...Alexander M. Schreiber SUMMARY Flatfishes, such as flounder, are the world's most asymmetric vertebrates. It is unknown if the development of lateralized swimming behavior during metamorphosis is an adaptive response to bilaterally asymmetric eye positioning, or if this results from a vestibular...

...A. J. Ashworth; J. R. Banks; M. J. Brierley; R. J. Balment; C. R. McCrohan SUMMARY This study examined the electrical firing activity of neuroendocrine Dahlgren cells in the caudal neurosecretory system (CNSS) of the euryhaline flounder in vivo . Intracellular recordings revealed generally similar...

...M. J. Brierley; A. J. Ashworth; T. P. Craven; M. Woodburn; J. R. Banks; W. Lu; D. Riccardi; R. J. Balment; C. R. McCrohan SUMMARY The caudal neurosecretory system (CNSS) of the euryhaline flounder is involved in osmoregulatory responses underlying adaptation to seawater and freshwater. This study...

...M. J. Brierley; A. J. Ashworth; J. R. Banks; R. J. Balment; C. R. McCrohan SUMMARY Bursting activity in type 1 Dahlgren cells was studied using intra- and extracellular recording from an in vitro preparation of the caudal neurosecretory system of the euryhaline flounder. 45% of cells showed...

...Alex M. Schreiber; Jennifer L. Specker ABSTRACT Salinity tolerance changes during larval development and metamorphosis in the summer flounder ( Paralichthys dentatus ) and other teleosts. The physiological mechanisms responsible for osmoregulation during these early stages of development...

...M. Grosell; F. B. Jensen ABSTRACT Ion transport across isolated intestinal segments from the European flounder ( Platichthys flesus ) was studied with the primary aim of evaluating the mechanisms of nitrite (NO 2 − ) uptake and HCO 3 − excretion. A double-radiolabelling technique was applied...

...Y. R. Weaver; K. Kiessling; A. R. Cossins ABSTRACT The transport pathways mediating regulatory volume increase (RVI) and β-adrenergic responses in red cells of the European flounder Platichthys flesus have been investigated. Hypertonic treatment under a low- atmosphere led to a complete RVI...

...Steinar M. Thoroed; Margrethe Soergaard; Edward J. Cragoe, JR; Kjell Fugelli ABSTRACT Stimulation of flounder erythrocytes by noradrenaline under isosmotic conditions (330 mosmol kg -1 ) and physiological Na + concentration (113 mmol l -1 ) caused swelling of the cells. The EC 50 of this cell...

...S. M. Thoroed; K. Fugelli ABSTRACT 95 % of the Na + -independent influx of taurine in flounder erythrocytes at normal osmolality (330 mosmol kg −1 ) and 0.30 mmol l −1 taurine was mediated by a saturable system ( V max =0.689 nmol g −1 dry mass min −1 ; K m =0.47 mmol l −1 ). The influx...

...D. Burton; M. P. O’driscoll ABSTRACT Melanophores of winter flounder (Pseudopleuronectes americanus) subjected to repeated transfers between black and white backgrounds display pronounced enhancement of the rates of melanosome aggregation and dispersion. Melano-some aggregation in response...

...C. Louise Milligan; D. Gordon Mcdonald ABSTRACT A bolus injection of [ 14 C] lactate was used to measure lactate turnover rates at rest and during recovery from exhaustive exercise in coho salmon (Oncorhynchus kisutch) and starry flounder (Platichthys stellatus) . At rest, lactate turnover rate...

...H. Gesser; A. Mangor-Jensen ABSTRACT The twitch force of isolated electrically paced ventricular strips of flounder, Platichthys flesus L., increased after lowering the extracellular sodium chloride concentration by 50 mmol l −1 . This response was markedly reduced by replacing the sodium chloride...
