Standardization of Microtus Home Range Calculation

Abstract
A population of Microtus pennsylvanicus of high density, one of medium density, and one of low density were live-trapped in the summers of 1960 to 1962. Home ranges were calculated by several methods (minimum boundary, exclusive boundary, and inclusive boundary), and differences between the results of the three methods are presented. Individual ranges were determined by the number of different stations at which the vole was trapped. This method eliminates the factor of trap-habituation that appears when ranges are determined by the number of captures, and is conducive to better intra- and interspecific comparisons.
