Abstract
Seasonal changes in the liver copper content of the common shrew were measured over two years. The copper content increased rapidly in autumn; in one year the levels remained high until the Spring, but the following winter there was a sharp decrease after December. It is suggested that differences in liver copper content are connected with differences in the metabolic steady state caused by differing environmental conditions in the two winters.
