Climate change increases the frequency and intensity of extreme weather events that negatively impact wildlife, from individuals to whole ecosystems. In polar environments, such events include heat waves, anomalous sea ice concentrations and storms. Polar seabirds are adapted to withstand harsh conditions, and although extreme weather events affect their breeding success and other demographic rates, they are thought to affect only a part of the population. Complete breeding failure of an entire population due to extreme environmental conditions is rarely observed. Here we report how exceptional storm activity in Dronning Maud Land (DML), Antarctica, in the austral summer of 2021/2022 caused almost complete and large-scale breeding failures of the area's three most common seabird species - Antarctic petrel (Thalassoica antarctica), Snow petrel (Pagodroma nivea) and South polar skua (Stercorarius maccormicki).
气候变化增加了极端天气事件的频率和强度，这些事件会对野生动物产生负面影响，从个体到整个生态系统。在极地环境中，此类事件包括热浪、异常海冰浓度和风暴。极地海鸟适应了恶劣条件，尽管极端天气事件会影响它们的繁殖成功率和其他种群动态率，但人们认为这些事件只会影响一部分种群。由于极端环境条件导致整个种群完全繁殖失败的情况很少见。在此，我们报告了2021/2022年南半球夏季南极洲毛德皇后地（DML）异常的风暴活动如何导致该地区三种最常见海鸟——南极海燕（南极贼鸥）、南极雪海燕和南极贼鸥几乎完全且大规模的繁殖失败。
