Despite the apparent hyperabundance of green foliage in evergreen tropical forests, soil fertility can affect the resource base available to strict and facultative folivores, which are often highly selective and limited by the amount and quality of palatable leaves (Ganzhorn 1980, Peres 1997b, Gupta and Chivers 1999) Wonders of the Rain Forest..
