on dispersal, demography, and population dynamics of voles. Ecological
Monographs 71:245-275.
Table A13. ANOVA
tables with repeated measures for mean per capita net recruitment
(births - deaths), mean per capita net movement (immigration -
emigration), and mean per capita population growth (births - deaths
+ immigration - emigration) of prairie vole populations in manipulated
habitat patches (Fig. 14). 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.
