Abstract

Abstract. The sika deer population on Yakushima Island exhibits high genetic diversity despite the small size of the island. We hypothesized that the high genetic diversity of the population had been maintained by the population structure, which included several subpopulations among which gene flow was limited. To test this hypothesis, we analyzed the spatial genetic structure of the population using 12 microsatellite loci. Two and four subpopulations were detected by STRUCTURE (stN and stS) and GENELAND (glN, glE, glS, and glW) software, respectively. The basic genetic structure assigned by STRUCTURE was supported by GENELAND, while stN and stS were further separated into two subpopulations (glN and glE; glS and glW, respectively) by GENELAND. All pairwise genetic differentiations between the two and four subpopulations were significant. These results demonstrated that the Yakushima population was structured into genetically distinct subpopulations. Although the location of the western boundary between stN and stS corresponded with a large river, no landscape or biological feature could be identified for the eastern boundary. We discussed the relationships between the genetic structure and management units designed by the local government and concluded that the Yakushima population should be managed based on their spatial population structures considering multiple time scales.
屋久岛梅花鹿种群的空间遗传结构:一个小岛上显著的遗传分化
摘要屋久岛上的梅花鹿种群尽管面积很小,但遗传多样性很高。我们假设种群结构保持了种群的高度遗传多样性,其中包括几个基因流动有限的亚群。为了验证这一假设,我们使用12个微卫星位点分析了群体的空间遗传结构。STRUCTURE(stN和stS)和GENELAND(glN、glE、glS和glW)软件分别检测到两个和四个亚群。structure分配的基本遗传结构得到了GENELAND的支持,而stN和stS被GENELAND进一步分离为两个亚群(分别为glN和glE;glS和glW)。两个和四个亚群之间的所有成对遗传差异都是显著的。这些结果表明,屋久岛种群被构造成遗传上不同的亚群。尽管stN和stS之间的西部边界的位置与一条大河相对应,但无法确定东部边界的景观或生物特征。我们讨论了遗传结构与地方政府设计的管理单位之间的关系,得出结论:屋久岛种群应根据其空间种群结构进行管理,并考虑多个时间尺度。
