This study provides the first comprehensive, regionally scalable distribution estimates for pinnipeds across the NWES and its constituent countries. The modelling framework is adaptable to other central‐place and migratory species, supporting transboundary biodiversity assessments and international conservation policy. We discuss common limitations and

DNA metabarcoding as a marine conservation and management tool: A circumpolar examination of fishery discards in the diet of threatened albatrosses [PDF]
Almost all of the world's fisheries overlap spatially and temporally with foraging seabirds, with impacts that range from food supplementation (through scavenging behind vessels), to resource competition and incidental mortality. The nature and extent of

Many seabird species are in decline and population demographic models are important for revealing the causes and developing conservation strategies. Natal and breeding dispersal are key parameters of such models but can be challenging to estimate and may vary by sex.

Atlantic Herring - A Keystone Species in the Northwest Atlantic [PDF]
The Atlantic herring (Clupea harengus) is one of the most important fishes in New England. This energy-rich species plays a vital role in the region's marine ecosystem, serving as food for many of the ocean's key predators.

How far animals travel to gather food for offspring or themselves is a central component of ecology. Among birds, the ‘foraging range’ (straight‐line distance between a central place and a destination) is used to assess potential interactions with anthropogenic stressors such as wind farms.

A description of the gross pathology of drowning and other causes of mortality in seabirds
Background Mortality of seabirds due to anthropogenic causes, especially entrapment in fishing gear, is a matter of increasing international concern.

Impacts of fisheries on seabird communities
Long-line by-catch of albatrosses and petrels may soon lead to species extinctions. Set-net bycatch has caused major reductions in certain seabird populations. Some fisheries may decrease numbers of seabirds by reducing abundance of prey-fish.

Options for Differential Management and Monitoring of Seabird Bycatch WCPFC-SC6-2010/EB-WP-05 [PDF]
At WCPFC-SC5 it was agreed to undertake further work to validate the spatial risk assessment (ERA) on seabirds to determine initial spatial zones for the differential management and monitoring of seabird bycatch.

Incidental mortality of seabirds caused by interactions with the warp wires of trawl vessels in Australia’s Commonwealth-managed Southern and Eastern Scalefish and Shark Fishery has been reported by on-board observers.

A comparison of the Bering Sea, Gulf of Alaska, and Aleutian Islands large marine ecosystems through food web modeling / by K. Aydin ... [et al.] [PDF]
Detailed mass balance food web models were constructed to compare ecosystem characteristics for three Alaska regions: the eastern Bering Sea (EBS), the Gulf of Alaska (GOA), and the Aleutian Islands (AI). This paper documents the methods and data used to
