A summary of the GLMMs used to test the importance of treatment (cushion-open) and physical factors on estimates of alpine plant community composition.

Richness is the number of species, abundance the total number of individuals, and diversity the Simpson’s index. Tukey post hoc contrasts were used to assess categorical, within factor level differences (i.e. C = cushion or Op = open) and regressions used for continuous (+ indicates significant positive relationship). The degrees of freedom listed refer to the specific factor (DFmodel = 14). Bold denotes significance at p
