Buffer zones for biodiversity of plants and arthropods: is there a compromise on width?
Model 2 Linear mixed model for comparing width of buffers, distance from hedge and sampling period. The model include the effect of field, width of buffers, distance from hedge and sampling period as well as 2- and 3-way interactions between width of buffers, distance from hedge and sampling period as fixed effects. The effect of both types of whole-plot, sub-plots and residual are includes as random effects.
