Food webs-networks of predators and prey-have long been known to exhibit "intervality": species can generally be ordered along a single axis in such a way that the prey of any given predator tend to lie on unbroken compact intervals. Although the meaning of this axis-usually identified with a "niche" dimension-has remained a mystery, it is assumed to lie at the basis of the highly non-trivial structure of food webs. With this in mind, most trophic network modelling has for decades been based on…

The origin of motif families in food webs
TLDR
It is found that most food webs fall into one of two distinct motif families, and trophic coherence is also a good predictor for the extent of omnivory, defined as the tendency of species to feed on multipleTrophic levels.
Looplessness in networks is linked to trophic coherence
TLDR
It is shown that trophic coherence, a structural property of ecosystems, is key to the extent of feedback in these as well as in many other systems, including networks related to genes, neurons, metabolites, words, computers, and trading nations.
From neurons to epidemics: How trophic coherence affects spreading processes.
TLDR
It is found that trophic coherence can exert a qualitative change in spreading behaviour, determining whether a pulse of activity will percolate through the entire network or remain confined to a subset of nodes, and whether such activity will quickly die out or endure indefinitely.
How directed is a directed network?
TLDR
This work proposes simple improved definitions of trophic levels and coherence that can be computed on any directed network and demonstrates how the method can identify node function in examples including ecosystems, supply chain networks, gene expression and global language networks.
Digraphs are different: why directionality matters in complex systems
TLDR
It is shown here that these topological properties have a common origin, in that the edges of directed networks can be aligned - or not - with a global direction, and how this can lead to rich and unexpected dynamical behaviour even in the simplest of models.
Social Stratification from Networks of Leveling Ties
TLDR
Ties that are neither positive nor negative to have, but an indication of commonality are highlighted, exemplified by the derivation of socio-economic status from networks that indicate common class membership.
ResNetX: a more disordered and deeper network architecture
TLDR
The architecture is a natural extension to ResNet, and can be integrated with existing state-of-the-art methods with little effort, and exposes a new dimension, namely "fold depth", in addition to existing dimensions of depth, width, and cardinality.

Trophic coherence determines food-web stability
TLDR
It is shown that trophic coherence—a hitherto ignored feature of food webs that current structural models fail to reproduce—is a better statistical predictor of linear stability than size or complexity, and it is proved that a maximally coherent network with constant interaction strengths will always be linearly stable.
The phylogenetic component of food web structure and intervality
TLDR
It is found that the phylogenetic relationships provide a significant background from which to estimate food web intervality and thereby structure, but there is an important, non-negligible part of some traits, e.g., body size, in food webs that is not accounted for by the phylogenetics relationships.
Emergence of complexity in evolving niche-model food webs.
QUANTITATIVE PATTERNS IN THE STRUCTURE OF MODEL AND EMPIRICAL FOOD WEBS
TLDR
It is demonstrated that the quantitative unifying patterns that describe the properties of the food-web models considered earlier also describe the majority of the empirical webs considered, and that the empirical distributions of number of prey and number of predators follow universal functional forms that match the analytical predictions.
Phylogenetic constraints and adaptation explain food-web structure
TLDR
A new model built on the hypothesis that any species' diet is the consequence of phylogenetic constraints and adaptation is proposed, which better reflects the complexity and multidimensionality of most natural systems.
From neurons to epidemics: How trophic coherence affects spreading processes.
TLDR
It is found that trophic coherence can exert a qualitative change in spreading behaviour, determining whether a pulse of activity will percolate through the entire network or remain confined to a subset of nodes, and whether such activity will quickly die out or endure indefinitely.
Food-web structure in low- and high-dimensional trophic niche spaces
TLDR
It is shown that the degrees of intervality observed in nature can be reproduced in arbitrary-dimensional trophic niche spaces, provided that the processes of evolutionary diversification and adaptation are taken into account.

TLDR
It is shown that within habitats of a certain limited physical and temporal heterogeneity, the overlaps among niches, along their trophic dimensions, can be represented in a one-dimensional niche space far more often than would be expected by chance alone and perhaps always.
