   Notes: The mean frequency-proportion of dominant single species in treatments. We only included incidences where mean species frequency exceeded 0.15 of total frequency sum of all species. Also provided is the mean and confidence range (95%) of measured yield from defoliation over the study period (for microcosms that were cut).
