Abstract
We investigated measurements of home-range size of the American marten (Martes americana) (based on telemetry and the minimum-convex-polygon methods) from the literature for sources of variation. Male home-range size varied significantly among study sites, but female home ranges did not. Home ranges of males were larger than those of females. Mean home-range size did not vary significantly with number of radio locations, or with sampling interval. Sample duration was a significant source of variation in home-range size. Home-range size was not significantly correlated with geographic latitude or with mean annual temperature range. Between-site differences emphasize the need for identifying ecological factors that may explain variability in sizes of marten home ranges.
