..., has an established role in potassium and acid–base regulation in mammals and is well known for its role in gastric acidification. However, the role of HKA in extra-gastric organs such as the gill and kidney is less clear, especially in fishes. In the present study in Nile tilapia, Oreochromis...

... regulation among fish by measuring pH i regulation in 10 different fish species that are broadly phylogenetically separated, spanning six orders, eight families and 10 genera. Contrary to previous views, we show that preferential pH i regulation is the most common strategy for acid–base regulation within...

... and acid–base regulation are at least partly accomplished by the branchiae in E. complanata . High branchial mRNA expression levels of NKA, HAT, CA-2 and a Rh-protein, all genes known to be involved in ammonia excretion and acid–base regulation ( Larsen et al., 2014 ), as well as the observed...

... regulation has been identified in several adult fish species and an aquatic amphibian, but never in adult amniotes. Recently, common snapping turtles were observed to preferentially regulate pH i during development; the pattern of acid–base regulation in these species shifts from preferential pH i regulation...
