| Abstract |
|
Testudinidae Microsatellite DNA was used to investigate levels of genetic variability in severely fragmented populations of the geometric tortoise, Psammobates geometricus, the most endangered tortoise on mainland Africa. Eight microsatellite markers were used to assess genetic variability within and between three naturally occurring populations of P. geometricus. These populations are separated by the Cape Fold mountain ranges in the western Cape region of South Africa. Levels of variability were quantified using allelic diversity, genotypic frequencies and heterozygosity. Evidence for population sub-structuring was examined using F statistics, Rst and dµ2. High levels of variability were found in all three populations. Low levels of population differentiation were found suggesting significant gene flow between the populations.
