在新西兰结束商业捕鲸活动五十年后,座头鲸种群正在恢复,研究表明,老年男性在育种中日益占优势,这是健康人口动态的标志。 Fifty years after New Zealand ended commercial whaling, humpback whale populations are recovering, with research showing older males becoming more dominant in breeding—a sign of healthier population dynamics. 在2000年代到2010年代的数据中观察到的这一转变表明,在数十年的过度狩猎下降之后,自然生殖模式又回到了自然生育模式。 This shift, observed in data from the 2000s to 2010s, indicates a return to natural reproductive patterns after decades of decline from overhunting. 虽然新西兰现在主张保护鲸鱼,但批评者警告说,南太平洋正在进行的底拖网捕捞威胁到海洋生态系统。 While New Zealand now advocates for whale conservation, critics warn that ongoing bottom trawling in the South Pacific threatens marine ecosystems. 科学家强调,需要继续监测以跟踪恢复和生态变化情况。 Scientists stress the need for continued monitoring to track recovery and ecological changes.
