Y. 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 A3. ANOVA tables for early performance of founding prairie voles (per capita emigration, per capita mortality, proportion settled, and young recruited per female) in manipulated habitat patches (Fig. 6). 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.
