“…Several antelope taxa, among them eland ( Taurotragus oryx Pallas, 1766), vulnerable and endangered Gazella and Procapra species and the critically endangered saiga antelope ( Saiga tatarica Linnaeus, 1766), yielded similarly high or even higher values of mtDNA diversity (Lorenzen et al. 2010; Zachos et al. 2010a and references therein).…”

We analysed 131 common impala (Aepyceros melampus melampus) samples from two provinces in South Africa (Limpopo and KwaZulu-Natal) that are separated by the Drakensberg Mountain Range using sequences of the mitochondrial control region and seven polymorphic nuclear microsatellite loci. In line with earlier studies on bovid species, we found very high values of genetic diversity, particularly at the mtDNA locus with an overall nucleotide diversity of 3.6% and an overall haplotype diversity of 0.98. All statistical approaches confirmed a significant population differentiation between Limpopo and KwaZulu-Natal, suggesting that areas of unsuitable habitat caused by the presence of the Drakensberg Range and the Indian Ocean coastal belt act as a barrier to gene flow. Only few individuals with signs of admixed origin were indicative of translocations or rare migration between the two provinces. Combination of our mtDNA data set with those of previous studies on impala from south-western, southern and eastern Africa revealed the highest diversity in South Africa. This is in line with the hypothesis of a southern glacial refuge from which various African ungulate species spread northeast during the Holocene, although in the case of impala further analyses based on larger data sets will be necessary to definitively settle this question.

“…However, when compared with genetic variation of other wild gazelles using the least biased estimator (H E ), such as Grant's gazelle (0.61, Arctander et al 1996), Chiru (0.84, Zhou et al 2007) and goitered gazelle (0.72, Zachos et al 2010), the nuclear genetic diversity of Przewalski's gazelle is relatively low. Previous genetic study on Przewalski's gazelle using mtDNA also found that the nucleotide diversity (\0.004) of Przewalski's gazelle is lower than most mammals (Lei et al 2003a).…”

The Przewalski's gazelle (Procapra przewalskii) is one of the most endangered antelope species in the world. It is endemic to China and is a flagship species in the eastern part of the Qinghai-Tibet plateau. To establish effective conservation measures on this species, genetic information such as genetic structure is needed. However, there has not been a comprehensive genetic assessment on this gazelle using nuclear DNA markers yet. Here, we employed 13 microsatellite loci to investigate genetic diversity, population genetic structure and demographic history of Przewalski's gazelle using noninvasive samples of 169 wild gazelles collected from nine populations. A total of 76 alleles were detected from the entire samples, mean allele number was 5.85, and overall H O and H E were 0.525 and 0.552, respectively. Structure and GENELAND analyses found six genetic groups in the nine populations. Between the inferred genetic groups, significant genetic differentiation and low migration rates were detected. Demographic analyses indicated that Przewalski's gazelle experienced genetic bottleneck and severe population decline, with the ancestral effective population size reducing to less than one percent. Based on the results of this study, we provide several conservation recommendations for Przewalski's gazelle, such as six management units, periodic monitoring and special conservation consideration on the Qiejitan population.

We analysed 229 Eurasian otters from eastern and north-western Germany, Denmark and southern Sweden based on sequences of the mtDNA control region and genotypes at 12 polymorphic nuclear microsatellite loci. The main focus of the study lay on the north-west German otters from Schleswig-Holstein, which represent a newly established and expanding population recolonizing a formerly inhabited region, thereby closing the distributional gap between the large eastern population and the long-isolated and genetically depleted Danish population. As found before in this species, mtDNA variability was very low but we identified a hitherto unknown haplotype in Sweden. Expected heterozygosities were between 0.46 and 0.69 and thus within the range known from the literature. There were only weak signs of a founder effect in the Schleswig-Holstein otters with respect to allelic diversity (but not heterozygosity). Nevertheless, there was a statistically significant bottleneck signal based on deviations from mutation-drift equilibrium in Schleswig-Holstein. All statistical approaches (amovas, factorial correspondence analysis, assignment tests and Bayesian structure analysis) unequivocally showed that north-western Germany has so far been predominantly recolonized by otters of east German origin, but we also found evidence of admixture through immigration from Denmark. Both the Danish and the north-west German otter population will benefit from further exchange in the wake of the ongoing range expansion.
