Many different concepts have been used to describe species' roles in food webs (ie, the
ways in which species participate in their communities as consumers and resources). As …

Compartments in food webs are subgroups of taxa in which many strong interactions occur
within the subgroups and few weak interactions occur between the subgroups. Theoretically …

To facilitate the analysis of real and simulated data on groups, organizations and societies,
tools and measures are needed that can handle relational or network data that is multi …

Many ecological indicators have been proposed to detect and describe the effects of fishing
on marine ecosystems, but few have been evaluated formally. Here, simulation models of …

Group I metabotropic glutamate receptors (consisting of mGluR1 and mGluR5) are G-protein-
coupled neurotransmitter receptors that are found in the perisynaptic region of the …

We present a graph theoretic model of analysing food web structure called regular
equivalence. Regular equivalence is a method for partitioning the species in a food web into …

Weighted flow networks are structures that arise naturally when analyzing complex systems.
The countable properties of unweighted networks are not easily generalized to weighted …

In social network analysis, brokerage refers to the processes through which individuals or
larger groups mediate interactions between actors that would otherwise not be directly …

Exotic species invasion is widely considered to affect ecosystem structure and function. Yet,
few contemporary approaches can assess the effects of exotic species invasion at such an …

We used stable isotope ratios of nitrogen (15 N/14 N) as a validation tool for determining the
accuracy of the effective trophic levels computed in network analysis models for Core …
