Interactions connect the units of ecological systems, forming networks. Individual-based
networks characterize variation in niches among individuals within populations. These …

Network approaches to ecological questions have been increasingly used, particularly in
recent decades. The abstraction of ecological systems–such as communities–through …

Vertebrates harbour diverse communities of symbiotic gut microbes. Host diet is known to
alter microbiota composition, implying that dietary treatments might alleviate diseases …

Ecology Letters (2011) 14: 948–958 Abstract Many generalist populations are composed of
specialised individuals, whose niches are small subsets of the population niche. This …

Individuals often differ in what they do. This has been recognised since antiquity.
Nevertheless, the ecological and evolutionary significance of such variation is attracting …

A species's niche width reflects a balance between the diversifying effects of intraspecific
competition and the constraining effects of interspecific competition. This balance shifts …

Networks of species interactions underpin numerous ecosystem processes, but
comprehensively sampling these interactions is difficult. Interactions intrinsically vary across …

In the last decade, an increasing number of papers testifies a renewed interest in the topic of
individual specialization in resource use and its implication at higher levels of ecological …

Speciation can be viewed as a continuum, potentially divisible into several states:(1)
continuous variation within panmictic populations,(2) partially discontinuous variation with …

The impact of human activity is evident in the depletion of fish populations worldwide. This
being the case, there is an urgent need to discover the true biodiversity of the world before …
