Philip G. Hahn and John L. Orrock. 2015. Spatial arrangement of canopy structure and land-use history alter the effect that herbivores have on plant growth. Ecosphere 6:193. http://dx.doi.org/10.1890/es15-00036.1
Appendix B. Analysis of the growth of plants within full exclosures.
Table B1. ANOVA table for the analysis of plants grown within full herbivore exclosures. Values are F values. We used a four-way mixed-model ANOVA with land-use history, overstory tree thinning, thinning in the adjacent patch, and distance from the edge as fixed effects. We used a four-way ANOVA in order to focus on potential main effects of land-use history and canopy structure, in addition to potential edges effects.
