| population subdivision in westslope cutthroat trout (oncorhynchus clarki lewisi) at the northern periphery of its range: evolutionary inferences and conservation implications. | westslope cutthroat trout (oncorhynchus clarki lewisi, salmonidae) are native to the upper columbia, missouri, and south saskatchewan river drainages of western north america and are at the northern periphery of their range in southeastern british columbia, canada. we examined geographical variation in allele frequencies at eight microsatellite loci in 36 samples of westslope cutthroat trout from british columbia to assess levels of population subdivision and to test the hypothesis that differen ... | 2003 | 12969465 |
