Microbial food chains and food webs

Journal of Theoretical Biology, 1973
Abstract Mathematical models for simple microbial food chains and food webs in continuous culture are developed and analyzed. A model for competition of two microbial species for a single scarce resource is also presented as a degenerate case of the food web model. Two models for food chains are developed.

Food Chains in Freshwaters

Annals of the New York Academy of Sciences, 2009
There are three hypothesized controls on food‐chain length (FCL): energy supply (or “resource availability”), ecosystem size and disturbance (or “environmental variation”). In this article, the evidence for controls on FCL in freshwater ecosystems is evaluated. First, the various ways FCL can be measured are defined.

Stoichiometry and food-chain dynamics

Theoretical Population Biology, 2004
Traditional models of chemostat systems looking at interactions between predator, prey and nutrients have used only a single currency, such as energy or nitrogen. In reality, growth of autotrophs and heterotrophs may be limited by various elements, e.g. carbon, nitrogen, phosphorous or iron.
