Play Behavior And The Development Of Boldness And Caution In Juvenile Belding’S Ground Squirrels (Urocitellus Beldingi), Madelene Shehan
Play Behavior And The Development Of Boldness And Caution In Juvenile Belding’S Ground Squirrels (Urocitellus Beldingi), Madelene Shehan
Master's Theses
The ubiquity of play among juvenile mammals suggests it provides adaptive benefits, potentially through influences on the development of temperament in young animals. Juvenile Belding’s ground squirrels (Urocitellus beldingi) must balance competing demands for boldness and caution imposed by the fundamental trade-off between their short active season and their vulnerability to predation. In this study, I evaluated whether play helps to facilitate the development of an appropriate balance between boldness and caution in juvenile U. beldingi.I observed the play behavior of juvenile U. beldingiand conducted flight-initiation distance tests to measure boldness-caution at the beginning and toward …
The Effects Of Predation Risk And Thermoregulation Cost On The Foraging Behavior Of The Eastern Grey Squirrel (Sciurus Carolinensis), Anne E. Collier
The Effects Of Predation Risk And Thermoregulation Cost On The Foraging Behavior Of The Eastern Grey Squirrel (Sciurus Carolinensis), Anne E. Collier
Senior Theses and Projects
In this study, the effects of predation risk and thermoregulation cost on the foraging behavior of the urban eastern gray squirrel (Sciurus carolinensis) were examined. There were two objectives. The first was to determine if either thermoregulation cost or predation risk had a more significant effect on foraging behavior. The second was to find out if foliar cover or distance to refuge was a more important cue of predation risk. To accomplish these goals, giving-up density and temperature data were collected at feeding trays both under the canopy and outside of the canopy at two deciduous trees and …
