Abstract
Objective: The genetic diversity parameters for gazelle populations sampled in Turkey were estimated to assess the effects of captive breeding on the populations’ gene pools and effective population sizes. Materials and Methods: Four individuals from a recently discovered Gazella gazella population in Hatay and two captive gazelle populations were sampled (the Kızılkuyu State Farm (n=48) and the Erikçe State Farm (n=25)) and analyzed using nuclear DNA, mtDNA and Y-chromosome markers. Results: The mtDNA cyt-b partial sequence analysis assigned the Erikçe and Kızılkuyu samples to Gazella marica. The structure analysis differentiated significantly between them, and revealed samples originating from wild population. Both, the Y-chromosome INRA126 locus sequences of Gazella gazella and Gazella marica males and the mtDNA partial cyt-b region RFLP analysis from all the samples distinguished the two gazelle species from each other. Based on microsatellites, the estimated effective population sizes were 9.7, 8.9 and 6.4 for the Kızılkuyu, Erikçe and Hatay populations, respectively. When the Kızılkuyu and Erikçe populations (where severe inbreeding depressions seems to be occurring already) were pooled, the estimated Ne was 24.5. All these estimates were too small for the sustainability of either individual or pooled populations in the wild or even in captivity. Conclusion: The markers used in the study provided information on two of the gazelle species (Gazella marica, and Gazella gazella): their species identity, degree of divergences, effective population sizes and the presence of admixture within the populations. These results turned out to be invaluable in terms of their contribution to future studies for the conservation of these species.
