Objective Our objective was to assess landscape connectivity between Natura 2000 sites in the biodiversity-rich western Mediterranean region. Methods We used the wood mouse as a focal species with short-range dispersal and obtained genetic data for 393 individuals uniformly distributed between two Natura 2000 sites in SW Portugal. We created a map of connectivity between the two sites that was based on a stack of analyses including reciprocal causal modeling and least-cost path modeling coupled with resistant kernel analysis. Results Wood mice in the study area were genetically diverse and connected by gene flow over a large area. We did not find evidence of major population subdivision in the study area. Gene flow was limited by geographic distance, with significant genetic similarity between individuals within 3 km of each other. Vegetation cover and land use explained more of the variation in genetic distance than geographic distance alone. In particular, agroforestry areas and transitional woodland were associated with higher costs to movement than forest or arable land uses. This result may have been influenced by the difficulty in classifying land use in the open montado. Conclusions The Natura 2000 sites we studied are well connected by multiple corridors for dispersal. Our analysis also highlighted the importance of the Serra de Graˆndola, part of the European Long Term Ecological Research Network but not yet included in Natura 2000.</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%">Ascensão, Fernando</style></author><author><style face="normal" font="default" size="100%">Clevenger, Anthony P.</style></author><author><style face="normal" font="default" size="100%">Grilo, Clara</style></author><author><style face="normal" font="default" size="100%">Filipe, Joel</style></author><author><style face="normal" font="default" size="100%">Santos-Reis, Margarida</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Highway verges as habitat providers for small mammals in agrosilvopastoral environments</style></title><secondary-title><style face="normal" font="default" size="100%">Biodiversity and Conservation</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Apodemus sylvaticus</style></keyword><keyword><style  face="normal" font="default" size="100%">Capture–mark–recapture</style></keyword><keyword><style  face="normal" font="default" size="100%">Crocidura russula</style></keyword><keyword><style  face="normal" font="default" size="100%">Iberia Peninsula</style></keyword><keyword><style  face="normal" font="default" size="100%">Mediterranean</style></keyword><keyword><style  face="normal" font="default" size="100%">Montado woodlands</style></keyword><keyword><style  face="normal" font="default" size="100%">Mus spretus</style></keyword><keyword><style  face="normal" font="default" size="100%">Road ecology</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.springerlink.com/index/10.1007/s10531-012-0390-3http://link.springer.com/10.1007/s10531-012-0390-3</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">21</style></volume><pages><style face="normal" font="default" size="100%">3681 - 3697</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">The Mediterranean Basin has an important conservation value given its high biodiversity and high number of endemic species, which have co-existed with human traditional practices for centuries. However, northern areas as the Iberian Peninsula have experienced intensiﬁcation in livestock production in recent past, with consequent reduction in habitat quality. In this study we assessed the importance of fenced highway verges as habitat for small mammals in Mediterranean agrosilvopastoral landscapes. More speciﬁcally, we compared small mammal abundance between highway verges and the adjacent two main land uses (‘‘montado’’ and open areas); compared the vegetative structure among these land were captured: 157 wood mice (Apodemus sylvaticus), 95 western Mediterranean mice (Mus spretus) and 99 greater white-toothed shrews (Crocidura russula). Capture–mark– recapture analyses were performed to estimate population size. Our data suggests that fenced highway verges promote better vegetative structure conditions which in turn favor a higher animal abundance therein. We suggest the adoption of management practices to increase the height and cover of herbaceous and shrub layers in road verges, together with creating grazing controlled areas in highway vicinity, particularly in ‘‘montado’’ patches, linked by vegetated linear features. This would increase habitat and refuge for a large numbers of species, including small mammals, and thus beneﬁting the trophic chain and the whole agrosilvopastoral system. uses; and addressed how vegetation structure inﬂuences species occupancy. Thirty-six sites were sampled in agrosilvopastoral system areas in southern Portugal (sampling effort 8,840 trap-nights).

Previous studies have demonstrated that drainage culverts are used by vertebrates, although knowledge of the main inﬂuencing factors remains limited. The use of 34 culverts from two roads in southern Portugal, diﬀering in traﬃc volume, vehicle speeds and conﬁguration, was evaluated by the analysis of terrestrial vertebrate footprint data (408 passage-operative days). Culvert crossings were related to various explanatory variables by means of canonical ordination techniques. We recorded 901 complete crossings, corresponding to an average of 2.2 crossings/culvert/operative day. Thirteen taxa were detected, all in more than one passage. Animal species included reptiles, small mammals, lagomorphs, carnivores and domestic dogs and cats. Our results suggest that fencing might have a funnelling effect, directing larger animals toward culverts. Also, vegetation covering culvert entrances seems to have a positive eﬀect, particularly on genets; longer passages with entrances far from the pavement were, apparently, avoided by smaller animals; a lower number of crossings was detected on passages with detritus pits; the closest passages to urban areas are more often used by domestic species; forest-living species favour passages with low, open land cover nearby; and smaller species, like lagomorphs and small mammals, appear to use more culverts near the pavement, which probably reﬂects the importance of road verges as refuges for these species. Although not used by all species present in the study area, constructing numerous passages of diﬀerent sizes without detritus pits and which are distributed along roads might be an important step in mitigating road fragmentation eﬀects on animal populations.</style></abstract><label><style face="normal" font="default" size="100%">Incluir?</style></label></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%">Ascensão, Fernando</style></author><author><style face="normal" font="default" size="100%">Mira, António</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Factors affecting culvert use by vertebrates along two stretches of road in southern Portugal</style></title><secondary-title><style face="normal" font="default" size="100%">Ecological Research</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">canonical ordination</style></keyword><keyword><style  face="normal" font="default" size="100%">conservation</style></keyword><keyword><style  face="normal" font="default" size="100%">culvert use</style></keyword><keyword><style  face="normal" font="default" size="100%">Incluir?</style></keyword><keyword><style  face="normal" font="default" size="100%">Road ecology</style></keyword><keyword><style  face="normal" font="default" size="100%">Vertebrates</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://www.springerlink.com/index/10.1007/s11284-006-0004-1</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">22</style></volume><pages><style face="normal" font="default" size="100%">57 - 66</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">A major target for environmental managers when trying to minimise the road-barrier eﬀect on wildlife is to improve permeability to animal movements.
