摘要: Abstract Fenced roads fragment terrestrial vertebrate populations, the individuals of which are forced to cross these infrastructures using transverse structures inherent road’s construction (culverts, over- and underpasses) or other specially adapted constructed for use by fauna (enlarged culverts bridges, ecoducts). The information available on different crossing structure types vertebrates, role played structural variables, surroundings human passages is still scarce. 82 A-52 motorway (Zamora, North-western Spain) vertebrates was monitored in summer 2002 marble dust beds electronic cameras. A total 1122 species track-days were recorded, with an average 1.37 −1 day . results showed that aspects most determining factors (MANCOVA test, p
