Abstract:

The development of an individual-based model computer code of sediments and organisms that utilizes biologically relevant parameters, such as animal sizes, population density, feeding and locomotion rates and probabilities for observed behavior, to drive the model and produce predictions about sediment composition and fabric. Biologically active sediment is represented on a computer as a regular lattice of quasi-particles with individually assigned chemical, biological or physical properties. Modal benthic organisms are introduced in the form of automatons, i.e., programmable entities, that are capable of moving through the particle lattice by displacing or ingesting-defecating particles. Each automaton obeys a set of rules, both deterministic and stochastic, designed to mimic real organism behavior, with different types of organisms having different sets of rules.
