Conserving threatened species often requires effective predator suppression strategies, particularly on islands where introduced predators pose significant threats. Density‐impact functions provide a framework to quantify the relationships between predator abundance and impact but are currently limited to a single species with invariant impact.

Mortality of Migratory Birds from Marine Commercial Fisheries and Offshore Oil and Gas Production in Canada [PDF]
There is an imminent need for conservation and best-practice management efforts in marine ecosystems where global-scale declines in the biodiversity and biomass of large vertebrate predators are increasing and marine communities are being altered.

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.

Pollution, habitat loss, fishing and climate change as critical threats to penguins [PDF]
Cumulative human impacts across the world’s oceans are considerable. We therefore examined a single model taxonomic group, the penguins (Spheniscidae), to explore how marine species and communities might be at risk of decline or extinction in the ...

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.

Catch Rates with Variable Strength Circle Hooks in the Hawaii-Based Tuna Longline Fishery [PDF]
The Hawaii-based deep-set longline fleet targets bigeye tuna [Thunnus obesus (Lowe, 1839)] and infrequently takes false killer whales [FKW , Pseudorca crassidens (Owen, 1846)] as bycatch. From 2004 to 2008 with 20%–26% observer coverage, nine mortalities

Bycatch of marine mammals and seabirds: Occurrence and mitigation
Gillnet fisheries are generally considered environment-friendly, causing limited bottom-impact and generating high-quality fish. Nevertheless, gillnets are also associated with high risks of bycatch of non-target animals, including seabirds and marine mammals. To fulfil Denmark’s obligations with regards to European legislations and other international
