Socio-economic and ecological drivers and challenges: the sea urchin fishery of...
Jacinto, D; Mateus, D; Maresca, F; Correia, MJ; Mega Lopes, P; Alves, C; Silva, T; Castro, JJ; Cost, JL; Cruz, TSea urchin harvesting on the central coast of continental Portugal is a traditional activity well rooted in the littoral community. The rock-boring sea urchin, Paracentrotus lividus, is mostly harvested for its gonads by professional and recreational fishers. Recent and renewed interest in this marine resource has led to a first assessment of the local sea urchin population’s current status and the characteriza...
Pilot studies for stock enhancement of purple sea urchins (Paracentrotus lividu...
Correia, MJ; Mega Lopes, P; Santos, PM; Jacinto, D; Mateus, D; Maresca, F; Quintella, B; Cruz, T; Sílvia, L; Pombo, A; Costa, JLIn the framework of stock enhancement, field experiments were conducted between March and July 2021 in rocky shores of Central Portugal to test the usefulness of refuges and calcein marking for juvenile sea urchins releases. Individuals with 10–20 mm in test diameter were captured in nature and tagged through immersion in a calcein bath with a concentration of 150 mg L−1, during 48 hr. Artificial shelters were ...
Physical and chemical tagging methods for the sea urchin Paracentrotus lividus ...
Santos, PM; Quintella, B; Jacinto, David; Gomes, A; Saldanha, C; Lourenço, S; Lopes, P; Correia, MJ; Mateus, D; Cruz, T; Pombo, A; Costa, JLThe sea urchin Paracentrotus lividus (Lamarck, 1816) (Echinodermata: Echinoidea) is an important economic resource in Europe, but intense harvesting has led to the collapse of several natural populations. Echinoculture, associated with restocking and stock enhancement practices, is an alternative to this problem. In these procedures, reliable individual identification through tagging is a valuable source of inf...
Mercapturate Pathway in the Tubulocentric Perspective of Diabetic Kidney Disease
Gonçalves-Dias, C; Morello, J; Correia, MJ; Coelho, N; Antunes, A; Macedo, MP; Monteiro, E; Soto, K, et al.BACKGROUND: The recent growing evidence that the proximal tubule underlies the early pathogenesis of diabetic kidney disease (DKD) is unveiling novel and promising perspectives. This pathophysiological concept links tubulointerstitial oxidative stress, inflammation, hypoxia, and fibrosis with the progression of DKD. In this new angle for DKD, the prevailing molecular mechanisms on proximal tubular cells emerge ...
Impact of freshwater inputs on the spatial structure of benthic macroinvertebra...
Félix, PM; Correia, MJ; Chainho, P; Costa, JL; Chaves, ML; Cruz, T; Castro, JJ; Mirra, C; Domingos, I; Silva, ACF; Cancela da Fonseca, LLandlocked lagoons are naturally stressed environments. They are strongly influenced by freshwater input which not only varies naturally, but which is also impacted by anthropogenic activities. This study investigated the direct influence of freshwater discharges on the distribution patterns and abundance of benthic communities in two neighbouring landlocked coastal lagoons, assessing the whole system and the c...
Projecto Groundscene: biodiversidade de lagoas costeiras e respectivas bacias h...
Chainho, P; Félix, PM; Correia, MJ; Fernandes, CM; Costa, JL; Chaves, ML; Stigter, T; Hugman, R; Salvador, N; Costa, L; Domingos, I; Castro, J; Cruz, TNa União Europeia a Directiva Quadro da Água requer a avaliação do estado ecológico de todas as águas interiores (dulciaquícolas e de transição) e costeiras, incluindo os ecossistemas aquáticos superficiais cujo estado ecológico poderá estar dependente do estado das águas subterrâneas (AS). O estado ecológico em lagoas costeiras dependentes de AS depende das interacções AS - água doce superficial - água salgada...
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...
O Insucesso de Gravidez: Leitura Psicológica
Correia, MJCom este artigo pretende-se uma abordagem psicológica do insucesso de gravidez. Através de uma resenha bibliográfica define-se o conceito e aborda-se em primeiro lugar a sua etiologia dando particular ênfase aos factores de ordem psicológica. Num segundo momento destacam-se as diferentes formas de reacção emocional ao insucesso de gravidez relevando-se a situação de luto.
The role of abscisic acid and water relations in drought responses of subterran...
Socias, X; Correia, MJ; Chaves, M; Medrano, HThe role of water relations and abscisic acid (ABA) in the responses to drought were studied in a mediterranean forage crop, Trifolium subterraneum L. under field conditions. soil and plant water status, leaf gas exchange parameters, and xylem sap ABA content were determined at different times during a long-term soil drying episode in irrigated and droughted plants. The diurnal time-courses of these parameters ...
