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.

The ecological niche of the consortium " Pelochromatium roseum "

Archives of Microbiology, 1998
A dense accumulation of the phototrophic consortium "Pelochromatium roseum" in a small, eutrophic, freshwater lake (Dagowsee, Brandenburg, Germany) was investigated. Within the chemocline, the number of epibionts of the consortia represented up to 19% of the total number of bacteria. Per "P. roseum" a mean value of 20 epibionts was determined.

Major challenges for correlational ecological niche model projections to future climate conditions

Annals of the New York Academy of Sciences, 2018
Species‐level forecasts of distributional potential and likely distributional shifts, in the face of changing climates, have become popular in the literature in the past 20 years. Many refinements have been made to the methodology over the years, and the

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.

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 ...

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

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 ...
