| Key qualifications | ||
 | Experience in understanding and modelling ecosystem interactions. I use my own simulation model named FieldEco, which is a physiologically driven, temperature dependent population dynamic model. It has been developed to simulate food web interactions and competition, e.g. plants competition, animal competition, plant - herbivore interactions and predator - prey interactions. Furthermore, the models are used to simulate the impact of abiotic factors such as temperature, nitrogen availability, xenobiotics and soil cultivation on the population dynamics and ecosystem interactions. | |
