Appendix F. The effect of community manipulation and site on dung beetle community attributes.
Table F1. Outputs from generalized least squares models (gls) to assess the effect of community manipulation (opening time: 12 or 24 hours, and opening period: day or night, that plots were accessible for beetle colonization) and site (Clay, Sand 1, Sand 2) on dung beetle community attributes. Significance was assessed by Chi-squared likelihood ratio tests (LRT) using single term deletions.
