Patterns of natural selection and demography in coastal Oregon coho salmon (Oncorhynchus kisutch) populations : evidence from neutral and olfactory receptor gene-linked markers

Creator:

Johnson, Marc Aaron

Abstract:

For Pacific salmon, the evolution of local adaptations depends upon the species' propensity to return, or "home", to natal streams at time of reproduction. Pacific salmon use olfactory cues to guide homing behavior, yet little is known about the genetics of olfaction in salmon. In this study, I use putatively...

DISSERTATION OF Marc Aaron Johnson for the degree of Doctor of Philosophy in Fisheries Science presented
Genetic patterns of demography and diversity in eastern North Pacific rockfishes (genus Sebastes)

Creator:

Johansson, Mattias L.

Abstract:

The 100 North Pacific rockfish species in the genus Sebastes are highly diverse. Rockfishes fertilize their eggs internally and release swimming larvae. Complex courting behaviors may allow female rockfish to be selective about their mates and may promote and maintain speciation. In this study, I applied genetic techniques to survey...
