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 ...

Proposal of extension of research block 48.6_2 to complete planned research and examine the habitat model and the stock structure
Abstract: Here we propose the northeastward of research block of 48.6_2 along ridges to promote ... sufficient utilization of the catch limit, which enable us to complete planned research, evaluate the habitat ... model and elucidate stock structure. The distribution of densities (catch per haul in 20-minute grid) of ... its southeastern bank (south of ca. 55.2°S) with higher fish densities but scarce in the northern area ...

Features of chronology and breeding success of Pygoscelis papua and Pygoscelis adeliae penguins in the Wilhelm Archipelago (CCAMLR Subarea 48.1)
Abstract: We aim to investigate the qualitative changes in the habitats of two most common ... (Adelie) penguins in the CCAMLR Subarea 48.1 under the impact of climate changes and krill fishery. To ... minimize the effect of human disturbance on the breeding success and survival of chicks and avoid ... disturbance to the penguins, the new method of registration using time-lapse cameras have been installed in ...
