Abstract
Quinn will discuss how natural selection operates on the timing of migration and spawning by salmon. Temperature and flow are the primary physical factors in the evolution and ecology of timing. Salmon seem to be adapting to climate change. Artificial selection from hatcheries and from fisheries can counter or enhance natural selection, with important consequences for salmon.
