Hansen Creek had significantly smaller adipose
fins for their length than males from the remaining
populations. Hansen Creek males are also
shallower bodied (i.e., more fusiform) than males
from Bear Creek and Yako Creek, and Woody
Island males are the most deep bodied (Quinn
et al. 2001), even after correcting for differences
in body length among these populations. These
differences in body depth are also paralleled by
differences in weight at a given length (Hansen
< Bear < Wood Island, etc., Quinn unpublished
data). Previous work in the Hansen Creek
population indicates that shallow bodies result
from strong selection against large size from both
the shallow water and subsequent size-selected
risk of stranding (Quinn and Buck 2001; Carlson
and Quinn 2007) as well as size-selective predation
by brown bears, Ursus arctos (Quinn and
Buck 2001). Like Hansen Creek, A Creek is
shallow and characterized by intense bear predation
and individuals are correspondingly shallowbodied.
