Table 1. Factors affecting the rates of change of genetic and phenotypic variance during the first 250-generations in a constantly-fluctuating environment.

Response	Predictor	% Var.	P-value
Variable		Explained
dVP/dt	Network Size	57	<2.2e−16
	dE/dt	8	<2.2e−16
	n * dE/dt	4	2.29e−7
dVG/dt	Network Size	16	<2.2e−16
	dE/dt	2	0.013
	n * dE/dt	7	0.0001

dV_P/dt is the rate of change of phenotypic variance; dV_G/dt is the rate of change of genetic variance. n refers to network size; dE/dt is the rate of environmental change.
