Predicting gear used in a multi-gear coastal fleet
Leitão, Pedro; Campos, Aida; Castro, MargaridaKnowledge of the gear used in multi-gear fisheries is crucial for supporting fisheries management. Still, the high complexity and lack of data in the Portuguese multi-gear coastal fleet compromise this task. The present study developed a method to predict main fishing gear used in each fishing trip for the Portuguese multi-gear coastal fleet based on landing records (species caught, port, and month of landing)....
The Involuntary-To-Voluntary Hospitalization Transition and the Risk of Psychia...
Castro, Margarida; Tavares Coelho, Joana; Ferreira, Ana Rita; Salgado, HenriqueIntroduction: Involuntary hospitalization of a patient with a mental disorder is broadly defined as the admission to an inpatient unit without the patient’s consent. Literature suggests that involuntary hospitalizations are associated with low levels of treatment satisfaction, avoidance of mental health care, and an increased risk of emergency involuntary re-hospitalization. Despite being a lifesaving treatment...
Caminhando para uma Ciência Aberta: Uma abordagem estatística a partir da criaç...
Arias, Ivan; Castro, MargaridaNos dias de hoje, a difusão de novos meios facilitou a proliferação de dados científicos, que podem ser divulgados graças a novas técnicas de tratamento da informação. Visa-se, neste artigo, a partir do fluxo de trabalho que se estabelece entre dados abertos e ciência de dados, analisar resumos gerados de forma manual e de forma automática em termos estatísticos. Assim, avaliam-se novas possibilidades de tornar...
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...
Methods and products for the conservation of vandalized urban art murals
Macchia, Andrea; Castro, Margarida; Curbelo, Claudia; Rivaroli, Laura; Capriotti, Sara; Vieira, Eduarda; Moreira, Patrícia; Ruffolo, Silvestro AntonioThe possibility of contemporary mural paintings to be “tagged” by vandals, with spray and/or markers, represents a serious problem for the conservation of urban art. The present study aims to define the applicability of a protective coating on murals’ surface to preserve them against vandalism. The research has been focused on anti-graffiti products currently used in the field of cultural heritage conservation....
Influence of wind, rainfall, temperature, and primary productivity, on the biom...
Bento De Almeida, Joana Maria; Gaspar, Miguel; Castro, Margarida; Rufino, Marta M.Coastal bivalve populations are characterized by large temporal fluctuations, driven by recruitment success dependent on environmental conditions. The present study evaluated the relationship of rainfall, chlorophyll-α, sea surface temperature (SST) and wind, with the biomass of four commercial bivalve species (Spisula solida, Donax trunculus, Chamelea gallina and Ensis siliqua) that occur both along the Barlav...
Modelling the impact of deep-water crustacean trawl fishery in the marine ecosy...
Angeles Torres, Maria; Fonseca, Paulo; Erzini, Karim; Borges, Teresa C.; Campos, Aida; Castro, Margarida; Santos, Jorge Manuel BastosThe concentration of the population in coastal regions, in addition to the direct human use, is leading to an accelerated process of change and deterioration of the marine ecosystems. Human activities such as fishing together with environmental drivers (e.g. climate change) are triggering major threats to marine biodiversity, and impact directly the services they provide. In the South and Southwest coasts of Po...
Small-scale coastal fisheries in European Seas are not what they were: Ecologic...
Lloret, Josep; Cowx, Ian G.; Cabral, Henrique; Castro, Margarida; Font, Toni; Gonçalves, Jorge M.S.; Gordoa, Ana; Hoefnagel, Ellen; Matić-Skoko, SanjaCoastal, small-scale fisheries (SSF), whether artisanal (professional) or recreational, represent important socioeconomic activities across Europe that are currently undergoing a number of changes. This paper reviews and analyses the drivers of these changes, and makes recommendations for the future management of SSF. From the biological standpoint, the use of fishing gears that actively select certain species,...
Preliminary results on the use of semi-floating shrimp traps for the striped so...
Eichert, Moritz; Campos, Aida; Fonseca, Paulo; Henriques, Victor; Castro, MargaridaThe present study provides an account of an experimental survey aiming at the evaluation of the catchability of the striped soldier shrimp, Plesionika edwardsii, using semi-floating shrimp traps off the Algarve coast (southern Portugal). Currently, this species is not targeted by the crustacean bottom trawl fleet, and preliminary results on product value suggest that this may become an economically viable new f...
Effects of reallocating fishing effort from trawling to creels in a Norway lobs...
Eichert, Moritz; Campos, Aida; Fonseca, Paulo; Lopes, Pedro; Marques, Lino; Castro, MargaridaThe consequences of reallocating fishing effort from trawling to creels in an area off the West coast of Portugal for the operation of the trawl fleet, as well as on the population dynamics and the global catch value for a high valued species, the Norway lobster (Nephrops norvegicus) are evaluated. The results suggest that only small portions of the area of interest are used by the trawl fleet, opening the poss...
