Seasonal variations in liver metabolism of the green frogRana esculenta (L.)

  • R. Schlaghecke
  • V. Blüm


Rana esculenta (L.) kept under natural conditions show almost constant b.wt in the annual cycle. Liver weight, however, has a distinct peak in October/November which is also evident in the liver index. The liver storage materials: glycogen, triglyceride and protein, show 2 distinct maxima (spring, autumn).
