... Osmoregulation Excretion Water absorption Scanning ion-selective electrode technique Springtails (Collembola) are a basal lineage of Hexapoda, which is a group of terrestrial arthropods that also includes the insects ( Hopkin, 1997 ; Misof et al., 2014 ). Compared to the insects, springtails lack...

... in the anterior intestine and probably acts to control luminal osmotic pressure while enhancing apical anion exchange; both processes with implications for water absorption. Cytosolic carbonic anhydrase (CAc) activity facilitates CO 2 hydration to fuel apical anion exchange while membrane-associated, luminal CA...

.... Drinking rate decreased substantially at 12 h (32% of control value) and remained suppressed after 3 and 7 days in fresh water (34 and 43%). By contrast, there was a transient increase in the capacity for water absorption measured across isolated intestines in vitro (3.3- and 2.6-fold at 12 h and 3 days...

Our data also suggest that additional attention needs to be paid to the issue of biological fractionation when using...
