Salt adaptation in Bufo bufo

open access: yesThe Journal of Physiology, 1973
1. The capacity of adaptation of toads (Bufo bufo) to environments of high salinity was studied and the relative importance of skin, kidney and urinary bladder in controlling the balance of water and salt was assessed.2. Toads were kept in NaCl solutions of 20, 50, 110, 150 and 220 m M and studied in their fourth week of adaptation.
