Travar a perda de pradarias marinhas para proteger o turismo na Ria Formosa
Martins, Irene; Guerra, Alexandra; Moreira, Alexandre; Alves, Fátima; Rosa, Rosário; Vidal, Diogo Guedes; Marta-Almeida, Martinho; Ramos, SandraEste policy brief apresenta e sintetiza resultados científicos obtidos com modelos numéricos aplicados ao sistema lagunar da Ria Formosa, avaliando a resposta do sistema sob cenários de alterações climáticas e de perda/degradação de habitat de pradarias marinhas, e identificando as principais implicações para a provisão de serviços de ecossistema com relevância direta para o turismo na região. Os resultados for...

Effect of warming on European green crab (Carcinus maenas) populations from lar...
Monteiro, João Nuno; Ovelheiro, Andreia; SORDO, LAURA; Palma, Jorge; Pinto, Miguel; Teodosio, Maria; Leitão, FranciscoUnderstanding the effects of climate change on the physiology of marine species, particularly during their early life stages (larvae and juveniles), is essential for predicting population dynamics. Carcinus maenas is a widely distributed species of significant ecological and economic importance. This experimental study investigates the effects of warming on the early life stages of the European green crab, C. m...
Collaborative bottom-up trust missions: a perspective on long-term strategies w...
Pelegrí, Josep L.; Bojanić, Natalia; Whyte, David; Pinto, Patrícia; Annasawmy, Pavanee; Burgues, Itziar; Bušelić, Ivana; Carbajal, Maria ElenaThe environmental and climate crises are linked to rising global inequity. Because of its centrality in the living Earth, the Ocean represents a unique opportunity to restore equity, engaging society through harmony with Nature. The United Nation's Ocean Decade and European Union's Mission Ocean and Waters recognize this centrality, but have focused on top-down actions. Here, we advocate for collaborative Trust...
Predicting climate change impacts on marine fisheries, biodiversity and economy...
Leitão, Francisco; Cánovas, FernandoThe vulnerability of fisheries to climate change (CC) is driven by exposure factors that can affect species and fisheries differently at regional level. Ecological and socioeconomic consequences of climate change were assessed by evaluating a set of species (N = 53), caught by Portuguese fleet, that are likely to be affected by changes in oceanographical conditions (climatic scenarios RCP4.5 and RCP8.5) by the ...
Biological traits and population dynamics for sustainable harvesting of Carcinu...
Monteiro, João Nuno; Ovelheiro, Andreia; Maia, Francisco; Teodosio, Maria; Leitão, FranciscoResearch focusing on the biological patterns and population dynamics of Carcinus maenas has not been conducted for the purpose of fishery management along the European coastal systems. This has led to the implementation of fisheries management policies without scientific considerations, adversely affecting fishery profitability. To addrees this gap, we studied the crab species' population dynamics, reproductive...
Boating tourism and fishing Interactions: a social network analysis using AIS data
Ramos, Jorge; Drakeford, Benjamin; Costa, Joana; Leitão, FranciscoBoating tourism in coastal-maritime areas often overlaps spatially and temporally with other economic activities, such as fishing, leading to complex interactions. These interactions can create opportunities for positive cooperation or generate conflicts that pressure natural resources and stakeholders. The aim of this study is to show whether or not there is evidence of interactions between fishing (nf = 43) a...
Impact and size selectivity of fishing gears used in estuarine crab fisheries
Monteiro, João Nuno; Ovelheiro, Andreia; Teodosio, Maria; Leitão, FranciscoCrustacean fisheries have expanded in the last decade due to the high economic value of the species. However, estuarine crustacean fisheries remain poorly studied compared with marine crustacean fisheries. In Portugal, the European green crab ( Carcinus maenas) may become increasingly important for the fishing industry and seafood production in general, especially in the current context of overexploitation of e...
Tracking tourism waves: insights from automatic identification system (AIS) dat...
Ramos, Jorge; Drakeford, Benjamin; Costa, Joana; Madiedo Camelo, Ana Maria; Leitão, FranciscoAbstract: The demand for maritime–coastal tourism has been intensifying, but its offerings are sometimes limited to a few activities. Some of these activities do not require specific skills or certifications, while others do. This study aimed to investigate what type of activities are carried out by tourism and recreational vessels in the coastal area of the central Algarve (Portugal). To this end, data from th...
Ichthyofaunal community assemblage and spatiotemporal patterns in the Bons Sina...
Mocuba, Jeremias; Florêncio dos Santos Costa, Eudriano; Teodosio, Maria; Leitão, FranciscoUnderstanding the ichthyofaunal assemblage of estuarine and adjacent coastal ecosystems is important for managing fishery resources and implementing conservation actions. This study explored the structure, diversity, and spatial-temporal variations of the ichthyofauna in the Bons Sinais Estuary (Mozambique) and the influence of environmental parameters. Fish sampling was conducted in the lower, middle, and uppe...
