MODEL METHODS FOR THE ANALYSIS OF MESOCOSM EXPERIMENTAL STUDIES

The response of experimental ecosystem dynamics to varying nutrient lo ads was studied by analysing oxygen time-series. Time-series had been continuously recorded, and the data were analysed on a daily basis usi ng a computer model which describes basic oxygen processes. The result ing sets of production and consumption parameters described the dynami c characteristics of each basin during the experimental period of 180 days. Dynamical analysis appeared to be possible; although the results did not indicate a clear relationship between oxygen dynamics and nut rient supply in these systems.
