Abstract:

Derby eland (Taurotragus derbianus) occurs in two lineages, usually recognized as subspecies, Eastern Giant eland (T. d. gigas) and Western Derby eland (T. d. derbianus). Eastern subspecies is currently listed as Least Concern (LC) and population seem to be stable. Nevertheless, the western subspecies is claimed as Critically Endangered. We assessed 11 new polymorphic microsatellite markers and presented their usage in particular population genetic analyses. Using this panel, it was possible to categorize each individual according to its origin into respective population. Despite low genetic variance, internal structure of Western Derby eland was detected, probably correlating with maternal lineages. It was confirmed that inbreeding coefficient is increasing with each generation in captive population of Western Derby eland. Comparison of last generation of Western Derby eland and populations from the Zoological gardens provided evidence of strong effect of genetic drift. Each of these populations is also highly influenced by founder effect. Our results confirmed the potential of genetic approach, which is essential for effective long term conservation and management. We also tried to estimate mothers of several individuals where the information was missing in the pedigree.
