Divergence among Populations of the Yellow-bellied Slider Turtle (Pseudemys
scripta) separated by Aquatic and Terrestrial Habitats
T. Scribner, J. E. Evans, S. J. Morreale, M. H. Smith and J. W. Gibbons
Allelic variations at 18 loci is described for Pseudemys
scripta (N=367) live-trapped from 12 populations, representing three
habitat types separated by different types of intervening habitat (terrestrial
vs aquatic). Of the 18 loci
examined, 13 were polymorphic. Mean
heterozygosity was 0.131. Significant
allele frequency differences were observed among the 12 populations.
Patterns of allelic differentiation and overall genetic divergence among
populations were not consistent across habitat types.
Populations from aquatically separated habitats had significantly higher
heterozygosities than did populations from terrestrially separated habitat and
showed less interpopulation genetic distance/unit distance. However, genetic similarities among populations appear to be
a function of geographic proximity, regardless of the intervening habitat and
potential for dispersal and interpopulation gene flow.
