Sylvester Allred's anatomical studies have revealed that natural populations of the small game species, the Abert squirrel, is reproductively active from late winter to late fall.
Histological examination of reproductive tissues indicates evolutionary divergence of populations of the squirrel on the north rim of the Grand Canyon from populations on the south rim.
These findings are relevant to the development of small game management policy in the Arizona Game and Fish Department.
Brief teaching philosophy
Students should expect their professors to be well organized, knowledgeable, passionate, and enthusiastic about their subjects. Professors should expect their students to come to class prepared to learn and participate in class.
