Generalized linear models for the occurrence frequency of bee species depending on functional traits and landscape variables within 500 m.

Results of generalized linear models with the occurrence frequency of bee species as dependent variables and landscape variables in interaction with functional traits as independent variables. The effect of independent variables was nested in the year to account for interannual. The effect of quadratic term of impervious surface proportion (Impervioussurface2) was higher on cavity-nesting than on soil-nesting bee species, and on non-parasitic than on parasitic bees species. The effect of impervious surface proportion was higher for long-tongued than for short-tongued species.*NS = non significant.P-value significant after the Bonferroni correction has been applied (i.e. p×5) are written in bold.
