The intermediate disturbance hypothesis does not explain fire and diversity pattern in fynbos
D.W. Schwilk, Jon E. Keeley, W. Bond
1997, Plant Ecology (132) 77-84
The intermediate disturbance hypothesis is a widely accepted generalization regarding patterns of species diversity, but may not hold true where fire is the disturbance. In the Mediterranean-climate shrublands of South Africa, called fynbos, fire is the most importance disturbance and a controlling factor in community dynamics. The intermediate disturbance hypothesis...
