Workvisit to Dina Lika, Iraklion 2010/05/12 S.A.L.M. Kooijman Dept Theoretical Biology, Vrije Universiteit, Amsterdam bas@bio.vu.nl; http://www.bio.vu.nl/thb/ Applications of Dynamic Energy Budget (DEB) theory DEB theory is about the uptake and use of substrates by all organisms (micro-organiosms, animals, plants), based on first principles in chemistry, physics & biology. I will illustrate the following applications of the standard DEB model: - reconstruction of food-density and temperature trajectories in the environment from data on = growth (using birds) = reproduction (using daphnia) = otoliths (of fish) - identification of mode of action of toxicants and quantification of effects - prediction of tumour growth as affected by caloric restriction - optimisation of bio-production = yield in micro-organisms = prediction of spawing in pacific oysters
