Abstract:
We have investigated behavioral responses of Rana arvalis Nilss. tadpoles to water carrying various water-soluble chemical stimuli: natural lake water; dechlorinated tap water; water in which tadpoles were kept; water with chemical characteristics of the jellylike remains of their own or other clutches after tadpole hatching; boiled nettle, which was used as food for laboratory animals; and water containing toxins of the skin glands of the common toad Bufo bufo L. The preference for natural water over the tap water was revealed, as well as the fact that naive tadpoles were attracted by the “smell” of nettles and tried to avoid toxins.
