A field study of activity patterns of thomomys bottae


, : A field study of activity patterns of thomomys bottae. Journal of Mammalogy 65(1): 76-84

Activity of pocket gophers, T. bottae, which were tagged with radioactive gold wires, was distributed throughout the 24 h day, but was significantly more common between 1600-2000 h. Pocket gophers spent 15 h/day in underground nest chambers at depths of 40 cm. The remainder of the day was spent in activities in the general burrow system at depths < 20 cm. The duration of resting and activity bouts averaged 40 and 26 min, respectively, but varied with time of day. No relationship between timing or location of activities and soil or air temperature was evident. Mean burrow system area was 107 m2, but 90% of all activity occurred within an area of 48 m2. Gophers moved within their burrows at rates of 1.1 m/min active (< 600 m/day) and did not burrow extensively.
