Changes in body fluids of the cocooning fossorial frog Cyclorana australis in a seasonally dry environment

We investigated changes in the lymph (equivalent to plasma) and urine of the cocooning frog Cyclorana australis during the dry season in monsoonal northern Australia. Frogs in moist soil for two days were fully hydrated (lymph 220 mOsm kg − 1 , urine 49 mOsm kg − 1 ). From five weeks onwards the soi...
