Multi-Scale Approach to Understanding Source-Sink Dynamics of Amphibians

Abstract

The objective of this study was to improve our understanding of source-sink dynamics for subpopulations or populations of species of relevance to Department of Defense resource managers. Specifically, this project sought to better understand the impact of landscape heterogeneity on the source-sink dynamics of a species of conservation concern (the ringed salamander, Ambystoma annulatum) and a co-occurring species (the spotted salamander, A. maculatum) at Fort Leonard Wood, Missouri. Investigators sought to (1) define source habitat patches by identifying key environmental conditions associated with varying levels of reproductive success of A. annulatum, (2) determine whether species interactions influence source-sink dynamics, (3) identify habitat features associated with effective dispersal of A. annulatum among populations to define habitat connectivity, and (4) develop models to predict and manage population connectivity for salamanders in heterogeneous landscapes.
