Genets demonstrate flexibility in habitat use and select habitats using different criteria depending on the scale of analysis, although they show clear selection for habitats formed by forest areas with a tree layer and dense underbrush vegetation cover. Vegetation cover is the most important factor determining habitat selection across all scales. Selections within home range and core area are very similar, with genets showing a preference for pine forest, ravine and holm oak forest over other habitat types (crops, lowland sparse, maquis vegetation and anthropized areas). In resting sites, genets show a strong preference for ravines. Ravine was also the only habitat that is present in the home ranges and core areas of all individuals. Vegetation-associated ravines provide the most cover of all available habitats, and therefore we conclude that these habitats are selected by genets to provide the resources they need. We recommend that management should maintain vegetation cover to preserve the populations of genets.</style></abstract><issue><style face="normal" font="default" size="100%">3</style></issue><notes><style face="normal" font="default" size="100%">The following values have no corresponding Zotero field:&lt;br/&gt;pub-location: GENTHINER STRASSE 13, D-10785 BERLIN, GERMANY&lt;br/&gt;publisher: WALTER DE GRUYTER GMBH</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%">Pereira, Marian</style></author><author><style face="normal" font="default" size="100%">Rodríguez, Alejandro</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Conservation value of linear woody remnants for two forest carnivores in a Mediterranean agricultural landscape</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%">agri-environmental schemes</style></keyword><keyword><style  face="normal" font="default" size="100%">agroecosystems</style></keyword><keyword><style  face="normal" font="default" size="100%">Biodiversity conservation</style></keyword><keyword><style  face="normal" font="default" size="100%">Connectivity</style></keyword><keyword><style  face="normal" font="default" size="100%">farmland</style></keyword><keyword><style  face="normal" font="default" size="100%">genetta genetta</style></keyword><keyword><style  face="normal" font="default" size="100%">habitat selection</style></keyword><keyword><style  face="normal" font="default" size="100%">hedgerows</style></keyword><keyword><style  face="normal" font="default" size="100%">Herpestes ichneumon</style></keyword><keyword><style  face="normal" font="default" size="100%">landscape restoration</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://doi.wiley.com/10.1111/j.1365-2664.2010.01804.x</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">47</style></volume><pages><style face="normal" font="default" size="100%">611 - 620</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">1. The loss of biodiversity caused by agricultural expansion can be countered by adopting wildlifefriendly farming strategies and by expanding the network of nature reserves. The potential beneﬁts of agricultural extensiﬁcation, represented in Europe by agri-environmental schemes, still remain unclear. In particular, the eﬀectiveness of preserving linear woody vegetation to retain forest carnivores in farmland has received limited attention. We document the value of hedgerows and narrow strips of riparian forest for the Egyptian mongoose Herpestes ichneumon and the common genet Genetta genetta. 2. In an agricultural mosaic of southern Spain containing 4Æ7% of woody vegetation, we tested hypotheses about the role of linear elements and three farmland types diﬀering in the amount, quality and structure of woody cover. We analysed the inﬂuence of linear elements on the placement and utilization of home ranges by combining compositional analysis and numerical methods. 3. Mongooses and genets strongly selected linear woody vegetation. All types of farmland, including open ﬁelds, dehesa (savanna-like pastureland or arable land rich in oak trees Quercus ilex and Q. suber) and olive Olea europaea groves, were avoided, suggesting that both species strictly depend upon native woody cover. 4. Most individuals made regular use of hedgerows and some individuals used hedgerows as the only source of woody cover in their home ranges. 5. The distribution of home ranges suggested that individuals made up a continuous, rather than discrete, population in a spatially structured habitat. An evenly distributed hedgerow network across the intervening agricultural matrix could prevent population fragmentation. 6. Synthesis and applications. A suitable network of linear cover allows some forest carnivores to survive in agricultural landscapes containing a low proportion (&lt;10%) of native woody vegetation. Length (&gt;0Æ5 km), width (4–10 m), quality (continuous native shrubs, scattered native trees, low levels of human disturbance), density (10–50 m ha )1 ) and a regular distribution of linear features are key elements in the conservation or restoration of agricultural landscapes where the preservation of small forest carnivores is an objective.</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%">Santilli, Francesco</style></author><author><style face="normal" font="default" size="100%">Bagliacca, Marco</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">HABITAT USE BY THE EUROPEAN WILD RABBIT (ORYCTOLAGUS CUNICULUS) IN A COASTAL SANDY DUNE ECOSYSTEM OF CENTRAL ITALY</style></title><secondary-title><style face="normal" font="default" size="100%">HYSTRIX-ITALIAN JOURNAL OF MAMMALOGY</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">coastal dunes</style></keyword><keyword><style  face="normal" font="default" size="100%">habitat selection</style></keyword><keyword><style  face="normal" font="default" size="100%">Italy</style></keyword><keyword><style  face="normal" font="default" size="100%">wild rabbit</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2010</style></year></dates><publisher><style face="normal" font="default" size="100%">ASSOC TERIOLOGICA ITAL</style></publisher><pub-location><style face="normal" font="default" size="100%">C/O CLAUDIO PRIGIONI, DEPT BIOLOGIA ANIMALE, UNIV PAVIA, PIAZZA BOTTA 9, PAVIA, I-56126, ITALY</style></pub-location><volume><style face="normal" font="default" size="100%">21</style></volume><pages><style face="normal" font="default" size="100%">57-64</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">The European wild rabbit (Oryctolagus cuniculus) has been recurrently introduced into Italy since the Roman times. Some populations occur along sandy coastal dunes (Central Italy). There is no information about the ecology and habitat preferences of wild rabbits in this particular ecosystem. During May and June 2009, we assessed the distribution of wild rabbits in a 120 ha protected area (province of Livorno, Tuscany), by faecal pellet counts in 170 circular plots (d = 1 m). Range size defined by Kernel Analysis was 27.3 ha (95%) and 13.2 ha (50%). Habitat selection was assessed through Jacobs' index of selection. Rabbits selected the first dunes that offer both food (psammophilous grasses) and the cover of tamarisk shrubs. Holm oak woods and pinewoods were avoided, probably because of the lack of undergrowth.</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%">Ciudad, Carlos</style></author><author><style face="normal" font="default" size="100%">Robles, Hugo</style></author><author><style face="normal" font="default" size="100%">Matthysen, Erik</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Postfledging habitat selection of juvenile middle spotted woodpeckers: a multi-scale approach</style></title><secondary-title><style face="normal" font="default" size="100%">Ecography</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">foraging habitat use</style></keyword><keyword><style  face="normal" font="default" size="100%">habitat selection</style></keyword><keyword><style  face="normal" font="default" size="100%">juvenile birds</style></keyword><keyword><style  face="normal" font="default" size="100%">oak forests</style></keyword><keyword><style  face="normal" font="default" size="100%">postfledging (voyant)</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2009</style></year></dates><volume><style face="normal" font="default" size="100%">32</style></volume><pages><style face="normal" font="default" size="100%">676-682</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Despite its relevance for the persistence of populations, the ecological mechanisms underlying habitat use decisions of juvenile birds are poorly understood.

Variables considered in the analysis included presence or absence of cattle; ground vegetation coverage, height and vertical density; tree density; bush coverage; slope exposition; stone coverage and number of stones; wind direction; habitat; soil capacity; distance to roads, drinking places and villages; and altitude. . Results: The results of biotope selection indicated that sandgrouses preferred fields of leguminous plants during both breeding and non-breeding periods and tillage during the breeding period. Montado and fallows older than two years were avoided during the non-breeding season. Cereal fields were used according to their availability. Besides not significantly, fallows were highly used.

During the non-breeding period, the model was not adjusted to validation sample. Conclusions: It was found that the most important biotopes are leguminous cultivations and fallows with extensive pastures. Grazing can have either a positive or a negative effect on these fields, depending on cattle density. Besides the number of small dams, drinking places are still a limiting factor for this species. Dispersion of settlements and roads is also negative to sandgrouse distribution.

Grazing can have either a positive or a negative effect on these fields, depending on cattle density. Besides the number of small dams, drinking places are still a limiting factor for this species. Dispersion of settlements and roads is also negative to sandgrouse distribution. Finally conservation implications, namely management actions such as an enlargement of leguminous fields, cattle grazing control and modifications of Territory Management Plans, are discussed.</style></abstract><issue><style face="normal" font="default" size="100%">2</style></issue><notes><style face="normal" font="default" size="100%">The following values have no corresponding Zotero field:&lt;br/&gt;pub-location: MELQUIADAS BIENCINTO 34, E-28053 MADRID, SPAIN&lt;br/&gt;publisher: SOC ESPANOLA ORNITOLGIA</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%">Lombardi, Ludgarda</style></author><author><style face="normal" font="default" size="100%">Fernández, Néstor</style></author><author><style face="normal" font="default" size="100%">Moreno, Sacramento</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Habitat use and spatial behaviour in the European rabbit in three Mediterranean environments</style></title><secondary-title><style face="normal" font="default" size="100%">Basic and Applied Ecology</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Doñana National Park</style></keyword><keyword><style  face="normal" font="default" size="100%">Food quality</style></keyword><keyword><style  face="normal" font="default" size="100%">habitat selection</style></keyword><keyword><style  face="normal" font="default" size="100%">Home range size</style></keyword><keyword><style  face="normal" font="default" size="100%">Mediterranean ecosystems</style></keyword><keyword><style  face="normal" font="default" size="100%">oryctolagus cuniculus</style></keyword><keyword><style  face="normal" font="default" size="100%">predation risk</style></keyword><keyword><style  face="normal" font="default" size="100%">Prey behaviour</style></keyword><keyword><style  face="normal" font="default" size="100%">Resource availability</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2007</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2007///</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://linkinghub.elsevier.com/retrieve/pii/S1439179106000880</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">8</style></volume><pages><style face="normal" font="default" size="100%">453 - 463</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">The abundance and behaviour of mammalian prey species such as the European rabbit (Oryctolagus cuniculus) are known to be regulated by the availability of both food for maintenance and reproduction and shelter for protection against predators and harsh weather. However, the effect of vegetation structure and temporal variations in food availability on habitat selection and spatial behaviour are still poorly understood. The present study investigated the relationship between rabbit spatial ecology and vegetation structure and food quality and quantity in three neighbouring areas in SW Spain that differed in the distribution and amount of refuge sites and food patches. In all, 35 rabbits were radiotracked in the three study areas and home range and core area sizes in different seasons and at different times of the day estimated. Spatial behaviour was then compared with parameters of vegetation cover and food quantity and quality. Lastly, rabbit habitat selection at two levels was studied: home range selection and selection within home ranges. Home range size varied from one study area and season to another, but was not dependent on either sex or the availability or quality of food. We suggest that differences in home range size between study areas respond to differences in vegetation cover, with smaller home ranges in areas with higher proportion of sheltering vegetation. It was found that habitat selection patterns varied between the three areas in terms of the need for rabbits to exploit to a maximum the scarcest resource in each situation, thereby optimising access to both feeding and refuge patches. This pattern was manifest at the home range level of habitat selection but not at the level of selection within home ranges. Findings were consistent with the high behavioural plasticity of the European rabbit in its native habitats and provide useful information for habitat management.</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%">Franco, a M. a</style></author><author><style face="normal" font="default" size="100%">Catry, I.</style></author><author><style face="normal" font="default" size="100%">Sutherland, W.

This supports the view that habitat constraints limit numbers and distribution of this Palaearctic species at the southern edge of its range.</style></abstract><notes><style face="normal" font="default" size="100%">doi: 10.1139/z98-065</style></notes><research-notes><style face="normal" font="default" size="100%">doi: 10.1139/z98-065</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%">Tellería, J L</style></author><author><style face="normal" font="default" size="100%">Santos, T</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Effects of forest fragmentation on a guild of wintering passerines: the role of habitat selection</style></title><secondary-title><style face="normal" font="default" size="100%">Biological conservation</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Forest fragmentation</style></keyword><keyword><style  face="normal" font="default" size="100%">habitat selection</style></keyword><keyword><style  face="normal" font="default" size="100%">Spain</style></keyword><keyword><style  face="normal" font="default" size="100%">wintering passerines</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">1995</style></year></dates><volume><style face="normal" font="default" size="100%">71</style></volume><pages><style face="normal" font="default" size="100%">61-67</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">This study analyses the winter colonization of an archipelago of 31 forests (0.1-350 ha) in central Spain by the guild of pariforms (Parus, Aegithalos, Regulus, Sitta and Certhia). Two hypotheses are considered: (a) that birds with similar habitat preferences tend to disap- pear simultaneously with the reduction in forest size, leading to a ‘nested’ pattern of species distribution; or (6) that the species in the smallest forests are a random sample of those found in the larger ones. The results sup- port hypothesis (a). The species that depend on rela- tively scarce resources, such as tree trunks and junipers Juniperus thurifera (Sitta europaea, Certhia brachy- dactyla, Parus cristatus and P.ater) only occupied the largest forests. On the other hand, species that exploit abundant, ubiquitous resources, such as holm oak Quercus ilex foIiage (Regulus ignicapillus and Parus caeruleus), were distributed uniformly throughout all the fragments. These results emphasize the need for a better understand- ing of habitat selection by species when designing conser- vation strategies for fragmented populations.</style></abstract></record></records></xml>
