BIOL311 Mammalogy (2,3)        3 An investigation of the natural history, biology and taxonomy of mammals. Techniques for measuring and monitoring mammalian populations are presented. The laboratory focuses on field techniques and the identification by skin, skull and track of mammals of the Great Lakes region. Prerequisite: BIOL243. Although the number of mammalian species is rather small compared to other animal taxa, the diversity of this group is truly remarkable.  Furthermore, the morphological, physiological, and behavioral adaptations exhibited by mammals provides a keen insight into the power of natural selection. Lectures are presented from an evolutionary perspective.  We begin with a description of the abiotic and biotic conditions which led to the evolution of mammals.  We continue with an anlaysis of specific adaptations (e.g. homiothermy, tribosphenic molars, viviparity) of early mammals and their subsequent radiation.  A brief survey of extant mammalian orders is followed by discussions of the ecophysiology and behavior of mammals with particular emphasis on thermoregulation, sensory systems, mating behavior, and reproductive physiology. The focus in the laboratory is the identification of mammals common to the Great Lakes region.  Identification to species by skin, skull and track is required.  I do not, however, place too much emphasis on memorization.  Rather, I stress the value of learning to effectively use dichotomous keys.  This skill enables students to accurately identify specimens regardless of where they are in the country or the world.  The ability to use keys transends mammalogy and is useful for identifying individuals from any group of organisms.  To this end,we spend the first few laboratory sessions reviewing mammalian anatomy and becoming familiar with the terminology and measurements commonly used in field guides and keys.  As time and weather permit, we may conduct a small-scale trapping survey to familiarize students with the technical and ethical guidlines required of such endeavors. updated 11/18/2010
