Pathogens and herbivores differ in key life history characteristics, and we expected that these might drive differences in terminology, patterns, and hypotheses in the published literature.
Figure 1 from our paper showing biological differences in life-history traits (bold text) across above- and belowground compartments for pathogenic and herbivorous consumer groups. some consumers (i.e., leaf miners and parasitic nematodes) exhibit traits that span both categories. The bold text for pathogens reads: "span a wider taxonomic breadth (viruses, bacteria, and multi-cellular eukaryotes), limited host choice, may require vectors, fast reproduction". The text for herbivores reads: "span a narrower taxonomic breadth (restricted to animals), consumed by predators, movement, range in body size, host choice."

The effects of different drivers and their scale-dependency operated through different mechanisms:
The mechanisms underlying the effects of the study environmental drivers on local diversity at small (10 m2 plots) and larger (100 m2 plots) fine-grain sizes (a) and on β-diversity—the scaling factor among the two scales (b). https://doi.org/10.1002/ece3.70941

We investigated how climate, soil properties, abiotic disturbance, and land use influence plant diversity across two fine grain sizes (10 vs 100 m2) in various grassland types in Ukraine. The strength of most of the effects of these drivers varied between spatial scales, affecting β-diversity.
Scale-dependent effects of environmental drivers on species richness and evenness at small (10 m2) and larger (100 m2) fine-grain plots. Points show the standardized effect sizes of each environmental driver (marked by colors of points) on the diversity measures at 10 m2 scale (x-axis) compared to 100 m2 (y-axis). The solid gray line indicates the 1: 1 line expected if effect sizes were not scale-dependent. Points above and below this line indicate effect sizes that are larger or smaller, respectively, as grain size increases. https://doi.org/10.1002/ece3.70941
