Life Águeda – Restoring River Connectivity For Migratory Fish In The Vouga Rive...
Pedro, S.; Alexandre, CM; Mateus, CS; Quintella, BR; Boavida-Portugal, J; Lança, M.J.; Belo, AF; Pereira, E; Rato, AS; Oliveira, IC; Silva, SPresentation of the results of the work carried out on this subject in the Vouga River basin
Multiple non contiguous copy gains and a terminal loss in 8q24 identified in a ...
Serafim, S.; Pedro, S.; Marques, B.; Tarelho, A.R.; Ferreira, C.; Simao, L.; Viegas, M.; Silva, M.; Alves, C.; Mourinha, V.; Ferreira, A.; Correia, H.Objectives: Chromosomal microarray analysis (CMA) is the recommended genetic test in pregnancies with ultrasound abnormalities but in some cases karyotype may still be needed to clarify the underlying mechanism of complex rearrangements. Here we report the case of a fetus from a healthy 24-year-old G1P0 woman, with a low risk for common aneuploidies in the 1st trimester prenatal screening but referred for CMA a...
LIFE Agueda—Gaining Habitat for Migratory Fish in the Vouga River Basin
Pedro, S.; Alexandre, C.M.; Mateus, C.S.; Quintella, B.R.; Lança, M.J.; Belo, A.F.; Pereira, E.; Rato, A.S.; Oliveira, I.; Silva, S.; Almeida, P.R.Habitat loss and overfishing are the most significant threats to diadromous fish, most of them of high socioeconomic and conservationist importance, such as Alosa alosa, Alosa fallax, Petromyzon marinus and Anguilla anguilla. The main objective of the LIFE Águeda project (LIFE16 ENV/PT/000411) is the removal of hydro-morphological pressures towards the reestablishment of conditions for a good ecological status,...
Temporal patterns of the catadromous thinlip grey mullet migration in freshwater
Pereira, E.; Quintella, B.; Lança, M.J.; Alexandre, C.; Mateus, C.; Pedro, S.; Belo, A.; Rato, A.; Quadrado, M.; Baptista, C.; Telhado, A.Abstract The thinlip grey mullet (Chelon ramada Risso, 1827) is a catadromous fish that per forms massive migrations to freshwater habitats for feeding purposes that can assume a structuring role on riverine ecology due to the biomass involved in these movements. Seasonal movements of thinlip grey mullet through a vertical slot fish pass located in River Mondego (Portugal) were continuously monitored between 20...
Catches, sales and discards: Small-scale fisheries in a Portuguese Marine park
Castro, N.; Romão, F.; Castro, J. J.; Pereira, T. J.; Pedro, S.; Viegas, V.; Costa, J. L.The natural park ‘‘Parque Natural do Sudoeste Alentejano e Costa Vicentina’’ (PNSACV; SW coast of continental Portugal) includes a recently implemented marine protected area of 2 km along its coast, where important, although not quantified, small-scale commercial fisheries are carried out. Conservation measures were implemented since 2011. The present study aimed to estimate the fishing effort, catches, discard...
Chemical and Microbiological Contamination in Limpet (Patella spp.) of the Port...
Pedro, S.; Cardoso, C.; Caetano, J.; Mourato, Miguel; Lourenço, H.M.Coastal production areas can be impacted by anthropogenic contamination from urban, agro-industrial and leisure activities. Some contaminants, such as chemical substances might also have a telluric origin. Non filter feeding univalve mollusks, such as limpets, which are collected in rocky shores either for sale or for auto-consumption, are very appreciated in Portugal, but have been excluded from provisions on ...
Conservation and management actions for migratory fish in the Vouga river basin
Mateus, Catarina; Pedro, S.; Quintella, B.R.; Alexandre, C. M.; Lança, M.J.; Pinheiro-Alves, T.; Pereira, E.; Belo, A.D.F.; Silva, A.F.; Marques, J.P.Habitat loss and overfishing are the most significant threats to diadromous fish, most of them of high socioeconomic and conservationist importance, like, for instance, Alosa alosa, A. fallax, Petromyzon marinus and Anguilla anguilla. Pilot restoration actions aiming to recover diadromous populations were conducted for the past 20 years in the Mondego river basin, materialized by the construction of seven fish ...
Diadromous fish in Portugal: status, threats and management guidelines
Almeida, P.R.; Quintella, B.R.; Mateus, C.S.; Alexandre, C.M.; Pedro, S.Diadromous fish evolved in a way to use two completely different environments during their life-cycle (i.e. river and sea), being divided in anadromous (e.g. sea lamprey, shads) and catadromous (e.g. eel, thinlipped grey mullet) species, if their reproduction occurs, respectively, in freshwater or marine environments. In Portugal, the high commercial value associated with these species makes them primary target...
Prenatal diagnosis of mosaic ring chromosome 16 - a rare event with uncertain p...
Brito, F.; M. Silv, M.; Alves, C.; Ferreira, C.; Serafim, S.; Simão, L.; Marques, B.; Pedro, S.; Tarelho, A.; Furtado, J.; Lopes, P.; Silva, N.Ring chromosomes are rare cytogenetic findings (prenatal frequency ~ 0.0075%) often associated with an abnormal phenotype, depending of the chromosomal origin, genetic content and the presence of a mosaic. Supernumerary ring chromosome 16 [r(16)] is rarely observed and mosaicism makes the genotype/phenotype correlation difficult. We report a de novo mosaic r(16) detected after prenatal diagnosis in a woman refe...
47,XY,+del(X)(q21.31)/46,XY mosaicism in prenatal diagnosis - case report of a ...
Ferreira, C.; Tarelho, A.; Marques, B.; Serafim, S.; Pedro, S.; Ferreira, A.; Correia, H.OBJECTIVES: Aneuploidies involving the sex chromosomes are the most common anomalies in humans. In many cases these anomalies are present in mosaic and may involve either the whole chromosome or just part of it. These anomalies constitute a challenge in prenatal diagnosis because it is generally very difficult to establish a reliable genotype-phenotype correlation. Here we report a rare event of a mosaic in whi...
