Predictors of breeding site occupancy by amphibians in montane landscapes
Luke A. Groff, Cynthia S. Loftin, Aram J.K. Calhoun
2017, Journal of Wildlife Management (81) 269-278
Ecological relationships and processes vary across species’ geographic distributions, life stages and spatial, and temporal scales. Montane landscapes are characterized by low wetland densities, rugged topographies, and cold climates. Consequently, aquatic-dependent and low-vagility ectothermic species (e.g., pool-breeding amphibians) may exhibit unique ecological associations in montane landscapes. We evaluated the relative...
