Table 1.

Number of resident and unclassified adult male and female prairie voles (Microtus ochrogaster), study area size, and minimum number known alive estimates of population density (adult voles/ha ± SE) at each study site during each year. An adult prairie vole was classified as a resident at a nest if it was captured at least once per week during each of the first 2 weeks of nest trapping, and ≥ 75% of all captures during these 2 weeks were at a single nest site.
