Optimal ecosystem management using network theory

This project aims to develop novel approaches combining network theory, optimisation, and decision science to model complex ecosystem dynamics for optimal ecosystem management. We take into account species-ecosystem function-ecosystem services relationships to address the long lasting debate between conservation for biodiversity vs conservation for ecosystem services. We use both simulations and empirical case studies to show that biodiversity-ecosystem services trade-offs depends on the ecosystem network structure and specific ecological features (i.e., trophic levels of the species providing the ecosystem services/functions). Uncertainty, the value of information, and the risk preference of the managers are also considered in this project to improve the optimal conservation decision making.
