Effects of a Subminiature Radiocollar on Activity of Free-Living White-Footed Mice

摘要

The effects of a subminiature (1.1 g) radiocollar on activity of free-living Peromyscus leucopus were examined by comparing recapture frequency, persistence, apparent reproduction, body weight, and ranging activity of 43 collared and 304 uncollared mice. Although some differences between collar treatment groups were noted for most measures, no significant deleterious effects of wearing the radiocollar were detected. Collared juveniles weighing from 12 to 16 g appeared to grow and mature similarly relative to uncollared juveniles. The results suggest that this radiocollar-package can be used to provide reliable information about the natural acitivity of both immature and adult P. leucopus. 14 references, 2 tables.
