T. Michael Anderson, Mark E. Ritchie, and Samuel J. McNaughton. 2007. Rainfall and soils modify plant community response to grazing in Serengeti National Park. Ecology 88:1191–1201.

Appendix A. Site comparisons of mean (± SE) soil available nitrogen (N), soil available phosphorus (P), soil N:P ratios (N:P), grazed standing biomass (G Bio), ungrazed standing biomass (UG Bio), and grazing intensity (G). Main effects of site are not significantly different (α = 0.05) for values followed by the same letter within a column (significance level was bon-ferroni adjusted for multiple comparisons).  The value for G at BAL was not included because a fire at the site modified standing biomass such that G Bio was > UG Bio.
