OLFACTORY ATTRACTANTS IN SEX RECOGNITION OF THE CRESTED NEWT. AN ELECTROPHYSIOLOGICAL RESEARCH

Abstract

SUMMARY Electrophysiological methods were used to demonstrate a chemosensitive discriminatory activity of the female crested newt towards the water inhabited by sexually active males. The present research suggests that the abdominal gland, a secondary sex character peculiar to the male, is a possible source of the olfactory sex attractants emitted by males.
