Multiscale Occupancy Patterns of Anurans in Prairie Wetlands

摘要: Abstract: Habitat loss and degradation appear to be the primary drivers of amphibian declines. Given losses native prairie wetlands, it is essential understand habitat conditions that support species in remaining ecosystems. In this study, we combine wetland surveys, geographic information systems (GIS), hierarchical statistical modeling assess anuran occupancy relationships with landscape factors. We surveyed 141 wetlands repeated sampling for breeding activity (calling, eggs, tadpoles, metamorphs) Sheyenne National Grasslands—one largest contiguous prairies on North American continent. Overall observed evidence seven Grasslands. Species ubiquitous distributions (Boreal Chorus Frogs) or occurred infrequently (Canadian Toads Great Plains Toads) had little variance occupancy. However, Northern Leopard Frogs, Wood Gray T...
