K. Lin and G. O. Batzli. 2001. The influence of habitat quality
on dispersal, demography, and population dynamics of voles. Ecological
Monographs 71:245-275.
Table A12. ANOVA
tables with repeated measures for mean per capita demographic
variables (in situ recruitment, mortality, immigration, and emigration)
of meadow vole populations in manipulated habitat patches (Fig.
13). 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 only included in tables if it had a significant main
effect or a significant interaction with food or cover. Estimates
of mean demographic values repeated early (weeks 8-14) and late
(weeks 16-22) in the season.
