Notes | "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 neutral microsatellite markers to estimate demographic parameters and describe the population genetic structure of Oregon Coastal coho salmon (Oncorhynchus kisutch). . . I then used genomic sequence data from nine species of salmon and trout to infer the evolutionary history for eight olfactory receptor genes. . . Finally, I used molecular markers linked to olfactory receptor genes to test for a signal of selection among coho salmon populations from different rivers." (from the Abstract) Found the Coos Bay salmon were the major source of straying in the south coast, while Nehalem River salmon did most of the straying on the north coast. |
