We discuss some of the problems of effect models in ecotoxicology. We focus on Monte Carlo simulation studies and demonstrate the effect of parameter variance, time horizon of predictions and alternative model algorithms on model predictions. Our res

Using SIM-PEL, a comprehensive model for the pelagic compartment of lake ecosystems, we analyse synergistic toxicant effects in lake ecosystems. We show, that — even for a rather simple model — model predictions may be strongly dependent on the t

Bei der Simulation okologischer Systeme besteht grose Unsicherheit bezuglich der zu verwendenden Modellparameter und Modellgleichungen. Diese Unsicherheit kann mit den prohabilistischen Methoden der Risikoanalyse in die Modellaussage integriert werde

For a generalized mathematical model of the pelagic compartment of a lake ecosystem we show that a small variance in input parameters may result in a large variance in predicted biomasses. Since input parameters for this kind of models always show a

Results of excitation density and temperature dependent photoluminescence experiments on In 0.53 Ga 0.47 As/InP and In 0.75 Ga 0.25 As 0.5 P 0.5 /InP heterostructures grown by LP-MOCVD are reported. The samples show a two dimensional electron gas at
