extremely significantp < 0.001
In early spring (before flowering) the difference in beneficial arthropod numbers between hedgerow and orchard trees was extremely significant (GLMM, post hoc pairwise test: p < 0.001), while later on, lower significance levels (GLMM, post hoc pairwise tests: p = 0.002 and p = 0.026 during spring and summer, respectively) were obtained.
