Food-web structure in low- and high-dimensional trophic niche spaces.
A question central to modelling 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 interva...

متن کاملRigorous conditions for food-web intervality in high-dimensional trophic niche spaces.
Food webs represent trophic (feeding) interactions in ecosystems. Since the late 1970s, it has been recognized that food-webs have a surprisingly close relationship to interval graphs. One interpretation of food-web intervality is that trophic niche space is low-dimensional, meaning that the trophic character of a species can be expressed by a single or at most a few quantitative traits. In a c...
متن کاملNiche evolution, trophic structure, and species turnover in model food webs.
The features that govern the stability and persistence of species interaction networks, such as food webs, remain elusive, but recent work suggests that the distribution and strength of trophic links play an important role. Potential omnivory-stability relationships have been investigated and debated extensively, but we still have a relatively poor understanding of how levels of omnivory relate...
متن کاملLearning and exploiting low-dimensional structure for efficient holonomic motion planning in high-dimensional spaces
We present a class of methods for optimal holonomic planning in high dimensional spaces that automatically learns and leverages low dimensional structure to efficiently find high quality solutions. These methods are founded on the principle that problems possessing such structure are inherently simple to solve. This is demonstrated by presenting algorithms to solve these problems in time that s...
