Trees have overlapping potential niches that extend beyond their realized niches
ScienceTree species appear to prefer distinct climatic conditions, but the true nature of these preferences is obscured by species interactions and dispersal, which limit species’ ranges. We quantified realized and potential thermal niches of 188 North American tree species to conduct a continental-scale test of the architecture of niches. We found strong and

Overlap and partitioning of the ecological and isotopic niches
Oikos, 2010Recently, it was proposed that stable isotope patterns can be used to quantify the width of the ecological niche of animals. However, the potential effects of habitat use on isotopic patterns of consumers have not been fully explored and consequently isotopic patterns may yield deceptive estimates of niche width.

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?

Niche Overlaps and the Evolution of Competitive Interactions
1989Several theoretical studies have suggested that the nature of interactions between species effect the structure of communities. Most of these studies were based on the analysis of an interaction matrix A, and its stability properties. The elements of this matrix describe the interactions between species: diagonal elements α ii describe the effect of ...

Likelihood Measures of Niche Breadth and Overlap
Ecology, 1979Currently used niche measures of overlap and breadth are shown to be inappropriate for analyzing field data. Previously proposed measures assume resources are equally available, but this assumption is unwarranted in field studies. Comparisons of different measures of either breadth or overlap are also not valid. A measure of niche breadth is derived by

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
