Mitochondrial DNA was sequenced at the ND5, CYTb and control regions, revealing zero nucleotide diversity within our wild-sampled individuals. In contrast, genotyping at up to 12 autosomal microsatellite loci determined no deviation from Hardy–Weinberg equilibrium and no indication of inbreeding depression (F IS = 0.010). Based on phylogenetic analyses of the mtDNA sequences, alongside those from one individual from Taiwan, four spraint samples from northern Fujian, China (this study), and 11 published sequences, the Kinmen otter population is most genetically similar to a now-extinct population in Taiwan, and forms a monophyletic group with southern Chinese populations. These results may guide a framework for implementing Eurasian otter conservation programs in and around the Kinmen region. |
