Heart rate, survivorship, oxygen consumption, and metabolic end product accumulations in the intertidal limpets Collisella pelta and Collisella digitalis in relation to desiccation and hypoxia

Creator:

Boese, Bruce Leon

Abstract:

The heart rate, oxygen consumption, survivorship, and 1-lactate accumulation were determined in the intertidal limpets Collisella pelta and Collisella digitalis in relation to laboratory desiccation at 15°C or 30°C. Water loss was computed as a percentage of total initial body water (wet weight - dry weight). Although water was lost...

The histopathological effects of larval trematodes on the hepatopancreas of Oxytrema siliqua (Gould)

Creator:

Porter, Clarence Alan

Abstract:

The histopathological and histochemical effects on the snail Oxytrema siliqua, caused by the larvae of Nanophyetus salmincola, have been studied. The parasite causes damage to the organ by increased pressure, active ingestion of the hepatic tubules, and by the increased burden placed upon the snail in disposing of the waste...
