Climate, Demography, and Zoogeography Predict Introgression Thresholds in Salmonid Hybrid Zones in Rocky Mountain Streams. [PDF]
PLoS ONE, 2016 Among the many threats posed by invasions of nonnative species is introgressive hybridization, which can lead to the genomic extinction of native taxa.

Seasonal changes in abundance of brown trout (Salmo trutta) and rainbow trout (s. gairdnerii) assessed by drift diving in the Rangitikei river, New Zealand [PDF]
, 1985 Numbers and approximate sizes of brown trout (Salmo trutta L.) and rainbow trout (5. gairdnerii Richardson) were estimated by snorkel divers at 6 sites in the middle reaches of the Rangitikei River, North Island, New Zealand, over 14 months.

Behavioural thermoregulation in cold‐water freshwater fish: Innate resilience to climate warming?
Fish and Fisheries, Volume 24, Issue 1, Page 187-195, January 2023., 2023 Abstract Behavioural thermoregulation enables ectotherms to access habitats providing conditions within their temperature optima, especially in periods of extreme thermal conditions, through adjustments to their behaviours that provide a “whole‐body” response to temperature changes.

Weight, Length, and Growth in Cutbow Trout (Oncorhynchus mykiss x clarkii) [PDF]
, 2011 Background: The cutbow trout (Oncorhynchus mykiss x clarkii) is a fertile hybrid of rainbow and cutthroat trout. Little published length-weight data is available for this hybrid, and a standard weight curve is not established. Eleven Mile Reservoir is

Egestion rates of microplastic fibres in fish scaled to in situ concentration and fish density
Freshwater Biology, Volume 68, Issue 1, Page 33-45, January 2023., 2023 Abstract Microplastics (particles <5 mm) are commonly found in aquatic organisms across taxonomic groups and ecosystems. However, the egestion rate of microplastics from aquatic organisms and how egestion rates compare to other rates of microplastic movement in the environment are sparsely documented.
