Abstract Impact assessments increasingly rely on models to project the potential impacts of climate change on species distributions. Ecological niche models have become established as an efficient and widely used method for interpolating (and sometimes extrapolating) species’ distributions.

This chapter explains how environmental data can be used to create models that characterize species’ ecological niches in environmental space. It introduces a model, which is a function constructed by means of data analysis for the purpose of approximating the true relationship (that is, the niche) in the form of the function f linking the environment ...

Ecological niche differentiation among anammox bacteria
Water Research, 2020Anaerobic ammonium oxidizing (anammox) bacteria can directly convert ammonium and nitrite to nitrogen gas anaerobically and were responsible for a substantial part of the fixed nitrogen loss and re-oxidation of nitrite to nitrate in freshwater and marine ecosystems.

Physiology, Ecological Niches and Species Distribution
Ecosystems, 2009Although many studies have debated the theoretical links between physiology, ecological niches and species distribution, few studies have provided evidence for a tight empirical coupling between these concepts at a macroecological scale. We used an ecophysiological model to assess the fundamental niche of a key-structural marine species.

Denitrification: ecological niches, competition and survival
Antonie van Leeuwenhoek, 1983Organisms with the denitrification capacity are widely distributed and in high density in nature. It is not well understood why they are so successful. A survey of denitrifying enzyme content of various habitats is presented which indicates a role of carbon and oxygen, but not nitrate, in affecting denitrifier populations.

Ecological niche models of invasive seaweeds
Journal of Phycology, 2015Ecological niche models (ENMs) are commonly used to calculate habitat suitability from species’ occurrence and macroecological data. In invasive species biology, ENMs can be applied to anticipate whether invasive species are likely to establish in an area, to identify critical routes and arrival points, to build risk maps and to predict the extent of ...

Niche, habitat, and related ecological concepts
Acta Biotheoretica, 1975Darwin's phrase “place in natural economy”, andSpencer's term “correspondence” can be regarded as first attempts to express the organism-environment relationships. The same concept has more recently been approached from the point of view of (1) life-form, (2) external activities, and (3) habitat. Though all these points are interlocking, they have been

Discourse Ecology and Knowledge Niches
Science, Technology, & Human Values, 2015In this article, we investigate Internet discourses that capture Canadians’ perceptions of the risk of radiation from the 2011 Fukushima nuclear incident. We consider these online discourses of radiation risk in the context of recent Internet-based theories that explore ecological models of communication, and we take a discourse approach to our ...

Bryophytes and ecological niche theory
Botanical Journal of the Linnean Society, 1990Classical niche theory, particularly in terms of competitive exclusion, does not appear to apply as well to bryophytes as to other organisms. Bryophyte communities, as well as those of other plants and of animals, can be thought of in terms of individual species each utilizing particular portions of various resource or habitat continua.
