New paper from our JenaTron facility:
Bröcher et al. show that reciprocal effects between plants and invertebrate herbivores vary with plant species richness, plant history and soil history.
Herbivores want nutritious plants with soil history, while they reduce plant height in monocultures

Why are we losing arthropod biomass? Because we're losing species? Because of which species we lose? Or because of declining abundances?
