Arrows point from predictor to response variables. Positive and negative symbols represent our a priori hypotheses.

Fig 2.
Multi-scale analysis showing the proportion of deviance explained by the different estimates of parasitoid diversity and abundance when using different buffer radii (i.e. 100m, 200m, 500m, 1000m, 1500m and 2000m of radius).
Solid dots represent variables in a given buffer size with a significant effect in the mixed effects models after correction for multiple comparisons using the false discovery rate approach.
Fig 3.
Effect of the proportion of semi-natural habitats at the landscape level on parasitoid species evenness (A) and beta diversity expressed as the LCBD index (B). Only significant effects are plotted. The fitted lines are estimated from the linear effects models, and the points represent model partial residuals based on the visreg package in R. The rugplot shows the distribution of data points along the abscissa axis.
