Matings Systems and the Evolution of Niche Breadth

The American Naturalist, 1999
Several theoretical studies of niche breadth evolution have shown that niche breadth expansion can only occur under a limited set of conditions. These studies have assumed that mating pairs form at random within spatial subpopulations. I show here that nonrandom mating within spatial subpopulations can greatly alter niche breadth evolution.

The Latitudinal Gradient in Niche Breadth: Concepts and Evidence

The American Naturalist, 2004
We examine Robert MacArthur's hypothesis that niche breadth is positively associated with latitude (the latitude-niche breadth hypothesis). This idea has been influential and long standing, yet no studies have evaluated its generality or the validity of its assumptions.

Climatic‐niche breadth, niche position, and speciation in lizards and snakes

Journal of Biogeography
AbstractAimThe climatic niche is associated with diversification in many groups of animals and plants. However, the relationships between climatic‐niche breadth evolution, climatic‐niche position evolution, and speciation remain underexplored. It is particularly unclear whether changes in climatic‐niche breadth are related to diversification. We tested

On the Measurement of Niche Breadth and Overlap

Ecology, 1971
Measures of niche breadth and overlap that depend on the distribution of individual among resource states (ecological categories) should be independent of the relative abundance of the species and of the number of resource states considered. Such measures should also take into account the degree of distinctness of the resource states from the point of ...

Using niche breadth theory to explain generalization in mutualisms

Ecology, 2018
AbstractFor a mutualism to remain evolutionarily stable, theory predicts that mutualists should limit their associations to high‐quality partners. However, most mutualists either simultaneously or sequentially associate with multiple partners that confer the same type of reward.

NICHE — Programs for Niche Breadth, Overlap and Hypervolumes

1991
The concept of niche involves two complementary aspects, one related to the hypervolume occupied by a species or a community in the ecological space (e.g. Hutchinson 1957, 1978; Feoli, Ganis and Woldu 1988) and the other related to the pattern of resources exploitation and competition (e.g.
