Abstract:
Numbers of golden eagles (Aquila chrysaetos) were severely reduced by hunting towards the end of the last century over large parts of central Europe. To estimate the genetic variation in a currently thriving golden eagle population from the Swiss Alps, organ samples of 15 carcasses, collected during 1975-1993, were used for electrophoretic analysis of 31 isozyme systems encoding for 37 putative structural gene loci. Average heterozygosity (H-e = 3.4%) was within the range found in various other bird taxa, despite a probably low "effective population size" of this population early in this century. Nevertheless, the somewhat reduced rate of polymorphism (P-99% = 10.8) and the mean number of alleles (A = 1.11) may indicate reduced genetic variability, although the H:P ratio was within the range of many non-endangered avian species.
