Table A20. Two-way ANOVA tables for spring density and overwinter survival of meadow vole populations in manipulated habitat patches (Fig. 23). 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.
