Natural landscape heterogeneity and barriers resulting from urbanization can reduce
genetic connectivity between populations. The evolutionary, demographic, and ecological …

Urban expansion is creating environmental stressors through land use change, habitat
fragmentation, and habitat loss. These stressors, along with a host of others, are driving …

Context Amphibian metapopulations have become increasingly fragmented in the
Midwestern United States, with wetland-breeding salamanders being especially dependent …

Many organisms are primarily constrained to the channels of the upstream terminus of river
networks with limited capacities for both in‐stream and overland dispersal. Dispersal is …

The network architecture of streams and rivers constrains evolutionary, demographic and
ecological processes of freshwater organisms. This consistent architecture also makes …

Understanding the impacts of landscape‐level processes on the population biology of
amphibians is critical, especially for species inhabiting anthropogenically modified …

Fragmented landscapes resulting from anthropogenic habitat modification can have
significant impacts on dispersal, gene flow, and persistence of wildlife populations …

Urbanization is a major cause of amphibian decline. Stream-dwelling plethodontid
salamanders are particularly susceptible to urbanization due to declining water quality and …

Population structure and gene flow of species in lotic environments can be constrained by
river network architecture, species life history and heterogeneous local barriers. Identifying …

Comparative landscape genetic studies provide insights into whether relationships between
landscape features and patterns of spatial genetic structure differ among populations …
