Abstract

The golden spiny mouse is dependent on non shivering thermogenesis (N.S.T.) for thermoregulation at cool ambient temperatures. Mice from the shores of the Dead Sea (Ein-Gedi, EG-mice) lose body heat when exposed to 6 degrees C. Their rate of cooling is linearly correlated to the magnitude of N.S.T. This is true for mice acclimated to 28 degrees C, born in the laboratory or freshly captured. Mice from the high mountains of South Sinai (S-mice) resist cooling under the same conditions and their N.S.T. is about twice that of EG-mice. EG-mice did not acclimate to cold. However thyroxine injections made them cold resistant and their N.S.T. rose to values close to that of S-mice. Light and electronmicroscopy of the thyroids in mice acclimated to 28 degrees C and exposed to 6 degrees C, or injected with TRH suggested intense activity in S-mice and little activity in EG-mice.
