on dispersal, demography, and population dynamics of voles. Ecological
Monographs 71:245-275.
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.
