Demographic genetics of brown trout (Salmo trutta) and estimation of effective population size from temporal change of allele frequencies.

Abstract excerpt

We studied temporal allele frequency shifts over 15 years and estimated the genetically effective size of four natural populations of brown trout (Salmo trutta L.) on the basis of the variation at 14 polymorphic allozyme loci. The allele frequency differences between consecutive cohorts were significant in all four populations. There were no indications of natural selection, and we conclude that random genetic...
