Population dynamics of wandering albatross Diomedea exulans and Amsterdam albatross D. amsterdamensis in the Indian Ocean and their relationships with longline fisheries: conservation implications
Abstract: Studies carried out over the past three decades at Crozet and Kerguelen Islands in the ... 1986 have shown slow recovery. The population of the endangered Amsterdam albatross Diomedea ... study of the Crozet population indicates that the earlier decline was mainly the result of increased ... adult mortality, and secondarily of low recruitment. Satellite tracking studies of breeding birds and ...

The incidence of plastic in the diets of Antarctic seabirds
Abstract: We investigated the diets of seabirds at sea in the Antarctic from 1976 to 1988. During ... , we collected or pumped the stomachs of 1,223 seabirds of 23 species. The stomach contents of species ... live prey. Among species that feed a t the surface, most of which eat both live and dead organisms ... , incidence of plastic was highest among the smaller ones and those that are omnivores, or feed on zooplankton ...

Maximum entropy reconstruction of stock distribution and inference of stock density from line-transect acoustic survey data
distribution from acoustic line-transect data. MaxEnt is founded on the bedrock of probability theory and ... allows the most efficient possible use of known data in the inference process. The method takes explicit ... account of spatial correlation in the observed data and seeks to reconstruct a distribution of density ... maximized. The method is iterative and uses the Bayesian approach of evaluating the posterior probability of ...
