Abstract: The biology of a Speleomantes ambrosii population inhabiting interstitial habitats was studied during two consecutive years in north-western Italy. Surface activity was highest in late spring and early foll and was positively correlated with monthly rainfall. The population structure was analysed on the basis of polymodal size frequency distributions. S. ambrosii demographic structure was composed of two juvenile size classes and a mixed component in which subadult and reproductive salamanders were present. Males bernme sexually mature when >50 mm and females when >58 mm SVL. Estimated age at first reproduction was 3.5 years for males and 5 years for females. Juvenile growth rates. during the first two years of life, ranged from 10 to 13 mm/yr.
