Table A7. Two-way ANOVAs with repeated measures for density and proportion of prairie vole populations in manipulated habitat patches (Fig. 8). Experimental manipulations included mowing (cover) and supplemental feeding (food) in a 2 X 2 factorial design with 4 replicates. Elevation (2 replicates upslope and 2 downslope) used as a third factor, but not included in tables because it had no significant effects. Trapping of voles repeated at biweekly intervals for 22 weeks.
