极地鱼在历史保护区的繁殖速度比捕鯨者容易进入的地方要快. Arctic bowhead whale populations rebound faster in historically protected areas than in regions where whalers had easy access.

研究人员发现,在几个世纪前海冰阻碍捕者进入的地区, 长头种群正在迅速恢复. Researchers found bowhead whale populations are recovering faster in areas where historic sea ice kept whalers away centuries ago. 虽然阿拉斯加和西格陵兰的鱼类在这些保护区上有所回升, 但东格陵蘭及俄霍茨克海等地区的种群仍然很少, 因为捕者容易进入这些区域. While stocks off Alaska and West Greenland rebounded due to these protected zones, populations in regions like East Greenland and the Sea of Okhotsk remain depleted because whalers easily accessed those areas. 这项研究强调了过去的狩猎与冰层壁垒如何形成北极地区不均的恢复模式. The study highlights how past hunting combined with ice barriers shaped uneven recovery patterns across the Arctic.
