  • Title: [Behavioral reactions of Bufo bufo L. tadpoles to chemical excretion of adult toads and changes during larval development].
    Author: Kiseleva EI.
    Journal: Zh Obshch Biol; 2001; 62(5):430-6. PubMed ID: 11605553.
    Abstract:
    The reactions of toad (Bufo bufo L.) tadpoles to chemical excretes of adults were studied. In double-choice test aquarium tadpoles demonstrated avoidance reactions (swimming away from the place of stimulus delivering, reduction time of spent in stimulus part of aquarium and reduction of movement activity). Efficiency of stimulus reduced when its concentration decreased. The thresholds of tadpoles sensitivity estimated according to the reduction of time spent in stimulus part of aquarium decreased in onthogeny: they were near 500 x 10(-5) g hour/l at 36-39 developmental stages and 500 x 10(-4) g.hour/l at 40-41 stages.
