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

open access: yesCanadian 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.

Возрастной состав чукотской нерки Oncorhynchus nerka

open access: yesИзвестия 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-

Genetic and phenotypic diversity in sockeye salmon, Oncorhynchus nerka

open access: yes, 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.

On the Scale and Stock of the Red Salmon, Oncorhynchus nerka, Migrating to the Kamchatka

open access: yesNIPPON SUISAN GAKKAISHI, 1948
With regard to the river-life zone, the scales of the red salmon obtained from the 9 localities given in the Fig.1, are referable to 6 types (A, B1, B2, BC, . C and Ck). Of the stock of the salmon, 4 groups are found to exist basing on the scaletype-composition. The 1st group is found at Olyutorskii, mostly composed of the types B1 and B2.

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

open access: yesEcology 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

open access: yesMovement 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 ...
