Mathematical models for biological processes
ECOSTAT develops, tests and evaluate mathematical and computer simulation models for biological processes.
ECOSTAT offers to develop models for the biological processes you are investigating. These
models will, of course, always be developed in close co-operation.
ECOSTAT can also estimate the parameters of these models.
For complex models, ECOSTAT recommends to perform a sensitivity analysis of the model results. ECOSTAT can assist you with such an analysis.
If you have a model and wish for a general critical evaluation ("second opinion"), ECOSTAT can offer it.
Some examples of ECOSTAT's experience
- A method to estimate the effect of a sediment on bioluminescence in MSP tests with marine sediments. The effect was classified in two types, binding to the sediment and the effect of chemicals in the sediment on the bioluminescence. A method was developed to estimate the second effect.
- A critical evaluation of a probabilistic model to translate laboratory data on toxic chemicals to environmental standards for soils and sediments.
- Four models were developed to describe the effect of seed weight on the probability that a seed of the Carapa tree was taken away and concealed by agouties. It was investigated which relationship between seed weight and that probability best described the observed distribution of seeds taken and concealed. It was also investigated whether the decision scheme of the agouties depended on the total harvest of seeds. This research is described in van der Hoeven et al., 2004.
