Title: Chinook_Fst |
Abstract: This layer is exported from LG_Chinook layer from the Conservation Genetics Laboratory, US Fish and Wildlife Service, Anchorage, Alaska. The layer depicts population specific Fst values computed using the method described by Foll and Gaggiotti 2006, Genetics 174:875-893 as implemented in the computer program GESTE version 2.0. Larger values (red) denote populations that are more genetically isolated whereas smaller values (green) denote populations that are less genetically isolated. The population specific values were used in an analysis to assess and compare the extent to which nine habitat features from four general categories (spatial isolation, habitat size, climate, and ecology) explain the degree of genetic isolation. The analysis was performed using GESTE version 2.0 and the nine habitat variables included: waterway distance to the coast, median pairwise waterway distance from each location to all other locations (similar to connectivity), elevation, migration difficulty (waterway distance to the coast x elevation), home subbasin area, home river length, mean annual precipitation, ecoregion, and permafrost region. The results suggest that the spatial distribution of population-specific Fst values for Chinook salmon may be partially explained by a combination of mean annual precipitation, waterway distance to the coast, and home subbasin area. No single variable was strongly correlated to the Fst values. Purpose: To assess and compare the extent to which habitat features from four general categories (spatial isolation, habitat size, climate, and ecology) explain population structure in Chinook, chum and coho salmon from Norton Sound and the Yukon and Kuskokwim rivers.
