|
Preliminary study of the breathing responses at various temperatures in Testudo hermanni hermanni (Chelonia, Testudinidae). There are two kinds of breathing in Hermann's Tortoise, thoraco-abdominal and bucco-pharyngeal. Comparing pulmonary breaths (VEpul) at 10°C (818 ±479 microliters min-1), 25°C (1963 ±1014 microliters min-1) and 30°C (1436 ± 188 microliters min-1), the thermal preferendum was between 25 and 30°C. Moreover, total volumes of air inhaled by subadults increased significantly between 10 and 30°C. Total volume inhaled by subadults and breathing frequency of juvenile Testudo hermanni hermanni seem to be the mosl important factors in breath control when temperature is outside the lortoise's thermal comfort zone. Breath pauses in juvenile tortoises are greater than in subadults at fow temperatures.
