Thermal Acclimation In The Resting Metabolism Of The Nocturnal Gecko, Hemidactylus Flaviviridis

Abstract

Hemidactylus flaviviridis was acclimated to two temperature regimes (20 and 30°C). The resting metabolic rates (ml g1 h"1) were determined at 20, 25,30 and 35°C, using constant pressure manometric respirometers. The 20°C- acclimated geckos had significantly lower metaobolic rates than the 30°C- acclimated geckos only at 20°C. Oxygen consumption rates increased as temperature increased with high thermal sensitivity (Q10= 5.6) Between 20 and 25°C for the cold-acclimated group, and low thermal sensitivity (Q10 =1.1) between 20 and 25°C for the warm-acclimated group.
