Modeling Ecological Niches

2011
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 ...

Physiology, Ecological Niches and Species Distribution

Ecosystems, 2009
Although 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.

Conservatism of Ecological Niches in Evolutionary Time

Science, 1999
Theory predicts low niche differentiation between species over evolutionary time scales, but little empirical evidence is available. Reciprocal geographic predictions based on ecological niche models of sister taxon pairs of birds, mammals, and butterflies in southern Mexico indicate niche conservatism over several million years of independent ...

Denitrification: ecological niches, competition and survival

Antonie van Leeuwenhoek, 1983
Organisms 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.

Environmental fluctuations and the theory of the ecological niche

Journal of Theoretical Biology, 1978
May and MacArthur proposed that a limit to the permissible degree of similarity between competing species might result from the resilience of any of the species to environmental fluctuations dropping dramatically as the differences between the competitors were reduced. For certain idealized models of species competing for a single type of resource this

Representing Ecological Niches in a Conceptual Model

2004
The niche concept has been recognised as a fundamental notion in biological and business systems, amongst others. Existing data models do not have adequate primitives that faithfully represent ecological niches for geographical information systems.

The Niche-Center Relationship in Ecological Niche Modeling

The niche-center relationship posits that organisms’ fitness is highest at the center of their fundamental ecological niche, an assumption often implicit in ecological niche modeling. Nevertheless, empirical support for the niche-center relationship at the species level is often inconsistent, potentially due to confounding factors such as biotic ...

Ecological Niche Modeling of Acanthamoeba in Türkiye

EcoHealth
Acanthamoeba, is an opportunistic pathogenic organism with a global distribution and the potential to cause severe human infections. This study primarily aimed to identify the environmental factors influencing the distribution of Acanthamoeba by analyzing various bioclimatic and topographic variables, and to predict their potential current and future ...
