Shifting stage‐specific constraints on productivity shape recovery potential for Yukon River Chinook salmon

Ecological Applications, Volume 36, Issue 3, April 2026.
Abstract Identifying key life history periods in which population productivity is constrained represents a persistent challenge in conservation and natural resource management. For species with complex life cycles, such as Pacific salmon (Oncorhynchus spp.), population dynamics may be shaped by interactions between natural and anthropogenic impacts ...

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 ...

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).

A call for evidence‐based conservation: Securing the future of waterbirds along the East Asian‐Australasian flyway

Journal of Applied Ecology, Volume 63, Issue 4, April 2026.
The modified PSR framework proved valuable for assessing conservation effectiveness and identifying research gaps for waterbirds in the EAAF. Recognizing similar threats to other migratory species globally, we urge action to: (1) prioritize regionally relevant research validating frontline conservation actions, (2) enhance communication between ...

Test of light emitting diodes (LED) as a possible bycatch mitigation measure in a gillnet fishery

Global Ecology and Conservation
Substantial seabird bycatch occurs in North Atlantic lumpfish fisheries, potentially impacting seabird populations and raising concerns about the fisheries’ sustainability. Despite increased efforts to address this issue, existing approaches have yielded

Bycatch-threatened seabirds disproportionally contribute to community trait composition across the world

Global Ecology and Conservation
Human pressures in the ocean are restructuring biological communities, driving non-random extinctions, and disrupting marine ecosystem functioning. In particular, fisheries bycatch, the incidental mortality of non-target species, is a major threat to ...

Ecosystem Impacts of the Landing Obligation for Unwanted Catch in Thermaikos Gulf (Greece)

Fisheries Management and Ecology, Volume 33, Issue 2, Page 246-259, April 2026.
ABSTRACT Discards by marine commercial fisheries have been an issue of major concern to the scientific community in recent years. We modeled the ecological and trophic consequences of a mandatory landing obligation (LO) regulated by the reformed Common Fisheries Policy [Regulation (EU) 1380/2013] on the Thermaikos Gulf ecosystem (northwestern Aegean ...
