C-GRASS – Seagrass meadows: Blue carbon spatio-temporal changes at Murtosa region (Ria de Aveiro)
Résumé
Seagrass meadows are globally significant blue carbon (C) sinks contributing to climate regulation, reduce sediment erosion and increase the sediment stability; thus, playing a key role in many ecosystem functions and ecological processes. Nevertheless, seagrass loss and degradation is occurring worldwide, leading to the release of C stored over millennia at these ecosystems. In Ria de Aveiro, seagrass meadows followed the global trend, and there was a great loss along the last decades of 20th century, mainly due to hydrological changes and dredging activities in the lagoon. Subtidal seagrass meadows disappeared and there was a great reduction of intertidal meadows extension and biodiversity. The harvesting of “moliço” (a mixture of seagrasses and macroalgae) and its use as fertilizer in agriculture was a traditional activity at Ria de Aveiro until the 1960’s. “Moliço” was collected and transported using traditional boats (“moliceiro”) and was frequently unloaded and commercialized at Murtosa wharfs. However, the economic value of this activity decreased over the 20th century and is currently lost. In the context of the OHM-Estarreja research topics “Biodiversity Evolution – ‘Evaluation of changes at Ria de Aveiro ecosystems’ and ‘Interaction among species, communities, population and ecosystems’”, this proposal intends to evaluate the spatio-temporal changes in Zostera noltei meadows at Murtosa region and the impacts of its vulnerability on the blue C stock. Potential drivers of change in these meadows will also be addressed.

Ana
Sousa
Ana I. Sousa is a post-doctoral researcher at Biology Department and CESAM, University of Aveiro. She holds a PhD in Biology (University of Lisbon, 2010) and has authored/co-authored 12 ISI-indexed papers, 5 book-chapters and 30 communications. A.I. Sousa has a research background in estuarine ecology and ecosystems functioning and dynamics. Her main research area/interests include ecosystem services provided by wetlands; blue carbon and nutrient dynamics in seagrass meadows and salt marshes; climate change impacts on coastal wetlands and its resilience to climate and other human-induced changes. A.I.Sousa coordinated the project MARSH-C-LEVEL(CNRS/OHMI-2015), focused on the role of Baixo-Vouga-Lagunar saltmarshes on carbon storage and assessment of sea-level-rise effects on their carbon storage capacity. She has been working on the Ria de Aveiro seagrass meadows mapping and vulnerability assessment. A.I.Sousa is involved in Ria Aveiro participation in LTER-Europe Marine-and-Transitional-Waters Task Force, whose main goal is to foster interactions among the LTER-Europe Marine-and-Transitional-Waters sites.

She holds a PhD in Biology (University of Lisbon, 2010) and has authored/co-authored 12 ISI-indexed papers, 5 book-chapters and 30 communications (h index=7). A.I.Sousa has a research background in estuarine ecology and ecosystems functioning and dynamics. Her main research area/interests include ecosystem services (ES) and Human benefits provided by wetlands; anthropogenic impacts on wetlands; blue carbon and nutrient dynamics in wetlands (salt marshes and seagrass meadows); climate change impacts on coastal wetlands and its resilience to climate and other human-induced changes; wetlands restoration. A.I.Sousa has participated in the LAGOONS project (Integrated water resources and coastal zone management in European lagoons in the context of climate change;EU-FP7) and LTER–RAVE project (Long-term monitoring in Ria Aveiro: towards a deeper understanding of ecological, environmental and economic processes;FCT-PT); developing research at Ria Aveiro coastal lagoon, mainly focused on wetlands’ functioning, remediation and storage capacity. She is involved in Ria Aveiro (LTER site) participation in the LTER-Europe Marine-and-Transitional-Waters Task Force, whose main goal is to foster interactions among the LTER-Europe Marine-and-Transitional-Waters sites, for an active contribution to the LTER-Europe network. A.I.Sousa coordinated the project MARSH-C-LEVEL (CNRS/OHMI-2015), wherein, in the scope of the global trend of climate change and sea level rise, the role of Baixo Vouga Lagunar (Ria Aveiro) saltmarshes on carbon storage was assessed, and the effects of sea level rise on their carbon storage capacity as an ecosystem service was anticipated.

Lillebo
Ana Isabel Lillebø is a Principal Researcher at the Department of Biology and CESAM, University of Aveiro and PI of CESAM’s Environmental Biology and Health Research Line. She holds a PhD in Biology (2001), University of Coimbra (Portugal). She is a well-established researcher in Coastal Ecosystems with special emphasis on: Environmental status and Management; Environmental Chemistry and Anthropogenic impacts; EU Policies and Ecosystem Services; with contributions to more than 100 communications, 25 book chapters and 79 ISI-indexed papers (h-index=23; w-index=7), including several papers on Ria de Aveiro. She has coordinated (LAGOONS, EU/FP7) and acts as case study leader (AQUACROSS, EU/H2020) in international projects having Ria de Aveiro coastal lagoon as national case study. She has act as coordinator (MARMER, FCT funded) and as UA team leader (ADAPT-MED (EU/FP7/ CIRCLE-MED Era Net) having the Baixo Vouga Lagunar as case study. Regarding additional research experience in the Baixo Vouga Lagunar area, she is currently a team member of the MARSH-C-LEVEL, HALOFOOD and RESTORE, all funded by CNRS/INEE, via OHMI.
