Niche Breadth, Resource Availability, and Inference
Eric P. Smith · Ecology · 1982
Measures of niche breadth are discussed in relation to the distance between the resource use distribution and the resource availability distribution. Methods are developed for comparing breadth measures, testing a breadth measure equal to a given value, and for estimating confidence intervals. A new breadth measure is presented which has good statistical properties and is related to some commonly used niche overlap measures. See full-text article at JSTOR
