Brain aging phenomena in migrating sockeye salmon Oncorhynchus nerka nerka

, 2018
Aging, a process occuring in all vertebrates, is closely related to a loss in physical and functional abilities. There is widespread interest in clarifying the relevance of environmental, metabolic, and genetic factors for vertebrate aging. In the Pacific salmon a dramatic example of aging is known. Looking for changes in the salmon brain, perhaps even

Satellite-Based Time Series of Chlorophyll in Chilko Lake, British Columbia, Canada

Canadian Journal of Remote Sensing, 2019
In Canada, many northern lakes are remote and difficult to access, with limited limnological data. Satellite sensors provide widespread coverage and growing time series of data unavailable via conventional sampling, but global validation is still limited.

Developing molecular classifiers to detect environmental stressors and smolt stages in sockeye salmon, Oncorhynchus nerka

Scientific Reports
Climate change is increasingly affecting Pacific salmon to combinations of thermal, hypoxic, and osmotic stressors that can impair survival. Although genomic tools have enabled detailed insight into stressor responses under controlled conditions, field ...

Genetic and phenotypic diversity in sockeye salmon, Oncorhynchus nerka

, 2013
The research described here is the collective efforts of my MS work in two labs at the Univeristy of Washington, the Seeb Lab and the Roberts Lab, on two different projects. The first chapter was motivated by a need for improved genetic tools for the management of sockeye salmon specifically those populations inhabiting Bristol Bay.

Возрастной состав чукотской нерки Oncorhynchus nerka

Известия ТИНРО (Тихоокеанского научно-исследовательского рыбохозяйственного центра), 2014
Long-term data on age composition for Chukchi populations of sockeye salmon are presented. Spawners of 23 ages are recognized in the period 1970-2013 for 10 populations: 2+, 3+, 0.1+, 0.2+, 0.3+, 0.4+, 0.5+, 1.1+, 1.2+, 1.3+, 1.4+, 1.5+, 2.1+, 2.2+, 2.3+, 2.4+, 2.5+, 3.1+, 3.2+, 3.3+, 3.4+, 4.2+, and 4.3+. The brood stock basis is formed by fiveand six-

Vertical eDNA distribution of cold‐water fishes in response to environmental variables in stratified lake

Ecology and Evolution
In summer, the survival zones of cold‐water species are predicted to narrow by both increasing water temperatures from the surface and by expanding hypoxic zones from the lake bottom.

Travel specific resource selection by female Kodiak brown bears during the sockeye salmon spawning season

Movement Ecology
Background Access to salmon resources is vital to coastal brown bear (Ursus arctos) populations. Deciphering patterns of travel allowing coastal brown bears to exploit salmon resources dispersed across the landscape is critical to understanding their ...
