Gill tissue masses and oxygen consumption of Gobionotothen gibberifrons, Notothenia coriiceps and Zoarces viviparus ...
Mechanisms responsive to hypercapnia (elevated CO2 concentrations) and shaping branchial energy turnover were investigated in isolated perfused gills of two Antarctic Notothenioids (Gobionotothen gibberifrons, Notothenia coriiceps). Branchial oxygen consumption was measured under normo- versus hyper...
