Descripción del proyecto
"In all pelagic marine food-webs, zooplankton are the critical link between the phytoplankton primary producers and higher trophic levels, including fish. On-going changes observed for zooplankton communities in the Mediterranean and other oceans around the world therefore have serious implications for food-web productivity, and their continued provision of ecosystem services (e.g., food security). Current gaps in our knowledge of how the zooplankton component of the food-web functions, limit our ability to sustainably manage our marine resources.
The ISOZOO program is designed to make a significant contribution to our understanding of zooplankton food-web processes, and how climate change and anthropogenic impacts affect these. Facilitated by IIF mobility, this overarching goal will be achieved by a multi and interdisciplinary approach, combining stable isotope ecology, ocean biochemistry, physical and biological oceanography, and ecosystem modelling. Working with a set of collaborators at the LOPB in Marseille, we will define Phyto-Zooplankton relationships across a range of nutrient conditions, and estimate the impact of these relationships on zooplankton food-chain length and transfer efficiencies. Established relationships between zooplankton and phytoplankton-nutrients will be used to: 1. develop an Index of zooplankton food-web status that can be applied to monitor food-web response to changing ocean conditions (physics & nutrients) and, 2. parameterise the Eco3M bio-physical model for the Gulf of Lion, to simulate/predict the impacts of climate change and anthropogenic forcing on ecosystem function. Together objectives 1 and 2 should allow for better informed management of marine resources given future variability. Through collaboration beyond the time frame of this project we aim to develop world-wide application of the Food-Web Index (1) and model parameters (2) through networks of international collaborators for climate change monitoring and research."
