of chum salmon (Oncorhynchus keta) was examined with a survey of
microsatellite variation to describe the distribution of genetic
variation and to evaluate whether chum salmon may have
originated from two or more glacial refuges following dispersal
to newly available habitat after glacial retreat. Variation at
14 microsatellite loci was surveyed for over 53,000 chum salmon
sampled from over 380 localities ranging from Korea through
Washington State. An index of genetic differentiation, FST, over
all populations and loci was 0.033, with individual locus values
ranging from 0.009 to 0.104. The most genetically diverse chum
salmon were ob
