Table A21. Tables for two-way ANOVA with repeated measures for distance moved between trapping sessions of prairie vole and meadow vole populations in manipulated habitat patches (see Discussion). 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 in tables because it had no significant effects. Estimates of mean movements repeated early (weeks 8-14) and late (weeks 16-22) in the season.
