Table S1 - Climate Effects and Feedback Structure Determining Weed Population Dynamics in a Long-Term Experiment

b maximum finite reproductive rate, a non-linearity coefficient, C equilibrium point, d, e and f coefficients for different effects, r2 coefficient of determination, AICc Akaike information criterion corrected for small sample bias, ΔAICc differences in AICc, likelihood exp(-ΔAICc/2), k number of estimated parameters, Rt = ln(Nt)-ln(Nt-1) realized logarithmic per-capita population growth rate, Xt-1 logarithmic density, NAO = North Atlantic Oscillation Index, TW winter temperature, P precipitation. Models 1, 8, 17 and 22 represent endogenous effects only, the other models concider climate variables as exogenous effects. The most likely model (defined by the lowest AICc) is highlighted in bold.
