Competition and the niche; limiting similarity and differential niche overlap
1984In the previous chapter, competition was shown to influence both the size of the niche and the degree of niche overlap between species. The ideas discussed there lead to an interesting question. If no two species can occupy the same niche indefinitely when resources are limiting, then how similar can two species be and still coexist?

Some Comments on Measuring Niche Overlap
Ecology, 1980This article discusses the usefulness of niche overlap and niche overlap measures in studying competition. It is argued that (1) neither niche overlap nor niche overlap measures can be used to estimate the intensity of competition, but (2) niche overlap can be used to determine the relative amounts of inter— and intraspecific competition, while niche ...

On the statistical analysis of niche overlap data
Canadian Journal of Zoology, 1990It has recently been suggested that problems with the statistical analysis of niche overlap data can be overcome by computing overlaps between randomly paired individuals. This allows a test for temporal changes in the overlap between two populations. In this paper, it is suggested that this test relies too heavily on random pairing. It is argued that

Oikos, 1987
Questions about the relation between niche overlap measured along single niche dimensions and total niche overlap, and about the relation between overlap and competition, have long troubled ecologists. In this note it is shown that competition may exist even though overall niche overlap in a multidimensional niche space is zero.
