USE OF BREEDING SITES BY ARID-LAND TOADS IN RANGELANDS: LANDSCAPE-LEVEL FACTORS

We examined spatial extent of habitat that anaxyrids responded to in an arid environment. We used surveys of vocalizations and searches to identify toads after rainfall events to examine whether the spatial arrangement and proximity of earthen tanks could influence breeding populations of Anaxyrus cognatus and A. These species responded to the landscape complement of breeding sites inside a buffer of 5 km, a much larger distance than most studies have addressed.
