air-breathing fish
- Effects of temperature on acid–base regulation, gill ventilation and air breathing in the clown knifefish, Chitala ornata
Summary: Partitioning of gas exchange in an air-breathing teleost is partially regulated by acid–base status, and respiratory control of pH is more likely with increasing temperature.
- Oxygenation properties of hemoglobin and the evolutionary origins of isoform multiplicity in an amphibious air-breathing fish, the blue-spotted mudskipper (Boleophthalmus pectinirostris)
Summary: The blue-spotted mudskipper routinely switches between aquatic and aerial respiration. This respiratory versatility is associated with properties of hemoglobin–oxygen transport that are similar to those found in hypoxia-adapted water-breathing fishes.
- Renal acid excretion contributes to acid–base regulation during hypercapnia in air-exposed swamp eel (Monopterus albus)
Summary: The swamp eel – an obligate air-breathing fish from South East Asia – can completely restore extracellular pH within days of exposure to hypercapnia and the kidneys play an important role in this response.
- Ammonia exposure affects the mRNA and protein expression levels of certain Rhesus glycoproteins in the gills of climbing perch
Summary: Active ammonia excretion in the gills of the climbing perch, Anabas testudineus, may involve apical Rhag and basolateral Rhcg2 expressed in ammonia-inducible Na+/K+-ATPase α1c-immunoreactive ionocytes.
