...Till S. Harter; Christian Damsgaard; Matthew D. Regan ABSTRACT The gill is the primary site of ionoregulation and gas exchange in adult teleost fishes. However, those characteristics that benefit diffusive gas exchange (large, thin gills) may also enhance the passive equilibration of ions and water...

... such as D. magna are well known to be more sensitive than adults to toxicants ( Mohammed, 2013 ). The nuchal organ is the primary means for pH and ionoregulation before development of the gills, gut and renal organs, and further studies of this tissue may aid identification of the effects of toxicants...

We used Ramsay assays and measured secreted fluid ion concentrations with ion-selective microelectrodes to assess temperature effects on fluid, Na + and K + secretion following thermal acclimation. As predicted, the Malpighian tubules of CA flies maintained K...

This study is the first to show that fish behaviourally exploit their surroundings to enhance their ionoregulation during digestion, and to pinpoint the novel role of dietary calcium and sodium in shaping this behaviour. We conclude that in order to resolve physiological disturbances in ion...
