Abstract: | The effect of oxygen tension, pH and salt concentrations on the respiratory metabolism of the freshwater leech, Poecilobdella viridis has been studied. The respiratory rate increased significantly (p < 0.05) with progressive elevation of the oxygen tension of the medium and decreased significantly (p < 0.05) in both acidic and alkaline media. The respiratory rate was enhanced significantly (p < 0.05) as the salt concentration of the medium increased. Functional significance of these trends to the leech in counteracting the environmental eddies is briefly discussed. |
