Tree-grass interactions in Savannas
TL;DR: Understanding of the widely observed increase in tree biomass following introduction of commercial ranching into savannas requires inclusion of interactions among browsers, grazers, and fires, and their effects on tree recruitment.
Journal ArticleDOI

TL;DR: New research is needed that considers the full ensemble of processes and feedbacks, for a range of biophysical and social systems, to better understand and manage the dynamics of the relationship between humans and the ecosystems on which they rely.
Journal ArticleDOI
