Abstract
Home range and movement data of nutria and beaver were collected using radio telemetry techniques from 16 December 2000 through 7 November 2001. A total of 14 nutria and three beaver were radio collared. Home range was calculated for eight nutria, four females and four males, and two beaver, one female and one male. The overall mean home range of the nutria was 2.74 ha. The mean home range of the four female nutria was 1.61 ha and 3.88 ha for the four male nutria. No significant difference in home range size was detected between females and males (t = 1.26, P > 0.05). The mean maximum linear distance traveled daily by the eight nutria was 276.46 m; females averaged 217.30 m and males averaged 335.62 m. No significant difference was found between mean maximum linear distance traveled between females and males (t = 1.35, P > 0.05). The mean home range of the two beaver was 3.72 ha. The mean maximum linear distance traveled by the three beaver was 853.28 m.
