Genetic population structure of the masked palm civet Paguma larvata , (Carnivora: Viverridae) in Japan, revealed from analysis of newly identified compound microsatellites

摘要: The masked palm civet Paguma larvata (Carnivora: Viverridae) in Japan has been phylogeographically considered an introduced species from Taiwan. To reveal the population structures and relationships among P. populations Japan, seven compound microsatellite loci were isolated genome genotyped for 287 individuals collected field. STRUCTURE analysis factorial correspondence of genotyping data revealed that animals divided into four genetic clusters. Geographic distribution clusters partly referred to sampling areas, indicating multiple introductions distinct areas or independent founding events leading generation different within Japan. large differentiation Shikoku District those other suggests there at least two introduction routes a possibility some founders than Taiwan also involved variation Japanese not markedly reduced compared with results indicated could have retained moderate diversity during events, because introductions, number high founders. Although showed sign admixture between clusters, is no evidence such increased populations.
