on dispersal, demography, and population dynamics of voles. Ecological
Monographs 71:245-275.
Table A16. ANOVA
tables for fitness correlates (body mass of juvenile recruits,
body growth of juveniles, and young recruited per adult female
with repeated measures and young survived to adult size without
repeated measures) of prairie vole populations in manipulated
habitat patches (Fig.17). 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 demographic values
repeated early (weeks 8-14) and late (weeks 16-22) in the season
for three fitness correlates.
