Abstract

The Spitsbergen population of bowhead whales (Balaena mysticetus) was harvested to near extinction during the whaling era. Here, we show possible signs of recovery of the population by reporting observations of two calves in the Scoresby Sund polynya in East Greenland on 2 and 4 May 2022, and it is the first observation of this kind in this area since the early 1900s.

濒临灭绝的斯匹次卑尔根弓头鲸可能恢复的迹象:在格陵兰岛东部观察到的幼鲸
在捕鲸时代,斯匹次卑尔根岛的弓头鲸(Balaena mysticetus)种群被捕捞到几乎灭绝。在这里,我们通过报告2022年5月2日和4日在东格陵兰岛的Scoresby Sund polynya观察到的两只幼崽,显示了种群恢复的可能迹象,这是自20世纪初以来在该地区首次观察到这种情况。

期刊介绍: Since 1982, Polar Research has been the international, peer-reviewed journal of the Norwegian Polar Institute, Norway''s central institution for research, environmental monitoring and mapping of the polar regions. Aiming to promote the exchange of scientific knowledge about the Arctic and Antarctic across disciplinary boundaries, Polar Research serves an international community of researchers and managers. As an open-access journal, Polar Research makes its contents freely available to the general public. Original primary research papers comprise the mainstay of Polar Research. Review articles, brief research notes, letters to the editor and book reviews are also included. Special issues are published from time to time. The scope of Polar Research encompasses research in all scientific disciplines relevant to the polar regions. These include, but are not limited to, the subfields of biology, ecology, geology, oceanography, glaciology and atmospheric science. Submissions from the social sciences and those focusing on polar management and policy issues are welcome. Contributions about Antarctica are particularly encouraged.
