- Abstract
We present data on the stomach contents and the gross morphology of the fat body in Agile Frogs (Rana dalmatina) from a pond which is an object of a long-termed monitoring. We also provide information on the diet of one female of Lissotriton vulgaris. All of the specimens were found dead during the mating season, when sudden snowfalls and depression in the temperature covered the ponds with ice and snow layer for several days. The stomach content of the frogs was represented by some chitin rests, shed-skin, and plant material. The fat bodies of the frogs were dramatically reduced in size - an indicator of low level of energetic reserves. We conclude that on the basis of our findings, massive investigations by using stomach flushing methods during the mating season in the Agile Frogs have to be avoided.
