...Joely G. DeSimone; Bret W. Tobalske; Creagh W. Breuner ABSTRACT Migration allows animals to use resources that are variable in time and/or space, with different migratory strategies depending on the predictability of resource variation. When food varies seasonally, obligate migrants anticipate...

This suggests that the large-scale movements of pink salmon across the North Pacific may be driven largely by their innate use...
