Abstract:Summary In connection with the circannual testicular rhythmRana esculenta does not seem to be a strictly photoperiodic species. In fact testicular growth can be induced (at a favourable temperature) with a daily 2-h light pulse as well as with a daily 12-h light pulse.Work done under the CNR-finalized project lsquoBiologia della Riproduzionersquo.
