Short-term versus long-term changes in the benthic communities of a small coast...
Félix, PM; Chainho, P; Costa, Jl; Correia, MJ; Chaves, ML; Medeiros, JP; Cabral, HN; Wouters, N; Bernardo, J; Costa, AM; Cristo, M; Silva, G; Azeda, CThe characteristic high variability and low predictability of coastal lagoons, due to strong changes in marine and freshwater inputs, make these ecosystems an interesting casestudy. The small Melides landlocked coastal lagoon in SW Portugal is a paradigmatic example, with a biological community highly stressed by these phenomena. Benthic macroinvertebrate samples were collected in 1998/99 and 2009 and each year...
Deciduoid Pleural Mesothelioma - a Rare Entity in a Young Woman
Santos, C; Gamboa, F; Fradinho, F; Pêgo, A; Carvalho, L; Bernardo, JDeciduoid Mesothelioma is a rare variant of epithelioid mesothelioma; it was initially thought that it only occurred in the peritoneum of young women and had nothing to do with asbestos exposure. However, since these early findings it has also been observed in the pleura and the pericardium, with possible association to asbestos. In general the prognosis is poor compared to epithelioid mesothelioma. 45 cases ha...
Inter-annual variations of macrobenthic communities over three decades in a lan...
Correia, M.J.; Costa, J.L.; Chainho, P.; Félix, P.M.; Chaves, M.L.; Medeiros, J.P.; Silva, G.; Azeda, C.; P. Tavares, P.; Costa, A.; Costa, A.M.Santo André is an enclosed brackish water coastal lagoon with temporary connections to the sea by a man-made channel. The exchange and mixture of saltwater and freshwater is irregular and the lagoon may show daily and seasonal fluctuations, but also long-term variation. Different benthic communities may be present along the annual cycle according to the magnitude of episodic freshwater and sea water inputs. In ...
Pós-Graduação, saberes e formação docente: uma análise das repercussões dos cur...
Zaidan,Samira; Caldeira,Anna Maria Salgueiro; Oliveira,Bernardo J.; Silva,Patrícia Gomes Carneiro daEste artigo analisa repercussões do mestrado e do doutorado na vida profissional de 305 egressos do Programa de Pós-Graduação em Educação da FaE-UFMG, no período 1977-2006. Por meio de um questionário, obtiveram-se informações relativas às atividades profissionais dos egressos. Os resultados foram analisados por decênios e mostram que a docência no ensino superior é a ocupação majoritária dos egressos. Os douto...
Speeds and stance of titanosaur sauropods: analysis of Titanopodus tracks from ...
González Riga,Bernardo J.Speed estimations from trackways of Titanopodus mendozensis González Riga and Calvo provide information about the locomotion of titanosaurian sauropods that lived in South America during the Late Cretaceous. Titanopodus ichnites were found at Agua del Choique, a newly discovered track site in the Loncoche Formation, Late Campanian-Early Maastrichtian of Mendoza, Argentina. This speed study follows the hypothesi...
Organizing pneumonia due to actinomycosis: an undescribed association
Alfaro, TM; Bernardo, J; Garcia, H; Alves, F; Carvalho, L; Caseiro-Alves, F; Robalo-Cordeiro, COrganizing pneumonia is a pathologic entity characterized by intra-alveolar buds of granulation tissue that can extend to the bronchiolar lumen. It is a non-specific finding reflecting a pattern of pulmonary response to aggression that can be cryptogenic or associated with several causes. Pulmonary actinomycosis is a rare infectious disease, of bacterial aetiology, and of difficult diagnosis. This disease usual...
Dispersal and coexistence of two non-native crayfish species (Pacifastacus leni...
Bernardo, J.M.; Costa, A.M.; Bruxelas, S.; Teixeira, AmílcarNE Portugal is one of the most isolated and low populated regions of Western Europe. Recently, two American crayfish species reached this area: signal crayfish Pacifastacus leniusculus coming from Spain and red swamp crayfish Procambarus clarkii in its northward expansion. The dispersion of both species was followed throughout the last decade in river Maçãs (Douro catchment). Our results support the hypothesis ...
Coexistência de duas espécies exóticas de lagostins (Pacifastacus leniusculus e...
Costa, A.M.; Bruxelas, S.; Bernardo, J.M.; Teixeira, AmílcarEm Portugal existia uma única espécie europeia de lagostim de água doce, Austropotamobius pallipes, o lagostim-de-patas-brancas, que se considera actualmente extinta no país. No nordeste de Portugal continental onde anteriormente ocorria esta espécie, os cursos de água estão actualmente a ser colonizados por duas espécies de lagostins norte americanos. Na década de 70, proveniente de Espanha onde foi intenciona...
Interacção entre duas espécies exóticas de lagostins (pacifastacus leniusculus ...
Teixeira, Amílcar; Costa, A.M.; Bernardo, J.M.; Bruxelas, S.; Nogueira, Mónica Sofia ReisNo rio Maçãs (bacia do Rio Douro), no Nordeste de Portugal, coexistem duas espécies de lagostins exóticos, o lagostim vermelho da Louisiana (Procambarus clarkii) e o lagostim sinal (Pacifastacus leniusculus). Para estudar o movimento e padrão de actividade de ambas as espécies foi desenvolvida uma experiência num espaço confinado (300 x 100 cm) e aplicada a técnica da PIT-telemetria (Passive Integrated Technolo...
Colonization and dispersal rates of two non-native crayfish species (Pacifastac...
Bernardo, J.M.; Costa, A.M.; Bruxelas, S.; Teixeira, AmílcarIn Europe, a generalized regression of the native crayfish was observed during the past decades. Simultaneously, several non-native species spread in most countries. In Portugal, the red swamp crayfish, Procambarus clarkii, is now occurring in most inland waters. The NE Portugal is one of the most isolated and low populated regions of Western Europe. Most rivers in these region present low levels of human impac...
