title: [Changes in erythrocyte count of newts during periods of sexual activity].
abstract: Newts (Triturus cristatus carnifex) raised for the first six months of the year at temperatures not less than 10 degrees C did not undergo hibernation with a drop in the number of their erythrocytes. On the contrary, during their wintertime period of sexual activity and parallel development of secondary sex characters, the red blood cells reached a much higher concentration than was previously assumed to be normal.
