[ send me this essay ]
A 5 page review of this article exploring the geographic variance of food preference. Arnold’s article represents one of just a few studies which have explored geographic variation from a behavioral standpoint. Arnold chose to investigate the slug-eating behavior which typifies garter snake populations in mollusk-rich environments, asserting that his study “represents the most thorough documentation of geographic variation in behavior in the vertebrate literature”. Arnold crosses individuals from inland and coastal populations of garter snakes to test the food preference of the first generation offspring. He concludes that there is no perfect intermediacy in regard to the feeding preferences tested. No additional sources are listed.
