Titulo: Portuguese continental shelf ecosystem under the future climate - insights from the spatial-temporal food-web model.
Abstract: Climate change is affecting the spatial distributions of marine species globally. Consequently, marine ecosystems worldwide are expected to undergo significant reorganisations in dominant species, commercial fish resources and biodiversity. In this study, we used the mechanistic spatial-temporal food web model (Ecopath with Ecosim and Ecospace) of the Portuguese continental shelf ecosystem (PCSE) to demonstrate and assess the changes in this ecosystem under future climate scenarios. We run future climate projections (RCP45 and RCP85) combined with scenarios simulating alternative marine management measures (MPA and sustainable fishing) to demonstrate plausible future changes in the ecosystem and to assess if the management actions can counteract them. Results showed that the composition of marine fish communities is expected to shift under the future climate and replacement between species will occur. This will affect the
fisheries, ecosystem biodiversity and its stability. Management scenarios showed the potential to counteract some of the adverse effects expected to happen in future, while the others are inevitable regardless of the applied measures. This study highlights the need to
develop socio-economic adaptation strategies to climate change and emphasize the urgency to implement management actions that have the potential to counteract the adverse effects of climate change.
Biography: Dorota Szalaj is an ecosystem modeler, currently working as a post-doctoral researcher at the Marine Science Institute in Barcelona (ICM-CSIC). Her main research interests include the ecosystem approach to fisheries management, spatial-temporal ecosystem modeling and climate change impact on marine ecosystems and fisheries. Since 2016 she has been a member of the ICES working group on Ecosystem Assessment of Western European Shelf Seas (WGEAWESS). This group provides the ecosystem advice product for ICES and EU. Moreover, she is a member of the Joint Research Centre (JRC) network of Experts for ReDeveloping Models for the European Marine Environment (MEME) and Integrated Marine Ecosystem Assessments (iMARES) research group coordinated by Dr Marta Coll Monton.
