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 A15. ANOVA
tables for fitness correlates (body mass of weanlings, body growth
of juveniles, 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.
16). 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 if 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.
