local from extra-local vegetation dynamics through time using pollen percentages and inﬂux. We then compare Lago Preola pollen to the record from Biviere di Gela, a large lagoon (120 ha) situated 160 km to the east in southern Sicily, to examine differences in vegetation dynamics between the two coastal areas during the Holocene. Lake-level reconstructions and ostracode analyses from Lago Preola provide vegetation-independent evidence of climate change, and help to disentangle human and climatic impacts on vegetation. Pollen data indicate Pistacia-dominated shrublands replaced open grasslands in the region surrounding Lago Preola by 9500 cal yr BP. This change coincided with rising lake levels and the development of an ostracode fauna typical of fresh waters. Evergreen forest dominated by Quercus ilex and Olea europaea started to expand by 7000 cal BP and consolidated at 6500 cal yr BP, when lake levels were near their Holocene high. Similarities between pollen from Lago Preola and Gorgo Basso demonstrate that forest was the dominant vegetation type in coastal Sicily during the middle Holocene at both regional and local scales, and even developed in the drier climatic setting around Biviere di Gela. Lake levels fell at Lago Preola after 7000 cal yr BP, with a strong decline accompanied by increasing salinity after 4500 cal yr BP. However, no transition in vegetation matched these inferred hydrological changes. Instead, forests persisted in the surrounding region until 2200 cal BP when human disturbance intensiﬁed. We propose that different climatic factors control lake levels and vegetation in coastal Mediterranean ecosystems. Whereas lake levels are most sensitive to the abundance of winter precipitation, coastal forests depend on spring precipitation and are limited by the length of summer drought. Moisture availability remained suitable for evergreen forests in coastal Sicily during the late Holocene, and humans, not a drier climate drove the regional forest decline.</style></abstract><notes><style face="normal" font="default" size="100%">The following values have no corresponding Zotero field:&lt;br/&gt;publisher: Elsevier B.V.</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%">La Mantia, T</style></author><author><style face="normal" font="default" size="100%">Rühl, J</style></author><author><style face="normal" font="default" size="100%">Pasta, S</style></author><author><style face="normal" font="default" size="100%">Campisi, D G</style></author><author><style face="normal" font="default" size="100%">Terrazzino, G</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Structural analysis of woody species in Mediterranean old fields</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%">Abandonment</style></keyword><keyword><style  face="normal" font="default" size="100%">landscape conservation</style></keyword><keyword><style  face="normal" font="default" size="100%">Secondary succession</style></keyword><keyword><style  face="normal" font="default" size="100%">Sicily</style></keyword><keyword><style  face="normal" font="default" size="100%">Spatial pattern</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2008</style></year></dates><publisher><style face="normal" font="default" size="100%">Taylor &amp; Francis</style></publisher><volume><style face="normal" font="default" size="100%">142</style></volume><pages><style face="normal" font="default" size="100%">462-471</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Abstract The study analyses the changes in vegetation structure and composition within a sere of secondary succession at Pantelleria Island (Sicilian Channel, Italy). It aims to show that not only phytosociological data but also structural parameters, like woody species? height and spatial distribution indices are useful to describe and interpret renaturation processes. Woody species structure was recorded on abandoned terraces, both on north-facing and on south-facing slopes. Relevés were made in fallows representing five different stages of succession. The pace of succession, measured through the analysis of woody species cover, basal area, height distribution and spatial indices, resulted quite rapid: already after 50 years of abandonment terraces are covered by dense maquis communities. Our study also revealed that different plant species or groups prevail during colonisation dynamics, mostly depending on exposition, a factor which strongly influences also the speed of colonisation by woody species. In this case study, human activity seems to be unnecessary to accelerate the process of renaturation, except in some unfavourable contexts. Species turnover rate, biodiversity value, and structural evolution along progressive succession must be taken into account in nature management and conservation policies of terraced landscapes, which are nowadays one of the most endangered landscape types throughout the Mediterranean area.</style></abstract><notes><style face="normal" font="default" size="100%">doi: 10.1080/11263500802410793</style></notes><research-notes><style face="normal" font="default" size="100%">doi: 10.1080/11263500802410793</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%">Sarà, Maurizio</style></author><author><style face="normal" font="default" size="100%">Bellia, Enrico</style></author><author><style face="normal" font="default" size="100%">Milazzo, Andrea</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Fire disturbance disrupts co-occurrence patterns of terrestrial vertebrates in Mediterranean woodlands</style></title><secondary-title><style face="normal" font="default" size="100%">Journal of Biogeography</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Community disruption</style></keyword><keyword><style  face="normal" font="default" size="100%">Madonie Park</style></keyword><keyword><style  face="normal" font="default" size="100%">Mediterranean belt</style></keyword><keyword><style  face="normal" font="default" size="100%">null models</style></keyword><keyword><style  face="normal" font="default" size="100%">perturbation</style></keyword><keyword><style  face="normal" font="default" size="100%">Sicily</style></keyword><keyword><style  face="normal" font="default" size="100%">species co-occurrence</style></keyword><keyword><style  face="normal" font="default" size="100%">terrestrial vertebrates</style></keyword><keyword><style  face="normal" font="default" size="100%">wildfires</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2006</style></year></dates><publisher><style face="normal" font="default" size="100%">Blackwell Publishing Ltd</style></publisher><volume><style face="normal" font="default" size="100%">33</style></volume><pages><style face="normal" font="default" size="100%">843-852</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Aim This paper uses null model analysis to explore the pattern of species co-occurrence of terrestrial vertebrate fauna in fire-prone, mixed evergreen oak woodlands. Location The Erico–Quercion ilicis of the Mediterranean belt (50–800 m a.s.l.) in the Madonie mountain range, a regional park in northern Sicily (37°50′ N, 14°05′ E), Italy. Methods The stratified sampling of vertebrates in a secondary succession of recent burned areas (BA, 1–2 years old), intermediate burned areas (INT, 4–10 years old) and ancient burned areas (CNB, &gt; 50 years old), plus forest fragments left within burned areas (FF, 1–2 years old) permitted the comparison of patterns of species co-occurrence using a set of separate presence/absence matrices. First, the breeding avifauna derived from standardized point counts was analysed using Stone &amp; Roberts’C-score, and by a null model algorithm (fixed/equiprobable). Secondly, the analysis was repeated using all vertebrate species recorded in the succession. Results Sixty-five species were recorded in the 2-year study period in the four sample treatments. Birds were found to make up the largest component (63%) of the recorded assemblage. The BA treatment had the lowest species richness, followed in order by the small, medium and large FFs, and then by the CNBs. For both analyses (birds and total vertebrates), the C-scores were quite small and not significantly different from those that could be expected by chance in the BA and INT burned areas; this indicates a random co-occurrence among vertebrates of those assemblages. Contrariwise, for both analyses in the CNBs, the C-scores were large and significantly different from the simulated indices, thereby indicating a non-random co-occurrence pattern (segregation) of vertebrates in the undisturbed woodlands. In addition, C-score values for the surviving FFs show a significant aggregation of species. Main conclusions The null model analyses highlighted a new aspect of fire disturbance in Mediterranean woodland ecosystems: the disruption in patterns of co-occurrence in the terrestrial vertebrate community. Wildfire alters community organization, inducing, for at least 10 years, a random aggregate of species. Communities re-assemble themselves, showing the occurrence of species segregation at least 50 years after fire.</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%">Sarà, Maurizio</style></author><author><style face="normal" font="default" size="100%">Bellia, Enrico</style></author><author><style face="normal" font="default" size="100%">Milazzo, Andrea</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Fire disturbance disrupts co-occurrence patterns of terrestrial vertebrates in Mediterranean woodlands</style></title><secondary-title><style face="normal" font="default" size="100%">Journal of Biogeography</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Community disruption</style></keyword><keyword><style  face="normal" font="default" size="100%">Madonie Park</style></keyword><keyword><style  face="normal" font="default" size="100%">Mediterranean belt</style></keyword><keyword><style  face="normal" font="default" size="100%">null models</style></keyword><keyword><style  face="normal" font="default" size="100%">perturbation</style></keyword><keyword><style  face="normal" font="default" size="100%">Sicily</style></keyword><keyword><style  face="normal" font="default" size="100%">species co-occurrence</style></keyword><keyword><style  face="normal" font="default" size="100%">terrestrial vertebrates</style></keyword><keyword><style  face="normal" font="default" size="100%">wildfires</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2006</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2006///</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://dx.doi.org/10.1111/j.1365-2699.2006.01429.x</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">33</style></volume><pages><style face="normal" font="default" size="100%">843 - 852</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Aim This paper uses null model analysis to explore the pattern of species co-occurrence of terrestrial vertebrate fauna in fire-prone, mixed evergreen oak woodlands.
