Abstract: This layer is exported from LG_Coho_Kriging_ClipAlb83 layer from the Conservation Genetics Laboratory, US Fish and Wildlife Service, Anchorage, Alaska. The layer depicts the predicted spatial distribution of the first principle component (PC1), which represents 75% of the total genetic variation in chum salmon across three watersheds (Norton Sound and the Yukon and Kuskokwim rivers) of subarctic North America. The PC1 values were derived for each population from allele frequency data and then extrapolated to the entire area (Norton Sound, and the Yukon and Kuskokwim rivers) using the ordinary kriging function in the Geostatistical Analyst tool in ArcGIS (ESRI) version 9.2. The latitudinal trend in color change suggests variation in genetic diversity occurs mainly along an east - west (or coastal - inland) axis. Purpose: To assess the spatial pattern of genetic variation in chum salmon from Norton Sound and the Yukon and Kuskokwim rivers and to assess if the spatial patterns of genetic variation in Chinook, chum, and coho salmon are congruent.
