A single generation in the wild increases fitness for descendants of hatchery‐origin Chinook salmon (Oncorhynchus tshawytscha)

Evolutionary Applications
Reintroduction is an important tool for the recovery of imperiled species. For threatened Pacific salmonids (Oncorhynchus spp.) species, hatchery‐origin (HOR) individuals from a nearby source are often used to reestablish populations in vacant ...

In‐Hatchery Survival of Chinook Salmon Using Natural and Hatchery Broodstocks

Aquaculture, Fish and Fisheries, Volume 6, Issue 4, August 2026.
ABSTRACT Natural‐origin Chinook Salmon Oncorhynchus tshawytscha have been integrated into hatchery broodstocks to mitigate the potentially negative effects of domestication in‐hatchery programmes. However, uncertainty exists about the in‐hatchery performance of the offspring of natural‐origin parents relative to the traditional hatchery broodstocks ...

Passive Water Filtration Enhances the Detection of Endangered Fish Species in Rivers: Anguilla anguilla and Salmo salar Monitoring Using qPCR

Ecology and Evolution, Volume 16, Issue 8, August 2026.
This study assesses the effectiveness of environmental DNA (eDNA) for monitoring the critically endangered Anguilla anguilla and the near‐threatened Salmo salar using quantitative PCR. Active in situ water filtration and passive metaprobe deployment were compared, showing that metaprobes provided greater sensitivity for low‐abundance species, while ...

An Analysis of Great Tit Egg Traits Across the City Mosaic: Urbanisation Does Not Affect Egg Size and Pigmentation Patterns

Ecology and Evolution, Volume 16, Issue 8, August 2026.
Based on data from over 550 great tit (Parus major) eggs collected in the city mosaic, this research finds no effect of urbanisation on egg volume or pigmentation patterns. These results suggest that urban‐driven environmental pressures may not be as strong or directional during the egg laying phase as they are at later stages of reproduction ...

Development and Genetic Monitoring of a Putatively Thiamine Deficiency Complex Tolerant Atlantic Salmon Broodstock

Ecology and Evolution, Volume 16, Issue 8, August 2026.
We introduce efforts to develop a potentially thiamine deficiency complex (TDC) tolerant Atlantic salmon broodstock via selective breeding, as well as control broodstock with higher genetic diversity (and no selection). Additionally, we develop the genetic monitoring tools (novel genetic marker panel, parentage‐based tagging) to monitor the demographic

A Generalizable Tool for Predicting Developmental Phenology for Wild Ecotherms

Ecology and Evolution, Volume 16, Issue 8, August 2026.
Custom hatch timing models developed for four North American Lithobates frog species. Models are parameterized from Moore (1939). Panels (A, B) shows differential developmental rates under varying thermal regimes and G × E interactions. ABSTRACT Development in poikilothermic organisms is strongly temperature‐dependent, particularly during early life ...

Diversity Under Pressure: Long‐Term Genetic Decline in California's Central Valley Chinook Salmon ESA Listed Runs

Ecology and Evolution, Volume 16, Issue 8, August 2026.
Chinook salmon in the Central Valley of California have notable intraspecific diversity because it is the only place where four distinct migration timings (Winter, Spring, Fall, Late‐fall) co‐occur. The Winter run is listed as Endangered and the Spring run is listed as Threatened under the Endangered Species Act. To quantify temporal changes in genetic

Stayin' alive: Strategies to reduce predation on target species are context dependent

Ecosphere, Volume 17, Issue 8, August 2026.
Abstract Restoration and conservation efforts often aim to reduce predation, particularly by reducing interactions with nonnative predators in heavily disturbed and invaded ecosystems. For Chinook salmon Oncorhynchus tshawytscha, a highly valued but declining fishery, potentially useful freshwater rearing habitat restoration strategies may include ...
