Mammalian herbivory indirectly shapes savanna arthropod communities but only at very low or high levels

Journal of Animal Ecology, EarlyView.
This study investigates how large mammalian herbivores shape arthropod communities in African savannas, using a broad gradient of herbivory types and intensities to assess these effects under real‐world, non‐experimental conditions. Abstract Savanna ecosystems support unique biodiversity and provide livelihoods for millions of people.
