Description
Genetic Population Structure of Two Frog Species Common to the Grand Valley State University Allendale Campus. Karel Rogers, Jessica Demeuse, Katie Smith, Stephen Burton, and Erin Davis, Grand Valley State University, Biology Department, Allendale, MI 49401-9403 To determine detailed population demographics and metapopulation characteristics, ninety frogs of two common species (Rana clamitans and R. pipiens) on the Grand Valley State University Allendale Campus were captured, sampled for field data, toe-clipped for skelerochronology and mtDNA samples, and released unharmed during summer, 2002. The field data have been entered into a data base that has been used to generate GIS views of frog distribution on the campus. mtDNA (12S and cytochrome b genes) has been amplified, purified, and sequenced from 72 toe-tip samples using custom primers. The 12S gene evolves slower than cytochrome b so cladistic analysis of the gene sequences are used to infer relatedness between individual frogs as well as relatedness between populations in different ponds. These studies are of importance because they will allow us to better understand the impacts of recent road work and site development on the genetics of these vulnerable wetland species.
