On 3% of the Earth's surface, the rain forest is the habitat for half our animal species, even 80% of insects. So its wildlife is most competitive, like the birds of paradise's mating, and specialized with unique relationships of predation, parasitism etc. For plants, the quest for light is key to stratification, paralleled by interacting animals eating fruits, leaves and other animals. Even the jungle cacophony is stratified. On the soil, recycling specialist like fungi restart the cycle of life. In Central Africa even herds of elephants specialize in following self-made forest paths. Written by
