The little things count: Termites hold the reins in African savanna

Research by Robert M. Pringle and Todd M. Palmer reveals that termite mounds significantly enhance plant and animal productivity at local levels, while their even distribution maximizes ecosystem-wide biomass. The ordered distribution of these mounds creates an optimized network of plant and animal output.
