Landscape‐Driven Isolation Among, but High Genetic Diversity Within, Peripheral Populations of a Threatened Frog

Diversity and Distributions, Volume 32, Issue 2, February 2026.
ABSTRACT Aim Many amphibians are experiencing declines, which are exacerbated for populations near range edges. To inform conservation strategies, we sampled sites of Blanchard's Cricket Frog (Acris blanchardi) at the northern periphery of their range to determine if modern declines are associated with genetic factors, delineate management units, and ...
