From neurons to epidemics: How trophic coherence affects spreading processes [PDF]

, 2016
Trophic coherence, a measure of the extent to which the nodes of a directed network are organised in levels, has recently been shown to be closely related to many structural and dynamical aspects of complex systems, including graph eigenspectra, the ...

Differences in trophic structure and trophic pathways between artificial reef and natural reef ecosystems along the coast of the North yellow Sea, China, based on stable isotope analyses

Ecological Indicators, 2021
Artificial reefs have been employed to promote enrichment of degraded habitats communities and support local fisheries. To better evaluate the performance of artificial reefs, simultaneous comparisons with relatively undisturbed natural reefs nearby are ...

A Statistical Social Network Model for Consumption Data in Food Webs

, 2013
We adapt existing statistical modeling techniques for social networks to study consumption data observed in trophic food webs. These data describe the feeding volume (non-negative) among organisms grouped into nodes, called trophic species, that form the

Trophic cascade modelling in bathyal ecosystems

, 2023
Different aspects of the bathyal ecosystem have been treated with the final aim to investigate trophic cascades driven by fishery (top-down control), a phenomenon that in bathyal systems has never been studied. This was exemplified by the in-depth study of the exploited soft-bottom continental slope off Catalonia (NW Mediterranean), where the fishery ...

Evidence for a multi-level trophic organization of the human gut microbiome.

PLoS Computational Biology, 2019
The human gut microbiome is a complex ecosystem, in which hundreds of microbial species and metabolites coexist, in part due to an extensive network of cross-feeding interactions.

Emergent global patterns of ecosystem structure and function from a mechanistic general ecosystem model [PDF]

, 2014
Anthropogenic activities are causing widespread degradation of ecosystems worldwide, threatening the ecosystem services upon which all human life depends.

Predicting plankton net community production in the Atlantic Ocean [PDF]

, 2009
We present, test and implement two contrasting models to predict euphotic zone net community production (NCP), which are based on 14C primary production (PO14CP) to NCP relationships over two latitudinal (ca.

A general approach to the modelling of trophic chains [PDF]

Ecological Modelling, 2000
Based on the law of mass action (and its microscopic foundation) and mass conservation, we present here a method to derive consistent dynamic models for the time evolution of systems with an arbitrary number of species. Equations are derived through a mechanistic description, ensuring that all parameters have ecological meaning.
