The Effect Of Developmental Temperature On Morphology, Energy Metabolism, Growth Hormone And Thyroid Stimulating Hormone In Long-Evans Rats, Dana Elizabeth Quinn
Dissertations and Theses
Long-Evans rats were raised from birth to eight weeks of age at 5°C, 20°C and 30°C. Blood was taken from animals two to eight weeks of age and assayed for growth hormone and thyroid stimulating hormone. The 30°C reared rats were found to have the longest ear, tail and hind limbs, followed by the 20°C reared rats. The 5°C rats were found to have the shortest ear, tail and hind limb. The 30°C and 5°C reared rats were found to have similar masses at the termination of the experiment. The 20°C reared rats had the smallest mass. Differences in size …

Social Behavior In A Group Of Captive Bobcats : A Study In The Sociability Of Felids, Lon W. House
Dissertations and Theses
A group of four captive bobcats (Felis rufus), two males and two females, was observed for 102.67 hours over the period of one year. A pilot study was conducted consisting of a minimum of three separate observations for each daylight hour. The remaining observations were concentrated during the early morning hours immediately after feeding, the time of maximum activity and social interaction.
