Environmental Factors Influencing Amphibian Community Assemblage In Dune Wetlands On The Lake Michigan Coast, Alex H. Jouney

Masters Theses

Wetlands in dune landscapes provide important breeding habitat for amphibians along the Lake Michigan Coast. Unfortunately, these unique habitats and the corresponding amphibian metapopulations are understudied and threatened. We assessed amphibian species richness and terrestrial habitat type in 16 permanent and ephemeral wetlands along the coast of Lake Michigan in Grand Haven, MI. Wetland area, terrestrial habitat type, depth, hydroperiod, shade, and degree of isolation were measured from April to September of 2017. Nine species of amphibian were found; Green Frog (Rana clamitans melanota) and Spring Peepers (Pseudacris crucifer crucifer) were most abundant and Fowlers Toad …
