Rates of energy and phosphorus metabolism in Littorina snails (gastropoda)

Rates of energy and phosphorus metabolism in Littorina snails (gastropoda) Energy metabolism and phosphorus excretion were studied in Littorina littorea and L. saxatilis snails from the White Sea. Some elemental components of the body were determined quantitatively, and the rates of oxygen consumption and phosphorus excretion were estimated. All parameters were calculated relative to dry body weight (mg). Daily expenditures for energy metabolism in Littorina spp. averaged 3.6 ± 1.1%, and those for phosphorus metabolism were approximately four times lower (about 1%), with the total phosphorus content averaging 0.8% dry body weight.

Abstract

Energy metabolism and phosphorus excretion were studied in Littorina littorea and L. saxatilis snails from the White Sea. Some elemental components of the body were determined quantitatively, and the rates of oxygen consumption and phosphorus excretion were estimated. All parameters were calculated relative to dry body weight (mg). Daily expenditures for energy metabolism in Littorina spp. averaged 3.6 ± 1.1%, and those for phosphorus metabolism were approximately four times lower (about 1%), with the total phosphorus content averaging 0.8% dry body weight. The atomic ratio of consumed oxygen to excreted phosphorus for both species averaged O: P = 1164 ± 140.
