Biological Production in Lakes. Physical Processes in Terrestrial and Aquatic Ecosystems, Ecological Processes.
Walters, R. A.; Carey, G. F.
These materials were designed to be used by life science students for instruction in the application of physical theory to ecosystem operation. Most modules contain computer programs which are built around a particular application of a physical process. Primary production in aquatic ecosystems is carried out by phytoplankton, microscopic plants which move with water currents. The yearly pattern of biological production is in large part controlled by a seasonal cycle of thermal stratification. This module presents a model of primary production in a lake ecosystem. The principal physical, chemical, and biological processes are introduced and the formulation of the model and the mathematical approach used to work with it are described. A final section discusses running the model and modifying its input or boundary conditions so it can be used to simulate a variety of situations. Exposure to numerical analysis and differential equations is a prerequisite to use of the module. (Author/CS)
