Increase in temperature, changing patterns in ocean currents, and productivity, are affecting the distributions of marine species globally. Due to increasing temperature northward expansion of marine species has been documented and an increasing number of studies confirmed an intensification of this trend in the next decades. In this study, we used the ecosystem food web model, Ecopath with Ecosim, to demonstrate how the Portuguese continental shelf ecosystem has changed over the last three decades, and how this ecosystem is expected to change under future climate predictions. The ecosystem indicators, that describe the ecosystem state, indicate that over the last three decades, the stability, resilience and biodiversity of this ecosystem have decreased, and future predictions show a continuation of this tendency. The main changes observed in this ecosystem were related to changes in the pelagic community that shifted from sardine, the main fishing resource, to other less valuable pelagic fishes such as chub mackerel. In this study, we also explore if, and to what extent, management strategies such as marine protected areas, essential habitat restoration and sustainable fisheries practices, can diminish or counteract expected changes. Ecosystem food web models such as Ecopath with Ecosim describe trophic flows between organisms within an ecosystem, therefore they can be useful to inform about marine functional connectivity, ecosystem functions and their services. As demonstrated in this study, these types of models can provide information about the future fate of ecosystems and marine species under future climate scenarios. Moreover, this information can support the strategic management of marine resources and marine ecosystems Peer reviewed 2024-07-11T10:59:15Z 2024-07-11T10:59:15Z 2023-05-22 comunicación de congreso Symposium on Human Impacts on Marine Functional Connectivity (2023) http://hdl.handle.net/10261/363424 en Sí none |
