Research Project Report
Abstract
There is little known about the biology and behavior of the North American water vole (Arvicola richardsoni). The purpose of my study is to construct an ethogram of this interesting species including descriptions of maintance, reproductive, aggressive and marking behaviors. Notes were also taken on litters born in the lab for growth and development data. Additional data were collected on the effects of testosterone on the marking behaviors and the gland sizes. Project Number 187.
