Decomposition of effects from mediation analysis for the effects of temperature on N_{liceA_std} that are direct or mediated through IP, taking into account interaction between T and IP

Effect	Estimate	SE	Interpretation
Pure direct effect	0.007	0.060	The increase in log(NliceA) brought about by a 1 SD increase in T with IP held constant at an average T
Total direct effect	0.156	0.051**	The increase in log(NliceA) brought about by a 1 SD increase in T with IP held constant at the level resulting from that 1 SD increase in T
Pure indirect effect	0.418	0.047***	The increase in log(NliceA) brought about by increasing IP by the amount that would result from a 1 SD increase in T while holding T constant at an average T
Total indirect effect	0.567	0.073***	The increase in log(NliceA) brought about by increasing IP by an amount that would result from 1 SD increase in T while holding T constant at the level resulting from that 1 SD increase in T
% of total effect mediated	0.784		Based on a total effect of 0.723

*P < 0.05, **P < 0.01, ***P < 0.001
