Amphibians After Disease‐Induced Declines: Genetic Insights Into Population Recoveries
Molecular Ecology, Volume 35, Issue 12, June 2026.ABSTRACT Infectious diseases can cause severe population declines, reducing genetic diversity, ecological function, and prospects for long‐term survival. Such declines often result in genetic bottlenecks, with small, isolated populations that are especially vulnerable to extinction due to genetic drift and inbreeding.
