Genetic Variation Among Populations of Eurycea Tynerensis and Neotenic Eurycea Multiplicata Griseogaster
Date of Graduation
Master of Science in Biology
Electrophoresis was used to compare two morphologically similar species of Eurycea, Eurycea tynerensis and neotentic Eurycea multiplicata griseogaster. Enzymatic proteins encoded by fourteen loci were examined. Heterozygosity values were low, while FST values were high. Cluster analysis using Nei's identity values failed to group all populations as expected. Various methods of identification proved highly contradictory when used on specimens in this study. It is recommended that neotenic salamanders with 18 or more costal grooves in southwestern Missouri be considered one species.
