Ecological restoration hierarchy as a lens to reveal the foundational economic and legal structures impeding restoration

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction Biodiversity loss is accelerating due to habitat destruction, economic expansion, and insufficient conservation efforts. Traditional mitigation strategies, which focus on minimizing harm rather than reversing damage, are inadequate for achieving net biodiversity gain. Objectives This article introduces the restoration hierarchy, a

The Feeding Ecology of Invasive Pink Salmon Juveniles in Northern Norwegian Rivers and Their Role as Prey to Native Salmonids

open access: yesEcology of Freshwater Fish, Volume 35, Issue 3, July 2026.
ABSTRACT Increasing numbers of invasive Pacific pink salmon (Oncorhynchus gorbuscha) are spawning in northern Norwegian rivers, leading to large numbers of juveniles migrating to coastal waters. This raises concerns about food competition with native salmonids in rivers, although details about the timing and intensity of pink salmon feeding and the ...

Delousing performance of ballan wrasse (Labrus bergylta) and lumpfish (Cyclopterus lumpus): seasonal consistency and the challenge of cryptic lice for lumpfish

open access: yesPest Management Science, Volume 82, Issue 5, Page 4661-4668, May 2026.
Ballan wrasse and lumpfish effectively reduce sea lice on salmon year round, although lumpfish struggle with cryptic lice, highlighting new considerations for lice management. Abstract BACKGROUND Cleaner fish play a crucial role in controlling caligid sea lice in Atlantic salmon aquaculture across the North Atlantic.

Production of single-domain magnetite throughout life by sockeye salmon, Oncorhynchus nerka [PDF]

open access: yes, 1988
Although single-domain particles of biogenic magnetite have been found in different species of pelagic fishes, nothing is known about when it is synthesized, or about whether the time during life when it is produced is correlated with the development of

Injury Risks to a Migratory Freshwater Fish During Downstream Passage Through a Regulated Floodplain Outlet: A Case Study on Golden Perch ( Macquaria ambigua )

open access: yesRiver Research and Applications, Volume 42, Issue 4, Page 812-823, May 2026.
ABSTRACT River infrastructures such as weirs, dams, inlet and outlet regulators often impair connectivity, leading to degradation and loss of key habitats for riverine fishes. This also holds true for golden perch ( Macquaria ambigua Richardson), a migratory species in Australia's Murray–Darling Basin. Regulated outlets between main stem and floodplain

A Method to Implement Natural Flow Regimes for Regulated Rivers

open access: yesWater Resources Research, Volume 62, Issue 5, May 2026.
Abstract Rivers throughout the world have been dammed for flood control, irrigation, hydropower, and water storage for centuries. Dams service the economic and development needs of societies, but degrade the ecology of rivers. To conserve diminishing aquatic species and their habitats, methods are needed to help managers implement flow releases with ...
