Biotic responses to large-scale climate processes are scale-dependant and can influence population trajectories of highly migratory species such as short-tailed shearwaters Ardenna tenuirostris. In this study, we quantified changes in climate, measured through large-scale climate indices (i.e. Northern Pacific Index, Pacific Decadal Oscillation, El Niño–Southern Oscillation and Southern Annular Mode) and local weather conditions (i.e. rainfall) on the breeding performance of short-tailed shearwaters at four of their breeding colonies within the Furneaux Island Group, Tasmania, Australia, from 2010 to 2018. There was inter-colony variability in adult body mass and breeding participation, which were influenced by climate conditions in the preceding year. In contrast, breeding success was influenced by climate conditions in the preceding three to four months and by local weather conditions at the time of breeding. These findings demonstrate that variation in the breeding performance of short-tailed shearwaters are explained both by large-scale climate indices and local environmental conditions. The outcomes of this study provide a better understanding of the environmental factors affecting short-tailed shearwaters.

对大规模气候过程的生物响应取决于规模，并且可以影响高度迁徙物种（例如短尾剪水Ardenna tenuirostris）的种群轨迹。在这项研究中，我们通过大规模的气候指数（即北太平洋指数，太平洋年代际涛动，厄尔尼诺-南方涛动和南方环状模式）和当地天气状况（即降雨）对气候变化的量化来量化。从2010年到2018年，澳大利亚塔斯马尼亚岛Furneaux岛群内四个繁殖地的短尾shear水。成年体重和繁殖参与的菌落间存在变异，这受前一年的气候条件影响。相反，育种成功与否取决于前三到四个月的气候条件以及育种时的当地天气条件。这些发现表明，短尾shear水繁殖性能的变化可通过大规模气候指数和当地环境条件来解释。这项研究的结果更好地了解了影响短尾剪力水的环境因素。
