Mapping saltmarsh vertical distribution communities in southern Portugal using ...
Martins, Márcio; Parreira, Filipe; Ito, Paula; Santos, Rui; Gotha, Simon von sachsen-Coburg Und; Barrena de los Santos, CarmenSaltmarshes, transitional coastal habitats between terrestrial and marine ecosystems, offer crucial ecological benefits, including coastal protection, biodiversity enhancement, water purification and carbon sequestration. However, saltmarsh areas are shrinking, primarily due to human activities. Traditional monitoring approaches for saltmarsh coverage are often costly and restricted in spatial scope, prompting ...
Seagrasses in coastal wetlands of the Algarve region (southern Portugal): past ...
Ito, Paula; Martins, Márcio; von Sachsen-Coburg und Gotha, Simon; Santos, Rui; Barrena de los Santos, CarmenThe global biodiversity crisis urges to update the distribution maps of natural habitats, especially those that are in rapid decline and play a key role in ecosystem functioning, such as seagrasses. In Portugal, seagrass meadows have declined substantially since the 1980s and are considered one of the most endangered marine habitats. Here we aimed to 1) compile records on the distribution and area extent of sea...
Research trends on visitor’s intra-attraction spaciotemporal behaviour: a liter...
Martins, Márcio; Esteves, Elsa TavaresThe space-time behaviour of visitor´s, when investigated and understood, can provide the development of marketing strategies, better management of tourist attractions, and gather information about experiences and emotions experienced in destinations, among others. This study aims to present and discuss the contribution of research on visitors’ space-time behaviour at intra-attraction level, stressing some theor...
Sedimentary organic carbon and nitrogen sequestration across a vertical gradien...
Barrena de los Santos, Carmen; Egea, Luis G.; Martins, Márcio; Santos, Rui; Masqué, Pere; Peralta, Gloria; Brun, Fernando G.; Jiménez-Ramos, RocíoCoastal wetlands are key in regulating coastal carbon and nitrogen dynamics and contribute significantly to climate change mitigation and anthropogenic nutrient reduction. We investigated organic carbon (OC) and total nitrogen (TN) stocks and burial rates at four adjacent vegetated coastal habitats across the seascape elevation gradient of Cádiz Bay (South Spain), including one species of salt marsh, two of sea...
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 ...
Seagrass meadows improve inflowing water quality in aquaculture ponds
de los Santos, Carmen B.; Olivé, Irene; Moreira, Márcio; Silva, André; Freitas, Cátia; Araújo Luna, Ravi; Quental-Ferreira, Hugo; Martins, MárcioWater quality is critical for fish health in aquaculture production. In flow-through systems, the inflowing water normally requires quality controls and treatments for being supplied from coastal water bodies that can be polluted by nutrients, suspended solids, and microorganisms. Here we assess how seagrass meadows benefit aquaculture systems through the provision of ecosystem services (water filtration, biolo...
Ocean literacy to mainstream ecosystem services concept in formal and informal ...
Barracosa, Helena; de los Santos, Carmen B.; Martins, Márcio; Freitas, Cátia; Santos, RuiThe concept of ecosystem services (ES) emerges as strategic to explain the influences that the ocean, and in particular coastal ecosystems, have on us and how we influence them back. Despite being a term coined several decades ago and being already widespread in the scientific community and among policy-makers, the ES concept still lacks recognition among citizens and educators. There is therefore a need to mai...
