A central problem in ecology is determining the processes that shape the complex networks known as food webs formed by species and their feeding relationships. The topology of these networks is a major determinant of ecosystems' dynamics and is ultimately responsible for their responses to human impacts. Several simple models have been proposed for the intricate food webs observed in nature. We show that the three main models proposed so far fail to fully replicate the empirical data, and we… 

Architecture of marine food webs: To be or not be a ‘small-world’

The first rigorous analysis of the small-world topology and its associated features in high-quality marine networks concludes that such topology is a structural pattern that is not maximized in marine food webs; thus it is probably not an effective model to study robustness, stability and feasibility of marine ecosystems.

The Role of Stochastic Simulations to Extend Food Web Analyses

The dominator tree is presented, a topological structure reducing food web complexity into linear pathways that are essential for energy delivery and stochastic simulations are introduced to suggest an alternative approach to static analyses based on food web topology.

Relevance of evolutionary history for food web structure

It is shown that food webs are best explained by the coarser taxonomic ranks (kingdom to class) and the methods provide a way to explicitly include evolutionary history in models for food web structure.

Individual-Based Food Webs

Constraints and variation in food web link-species space

This study provides new insights into the long-standing question of which factors determine the relationship between the number of links and species, and shows that accounting for these 'forbidden interactions' constrains the feasible link-species space.

A simple model of bipartite cooperation for ecological and organizational networks

This work proposes a highly parsimonious model that can reproduce the overall bipartite structure of cooperative partner–partner interactions, as exemplified by plant–animal mutualistic networks, and tests it on ten large pollination data sets.

Dynamical stability and complex topologies : patterns and mechanisms in food webs LAVRAS – MG 2018

Food-web theory evaluates feeding relations between species, and has been recognized as one of the fundamental principals in ecology. However, in order to account for the complexity in which these



Phylogenetic constraints and adaptation explain food-web structure

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.

Simple rules yield complex food webs

This model extends the existing ‘cascade model’ and improves its fit ten-fold by constraining species to consume a contiguous sequence of prey in a one-dimensional trophic niche.

Modelling Coevolution in Multispecies Communities.

The Webworld model is introduced, which links together the ecological modelling of food web structure with the evolutionary modelling of speciation and extinction events, and the theory of self-organized criticality is discussed.

It is shown that complex, realistic food webs may emerge by evolution from a single ancestor based on very simple ecological and evolutionary rules.

A robust measure of food web intervality

It is concluded that empirical food webs actually do exhibit a strong bias toward contiguity of prey, that is, toward intervality, which validates a critical assumption in the recently proposed static niche model and provides guidance for ongoing efforts to develop dynamic models of ecosystems.

Food webs: experts consuming families of experts.

Food web patterns and their consequences

Although webs were often initially reported in despair at ever understanding ecological complexity, recently discovered widespread patterns in the shapes of webs, and theoretical explanations for these patterns, indicate that webs are orderly and intelligible, and have some foreseeable consequences for the dynamics of communities.
