Data from: Parasite resource manipulation drives bimodal variation in infection duration

Anieke Van Leeuwen, Sarah A. Budischak, Andrea L. Graham & Clayton E. Cressler
Over a billion people on earth are infected with helminth parasites and show remarkable variation in parasite burden and chronicity. These parasite distributions are captured well by classic statistics, such as the negative binomial distribution. But the within-host processes underlying this variation are not well understood. In this study, we explain variation in macroparasite infection outcomes on the basis of resource flows within hosts. Resource flows realize the interactions between parasites and host immunity and...

The past, present, and future of herbivore impacts on savanna vegetation

Ann Carla Staver, Joel Abraham, Gareth Hempson, Allison Karp & J Faith
1) Herbivory is a key process structuring vegetation in savannas, especially in Africa where large mammal herbivore communities remain intact. Exclusion experiments consistently show that herbivores impact savanna vegetation, but effect size variation has resisted explanation, limiting our understanding of the past, present, and future roles of herbivory in savanna ecosystems. 2) Synthesis of vegetation responses to herbivore exclusion shows that herbivory decreased grass abundance by 57.0% and tree abundance by 30.6% across African savannas....
