.... Cooling during entry into hibernation bouts followed a Newtonian cooling curve, and conductances calculated from cooling curves were identical to those observed in cold exposed euthermic echidnas. Comparison with a reference soil temperature demonstrated that echidnas showed behavioural thermoregulation...

... with a different defect in an identified ion conductance, to show that these two stimuli open different ion channels, and the behaviors that occur upon application of stimulus (on-response) and removal of stimulus(off-response) have different roles in attraction to these two stimuli. The most important parameters...

... loss, and calculated wet thermal conductance, for bats exposed to air temperatures ranging from 0 to 40°C for periods of 2-5 h. Pregnant females maintained normothermic body temperatures (35.7±0.7°C; mean ± s.e.m. )independent of air temperature. In contrast, males became torpid during the majority (68...

..., evaporative cooling and thermal conductance of 1- to 3- week-old downy scolopacid chicks (least sandpiper Calidris minutilla; short-billed dowitcher Limnodromus griseus ; whimbrel Numenius phaeopus ). Body mass ranged from 9 to 109 g. To accurately measure the interacting effects of air temperature and wind...

... at a conductance ( G te ) of 40±2 mS cm –2 . The net influxes of Na + and Cl – were 8.3±2.6 and 18.2±2.7 μmol cm –2 h –1 , respectively. External amiloride (100 μmol l –1 ) reduced G te to approximately 50 % of the original value at unchanged I sc ; Cl – fluxes remained unaffected, whereas Na + fluxes were...

... and oxygen conductance increased in response to hypoxia. We investigated this possibility in two salamander species, Ambystoma annulatum and Ambystoma talpoideum . The effective surface area of egg capsules increased in response to hypoxia, which increased the conductance for oxygen and enhanced oxygen...
