ENVIRONMENTAL FACTORS INFLUENCING AMPHIBIAN COMMUNITY ASSEMBLAGE IN DUNE WETLANDS ON THE LAKE MICHIGAN COAST
Amphibian conservation has become increasingly important in recent years due to worldwide declines in amphibian biodiversity. Many amphibians utilize wetlands for habitat and breeding purposes, but current legislation limits wetland protection greatly, leaving many of these habitats unprotected. We analyzed amphibian species richness and environmental variables in 16 permanent and ephemeral wetlands along the coast of Lake Michigan in Grand Haven, MI from April to September of 2017.
Nine species of amphibian were found: Green Frogs and Spring Peepers were most abundant; and Fowlers Toad was rarest. Wetlands in open dunes had significantly different species assemblages than those in forested habitat. Richness did not differ significantly between habitat types. Isolation score was significantly negatively correlated with species richness. Hydroperiod, area and depth were significantly positively correlated. Species richness was significantly positively correlated with hydroperiod and area. However, some small temporary wetlands situated in the open dunes harbored rare species not found in other wetlands. These findings highlight the importance of protecting all of these habitats from land development, fragmentation and degradation in order to conserve multiple species, as well as overall landscape connectivity of the system.
