Coefficients of determination (R2) for each predictor in simultaneous autoregressive regressions in linear and quadratic forms.

“*” = P“**” = P“***” = P“L”, linear predictor“Q”, quadratic predictor.IFO, the index of floristic overlap; MDE, mid-domain effects; MAT, mean annual temperature; MTCQ, mean temperature of the coldest quarter; PET, annual potential evapotranspiration; WI, warmth index; MAP, mean annual precipitation; Rain, rainfall; AI, aridity index; AET, annual actual evapotranspiration; Stemp, temperature seasonality; SPrec, precipitation seasonality; ART, annual range in temperature.Coefficients of determination (R2) for each predictor in simultaneous autoregressive regressions in linear and quadratic forms.
