Primary production Modelling

Lake ecology is characterized by complex interactions between physical, chemical and biological processes. Our goal is to apply coupled physical-biogeochemical model systems to understand food web dynamics in lake ecosystems, with particular focus on long-term changes in primary production patterns in oligotrophic lakes. We also study how climate change and variations in internal nutrient loadings affects carbon fixation rates of phytoplankton and their community composition, and consequent bottom-up effects on higher trophic levels. Another aspect of our research is skills evaluation of models based on model-data misfits, parameter uncertainties and robustness of solutions. (Shubham Krishna, Fabio Lepori and others)
