摘要：
Home range size was investigated in wild house mice living in outdoor enclosures using powder-tracking and radio-tracking. We obtained 19 home-range estimates for juvenile mice using powder-tracking, and 43 estimates for adults using both techniques. juvenile males, juvenile females and adult females did not differ in home-range size, but ranges of adult males were larger than those of the other three groups. Changes in home-range size were examined with trend analysis using body weight as an indicator of age. Home ranges of males had a positive linear relationship with body weight, whereas home ranges of females fit a negative quadratic trend with body weight. Population density was not an accurate predictor of home-range size of all mice, nor was adult-male density a predictor of adult-male home-range size. Powder-tracking and radio-tracking yielded equal estimates of home ranges for adult mice.
