Combined impacts of longline fisheries and climate on the persistence of the Amsterdam Albatross Diomedia amsterdamensis
Incidental capture of seabirds in longline fishing gear is a central issue in the conservation of many long‐lived marine species. Despite growing evidence of climate‐induced effects on population trends of long‐lived species, climate change remains generally overlooked in most risk assessments of se...

Incidental capture of seabirds in longline fishing gear is a central issue in the conservation of many long‐lived marine species. Despite growing evidence of climate‐induced effects on population trends of long‐lived species, climate change remains generally overlooked in most risk assessments of seabirds. Because variation in climate may interact with the detrimental effects of bycatch, considering climate is of great importance, especially in the context of ongoing global warming. This paper examines the combined effects of bycatch and climate change on the persistence of one of the world’s rarest birds, the Amsterdam Albatross Diomedea amsterdamensis , which has a single population in the upland plateau of Amsterdam Island (Southeast Indian Ocean). Using continuous monitoring from 1983 onwards, we first estimated the relationship between climate and the species’ demographic parameters.
