...P. Venditti; L. Di Stefano; S. Di Meo Summary Exposure of homeothermic animals to low environmental temperature is associated with oxidative stress in several body tissues. Because cold exposure induces a condition of functional hyperthyroidism, the observation that tissue oxidative stress also...

.... The present study aimed to examine whether Brandt's voles Lasiopodomys brandtii could adjust energy intake and thermogenesis to accommodate simultaneous lactation and cold exposure. The voles were placed into two temperature treatments: warm(23±1°C) and cold (5±1°C). Animals at each temperature treatment were...

... exchange efficiency during cold exposure was also shown by the composition of the gas in the interclavicular air sac. P O2 decreased from 11.95 kPa at 20°C to 10.24kPa at 5°C, while the corresponding increase in P CO2 was from 6.61 to 7.50 kPa. Oxygen extraction, calculated from V O2 , Vi and O 2 content...
