Description

This project will investigate how holometabolous insects can be included in the Dynamic Energy Budget (DEB) theory by (1) studying the responses of the flour beetle Tribolium castaneum (Coleoptera: Tenebrionidae) to different stressors, (2) deriving a DEB-based bioenergetics model(s) explaining the holometabolic life cycle, and (3) applying the derived model(s) to explore metabolic costs of tolerance to copper exposure. These tasks are essential parts of the project to be achieved through an iterative feedback mechanism between experimental and modelling parts of the project activities. The Institute of Environmental Sciences is in possession of several unique T. castaneum cultures, maintained at different conditions for more than 20 generations, providing an unparalleled animal model to address the abovementioned research objectives.
