The TEI suggests that the number of species on an island is determined by its number of habitats or niches but, with no clear evidence relating species richness to the number of niches however, the TEI has been almost dismissed as a theory in favour of the original ETIB. Here, we show ...
Niche theory as a basic theory in ecology was widely introduced into the research of the social-economical area.The evaluation index system of city niche of Nanning was constructed from three aspects of the economical development,social development and natural ecological environment of urban ecosystem....

It is debated whether species-level differences in ecological strategy, which play a key role in much of coexistence theory, are important in structuring highly diverse communities. We examined the co-occurrence patterns of over 1100 tree species in a 25-hectare Amazonian forest plot in relation ...

Although the classical niche theory is able to address the structure in a concise way, our model, at the cost of introducing more variables to describe niche-based interactions, can reveal a host of fundamental dynamical properties at different timescales. At the ecological timescale, the ...
In contrast, the latter strategy emphasizes the dependence of geographic distances rather than environmental gradients, which is the similar in concept to Hubbell's neutral theory for macroorganisms that stochastic processes and dispersal limitation affect variation in species composition5. Magnetotactic ...
Niche theory is based on the Darwinian view that two co-occurring species must occupy distinct ecological niches. It was Grinnell (1917) who for the first time introduced the terms “niche” and “niche relationships” as a correlation between the performance of a species and resource ...
