Observability and observers in a food web
Applied Mathematics Letters, 2007 The problem of the possibility to recover the time-dependent state of a whole population system out of the observation of certain components has been studied in earlier publications, in terms of the observability concept of mathematical systems theory. In the present note a method is proposed to effectively calculate the state process.

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!

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

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 ...

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.

, 2022 Ciliates are important elements of the trophic networks of aquatic and terrestrial environments, they can be primary producers (myxotrophs), consumers of bacteria, algae, flagellates, even other ciliates and can serve as food for metazoans, for all the above they are the link between different levels of food webs.

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 ...

Food Chains and Food Webs in Aquatic Ecosystems
Applied Sciences, 2020 Food chains and food webs describe the structure of communities and their energy flows, and they present interactions between species. Recently, diverse methods have been developed for both experimental studies and theoretical/computational studies on ...

Compilation and network analyses of cambrian food webs. [PDF]
PLoS Biology, 2008 A rich body of empirically grounded theory has developed about food webs--the networks of feeding relationships among species within habitats. However, detailed food-web data and analyses are lacking for ancient ecosystems, largely because of the low ...
