Figure 2From: A spatially-explicit count data regression for modeling the density of forest cockchafer (Melolontha hippocastani) larvae in the Hessian Ried (Germany) Model effects (Eq. 8.5) of distance to water table ( DWT ) (A) and clay thickness ( CTH ) (B) on the mean of the conditional negative binomial distribution for describing larva density per m 2 . Dashed lines mark the 95% confidence intervals of the model effects.Back to article page
