The geometry of evolved community matrix spectra
Scientific Reports, 2022 Random matrix theory has been applied to food web stability for decades, implying elliptical eigenvalue spectra and that large food webs should be unstable.

No complexity–stability relationship in empirical ecosystems
Nature Communications, 2016 A long-standing ecological hypothesis is that complexity should decrease stability in food webs. Here, Jacquet and colleagues analyse over 100 real-world food webs and show that complexity does not decrease stability, but that a high frequency of weak ...

IsoWeb: a bayesian isotope mixing model for diet analysis of the whole food web. [PDF]
PLoS ONE, 2012 Quantitative description of food webs provides fundamental information for the understanding of population, community, and ecosystem dynamics. Recently, stable isotope mixing models have been widely used to quantify dietary proportions of different food ...

Plant communities and food webs
Frontiers in Ecology and Evolution, 2023 Recent theoretical work has provided major new insights into the ways that species interactions in food webs are organized in ways that permit the coexistence of significant numbers of species. But, we seem to have forgotten about trees!

Generalized models reveal stabilizing factors in food webs [PDF]
, 2009 Insights into what stabilizes natural food webs have always been limited by a fundamental dilemma: Studies either need to make unwarranted simplifying assumptions, which undermines their relevance, or only examine few replicates of small food webs ...

Hierarchicalization of chaotic food webs using Interpretive Structural Modeling [PDF]
Network Biology, 2013 Ecologists always meet complex food webs without clear hierarchical structure. At certain degree it will retard further analysis of food webs. In present study we transferred chaotic food webs into hierarchicalized food webs using Interpretive Structural

Population Dynamics on Complex Food Webs [PDF]
, 2011 In this work we analyse the topological and dynamical properties of a simple model of complex food webs, namely the niche model. In order to underline competition among species, we introduce "prey" and "predators" weighted overlap graphs derived from the

Neonicotinoids disrupt aquatic food webs and decrease fishery yields
Science, 2019 Cascading effects of pesticide use It is now well known that neonicotinoids negatively affect pollinators. As research has expanded, it has become clear that these globally used insecticides directly affect other ecosystem components, including ...

Disentangling higher trophic level interactions in the cabbage aphid food web using high-throughput DNA sequencing [PDF]
Metabarcoding and Metagenomics, 2017 The lack of understanding of complex food-web interactions has been a major gap in the history of biological control. In particular, a better understanding of the functioning of pest food-webs and how they vary between native and invaded geographical ...

The origin of motif families in food webs [PDF]
, 2017 Food webs have been found to exhibit remarkable “motif profiles”, patterns in the relative prevalences of all possible three-species subgraphs, and this has been related to ecosystem properties such as stability and robustness.
