About this item

In Green Equilibrium, award-winning field biologist Christopher Wills explains the rules by which ecosystems thrive, shining light on a set of ecological balancing acts that he calls green equilibria, rules which keep our world vibrant, verdant, and ecologically intact. To explain the idea of green equilibrium, Wills draws on a fascinating range of examples, including coral reefs off the densely populated Philippines, the isolated and thickly forested valleys of Papua New Guinea, the changing Himalayan kingdom of Bhutan, and a Californian ranch being allowed to return to a wild state. Wills travels to Guyanas rainforests and savannahs, for instance, to provide startling vignettes of ecological processes in action. Among other topics, he highlights the astonishing snake-head mimicry that swallowtail caterpillars use to scare off predators, the symbiotic relationship between the exceedingly rare Golden Poison-Dart Frog and the tank bromeliad plant, and the invisible world of pathogens and parasites that helps to drive diversity.
