Environmental determinants of territory occupancy.

Model selection summary of 1) the effects of habitat type on frequency of territory occupancy within a radius of 300 m (n = 3000) and 200 m (n = 1388) and 2) of the structural variables (radii: 300 m, n = 2378; 200 m, n = 1153). Shown are the differences between the best and the current model (ΔAIC), the AIC weight of the current model (wi), the number of estimated parameters (K), the model deviance and the territory random effect variance (σ2).*Covariates: mole crickets = mole cricket occurrence probability, dens = soil density, gw = ground water table, veg = vegetation cover, soilt = soil type.
