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.

Transcriptional Response to Acute Thermal Exposure in Juvenile Chinook Salmon Determined by RNAseq. [PDF]

open access: yes, 2015
Thermal exposure is a serious and growing challenge facing fish species worldwide. Chinook salmon (Oncorhynchus tshawytscha) living in the southern portion of their native range are particularly likely to encounter warmer water due to a confluence of ...

Effects of an Inert, Palatable Resource Subsidy on Live Prey Selection by Juvenile Fish [PDF]

open access: yes, 2012
Resource subsidies, defined as energy and nutrients that enter ecosystems from external sources, can have diverse and complex effects on consumer populations.

Feeding ecology of juvenile Pacific salmon (Oncorhynchus spp.) in a northeast Pacific fjord: diet, availability of zooplankton, selectivity for prey, and potential competition for prey resources [PDF]

open access: yes, 2010
We investigated the feeding ecology of juvenile salmon during the critical early life-history stage of transition from shallow to deep marine waters by sampling two stations (190 m and 60 m deep) in a northeast Pacific fjord (Dabob Bay, WA) between May ...

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 ...

open access: yesИсследования водных биологических ресурсов Камчатки и северо-западной части Тихого океана, 2010
The results of the analysis of the interannual nuclear DNA micrisatellite locus variation level for sockeye salmon in Kurilskoye Lake for the period of 11 years (from 1989 to 2000) have been demonstrated. Analysis of the allelic frequencies for 14 loci, including Ots2, Ots3, Ots100, Ots103, Ots107, Ots108, One8, Omy77, Oki1a, Oki1b, Oki6, Oki10, Oki16,
