Differentiation Among Local Populations of the Yellow-Bellied Slider Turtle (Pseudemys
T. Scribner, Michael H. Smith, and J. Whitfield Gibbons
Variation at 10 electrophoretic loci was used to
describe the population structure of yellow-bellied slider turtles (Pseudemys
scripta, n = 104) collected from four discrete locations on or near the
Savannah River Plant, Aiken, South Carolina.
Collectively, turtles exhibited a per locus heterozygosity of 0.148.
Enzyme polymorphisms were observed at seven of the 10 loci.
Significant spatial heterogeneity was observed at five of seven
polymorphic loci. Significant Fn
values were noted for 6-phosphogluconate dehydrogenase and phosphoglucomutase
seemingly due in part to presence or absence of rare alleles.
Neiís distance values between samples were consistently low, ranging
from 0.00-0.024. The disjunct
nature of suitable habitat could account for population genetic differentiation
as a result of drift or selection. However,
some gene flow as a consequence of terrestrial dispersal could account for
overall genetic similarities, particularly between variable environments.
