Three modeling approaches were taken in 1972. These were: compartmentmodeling, fine level process modeling, and coarse level process modeling.The compartment model is of a litter layer arthropod community. It has beenformulated and parameterized, but a computer program for simulation has notbeen written. The fine level process model is a generalized model of aconsumer population. This model couples population dynamics and energeticsin its representation of eight basic consumer processes. Submodels ofseveral processes have been tested for different consumer types, but twoprocesses have not been adequately formulated yet. The total model has notbeen tested. The coarse level process model investigates the influence ofthe structure of food chains on the rate of secondary production and ofpassage of materials through the food chain. Two food chains have beenexamined and several more will be simulated prior to production of a foLualreport.
