| Abstract |
and Anadara granosa experience hypoxic conditions and can regulate their O2 consumption at reduced O2 tension in water of full salinity. (2) These 2 species, and Mytilus edulis, can also regulate O2 consumption at reduced O tension in diluted sea water. Their capacity to regulate is reduced under these conditions, although only in Anadara is this reduction very marked. (3) At reduced salinity, O2 consumption by Mytilis is inhibited at first, but recovers within 48 hour. The ability to regulate O2 uptake at reduced oxygen tension is not lost during the acclimation period. (4) at 23.5% S perfusion index increases with reduced PO2, but at 16.3% S perfusion index does not change as PO2 is reduced to 60 mm Hg. |
