Abstract: | The influence of desiccation and temperature on the respiratory metabolism of P. viridis have been investigated. There was a significant (p < 0.05) downfall in the respiratory rates as the period of desiccation increased, but for after 18 hours where it was enhanced significantly. The respiration augmented significantly (p < 0.03) when the temperature of the medium increased. Q10 was significantly high at 32–28°C and was low between 35 and 32°C and 20–10°C Functional significance of these changes to the leeches in combating environmental hazards is briefly discussed. |
