Effects of photoperiod on sodium flux in Corbicula fluminea (Mollusca:Bivalvia)

Ion Transport in the Freshwater Zebra Mussel, Dreissena polymorpha

“…The variability in ion transport and the magnitude of ion losses in some Dreissena polymorpha acclimated to pondwater exceed the range found in other freshwater bivalves. Freshwater mussels are normally nocturnally active and tend to gain salts at night and lose ions during the day (Graves and Dietz, 1 980;McCorkle-Shirley, 1982). Perhaps Dreissena has more pronounced diurnal rhythms of ion transport.…”

Osmoregulation and Excretion

“…The uptake of ions in some freshwater bivalves follows a diurnal rhythm (638, 1200). These observations suggest that the nervous system regulates the function of the uptake mechanisms.…”

Ecology of an Invasive Pest Bivalve, Corbicula

“…Salt depletion also significantly increases the total inward and outward flux of Na+ and the rates of Na"^ exchange diffusion (McCorkle and Dietz, 1980). C. fluminea also shows a diumal oscillation in Na^ uptake, Na"^ rates being greatest during dark periods and suppressed by light (McCorkle-Shirley, 1982). Because only H"^ is exchanged for Na"^ in pond water-acclimated individuals, Na + /NH4+ exchange diffusion appears to be an accessory mechanism of Na"*" uptake in salt-depleted individuals (McCorkle and Dietz, 1980).…”
