Distribution, ecology and conservation of the parsley frog (Pelodytes punctatus) in Italy (Amphibia, Pelodytidae)

Abstract

In Italy, the parsley frog (Pelodytes punctatus) reaches the eastern limit of its distribution range along the Mediterranean coast in Liguria and in southern Piedmont. The status of the Italian populations was analysed on the basis of a complete survey of known breeding sites. Since 1993, the reproduction of P. punctatus has been observed in only 15 sites, several of which were discovered during the monitoring project. Spawning sites were mainly small temporary pools, small streams and artificial tanks in Mediterranean habitats. The number of breeding females was estimated indirectly counting egg strings both in spring and autumn, from 2000 to 2002. Populations appeared isolated and made up of an extremely low number of reproductive females (range 2-19, mean 9). In Italy. P. punctatus populations show a fragmented distribution and appear threatened mainly by the drying up of pools or habitat destruction. For each reproductive site, the conservation status was evaluated, and a general conservation strategy...
