Invasive dynamics of the signal crayfish Pacifastacus leniusculus in a protecte...
Carvalho, Francisco; Alves, Henrique; Pascoal, Cláudia; Castro, Paulo; Miranda, Fernando Jorge Veloso; Teixeira, Amílcar; Cássio, FernandaInvasive species have been drivers of biodiversity loss and functional changes in aquatic ecosystems, including in protected areas. Therefore, monitoring population invasion dynamics and biological traits is fundamental to better understand their ecological and economic impacts and for management actions development. We followed signal crayfish (Pacifastacus leniusculus) invasion in Rabaçal River upper reach at...
The Wave-Memory Interpretation of Quantum Mechanics
Castro, PauloPresent quantum mechanics has been a source of puzzlement since its inception in 1927. The theory has been undoubtedly successful predicting results in a large number of experimental situations. However, its heavy epistemological legacy, coming from the initial ideas of Niels Bohr about complementarity and about the possibility for physical description, has turned quantum mechanics in a kind of ontological blac...
Pilot Wave Theory in the Twenty-First Century
Castro, Paulo; W. M. Bush, John; Croca, José R.This book is the result of the International Conference on Advances in Pilot Wave Theory, hosted by the Centre for Philosophy of Sciences of the University of Lisbon (CFCUL), Portugal, held from 26 to 30 July 2021 (International Conference on Advances in Pilot Wave Theory—Concurrently Hosting Hydrodynamic Quantum Analogs HQA-2021 n.d.; Advances in Pilot Wave Theory & HQA2021—YouTube n.d.). The conference concur...
The silent extinction of freshwater mussels in Portugal
Lopes-Lima, Manuel; Reis, Joaquim; Alvarez, Maria G.; Anastácio, Pedro M.; Banha, Filipe; Beja, Pedro; Castro, Paulo; Gama, Mafalda; Gil, Maria G.Freshwater mussels are one of the most threatened animal groups in the world. In the European Union, threatened and protected mussel species are not adequately monitored, while species considered to be common and widespread receive even less attention. This is particularly worrying in the Mediterranean region, where species endemism is high and freshwater habitats are severely affected by water scarcity. In the...
Interspecific differences in the physiological condition of native freshwater m...
Modesto, Vanessa; Ilarri, Martina; Castro, Paulo; Carvalho, Francisco; Cavalheri, Thais; Lopes-Lima, Manuel; Teixeira, Amilcar; Ozorio, Rodrigo O. A.The Asian clam Corbicula fluminea has been widely introduced into aquatic ecosystems and may impact the physiological condition and survival of native freshwater mussels. However, very few studies have evaluated this issue quantitatively. To fill this gap, manipulative field experiments were performed to assess two possible mechanisms of impact on native mussels: (i) interspecific interactions, and (ii) C. flum...
Vantagens de Participação no Programa Nacional de Avaliação Externa da Qualidad...
Ventura, Catarina; Cardoso, Ana; Correia, Helena; Cordeiro, Marina; Castro, Paulo; Pereira, Edna; Faria, Ana PaulaIntrodução: O Programa Nacional de Avaliação Externa da Qualidade (PNAEQ) foi implementado no Instituto Nacional de Saúde Doutor Ricardo Jorge, Portugal, em 1978. A participação é voluntária, e permite monitorizar e implementar a melhoria da qualidade analítica, e de um modo independente, garantir a qualidade dos serviços prestados. Objetivo: Apresentação das vantagens que a participação nos programas de Avalia...

A roadmap for the conservation of freshwater mussels in Europe
Sousa, Ronaldo Gomes; Zając, Tadeusz; Halabowski, Dariusz; Aksenova, Olga V.; Bespalaya, Yulia V.; Carvalho, Francisco; Castro, Paulo; Douda, KarelEurope has a long history of human pressure on freshwater ecosystems. As pressure continues to grow and new threats emerge, there is an urgent need for conservation of freshwater biodiversity and its ecosystem services. However, whilst some taxonomic groups, mainly vertebrates, have received a disproportionate amount of attention and funds, other groups remain largely off the public and scientific radar. Freshw...
Computadores, matemática e significado
Castro, Paulotravés do computador é possível aceder graficamente a realidades matemáticas de outra forma inacessíveis. Sugere-se que a aplicação de uma didáctica significativa, no âmbito da matemática experimental, permite aos estudantes reflectir sobre questões fundamentais da realidade. Sugere-se que o resultado dessa aprendizagem não formal da matemática permite a construção de referências extensíveis à vida quotidiana, ...
Trophic niche overlap between native freshwater mussels (Order: Unionida) and t...
Modesto, Vanessa; Dias, Ester; Ilarri, Martina; Lopes-Lima, Manuel; Teixeira, Amílcar; Varandas, Simone; Castro, Paulo; Antunes, CarlosFreshwater mussels (Order Unionida) are highly threatened. Interspecific competition for food sources with invasive alien species is considered to be one of the factors responsible for their decline because successful invaders are expected to have wider trophic niches and more flexible feeding strategies than their native counterparts. In this study, carbon (δ13C: 13C/12C) and nitrogen (δ15N: 15N/14N) stable is...
