Small-scale alterations in carnivore activity patterns close to motorways

摘要: The effects of roads on the fauna their surroundings, negative ones for most species, have been widely studied over recent decades. Nevertheless, little is known changes in activity patterns carnivores near roads, which determine what impacts that they may experience. An intensive 2-year study carnivore community around a 5-km stretch Spanish motorway has carried out order to clarify this situation. at three distances from (0, 500 and 1000 m) were assessed by means complementary sampling methods (scat transects, hair traps camera traps) both whole-community analyses (redundancy analysis) species-specific (generalised linear mixed models, occupancy models). results show an intense use proximities community, with road possibly acting as artificial home-range boundary, well differential interspecies responses presence infrastructure. Thus, foxes, stone martens, weasels genets made more vicinity whereas badgers cats indifferent or slightly favoured distant zones. Knowledge alteration important understanding direct (e.g. roadkills) indirect predation cascades) trigger ecosystems, it relevant implications design effectiveness mitigation measures.
