In such places, farmland abandonment represents a signiﬁcant land use change from cropping to a complex of plant successions. The present study assesses the hydromorphological effects of land abandonment in Europe, and the consequences thereof with respect to water resource availability and soil erosion. The evolution of abandoned ﬁelds depends on (i) the time of abandonment; (ii) climatic conditions in the abandoned area; (iii) particular characteristics of the ﬁelds; (iv) the land management regimen following abandonment; and, (v) the role played by government policy. Throughout most of Europe, vegetation on abandoned farmland has evolved into dense forest or shrub. The expansion of vegetation explains, in part, the perceived decline in water resources, reductions in soil loss and sediment delivery, and the progressive improvement of soil characteristics. Such evolution has resulted in changing stream morphology, featuring narrowing and incision, and a decline in sedimentation level in Mediterranean reservoirs. The abandonment of bench terrace ﬁelds coincided with an increase in the occurrence of small landslides in the steps between terraces, as well as changes in the spatial organization of saturated areas. Plant colonization is slower in semiarid areas, increasing the development of soil crusts that reduce inﬁltration and increase overland ﬂow. Land policies with detailed capability are necessary to remediate the consequences of farmland abandonment in various European environments.</style></abstract><issue><style face="normal" font="default" size="100%">3-4</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%">Bakker, Martha M.</style></author><author><style face="normal" font="default" size="100%">Govers, Gerard</style></author><author><style face="normal" font="default" size="100%">van Doorn, Anne</style></author><author><style face="normal" font="default" size="100%">Quetier, Fabien</style></author><author><style face="normal" font="default" size="100%">Chouvardas, Dimitris</style></author><author><style face="normal" font="default" size="100%">Rounsevell, Mark</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">The response of soil erosion and sediment export to land-use change in four areas of Europe: The importance of landscape pattern</style></title><secondary-title><style face="normal" font="default" size="100%">Geomorphology</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">EUROPE</style></keyword><keyword><style  face="normal" font="default" size="100%">Land-use change</style></keyword><keyword><style  face="normal" font="default" size="100%">landscape pattern</style></keyword><keyword><style  face="normal" font="default" size="100%">soil erosion</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2008</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2008///</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://linkinghub.elsevier.com/retrieve/pii/S0169555X07002292</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">98</style></volume><pages><style face="normal" font="default" size="100%">213 - 226</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">The response of erosion and sediment export to past land-use change has been studied in four agricultural areas of Europe. Three of these areas were subject to land abandonment or de-intensification and one to intensification of land-use practices. Erosion and sediment yield were modeled using the WaTEM/SEDEM model, which combines the RUSLE equation with a sediment routing algorithm. Spatial relationships between the RUSLE C-factor (i.e. land-use) and other erosion and sediment exportdetermining factors (slope, soil erodibility and distance to rivers) were investigated, as these account for non-linearity in the response of erosion and sediment export to land-use change. Erosion and sediment export have decreased enormously in the de-intensified areas, but slightly increased in the intensively cultivated area. The spatial pattern of land-use change in relation to other erosion and sediment export-determining factors appears to have a large impact on the response of soil erosion and sediment export to land-use change. That the drivers of abandonment of arable land and erosion coincide indicates that de-intensification leads to a more favourable landscape pattern with respect to reduction of erosion and sediment export. This mechanism applies not only within the study areas, but also among the European study areas where the process of intensification of some areas and de-intensification of others might result in an overall decrease of erosion and sediment yield through time</style></abstract><issue><style face="normal" font="default" size="100%">3-4</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 Rancourt, M.</style></author><author><style face="normal" font="default" size="100%">Fois, N.</style></author><author><style face="normal" font="default" size="100%">Lavín, M.

Our article aims at comparing the situation of the main small ruminant systems in South European regions (Spain, France, Italy and Greece), and their possible future evolution. On the average, the income of milk systems tends to be higher than meat systems thanks to a good market price. Moreover, the dependence on subsidies is greater in meat systems and in extensive systems. However, milk systems seem more sensitive to the market situation for example, Italian products in the USA and products from Greece with respect to certain foreign companies. Sheep and goat production, being frequently the only possible enterprises in less favoured areas, are often fundamental to maintaining social activities and to keep the vegetation out of danger from fire. However, in Greece and Spain some intensive systems are becoming established in the more fertile plain areas. The roads to success are rather uncertain considering the new CAP reform as nearly all these systems seem to be dependent on the important European subsidies. Nevertheless, we have identified different ways to progress according to systems and regions. Such an uncertain future could be easier to forecast if those involved in the sheep and goat sectors worked more collectively in Europe.</style></abstract><issue><style face="normal" font="default" size="100%">3</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%">Stone, G.</style></author><author><style face="normal" font="default" size="100%">Atkinson, R.</style></author><author><style face="normal" font="default" size="100%">Rokas, A.</style></author><author><style face="normal" font="default" size="100%">Csoka, G.</style></author><author><style face="normal" font="default" size="100%">Nieves-Aldrey, J.

In Eastern Europe and Turkey, the lifecycle involves a sexual generation on Turkey oak, Quercus cerris, while in Iberia and North Africa the sexual generation host is cork oak, Q. suber. Over the last 500 years, A. kollari has expanded its range into northern Europe, following human planting of Q. cem's from Italy and the Balkans. We ask: (i) what is the genetic relationship between eastern and western distributions of Andricus kollari? Can we determine which lifecycle is ancestral, and how long ago they diverged? (ii) To what extent have eastern and western native ranges contributed to northwards range expansion? (iii) Is there any evidence for hybridization between the two life cycle types? We present analyses of allozyme data for 13 polymorphic loci and of sequence variation for a 433 bp fragment of the mitochondrial cytochrome b gene. These show: (i) that four haplotype lineages (one in Spain, two in Hungary/Italy and one in Turkey) diverged more or less simultaneously between 1 and 2 million years ago, suggesting the existence of at least four refuges through recent ice age cycles. Our data cannot resolve which lifecycle type is ancestral. (ii) Populations north of putative refuges are divided into two sets. Populations in south-west France are allied to Spain, while ail remaining populations in northern Europe have been colonized from Italy and the Balkans. (iii) The transition from one race to another in south-west France is marked by abrupt transitions in the frequency of refuge-specific private alleles and corresponds closely to the northern limit of the distribution of cork oak. Although hybrids were detected in north-west France, none were detected where the two lifecycles meet in south-western France. The biology of oak gallwasps predicts that any hybrid zone will be narrow and limited to regions where Q. cem's and Q. suber meet. Our data suggest that eastern and western A. kollari are effectively separate species.</style></abstract><issue><style face="normal" font="default" size="100%">3</style></issue><notes><style face="normal" font="default" size="100%">From Duplicate 2 (Differential success in northwards range expansion between ecotypes of the marble gallwasp Andricus kollari: a tale of two lifecycles - Stone, G; Atkinson, R; Rokas, A; Csoka, G; Nieves-Aldrey, J L)From Duplicate 2 (Differential success in northwards range expansion between ecotypes of the marble gallwasp Andricus kollari: a tale of two lifecycles - Stone, G; Atkinson, R; Rokas, A; Csoka, G; Nieves-Aldrey, J L)The following values have no corresponding Zotero field:&lt;br/&gt;pub-location: COMMERCE PLACE, 350 MAIN ST, MALDEN 02148, MA USA&lt;br/&gt;publisher: WILEY-BLACKWELL&lt;br/&gt;accession-num: 11298986</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%">ARBEZ, M.</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">BASIS AND ORGANIZATION OF THE EUROPEAN FOREST TREE GENE CONSERVATION NETWORKS</style></title><secondary-title><style face="normal" font="default" size="100%">GENETICS SELECTION EVOLUTION</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">EUROPE</style></keyword><keyword><style  face="normal" font="default" size="100%">FOREST</style></keyword><keyword><style  face="normal" font="default" size="100%">GENETIC RESOURCE</style></keyword><keyword><style  face="normal" font="default" size="100%">INTERNATIONAL COOPERATION</style></keyword><keyword><style  face="normal" font="default" size="100%">NETWORK</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">1994</style></year><pub-dates><date><style  face="normal" font="default" size="100%">1994///</style></date></pub-dates></dates><volume><style face="normal" font="default" size="100%">26</style></volume><pages><style face="normal" font="default" size="100%">S301 - S314</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">The first ministerial conference on the protection of forests in Europe, held in Strasbourg in 1990, engaged 32 signatory countries to initiate or to follow a concerted policy for forest tree gene conservation and to establish a provisional monitoring structure. This resolution has resulted in an international survey on the present status of forest tree genetic resources in Europe and relevant technical and regulatory measures. In parallel the first 4 pilot gene conservation networks concerning Norway spruce (Picea abies), Cork oak (Quercus suber), black poplar (Populus nigra) and the noble hardwoods (Rosaceaes essentially) were established. Each species or group of species represents a distinct model of spatial distribution and mating system. The second ministerial conference on the protection of forests, held in Helsinki in June 1993, has confirmed these orientations and has proposed the creation of a permanent European cooperative programme under the aegis of the International Board for Plant Genetic Resources and the forest department of the Food and Agriculture Organization. Further research is necessary on the structure of the genetic variability, the mechanisms to maintain this variability in natural forests, and management and sylvicultural methods able to generate maximum adaptability.</style></abstract><issue><style face="normal" font="default" size="100%">1</style></issue><notes><style face="normal" font="default" size="100%">The following values have no corresponding Zotero field:&lt;br/&gt;pub-location: 141 RUE JAVEL, 75747 PARIS CEDEX 15, FRANCE&lt;br/&gt;publisher: EDITIONS SCIENTIFIQUES ELSEVIER</style></notes></record></records></xml>
