The foraging ecology of greyheaded mollymawks at Marion Island: in relation to known longline fishing activity [PDF]

, 2000
Incidental mortality due to longline fishing has been implicated as the main cause for the global population decline in grey-headed mollymawks (Thalassarche chrysostoma).

Population Structure and Genetic Diversity Analyses Reveal Isolation That May Imperil the Northernmost Colony of the Endangered Australian Sea Lion

Ecology and Evolution, Volume 16, Issue 2, February 2026.
Rapid warming of marine environments is threatening ecosystems, especially species at the edge of their range. This study analysed the genetic structure and diversity of Australian sea lion populations and found the northernmost population to be highly isolated with extremely low genetic variation.

Best practices for mitigating seabird bycatch on Taiwanese albacore longline fishing vessels operating in the southeastern Atlantic Ocean

Global Ecology and Conservation
Seabird bycatch—particularly involving albatrosses and petrels—remains a significant conservation concern in pelagic longline fisheries. This study evaluated the effectiveness of three mitigation measures—bird-scaring lines (BSLs), weighted branch lines,

The economic cost of seabird bycatch in Argentinean longline fisheries [PDF]

Bird Conservation International, 2011
SummarySeabird mortality in longline fisheries is believed to be an important cause of the reductions in many seabird populations worldwide, and results in reduced fishing efficiency and economic losses for fishing companies. We estimated the economic cost of not using seabird bycatch deterrents in Argentinean longline fisheries, with the intention of ...

Mortality of Migratory Birds from Marine Commercial Fisheries and Offshore Oil and Gas Production in Canada [PDF]

, 2013
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.

Emergence, spread, and impact of high‐pathogenicity avian influenza H5 in wild birds and mammals of South America and Antarctica

Conservation Biology, Volume 40, Issue 1, February 2026.
Abstract The currently circulating high‐pathogenicity avian influenza (HPAI) virus of the subtype H5 causes variable illness and death in wild and domestic birds and mammals, as well as in humans. This virus evolved from the Goose/Guangdong lineage of the HPAI H5 virus, which emerged in commercial poultry in China in 1996, spilled over into wild birds,

The incidental capture of seabirds by Spanish drifting longline fisheries in the western Mediterranean Sea

Scientia Marina, 2003
The western Mediterranean Sea is an important fishing area for the Spanish drifting longline fleet, targeting swordfish (Xiphias gladius), bluefin tuna (Thunnus thynnus) and albacore (T. alalunga).

Pollution, habitat loss, fishing and climate change as critical threats to penguins [PDF]

, 2014
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 ...
