Abstract

Radioisotope tagging and tracing techniques were used to study home range, movements and diel activity of Scalopus aquaticus. Home range areas of seven moles were calculated after each had been located periodically during periods ranging from 11 months to 3 years. The mean home range area was 0.74 ha; males averaged 1.09 ha, and females 0.28 ha. Diel activity was recorded for 100 complete 24-hr periods. Moles were active at all hours of the day and night, but there were two primary periods of activity, one from 0800 to 1600 hr and one from 2300 to 0400 hr. Periods spent in the nest ranged from a few minutes to 6 hr 25 min and averaged 3 hr 9 min. Periods out of the nest averaged 5 hr 26 min. Each mole used a single nest for inactive periods during cold weather; during warmer weather no specific location was used.
