摘要

蟹脚海豹(Lobodon carcinophaga)是最常见的南极海豹,但对其遗传方面的研究仍然不足。这项研究考察了南极半岛丹科海岸种群的遗传多样性和种群动态,并将其与南极洲西部种群进行了比较。研究发现了 20 个新的单倍型,揭示了一个稳定的种群阶段和一个短暂的扩展阶段。遗传多样性很高,与类似物种和环境中的遗传多样性一致。历史种群动态与更新世气候变迁相关,揭示了气候变化对南极生态系统的影响。这项研究增加了我们对南极海豹物种的了解,有助于该地区改进南极环境保护政策的指导方针。

Genetic Diversity and Population Dynamics of Lobodon carcinophaga in Danco Coast, Antarctica

The crabeater seal (Lobodon carcinophaga) is the most common Antarctic seal; however, it remains understudied regarding genetic aspects. This research examined the genetic diversity and population dynamics of the Danco Coast population in the Antarctic Peninsula and compared it with the Western Antarctica population. Twenty novel haplotypes were identified, revealing a stable population phase and a brief expansion. The high genetic diversity aligns with those found in similar species and environments. Historical population dynamics correlate with Pleistocene climate shifts, shedding light on climate change's impact on Antarctic ecosystems. This study increases our understanding of Antarctic seal species, contributing to the region's guidelines to improve environmental conservation policies in the Antarctic sector.

期刊介绍: Aquatic Conservation: Marine and Freshwater Ecosystems is an international journal dedicated to publishing original papers that relate specifically to freshwater, brackish or marine habitats and encouraging work that spans these ecosystems. This journal provides a forum in which all aspects of the conservation of aquatic biological resources can be presented and discussed, enabling greater cooperation and efficiency in solving problems in aquatic resource conservation.
