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 A8. Three-way
ANOVA tables with repeated measures for density and proportion
of meadow vole populations in manipulated habitat patches (Fig.
9). 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. Trapping of voles repeated at biweekly intervals for 22
weeks.
