Abstract

Abstract. Native sika deer (Cervus nippon) had not been observed in and around Sasebo City, Nagasaki Prefecture, Kyushu, Japan. However, deer have recently been confirmed in this area, and the number of individuals and the range have been expanding, causing damage to forestry and natural vegetation. Although the origin of these deer is unknown, it may be derived from Formosan sika deer (C. n. taiouanus), which is listed as an invasive alien species in Japan. There is concern about hybridization between this subspecies and the native Japanese sika deer. In the present study, we used genetic methods to assess the current status of the deer in the Sasebo area of Nagasaki Prefecture, particularly its origin and hybridization. Our study showed that the deer did not originate from Formosan sika deer, and we found no evidence of hybridization. The deer in the Sasebo area were found to have a haplotype included in the southern Japanese sika deer lineage. The current study was unable to identify the specific origin of the deer due to limitations in PCR-RFLP and mitochondrial DNA sequencing analysis.

日本长崎县佐世保地区新建立的鹿种群的遗传分析没有发现台湾梅花鹿遗传干扰的证据
摘要在日本九州长崎县佐世保市及其周边地区未发现本地梅花鹿(Cervus nippon)。然而,鹿最近在这一地区被证实,个体数量和范围都在扩大,对森林和自然植被造成了破坏。虽然这些鹿的来源不明,但它可能来自台湾梅花鹿(c.n. taiouanus),这是日本列为外来入侵物种。人们担心这个亚种与日本本土梅花鹿之间的杂交。本研究采用遗传方法对长崎县佐世保地区小鹿的现状进行了分析,重点分析了其起源和杂交情况。我们的研究显示,梅花鹿并非起源于台湾梅花鹿,我们也没有发现杂交的证据。佐世保地区的鹿被发现具有日本南部梅花鹿谱系的单倍型。由于PCR-RFLP和线粒体DNA测序分析的限制,目前的研究无法确定鹿的具体起源。
