Table 2. General Linear Model results testing for the ability of the coefficient of variation (CV) of the explanatory variables over the three sample times to predict the CV of the DEA and mass-standardized (m-s) DEA rates over the same sample times.

Explanatory variable	CoefficientCV of DEA	p 1 CV of DEA	Coefficient CV of m-s DEA	p 1 CV of m-s DEA
Functional diversity2	−0.02	0.24	−0.06	<0.01

Model coefficients and p-values are reported.

¹Bold p-values indicate significance (p<0.05).

²A CV cannot be calculated for functional diversity since it was not measured at each sample date.

³The CV of MBC is not included as an independent variable in the CV of mass-standardized DEA rates model because it is part of the mass-standardized DEA calculation.
