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.

Shifting Patterns of Nitrogen Excretion and Amino Acid Catabolism Capacity during the Life Cycle of the Sea Lamprey (\u3cem\u3ePetromyzon mariunus\u3c/em\u3e) [PDF]

open access: yes, 2006
The jawless fish, the sea lamprey (Petromyzon marinus), spends part of its life as a burrow-dwelling, suspension-feeding larva (ammocoete) before undergoing a metamorphosis into a free swimming, parasitic juvenile that feeds on the blood of fishes.

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.

Consumption Rates, Evacuation Rates and Diets of Pygmy Killifish, Leptolucania ommata, and Mosquitofish, Gambusia affinis in the Okefenokee Swamp [PDF]

open access: yes, 1991
I studied feeding dynamics of Leptolucania ommata and Gambusia affinis in the Okefenokee Swamp. Both fishes mainly ate insect larvae (such as Chironomidae) and Cladocera. Evacuation rates ranged from 0.143 (L. ommala in winter) to 0.279/hour (L.

Age and length composition of Columbia Basin chinook, sockeye, and coho salmon at Bonneville Dam in 2000 [PDF]

open access: yes, 2001
In 2000, representative samples of adult Columbia Basin chinook (Oncorhynchus tshawytscha), sockeye (O. nerka), and coho salmon (O. kisutch), populations were collected at Bonneville Dam. Fish were trapped, anesthetized, sampled for scales and biological

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,

Snake River Sockeye Salmon (Oncorhynchus Nerka) Habitat/Limnologic Research

open access: yes, 1992
This report outlines long-term planning and monitoring activities that occurred in 1991 and 1992 in the Stanley Basin Lakes of the upper Salmon River, Idaho for the purpose of sockeye salmon (Oncorhynchus nerka) recovery. Limnological monitoring and experimental sampling protocol, designed to establish a limnological baseline and to evaluate sockeye ...
