Food webs and the dimensionality of trophic niche space.
If the trophic niche of a kind of organism is a connected region in niche space, then it is possible for trophic niche overlaps to be described in a one-dimensional niche space if and only if the trophic niche overlap graph is an interval graph. An analysis of 30 food webs, using the combinatorial theory of interval graphs, suggests that a niche space of dimension 1 suffices, with unexpectedly ...
متن کاملHow trophic interaction strength depends on traits: A conceptual framework for representing multidimensional trophic niche spaces
A key problem in community ecology is to understand how individuallevel traits give rise to population-level trophic interactions. Here we propose a synthetic framework based on ecological considerations to address this question systematically. We derive a general functional form for the dependence of trophic interaction coefficients on trophically relevant quantitative traits of consumers and ...
متن کاملFood-web intervality in low- and high-dimensional trophic niche spaces
A question central to modeling and, ultimately, managing food webs concerns the dimensionality of trophic niche space, that is, the number of independent traits relevant for determining consumer-resource links. Food-web topologies can often be interpreted by assuming resource traits to be specified by points along a line and each consumer’s diet to be given by resources contained in an interval...
متن کاملMapping the niche space of soil microorganisms using taxonomy and traits.
The biodiversity of microbial communities has important implications for the stability and functioning of ecosystem processes. Yet, very little is known about the environmental factors that define the microbial niche and how this influences the composition and activity of microbial communities. In this study, we derived niche parameters from physiological response curves that quantified microbi...
