摘要

在动物生态学研究中，观察每年的繁殖周期是一项基础性的监测工作。在这项研究中，我们报道了在南极洲乔治王岛巴顿半岛对威德尔海豹（Leptonychotes weddellii）的七对母子的详细观察。2015年、2017年和2018年，在快冰沿岸观察到两三对，2016年没有繁殖记录。尽管个体之间有所不同，但据记录，幼崽出生于9月19日至25日，出生后第18日至19日开始游泳，第21日至25天蜕皮。我们的观测结果可能会为我们研究地点的威德尔海豹提供基本的繁殖信息，并为未来的海豹长期监测研究做出贡献。

Weddell seal observations on female and pup behavior and breeding status for four overwintering periods (2015 to 2018) at Barton Peninsula, King George Island, Antarctica

In animal ecology studies, it is a fundamental monitoring work to observe annual breeding cycle. In this study, we report the detailed observations on seven mother and pup pairs of Weddell seal ( Leptonychotes weddellii ) at Barton peninsula, King George Island, Antarctica. Two or three pairs had been observed along the coast on the fast ice in 2015, 2017, and 2018 and no breeding was recorded in 2016. Although it varied among individuals, pups were recorded to be born on 19−25 Sept., began swimming at day 18−19 after birth, and molted at day 21−25. Our observations may provide fundamental breeding information of Weddell seals in our study site and contribute to the future long-term monitoring research of seals.
