A research blueprint: plant trait responses to stress and effects on blue carbo...
Gillis, Lucy Gwen; Viana, Inés G.; de los Santos, Carmen B.Wetland plants form blue carbon ecosystems, which are key for climate change mitigation yet threatened by multiple local and global stresses. The capacity of blue carbon ecosystems to store large amounts of carbon relies on ecological processes, many of them regulated by plant traits that are shaped by the stress that plants encounter.This manuscript provides a perspective to investigate the effects of stress o...
Relatório Científico I: Avaliação dos ecossistemas de carbono azul em Portugal ...
Santos, Rui; Ito, Paula; de los Santos, Carmen B.Por ocasião da Conferência do Oceano das Nações Unidas, que decorreu em Lisboa em junho de 2022, a Fundação Calouste Gulbenkian lançou o projeto Gulbenkian Carbono Azul, em parceria com o Centro de Ciências do Mar (CCMAR) da Universidade do Algarve e a Associação Natureza Portugal em associação com a WWF – World Wide Fund for Nature (ANP|WWF), com o objetivo de investigar as informações disponíveis para mapear ...
Global dataset of soil organic carbon in tidal marshes
Maxwell, Tania L.; Rovai, André S.; Adame, Maria Fernanda; Adams, Janine B.; Álvarez-Rogel, José; Austin, William E. N.; Beasy, Kim; Boscutti, FrancescoTidal marshes store large amounts of organic carbon in their soils. Field data quantifying soil organic carbon (SOC) stocks provide an important resource for researchers, natural resource managers, and policy-makers working towards the protection, restoration, and valuation of these ecosystems. We collated a global dataset of tidal marsh soil organic carbon (MarSOC) from 99 studies that includes location, soil ...
Loss of surficial sedimentary carbon stocks in seagrass meadows subjected to in...
Román, Marta; de los Santos, Carmen B.; Román, Salvador; Santos, Rui; Troncoso, Jesús S.; Vázquez, Elsa; Olabarria, CeliaSeagrass carbon stocks are vulnerable to physical disturbance. We assessed the effect of clam harvesting on the organic carbon (Corg) stocks in surface sediments in four intertidal Zostera noltei meadows on the Iberian Atlantic coast (Spain and Portugal), by comparing undisturbed and harvested areas. We also monitored the spatial cover of the meadows throughout the growing season. Sedimentary Corg content and C...
Influence of seagrass meadows on nursery and fish provisioning ecosystem servic...
Erzini, Karim; Parreira, Filipe; Sadat, Zineb; Castro, Margarida; Bentes, Luis; Coelho, Rui; Gonçalves, Jorge Manuel Santos; Lino, Pedro G.This study is the first to evaluate the fish provisioning services of a whole transitional landscape (Ria Formosa lagoon, Portugal), in parallel with the enhancement of growth, survival and production of single cohorts of the most important commercial fish species by vegetated and unvegetated sub-tidal habitats. Based on monthly beach seine samples, total density and biomass of 96 species of fishes were 1.89 an...
Sedimentary organic carbon and nitrogen stocks of intertidal seagrass meadows i...
Casal-Porras, Isabel; de los Santos, Carmen B.; Martins, Márcio; Santos, Rui; Pérez-Lloréns, J. Lucas; Brun, Fernando G.Seagrass meadows, through their large capacity to sequester and store organic carbon in their sediments, contribute to mitigate climatic change. However, these ecosystems have experienced large losses and degrada-tion worldwide due to anthropogenic and natural impacts and they are among the most threatened ecosystems on Earth. When a meadow is impacted, the vegetation is partial-or completely lost, and the sedi...
Vertical intertidal variation of organic matter stocks and patterns of sediment...
de los Santos, Carmen B.; Lahuna, François; Silva, André; Freitas, Cátia; Martins, Márcio; Carrasco, A. Rita; Santos, RuiTidal coastal wetlands, common home to seagrass and salt marshes, are relevant carbon sinks due to their high capacity to accumulate and store organic carbon in their sediments. Recent studies demonstrated that the spatial variability of this organic carbon within the same wetland system can be significant. Some of the environmental drivers of this spatial variability remain understudied and the selection of th...
Carbon and nitrogen stocks and burial rates in intertidal vegetated habitats of...
Martins, Márcio; de los Santos, Carmen B.; Masqué, Pere; Carrasco, A. Rita; C. Veiga-Pires, C.; Santos, RuiCoastal vegetated ecosystems such as saltmarshes and seagrasses are important sinks of organic carbon (OC) and total nitrogen (TN), with large global and local variability, driven by the confluence of many physical and ecological factors. Here we show that sedimentary OC and TN stocks of intertidal saltmarsh (Sporobolus maritimus) and seagrass (Zostera noltei) habitats increased between two- and fourfold along ...
Long-term effects of elevated CO2 on the population dynamics of the seagrass Cy...
Mishra, A. K.; Cabaço, S.; de los Santos, Carmen B.; Apostolaki, E.T.; Vizzini, S.; Santos, R.Population reconstruction techniques was used to assess for the first time the population dynamics of a seagrass, Cymodocea nodosa, exposed to long-term elevated CO2 near three volcanic seeps and compared them with reference sites away from the seeps. Under high CO2, the density of shoots and of individuals (apical shoots), and the vertical and horizontal elongation and production rates, were higher than at the...
Microplastics in commercial bivalves harvested from intertidal seagrasses and s...
Cozzolino, Lorenzo; de los Santos, Carmen B.; Zardi, Gerardo I.; Repetto, Luca; Nicastro, KatyThrough seafood consumption, microplastic (MP) pollution is potentially threatening human health. Commercial bivalves in particular are a cause of major concern because their filter-feeding activity directly exposes them to MP in the water column and they are then ingested by humans. Here, we provide a quantitative and qualitative baseline data on MP content in the soft tissues of three commercially important b...
