Data for comparison of mass-specific MR of workers and fungus gardens

Mean mass-specific metabolic rate (MR; µl CO2 mg-1 hr-1) for workers and fungal gardens, and results of one sample t-tests comparing worker MR with the mean value for their fungal gardens. Size measured as dry mass. N indicates number of individual workers measured for MR, and the number of individual colonies from which fungal gardens were measured for MR. Means followed by SD in parentheses.
