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.

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.

Niche breadth in Bryozoa as a test of competition theory

Nature, 1975
COMPETITION theory predicts that intraspecific and interspecific competition should often have opposite effects on the use of resources by a population, the former increasing, the latter decreasing, the range of resource actually used1,2. Field data supporting these predictions are well known for the interspecific case3,4 but are scarce for the ...

Evolution of Niche Breadth in Populations of Ants

The American Naturalist, 1979
Both the mean forager size and the variability in forager size within colonies of ants are positively correlated with niche breadth on two dimensions-size of foraging area and diet. In colonies that feed on seeds, absolute size of the foragers is related to the size of seeds taken; in colonies that feed on insects, absolute size of the foragers is ...

Likelihood Measures of Niche Breadth and Overlap

Ecology, 1979
Currently 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

Niche Breadth as a Function of Social Dominance

The American Naturalist, 1974
If one species is socially dominant to another, the subordinate usually narrows its niche when they occur together. When one species is dominant in some circumstances and a second in others, both narrow their niches when together. Subordinates usually have a larger fundamental niche than their dominants.

Latitudinal gradient in niche breadth of brachyuran crabs

Global Ecology and Biogeography, 2015
AbstractAimNiche breadth has long been hypothesized to decrease at low latitudes and contribute to global patterns of species diversity. Range size, phylogenetic relatedness and body size also have hypothesized relationships with both latitude and niche breadth, which may further affect niche breadth patterns. Existing terrestrial data are inconclusive

[Niche breadth of Gymnosporangium haraeanum].

Ying yong sheng tai xue bao = The journal of applied ecology, 2002
The resistant difference among different main pear cultivars in Anhui Province to pear rust caused by Gymnosporangium haraeanum was significant. According to disease index and diseased leaves of susceptible cultivars, the niche breadths of hosts were 0.7555 and 0.7951, respectively.
