Un cas de néoténie dans un bâtiment désaffecté, chez le Triton alpestre, Triturus alpestris apuanus (Salamandridae)

A population of Triturus alpestris apuanus of the Apuane Alps (Tuscany , Italy) was studied during July 1994. The particularity of this population is that it breeds in an artificial site, in the dark and under cover, in a deserted building. Moreover some neotenic newts were discovered. The recent colonization and the instability of this biotope indicate a form of labile neoteny, appearing and disappearing spontaneously.
