Abstract

Genetic founder effects of a historical translocation (1965; app. 12 generations ago) of endangered softmouth trout from the only remaining indigenous population to an adjacent uninhabited river were investigated.

A comparison of 15 microsatellites from contemporary samples in both the source and re-established populations indicated a very low level of genetic diversity within the two populations. Furthermore, considerable differences in estimates of variability and effective population sizes were detected between populations, but no recent bottlenecks were evident. Our data suggest that the re-established population has lost variation due to genetic drift associated with founder effects following the translocation. Accordingly, in relation to management, we suggest that the re-established population could serve as a secondary source of individuals to buffer possible extinction due to demographic events. Finally, conservation initiatives to enhance the census population size and increase levels of variability in the re-established population are proposed.
