چکیده

Conservation biology aims at assessing the status of a population, based on information which is often incomplete. Integrated population modelling based on state-space models appears to be a powerful and relevant way of combining into a single likelihood several types of information such as capturerecapture data and population surveys. In this paper, the authors describe the principles of integrated population modelling and they evaluate its performance for conservation biology based on a case study, that of the black-footed albatross, a northern Pacific albatross species suspected to be impacted by longline fishing. Le potentiel de la modélisation intégrée en biologie de la conservation : une étude de cas de l’albatros à pieds noirs (Phoebastria nigripes) Résumé : La biologie de la conservation vise à évaluer l’état d’une population à l’aide d’informations souvent incomplètes. La modélisation intégrée des populations à l’aide de modèles à espaces d’états est une méthode puissante qui permet de combiner de façon adéquate en une seule vraisemblance plusieurs types d’informations telles que des données de capture-recapture et des inventaires de population. Dans cet article, les auteurs décrivent les principes de la modélisation intégrée des populations et ils en évaluent la performance pour la biologie de préservation à l’aide d’une étude de cas portant sur l’albatros à pieds noirs, une espèce d’albatros vivant dans l’Océan Pacifique Nord vraisemblablement affectée par la pêche palangrière commerciale.

Dynamic habitat models: using telemetry data to project fisheries bycatch.

Fisheries bycatch is a recognized threat to marine megafauna. Addressing bycatch of pelagic species however is challenging owing to the dynamic nature of marine environments and vagility of these organisms. In order to assess the potential for species to overlap with fisheries, we propose applying dynamic habitat models to determine relative probabilities of species occurrence for specific ocea...

Rape and the prevalence of hybrids in broadly sympatric species: a case study using albatrosses

Conspecific rape often increases male reproductive success. However, the haste and aggression of forced copulations suggests that males may sometimes rape heterospecific females, thus making rape a likely, but undocumented, source of hybrids between broadly sympatric species. We present evidence that heterospecific rape may be the source of hybrids between Black-footed and Laysan Albatrosses (P...

Morphological and genomic comparisons of Hawaiian and Japanese Black-footed Albatrosses (Phoebastria nigripes) using double digest RADseq: implications for conservation

Evaluating the genetic and demographic independence of populations of threatened species is important for determining appropriate conservation measures, but different technologies can yield different conclusions. Despite multiple studies, the taxonomic status and extent of gene flow between the main breeding populations of Black-footed Albatross (Phoebastria nigripes), a Near-Threatened philopa...

SCIENTIFIC COMMITTEE THIRD REGULAR SESSION 13-24 August 2007 Honolulu, United States of America Quantifying the impact of longline fisheries on adult survival in the black-footed albatross WCPFC-SC3-EB SWG/IP-4

1. Industrial longline fishing has been suspected to impact upon black-footed albatross populations Phoebastria nigripes by increasing mortality, but no precise estimates of bycatch mortality are available to ascertain this statement. We present a general framework for quantifying the relationship between albatross population and longline fishing in absence of reliable estimates of bycatch rate...

Contaminant-associated alteration of immune function in black-footed albatross (Phoebastria nigripes), a North Pacific predator.

Environmental pollution is ubiquitous and can pose a significant threat to wild populations through declines in fitness and population numbers. To elucidate the impact of marine pollution on a pelagic species, we assessed whether toxic contaminants accumulated in black-footed albatross (Phoebastria nigripes), a wide-ranging North Pacific predator, are correlated with altered physiological funct...
