Modern models of trophic meta-communities [PDF]
Philosophical Transactions of the Royal Society B: Biological Sciences, 2020 Dispersal and foodweb dynamics have long been studied in separate models. However, over the past decades, it has become abundantly clear that there are intricate interactions between local dynamics and spatial patterns. Trophic meta-communities, i.e. meta-foodwebs, are very complex systems that exhibit complex and often counterintuitive dynamics.

Trophic dynamics of a simple model ecosystem [PDF]
Proceedings of the Royal Society B: Biological Sciences, 2017 We have constructed a model of community dynamics that is simple enough to enumerate all possible food webs, yet complex enough to represent a wide range of ecological processes. We use the transition matrix to predict the outcome of succession and then investigate how the transition probabilities are governed by resource supply and immigration.

Modelling lake trophic state: A random forest approach [PDF]
Ecosphere, 2015 Productivity of lentic ecosystems is well studied and it is widely accepted that as nutrient inputs increase, productivity increases and lakes transition from lower trophic state (e.g. oligotrophic) to higher trophic states (e.g. eutrophic).

Mathematical Models of Retinitis Pigmentosa: The Trophic Factor Hypothesis [PDF]
Journal of Theoretical Biology, 2021 AbstractRetinitis pigmentosa (RP) is the term used to denote a group of inherited retinal-degenerative conditions that cause progressive sight loss. Individuals with this condition lose their light-sensitive photoreceptor cells, known as rods and cones, over a period of years to decades; degeneration starting in the retinal periphery, and spreading ...

Trophic structure of litter mesofauna: biomass differentiation between trophic levels
Vìsnik Dnìpropetrovsʹkogo Unìversitetu: Serìâ Bìologìâ, Ekologìâ, 2008 On the basis of research of litter mesofauna in four forest biogeocenoses of the Poltava region the trophic-weight models of invertebrate communities are creating.

Plankton food-webs: to what extent can they be simplified?
Advances in Oceanography and Limnology, 2016 Plankton is a hugely diverse community including both unicellular and multicellular organisms, whose individual dimensions span over seven orders of magnitude.

Ecological Indicators, 2022 Habitat models have gradually become important tools for assessing and predicting the spatio-temporal distribution of marine organisms. Species are closely associated with each other through biological processes such as predation, competition and ...

Rheagogies: Modelling non-trophic effects in food webs [PDF]
Ecological Complexity, 2005 Abstract In a food web, nutrients flow via trophic links. For this reason, trophic interactions have a fundamental character due to the principle of mass conservation. To further comply with this principle, we consider a food web model that includes nutrient cycling.

Petri Nets for Modelling and Analysing Trophic Networks [PDF]
Fundamenta Informaticae, 2018 We consider trophic networks, a kind of networks used in ecology to represent feeding interactions (what-eats-what) in an ecosystem. Starting from the observation that trophic networks can be naturally modelled as Petri nets, we explore the possibility of using Petri nets for the analysis and simulation of trophic networks.

Uncertainty Management in Coupled Physical-Biological Lower Trophic Level Ocean Ecosystem Models [PDF]
Oceanography, 2013 Lower trophic level (LTL) ocean ecosystem models are important tools for understanding ocean biogeochemical variability and its role in Earth's climate system.
