Farmers' Interest in Nature and Its Relation to Biodiversity in Arable Fields

Table 1

Results from stepwise multiple regressions with the biodiversity index and species richness of different organism groups as dependent variables. 𝑃-values are presented both for the full models (𝑝-model) and single independent variables (𝑝 var). 𝑅² values and 𝐹-values are presented for the full models. The direction of the effect is indicated by the +/− column.
