Repercussions of adjuvant-induced arthritis on body composition, soleus muscle,...
Pita, L. M.; Spadella, M. A.; Montenote, M. C.; Oliveira, P. B.; Chies, A. B.Made available in DSpace on 2022-04-29T08:45:26Z (GMT). No. of bitstreams: 0 Previous issue date: 2020-01-01; Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES); Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP); This study investigated the repercussions of adjuvant-induced arthritis (AIA) on body composition and the structural organization of the soleus and cardiac muscles, includi...
Phytoplankton distribution and physical processes off NW Iberia during two cons...
Oliveira, P. B.; Amorim, F. N.; Dubert, J.; Nolasco, R.; Moita, TeresaThis work presents the results of two oceanographic surveys conducted off NW Iberia during successive summer upwelling seasons, aiming at the identification of the physical processes underlying the phytoplankton distribution in the area. Mooring (ADCP and thermistors) and ship-based CTD-F observations corroborate previous results that wind-driven upwelling circulation, (sub)mesoscale eddies and the stratificati...
First representation of the trophic structure and functioning of the Portuguese...
Veiga-Malta, T.; Szalaj, D.; Angelico, M. M.; Azevedo, M.; Farias, I; Garrido, S.; Lourenco, S.; Marçalo, Ana; Marques, V; Moreno, A.; Oliveira, P. B.In this study, we analysed the structure and functioning of the Portuguese continental shelf ecosystem and investigated the role of sardine Sardina pilchardus using the Ecopath massbalance approach. An Ecopath model was configured to represent the continental shelf waters in the period 2006-2009. The model showed that biomass was concentrated in low and intermediate trophic levels as in other upwelling areas. S...
Validation of standard and alternative satellite ocean-color chlorophyll produc...
Sá, Carolina; D'Alimonte, Davide; Brito, A.; Kajiyama, T.; Mendes, C. R.; Vitorino, J.; Oliveira, P. B.; da Silva, J. C. B.; Brotas, V.Chlorophyll a concentration (Chl) product validation off theWestern Iberian coast is here undertaken by directly comparing remote sensing data with in situ surface reference values. Both standard and recently developed alternative algorithms are considered for match-up data analysis. The investigated standard products are those produced by the MERIS (algal 1 and algal 2) and MODIS (OC3M) algorithms. The alterna...
Near shore oceanographic conditions off SW Portugal in summer 2006 and 2007 fro...
Oliveira, P. B.; Angélico, M. M.; Fernandes, J.; Castro, J. J.; Cruz, T.Data from two successive summers are used to characterize the near shore oceanographic conditions south of cape Sines in the SW Portuguese coast. The observed time evolution of the satellite-derived sea surface temperature (SST) and chlorophyll ([Chl]) patterns show that the near shore patterns are very sensitive to the intensity and temporal structure of the upwelling favourable winds. Stronger and more variab...
Diet and feeding intensity of sardine Sardina pilchardus: correlation with sate...
Garrido, Susana; Ben-Hamadou, Radhouan; Oliveira, P. B.; Cunha, M. E.; Chicharo, Maria Alexandra; Van der Lingen, C. D.Spatio-temporal variability of the diet of sardine Sardina pilchardus off Portugal was examined through analysis of the stomach contents of fish collected every 14 d from the west and south of Portugal during 2003/2004. Dietary composition of the modal sardine length class was assessed by determining the frequency of occurrence and carbon content of identified prey, and these 2 parameters were combined to estim...
Physical-biological interactions in the life history of small pelagic fish in t...
Santos, A. Miguel P.; Chicharo, Maria Alexandra Teodosio; Santos, Antonina dos; Moita, Teresa; Oliveira, P. B.; Peliz, A.; Re, P.This paper reviews relevant investigations conducted in the Western Iberia Upwelling Ecosystem (WIUE) on the dynamics of small pelagic fish (SPF), its relationship to climate changes and processes related to the ‘ocean triad’ (enrichment, concentration, transport/retention). In the last decades, a decline in the productivity of several SPF species (e.g., sardine and horse mackerel) was observed in the WIUE, whi...
Greenhouse climate management and control systems
Cunha, J. B.; Ruano, Antonio; Oliveira, P. B.; Couto, C.The technologies used in greenhouse production systems have developed considerably during the last decade. These improvements have taken place in several areas, such as the development of new building techniques and actuating equipments, modelling of the plant physiological processes and of the greenhouse climate, among many others. Nowadays, due to economic and environmental requirements, there is still a dema...
