Differentiating salmonid migratory ecotypes through stable isotope analysis of collagen: Archaeological and ecological applications.

PLoS ONE, 2020
The ability to distinguish between different migratory behaviours (e.g., anadromy and potamodromy) in fish can provide important insights into the ecology, evolution, and conservation of many aquatic species.

Salmon Skin Acid-Soluble Collagen Produced by A Simplified Recovery Process: Yield, Compositions, and Molecular Characteristics

Fishes, 2022
Acid-soluble collagen (ASC) is generally extracted by acid solubilization, followed by precipitation and dialysis. Such a process is typically time consuming and tedious, especially for dialysis.

Comparative foraging ecology of lynx and coyotes in three Gulf of Alaska national parks

Ecosphere, Volume 17, Issue 8, August 2026.
Abstract Consumers exhibit varying degrees of dietary specialization, with foraging strategies shaped by both evolutionary history and local food availability. In boreal systems, Canada lynx are considered snowshoe hare specialists, whereas coyotes are classically generalist foragers capable of exploiting diverse resources.

Opening a can of worms: Archived canned fish fillets reveal 40 years of change in parasite burden for four Alaskan salmon species

Ecology and Evolution
How has parasitism changed for Alaskan salmon over the past several decades? Parasitological assessments of salmon are inconsistent across time, and though parasite data are sometimes noted when processing fillets for the market, those data are not ...

Spatial and ecological structure of the sockeye salmon population Oncorhynchus nerka of Kuril Lake [PDF]

E3S Web of Conferences
This study examines the genetic structure of sockeye salmon populations in Kuril lake basin, focusing on the allelic frequencies of SNP loci that potentially carry an adaptive load. Our results reveal the division of sockeye salmon populations into three

Increasing artificial light at night enhances salmonid predator foraging efficiency in an urbanized lake

Limnology and Oceanography, Volume 71, Issue 8, August 2026.
Abstract Artificial light at night (ALAN) poses a threat to ecosystems globally. It includes both direct and indirect light, or skyglow, which occurs when ALAN scatters in the atmosphere, extending beyond its original source. We analyzed ALAN trends in Lake Washington, WA, from 2014 to 2023 using Visible Infrared Imaging Radiometer Suite (VIIRS ...

Genetic and Ecological Management of Pacific Salmon Fisheries for the 21st Century

Fisheries Management and Ecology, Volume 33, Issue 4, Page 633-645, August 2026.
ABSTRACT Based on ecological adaptation theory, tremendous effort is being spent on measures that are eliminating salmon hatcheries and fishing opportunities with the intention of protecting wild runs deemed to be of particular genetic importance to the survival of the species.

Changing Pacific Salmon Nursery Lake Ecosystem Dynamics Over Centuries to Millennia: Insights From Sedimentary DNA Metabarcoding

Environmental DNA, Volume 8, Issue 4, July‐August 2026.
Sedimentary DNA metabarcoding tracks long‐term eukaryotic community change in Pacific salmon nursery lakes, revealing potential land‐use and climate influences on algal communities and resilience indicators. ABSTRACT Pacific salmon are keystone species in North Pacific freshwater, riparian, and marine ecosystems, but many populations have declined or ...

Direction and magnitude of natural selection on body size differ among age‐classes of seaward‐migrating Pacific salmon

Evolutionary Applications, 2020
Due to the mediating role of body size in determining fitness, the “bigger‐is‐better” hypothesis still pervades evolutionary ecology despite evidence that natural selection on phenotypic traits varies in time and space.

Spatiotemporal Assessment of Groundwater Interactions With a Regulated River: A Case Study of the Nechako River, Canada

River Research and Applications, Volume 42, Issue 6, Page 1172-1187, July 2026.
ABSTRACT Regulated rivers represent complex hydrological systems where groundwater–surface water interactions are governed by natural conditions and human interventions. This study investigates the spatiotemporal dynamics of groundwater–surface water exchanges in the Nechako River, British Columbia (Canada), using numerical simulations.
