The courtship behaviour of the Bosca's newt, Triturus boscai (amphibia: salamandridae)
Languages of publication
The courtship bevaviour of the Bosca's newt (Triturus boscai) is described. In the first phase the male displays in front of the female. Two different movements are performed during display: the Fan adn Flick. Flicks are produced at the end of the display. In the second phase the male desposits spermatophore(s), often without any positive feedback from the female. A conditional male behaviour produced when the female is not receptive, is Flamenco, in which the tail-tip of the male functions as a bait mimic. The adaptive significance of the characteristics of T. boscai's sexual behaviour and the evolution of sexual signals through "sensual exploitation" in the henus Triturus are discussed.
