Temperature regulation in insects
Web20 Feb 2012 · Thermoregulation is the control of body temperatures. Animals are classified into two main thermoregulating types: endothermic and ectothermic. Endotherms (endo- means "within" and -therm means "heat"), such as humans, other mammals, and birds, create their own heat. This enables many of them to live in a broad range of environments, … Web15 Feb 2004 · We assess thermoregulatory ability using two measures: (1) the relationship between thoracic temperature during flight and ambient temperature and (2) the relationship between thoracic temperature during flight and the effective (operative) temperature of a dead beetle in the flight position (index of thermoregulatory …
