  1. Significant P values < 0.05 are in bold
  2. E estimate, SE standard error, CI confidence interval, LL lower bound at 95% level of confidence, UL upper bound at 95% level of confidence, P values. R2 represent the coefficient of determination for each selected model which does not include all explanatory variables. Models related to spatial connectivity (degree and betweenness) are not significant (null models are shown)
