The Importance of Environmental Heterogeneity in Evaluating the Conservation Status of Two Frog Species in a Changing Amazonian Interfluve

open access: yesAnimal Conservation, Volume 29, Issue 1, Page 60-70, February 2026.
Identifying the most effective criterion to assess the conservation status of vulnerable species in threatened tropical regions is crucial to evaluate recovery plans. We investigated the influence of environmental heterogeneity on the extent of occurrence (EOO), area of occupied habitat (AOH), and density variation of two Amazonian riparian frog ...
