Abstract: The actual value of a resource state, or alternatively, a resource state′s position along the resource spectrum, is often neglected by empirical niche metric formulae. To remedy this defect, a different niche separation metric formula is needed for measuring species niche dissimilarity. From this approach, the actual value of the resource state is incorporated as a distance from the state to the theoretical niche center in n-dimensional hyperspace. An example from Cryptocarya community in the Dinghushan Nature Reserve, South China reveals niche sparation between species in utilizing soil resources
