Charlie, may I suggest that you read up on the local adaptation of common
livestock, such as sheep, goats, or cattle.  Such adaptation has to do with
responses to the different environments, elevation (oxygen availability),
foraging preferences or aversion (such as selection for bees that avoid
local toxic plants, such as Buckeye in California), as well as adapting to
the local plant phenology, to name a few.

You could also luck at *Homo sapiens* as an example--how different races
adapted physiologically, morphologically, and behaviorally to different
ecoregions.
