... Anuran amphibians are known to learn chemical stimuli in embryonic and larval development. Data on "kin recognition" and data on learning of native pond odor are considered as parts of complex chemical imprinting typical for other groups of vertebrates. ... Keywords: amphibians, larval development, chemical imprinting, "kin recognition," native pond odor, sensitive periods. ... We assume that "kin recognition" and learning of native pond odor should be viewed as a complex chemical imprinting. ...
