Microbial food chains and food webs
Journal of Theoretical Biology, 1973Abstract 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.

Stoichiometry and food-chain dynamics
Theoretical Population Biology, 2004Traditional 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.

An explanation of soil amendments to reduce cadmium phytoavailability and transfer to food chain.
Science of the Total Environment, 2019Cadmium contamination in soil, water and food has become a global problem since last century's industrial and agricultural revolution. It is a highly toxic metal with serious consequences on human and animal health.

Contextual Integrity Up and Down the Data Food Chain
Theoretical Inquiries in Law, 2019According to the theory of contextual integrity (CI), privacy norms prescribe information flows with reference to five parameters — sender, recipient, subject, information type, and transmission principle.

Trophic Transfer of Antibiotic Resistance Genes in a Soil Detritus Food Chain.
Environmental Science and Technology, 2019The presence and spread of antibiotic resistance genes (ARGs) are causing substantial global public concern; however, the dispersal of ARGs in the food chain is poorly understood.
