摘要: 在全球生物多样性面临威胁的背景下, 保护野生动物的遗传多样性对于维护生态平衡和提升生态系统适应能力具有至关重要的作用。本研究以艾比湖保护区马鹿为研究对象, 采用非损伤性取样法获取粪便样本, 基于微卫星和线粒体标记(CYTBD-LOOP)分析其遗传多样性和遗传结构。结果显示, 微卫星整体观测杂合度(Ho)为0.662, 期望杂合度(He)为0.777, 多态信息含量(PIC)为0.712, 近交系数(Fis)为0.165, 整体偏离哈迪-温伯格平衡; 线粒体标记CYTB及D-LOOP单倍型多样性(Hd)分别为0.447和0.605, 核苷酸多样性(Pi)分别为0.00463和0.00334, 与其他马鹿亚种相比艾比湖保护区马鹿的遗传多样性处于中等偏高水平, 未发生瓶颈效应且存在一定程度的近交现象。微卫星Structure分析、主坐标分析表明, 艾比湖保护区马鹿分为两个聚类群体, 推测其发生了遗传分化。系统发育及遗传距离表明, 艾比湖保护区马鹿与天山马鹿及阿勒泰马鹿亲缘关系较近。作为保护区内的大型有蹄类物种之一, 其遗传多样性对维持生态系统具有重要意义。因此, 为维持保护艾比湖保护区马鹿遗传多样性, 建议加强马鹿栖息地的保护, 构建生态廊道以促进基因交流, 避免发生近交现象。

Abstract

Aims: In the context of global biodiversity facing threats, protecting the genetic diversity of wildlife is of critical importance for maintaining ecological balance and enhancing the adaptive capacity of ecosystems. 

Methods: This study took red deer in the Ebinur Lake Nature Reserve as the research object, using non-invasive sampling methods to collect fecal samples, and analyzed their genetic diversity and genetic structure based on microsatellite and mitochondrial markers (CYTB, D-LOOP). 

Results: The results showed that the overall observed heterozygosity (Ho) for microsatellites was 0.662, the expected heterozygosity (He) was 0.777, the polymorphic information content (PIC) was 0.712, and the inbreeding coefficient (Fis) was 0.165, indicating a deviation from Hardy-Weinberg equilibrium. The haplotype diversity (Hd) of mitochondrial markers CYTB and D-LOOP was 0.447 and 0.605, respectively, and the nucleotide diversity (Pi) was 0.00463 and 0.00334, respectively. Compared to other subspecies of red deer, the genetic diversity of red deer in Ebinur Lake National Park is moderately high. No bottleneck effect has occurred, and a certain degree of inbreeding is present. Microsatellite structure analysis and principal coordinate analysis indicate that red deer in Ebinur Lake Nature Reserve form two distinct clusters, suggesting genetic differentiation has occurred.Phylogenetic and genetic distance analysis suggests that the red deer in the Ebinur Lake Nature Reserve are closely related to the Tianshan red deer and the Altai red deer. 

Conclusion: As one of the large ungulate species within the reserve, its genetic diversity is of significant importance for maintaining the ecosystem. Therefore, to preserve the genetic diversity of the red deer in the Ebinur Lake Nature Reserve, it is recommended to strengthen the protection of red deer habitats, establish ecological corridors to facilitate gene exchange, and prevent inbreeding.
