چکیده انگلیسی
Coho salmon (Oncorhynchus kisutch) utilize olfactory cues to recognize and home to natal streams during spawning migrations. Chemically distinct river systems may promote directional selection for appropriately tuned olfactory receptor repertoires among Coho populations. Here, we use FST outlier methods to test for a signal of selection over olfactory receptor gene-linked markers, characterized in Coho populations from four geographically proximate, but ecologically distinct rivers. We report evidence for directional selection over one such marker, OkiOR3001, and document substantially higher levels of genetic structure among Coho populations from Oregon coastal lakes than previously observed with putatively neutral microsatellites.
