Regression coefficients, adjusted standard error, values of t or z (for full averaged model) and p values from linear regression models between wintering greylag geese (log-transformed) as dependent variable and year, surface of crops and January temperatures as predictors.

1z value; 2 t value Only best sub-models are represented. When there is more than one sub-model with ΔAIC < 2 (see S2 Table) full model averaged coefficients are shown (see methods). Sample sizes vary greatly because of missing data for predictor variables, especially for land use.
