The reproductive biology of Salamandrina terdigitata (Caudata, Salamandridae)
We studied the reproductive biology of the spectacled salamander, Salamandrina terdigidata, in Central Italy by daily sampling over three breeding seasons. Reproduction takes place annually, between February and May. Clutch size varies (1–65), and are usually placed by females on the underside of stones. The total number of eggs deposited varies yearly and is positively related to the period of preceding rainfall. Large females start breeding earlier and show stronger oviposition site fidelity than small ones. For oviposition females choose the portions of the stream that have the highest density of stones. The speed at which embryos develop increased over time, presumably under the influence of rising water temperature. Hatching success is negatively affected by aquatic drift, desiccation, predation by Trichoptera larvae and the absence of hiding sites.
