[A pullulation cycle with violent crash in a tropical lizard].
According to a succession of samples taken at Ihotry, Madagascar, Lygodactylus tuberifer, a very rare gecko in the biotope sampled for Lygodactylus verticillatus in 1965, invaded the latter's habitat until its population reached, in the sampled biotope and using the L. verticillatus population as a gauge, an almost 700-fold increase by the end of 1972. Population growth then stopped abruptly, and a steep crash brought L. tuberifer down to 31 times less individuals within six months, whereupon sampling was discontinued.
