Determining trophic niche width: a novel approach using stable isotope analysis [PDF]

open access: yes, 2004
1. Although conceptually robust, it has proven difficult to find practical measures of niche width that are simple to obtain, yet provide an adequate descriptor of the ecological position of the population examined. 2.

Modelling the ecological niche from functional traits [PDF]

open access: yesPhilosophical Transactions of the Royal Society B: Biological Sciences, 2010
The niche concept is central to ecology but is often depicted descriptively through observing associations between organisms and habitats. Here, we argue for the importance of mechanistically modelling niches based on functional traits of organisms and explore the possibilities for achieving this through the integration of three theoretical frameworks:

An introduction to niche construction theory [PDF]

open access: yes, 2016
Niche construction refers to the modification of selective environments by organisms. Theoretical and empirical studies of niche construction are increasing in importance as foci in evolutionary ecology.

Genes, culture and agriculture : an example of human niche construction [PDF]

open access: yes, 2012
K. N. Laland was supported by an ERC Advanced Grant (EVOCULTURE).Theory and empirical data from a variety of disciplines strongly imply that recent human history involves extensive gene-culture coevolution, much of it as a direct result of human ...

Little ecological divergence associated with speciation in two African rain forest tree genera [PDF]

open access: yes, 2011
Background The tropical rain forests (TRF) of Africa are the second largest block of this biome after the Amazon and exhibit high levels of plant endemism and diversity. Two main hypotheses have been advanced to explain speciation processes that have led

The probabilistic niche model reveals the niche structure and role of body size in a complex food web. [PDF]

open access: yesPLoS ONE, 2010
The niche model has been widely used to model the structure of complex food webs, and yet the ecological meaning of the single niche dimension has not been explored.

Multilocus phylogeography and ecological niche modeling suggest speciation with gene flow between the two Bamboo Partridges

open access: yesAvian Research, 2021
Background Understanding how species diversify is a long-standing question in biology. The allopatric speciation model is a classic hypothesis to explain the speciation process. This model supposes that there is no gene flow during the divergence process
