Table A6. ANOVA tables for body mass and growth rates of founding meadow voles in manipulated habitat patches early in the season (see Results). 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.
