Mammals Of Utah County, James W. Bee

Student Works

Based on the premises that an accurate determination and description of the mammals of Utah County is a prerequisite for subsequent research in ecology, geographic distribution and evolutionary taxonomy, this thesis is submitted. While it is essentially taxonomic, there are included related subjects to permit a more thorough interpretation of the subject as a whole.

Summarizing, the objectives are:

• a. To list and key the known mammals of Utah County with descriptions and measurements.
• b. To ascertain their geographic range within the county.
• c. To present significant ecological and geological data for the proper appreciation of the problems of evolutionary …
