The purpose of this project was to determine the nonwinter and winter home ranges of porcupines in a mixed hardwood forest in northern New York and to monitor den activity to determine daily and seasonal changes in den use. Primarily, I a) measured the home range of three radio collared porcupines to determine seasonal and yearly variability; b) monitored den usage to determine time of day of peak activity, seasonal activity differences, and instances of den sharing; and c) observed sexual differences in home range and den usage.

Reproductive experience induces changes in females. Parity-related differences in maternal treatment of offspring can induce enduring changes in offspring. The relationships between maternal experience, early social isolation, and development were explored in rodents in this experiment. Male rats were weaned from multiparous (MP) and primiparous (PP) mothers and placed into isolation or social housing for four weeks. They were then observed in a social-interaction test.
