Abstract
DNA fingerprinting was used to estimate genetic diversity within the endangered Siberian crane (Grus leucogeranus) captive population consisting of several dozens of founders originating from the two wild populations of eastern and western Siberia. Similarity and difference among captive individuals were demonstrated by the unweighted pair‐group (UPGMA) clustering procedure. Quantitative characteristics of the eastern and western captive population groups such as average percentage differences (APD) and heterozygosity showed a high extent of genetic variability of 77.9–79.3% and heterozygosity of 0.85–0.72 within each group. Genetic heterogeneity of the captive population structure observed here provides guidelines for management of the species gene pool in captivity. These data also indicate that monitoring of genetic diversity through DNA fingerprinting can facilitate the efforts of Siberian crane management and restoration.
