Daily oxygen consumption rhythms of Senegalese sole solea senegalensis (Kaup, 1...
Castanheira, F.; Martins, C. I. M.; Engrola, S.; Conceição, L. E. C.Senegalese sole is known to be a species with pronounced nocturnal feeding behaviour. However, as for most fish species, there is a lack of knowledge concerning the influence of such biological rhythmon metabolic rate. The aim of this study was to determine whether individual variation in routine and fed metabolic rate was affected by daily light–dark rhythms in juveniles of Senegalese sole. The individual oxyg...
Individual differences in metabolism predict coping styles in fish
Martins, C. I. M.; Castanheira, F.; Engrola, S.; Costas, B.; Conceição, L. E. C.Studies on metabolism usually rely on measurements of oxygen consumption obtained in respirometry chambers. Despite rigorous standardization there is still considerable interindividual variation in metabolic rates which is often ignored. Furthermore, housing in respirometry chambers implies handling and exposure to a new environment, conditions known to be a source of stress in animals. The extent of stress res...
Metabolic basis of growth variation in juvenile sole (Solea senegalensis, Kaup ...
Castanheira, F.Dissertação mest., Aquacultura e Pescas, Universidade do Algarve, 2009 ; The general aim of this study was to understand the underlying factors responsible for the individual variation in growth of juvenile Senegalese sole (Solea senegalensis). Senegalese sole is a species of high commercial value and high interest for aquaculture in Europe, therefore it would be important to understand these individual variat...
A fatal forensic intoxication with fenarimol: analysis by HPLC/DAD/MSD
Proença, P.; Marques, E. Pinho; Teixeira, H.; Castanheira, F.; Barroso, M.; Ávila, S.; Vieira, D. N.Fenarimol (Rubigan®) is a pyrimidine ergosterol biosynthesis inhibitor used as a systemic fungicide. The authors present a fatal fenarimol intoxication case analysed in the Forensic Toxicology Service of the National Institute of Legal Medicine. The results were used to compare two different HPLC techniques, regarding selectivity and sensitivity: an HPLC system with a diode array detector (DAD) and an HPLC syst...
