2 Density Independent mechanisms. Posterior parameter estimates for
responses of density-independent growth rates (ρs) to
standardized environmental covariates (Temp-average summer air
temperature (°C), Snow depth-mean April snow depth (cm), N dep-average
summer nitrogen deposition (g/m2/yr). Points show mean
estimates and error bars show 95% Bayesian credible intervals. We set
wide priors on ρ coefficients (-0.5, 0.5) to allow a 50% change
(increase or decrease) in ρs in response to a given
environmental covariate at each time step and estimates here reflect
posterior sampling across all time steps. Rare species showed weak DI
responses to environmental variables (Fig S7). Estimates are
standardized by treatment as models were run separately for each
treatment, thus the magnitude of parameter estimates and credible
intervals should be compared between species groups within a
treatment but not across treatments (colors).
