What do you mean by “niche”? Modern ecological theories are not coherent on rhetoric about the niche concept

Acta Oecologica, 2021
Ecologists have long had a “love-hate” relationship with the niche concept. Sometimes referred to as a term best left undefined, the niche concept nonetheless spans ecology.

An exhaustive analysis of heuristic methods for variable selection in ecological niche modeling and species distribution modeling

Ecological Informatics, 2019
Ecological niche models and species distribution models are used in many fields of science. Despite their popularity, only recently have important aspects of the modeling process like model selection been developed.

The Ecological Niche

1974
The environmental conditions that permit a population to survive permanently, and with which this population interacts, today are usually designated as its “ecological niche.” Originally, the term “niche” did not have the same meaning for all ecologists but this need not be considered here. We above define and use it in the sense of Hutchinson (1958).

Conserved Ecological Niches

Science, 1999
In their report “Conservatism of ecological niches in evolutionary time” (20 Aug., p. [1265][1]), A. T. Peterson et al. demonstrate that geographically isolated sister taxa show little differentiation in ecological niche. Their results imply that ecology diverges slowly in allopatry (the geographic isolation of species), and the authors therefore ...

Akaike information criterion should not be a "test" of geographical prediction accuracy in ecological niche modelling

Ecological Informatics, 2019
Model complexity in ecological niche modelling has been recently considered as an important issue that might affect model performance. New methodological developments have implemented the Akaike information criterion (AIC) to capture model complexity in ...

A niche for isotopic ecology

Frontiers in Ecology and the Environment, 2007
Fifty years ago, GE Hutchinson defined the ecological niche as a hypervolume in n-dimensional space with environmental variables as axes. Ecologists have recently developed renewed interest in the concept, and technological advances now allow us to use stable isotope analyses to quantify these niche dimensions. Analogously, we define the isotopic niche

A new null model approach to quantify performance and significance for ecological niche models of species distributions

Journal of Biogeography, 2019
Ecological niche modelling requires robust estimation of model performance and significance, but common evaluation approaches often yield biased estimates. Null models provide a solution but are rarely used in this field.

Analysis of an ecological niche

Mathematical Biosciences, 1987
A model of an ecological niche for different populations of organisms with competition among them is considered using the concepts of food web and niche overlap graph. The descriptive situation is given analytically by means of a strategy game in normal form where the players involved are the respective populations as separate entities.
