Demographic response of a population of white-chinned petrels Procellaria aequinoctialis to climate and longline fishery bycatch ArchiMer
Barbraud, Christophe; Marteau, Cedric; Ridoux, Vincent; Delord, Karine; Weimerskirch, Henri.
1. Fisheries can affect non-target species through bycatch, and climate change may act simultaneously on their population dynamics. Estimating the relative impact of fisheries and climate on non-target species remains a challenge for many populations because the spatio-temporal distribution of individuals remains poorly known and available demographic information is incomplete. <br>2. We used population survey data, capture-mark-recapture methods, population modelling and the demographic invariant method to investigate the effects of climate and fisheries on the demography of a predator species affected by bycatch. These complementary approaches were used to help account for different sources of uncertainty. <br>3. The white-chinned petrel...
