temperature is directly determined by the temperature of its environment (Mellanby 1939). Løkke and van Gestel (1998) stated that the rate of the metabolism is controlled by the environmental temperature for ectotherms. As seen by Wieser‚ cited in Wang and Schreiber (1999)‚ P. scaber’s metabolism increased with higher temperatures.
