Models relating to terrestrial mineral cycling : progress report

Creator:

Strand, Mary Ann Sall, U.S. International Biological Program. Coniferous Forest Biome, and University of Washington

Abstract:

Although no formal project in mineral cycling was defined for 1972, three modeling efforts were begun: calcium cycling at Cedar River, litter decomposition, and miombo ecosystem. The calcium cycling model is a simple compartment model and was developed as a practice exercise. It demonstrates the inadequacy of linear-donor control formulation...

A conceptual model of soil mass movement, surface soil erosion, and stream channel erosion processes

Swanson, Frederick J. (Frederick John), 1943-, Swanston, Douglas N., Dyrness, C. T., Cromack, Kermit, Fredriksen, R. L., Moore, Duane G., Glenn, Leslie Fred, 1944-, U.S. International Biological Program. Coniferous Forest Biome, and University of Washington

Abstract:

The conceptual framework of an erosion model has been designed to link processes of mass wasting, surface erosion, and channel storage and transport. A program to stimulate mass wasting will be based on a variation of the factor of safety approach which balances forces tending to drive mass movement against...

Trophic relation model based on density dependent processes

Creator:

Warren, Charles E., 1926-, U.S. International Biological Program. Coniferous Forest Biome, and University of Washington

Abstract:

"We have developed graphical and logical models for explaining the production of a consumer on the basis of the capacity of an ecosystem to produce that consumer (the productivity of the system for that consumer), on the basis of the biomass of the consumer, and on the basis of the...

Report of the aquatic modeling group : round one

Creator:

McIntire, C. David, Hall, James D., Higley, Duane Lee, U.S. International Biological Program. Coniferous Forest Biome, and University of Washington

Abstract:

The aquatic modeling group, consisting of Davis, Donaldson, Hall, Higley, Lyford, McIntire, Mullooly, Overton, Strand, Waring, and Warren, met in four 2-hour sessions from July 7 to July 26. The charge to the group was: 1. Define an appropriate internal structure for the aquatic subsystem; 2. Define significant couplings between...

Periphyton dynamics in lotic environments : a simulation model

Creator:

McIntire, C. David, U.S. International Biological Program. Coniferous Forest Biome, and University of Washington

Abstract:

The simulation model described below is based on the assumption that the periphyton community can be treated as a unit, without a quantitative concern for the dynamics of its many constituent populations. The function statements and parameter estimates incorporated into the model are based on experimental work with laboratory streams...

An analytical model for gas exchange studies of photosynthesis

Creator:

Reed, Kenneth Lee, 1942-, Hamerly, Eddie R., Dinger, Blaine E. (Blaine Elroy), 1941-, U.S. International Biological Program. Coniferous Forest Biome, and University of Washington

Abstract:

A steady-state model designed especially for analysis of gas exchange studies of terrestrial net photosynthesis is discussed. The model expresses net photosynthesis as a function of light, temperature, CO₂ concentration, stomatal resistance, and other factors. The parameters of the model are estimated from data by nonlinear least-squares. The data set...

Stand structure simulation based on individual tree units

Creator:

Farnum, Peter, U.S. International Biological Program. Coniferous Forest Biome, and University of Washington

Abstract:

A model is developed to simulate basal area growth and mortality for forest stands using individual trees as the basic units. Yearly diameter increment, probability of death, and height-diameter relationship are computed from a competition measure which is based on crown overlap. This model is used to simulate the growth...

Documentation for a combined carbon-water flow stand level coniferous forest model

Creator:

Swartzman, G. L. (Gordon L.), Sollins, P., U.S. International Biological Program. Coniferous Forest Biome, and University of Washington

Abstract:

The following report Introduces a documentation scheme for flow oriented ecosystem models and shows its application to a carbon-water model developed within the coniferous biome. This documentation scheme has remained operative through revision of this model and expansion of It to include nutrient flows. This model and subsequent versions are...
