Simulation in the service of environmental research: experience with a stream ecosystem project

PDF Version Also Available for Download.

Description

A perspective on the use of simulation modeling as one working component of a complex ecosystem research project is presented. Experiences with modeling in the context of a research program dealing with nutrient dynamics in stream ecosystems are documented. As the project progressed, the role of modeling changed, resulting in four distinct models, each developed for a specific purpose. The models have been used to screen initial hypotheses, set up details of the experimental design, analyze results, and serve as a logical framework for investigating mechanistic details of the ecosystem. Through time, individual models were discarded, not because they were ... continued below

Description

A perspective on the use of simulation modeling as one working component of a complex ecosystem research project is presented. Experiences with modeling in the context of a research program dealing with nutrient dynamics in stream ecosystems are documented. As the project progressed, the role of modeling changed, resulting in four distinct models, each developed for a specific purpose. The models have been used to screen initial hypotheses, set up details of the experimental design, analyze results, and serve as a logical framework for investigating mechanistic details of the ecosystem. Through time, individual models were discarded, not because they were inadequate, but because they were irrelevant to the next stage of the project. It was particularly interesting to note how the importance of validation, as well as its characteristics, have changed during this process.
