Abstract

The role of the hypothalamo-hypophyseal neurosecretory system (HHNS) in adaptation to various environments in mammals has not been thoroughly studied. Ecological investigations are mainly concerned with the HHNS of desert-dwelling rodents (HOWE and JEWELL, 1959; KHALIL and TAWFIC, 1963; CASTEL and ABRAHAM, 1969; HATTON et al., 1972). There appear to be no publications on the HHNS in animals living at high altitudes.
