Niche Breadth, Resource Availability, and Inference
Ecology, 1982Measures 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.

Geographic patterns of predator niche breadth and prey species richness
Ecological Research, 2015Abstract Most dietary studies on predator species available in the literature are based on single populations, with no meta‐analysis across populations in distinct areas of their range. Here, we performed a systematic review of the available data on the food habits of barn owl ( Tyto alba

How is the rate of climatic-niche evolution related to climatic-niche breadth?
Evolution; international journal of organic evolution, 2013The rate of climatic-niche evolution is important to many research areas in ecology, evolution, and conservation biology, including responses of species to global climate change, spread of invasive species, speciation, biogeography, and patterns of species richness. Previous studies have implied that clades with higher rates of climatic-niche evolution

Area Size and Niche Breadth at Higher Latitudes
1975Fewer plant and animal species, lower production, and a slower rate of decomposition have been considered aspects of the higher latitudes. An increase in niche breadth (Klopfer and MacArthur, 1960; MacArthur, 1969; Willson, 1969) and a decrease in the degree of specialization (Scriber, 1973) have also been observed.

Realizing the niche's breadth: inferring ecological process with species generalism
2010Various ecological processes affect generalist and specialist species differently. By measuring niche breadth in communities, we can infer those processes. Simulation models provided proofs of concept for three analyses that were applied to Carolina Vegetation Survey data.

Evolution of realized niche breadth diversity driven by community dynamics
Ecology LettersAbstract Why many herbivorous insects are host plant specialists, with non‐negligible exceptions, is a conundrum of evolutionary biology, especially because the host plants are not necessarily optimal larval diets. Here, I present a novel model of host plant preference evolution of two insect species.
