Using environmental DNA to identify emerging Pacific salmon habitats and support Indigenous governance

Ecological Applications, Volume 36, Issue 7, October 2026.
Abstract Northern watersheds are facing rapid hydroclimatic reorganization driven by climate warming, glacier retreat, and intensifying land use. These changes are altering the distribution and accessibility of aquatic habitats, creating both risks and opportunities for cold‐adapted species such as Pacific salmon (Oncorhynchus spp.).

Sociability Under Anthropogenic Change: From Individual Behaviour to Population‐Level Consequences

Ecology and Evolution, Volume 16, Issue 10, October 2026.
Our review synthesises empirical and theoretical research on how anthropogenic environmental change reshapes animal social behaviour from individuals to populations. We use sociability as an individual‐level lens, distinguishing context‐dependent expression from repeatable interindividual differences and linking both to social relationships, network ...

Legacy habitat contamination as a limiting factor for Chinook salmon recovery in the Willamette Basin, Oregon, USA.

PLoS ONE, 2019
In the western United States, the long-term recovery of many Pacific salmon populations is inextricably linked to freshwater habitat quality. Industrial activities from the past century have left a legacy of pollutants that persist, particularly near ...

Opportunistic Feeding and Parasite Assemblages in Sei Whales (Balaenoptera borealis) From Southern Chile Revealed by DNA Metabarcoding

Ecology and Evolution, Volume 16, Issue 10, October 2026.
This study represents the first metabarcoding‐based description of prey composition and parasite‐associated taxa in stranded sei whales from southern South America. ABSTRACT Balaenopterid whales are major consumers in pelagic ecosystems and play a fundamental role in marine food webs.

A depth model for informing Chinook salmon bycatch risk in the Gulf of Alaska

Animal Biotelemetry
Background Bycatch of Chinook salmon (Oncorhynchus tshawytscha) in the Gulf of Alaska walleye pollock (Gadus chalcogrammus) fishery poses both conservation and management challenges. While fleet communication and excluder devices have improved mitigation

The Role of Sediment Supply on Fish Habitat Dynamics of a Morphologically Active River Widening

River Research and Applications, Volume 42, Issue 8, Page 1755-1770, October 2026.
ABSTRACT Restoration measures, such as river widening, aim to reactivate key morphodynamic processes, which are critical drivers of fluvial habitat dynamics. While some evidence supports the important role of sediment supply on river widening's morphology, its link to fish habitat availability and dynamics remains unclear.

Transcriptional breakpoints as predictors of thermal thresholds in a climate‐impacted stenothermal fish

Functional Ecology, Volume 40, Issue 10, Page 3034-3047, October 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The biogeography of ectotherms is greatly influenced by their thermal tolerance, which is expected to be tightly coupled to aerobic performance. However, preferred temperatures of ectotherms often deviate substantially from aerobic performance optima. This suggests that

Compounding Impacts—Genomic Exploration of the Potential Effect of Domestic Introgression on Climate Adaptation in Atlantic Salmon (Salmo salar)

Evolutionary Applications, Volume 19, Issue 10, October 2026.
ABSTRACT Predicting population, species, and community responses to climate change is critical for the successful management of wild ecosystems. However, climate change does not act alone. Interactions among climate change and other anthropogenic threats could significantly complicate predictions of global change yet have rarely been examined.

Impact of Environmental Conditions on the Spawning Migration of Sea Trout (Salmo trutta L.) in Two Large, Sub‐Arctic River Systems

Fisheries Management and Ecology, Volume 33, Issue 5, Page 879-893, October 2026.
ABSTRACT The global decline in salmonid stocks has increased the need for knowledge of local adaptations and life history strategies of salmonids. In this study, we used radio‐telemetry tracking data from sea trout populations in two large high‐latitude rivers to model upstream spawning migration speed of trout in response to prevailing environmental ...

Sex‐Specific Atlantic Salmon Upstream Passage and Fallback at a Natural Cascade After Dam Removal

Fisheries Management and Ecology, Volume 33, Issue 5, Page 963-976, October 2026.
ABSTRACT In the Boquet River (NY, USA) a low‐head dam set above a ~200‐m bedrock cascade was removed in 2015. We used radio‐telemetry to assess landlocked Atlantic salmon passage at the remaining cascade (2020, 2022). Across years, 52% of males (13/25) attempted cascade passage whereas females made no discernable attempts (0/11).
