Fig. 1: Distribution of site-level correlations.
From: Insect decline in forests depends on species’ traits and may be mitigated by management
Shown is Pearson’s r between year and the respective community response in species richness (left column), abundance (middle column), and biomass (right column) for a–c the total insect community, d–f herbivores, g–i myceto-detritivores, j–l omnivores, and m–o carnivores. Bold vertical lines indicate average correlations (95% in shaded polygons). Correlations were negative on average with the exception of positive average correlations for herbivore species richness and abundance, while for total abundance and herbivore biomass 95% CI overlapped with null. Dashed vertical lines mark null with negative values indicating sites with declining and positive values sites with increasing community responses over time. Numerical details are reported in Supplementary Table 2. Percentages in each panel give the proportion of sites with negative (left) and positive (right) correlations.
