CONIFER simulates water, carbon, and energy dynamics of a coniferous forest. The model consists of 29 nonlinear difference equations. Driving variables include air temperature, dew point temperature, precipitation, solar radiation, and wind speed. Water and energy variables are updated daily; carbon variables are updated weekly. This report contains a detailed...
This proposal requests support for a highly integrated series of investigations within the Analysis of Ecosystem Program of the United States effort under the international Biological Program. The program for the Coniferous Forest Biome has been approved by the U. S. Executive Committee for the IBP as an integrated research...
This volume results from an experiment in data retrieval. During the initial stage of the Coniferous Forest Biome the authors were asked to provide access to the literature on mammals as it pertained to the interests of the Biome investigation. One constraint was that the total number of entries should...
Three aspects of lotic ecology have been analyzed utilizing data collected from totally autotrophic-based streams maintained by the Weyerhaeuser Company: energy transfer, effects of nitrogen addition, and simulation
modeling. All three streams had very similar periphyton, grazer, collector,
invertebrate predator, and vertebrate predator (fish) communities during
the study period (1972-1974)....

This proposal by the Coniferous Biome investigators requests support for the second year of a highly integrated series of investigations within the Analysis of Ecosystem program of the United States effort under the International Biological Program. The program for the Coniferous Forest Biome has been approved by the U.S. Executive...
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...
The Coniferous Forest Biome was initially funded in 1970 by the National
Science Foundation as a large-scale, interdisciplinary, interinstitutional
research program to study coniferous forest and associated aquatic ecosystems.
It was initiated as one of the Integrated Research Programs in
the Ecosystem Analysis Section of the U.S./International Biological
Program (US/IBP)....
The specific objectives of the program are: (1) To understand the relative behavior of terrestrial and aquatic ecosystems in various environments in the biome. (2) To develop conceptual and computer simulation models that describe nutrient, carbon, and waterflows on a short-term basis (fewer than ten years) and which integrate research...
The insects that invade a dying or dead tree are the immediate cause of death and the principle mediators of early stages of decomposition of the tree. These insects form a large and complex community, the species
components of which are restricted to particular habitats. A study of
the insect...
SIMCOMP is a computer programming system which is designed to aid biologists with a limited knowledge of FORTRAN programming to design and execute compartment-flow simulations. The system is designed to minimize the programming overhead required by any computer language while maintaining
sufficient flexibility of FORTRAN. This flexibility does allow interfacing...
"During the four meetings of the consumer modeling committee, discussion centered on the formation of systems models and the
problems they will pose for researchers concerned with consumer populations. Two coarse models were developed from these discussions, a compartment model (Figure 1) and a process model (Figure 2). The
compartments...
