Fig 4: Regression analysis of the number of pollen tubes on stigmas as a function of environmental pollinator species richness. The coloured lines and areas respectively indicate the estimated relationship and its confidence intervals with Generalised linear mixed models, see methods for further details.
Table 1: Output of different Generalised linear mixed models of pollinator species richness, Connectance, individual pollinator degree. Final models were selected through backward stepwise selection using AIC criterion. ΔAIC reports the difference in AIC values between full and final models. βi: regression coefficient of a given variable; χ2: chi square values; df: degrees of freedom. P value stands for statistical significance after log likelihood ratio test, and it is in bold if below 0.05. The regression coefficients for each of the three pollinator species considered in interaction with the predictors in the individual pollinator degree model correspond to a - Xylocopa fenestrata, b -Lasioglossum albescens , and c - Braunsapis picitarsis.
