Studio della diversità di anfibi nelle Oasi WWF italiane nel contesto dei futuri scenari di cambiamento climatico e di alterazione degli habitat

Faunistic knowledge is a fundamental requirement for conservation biology . Main aim of this work is to study the WWF Oases amphibian richness, and to individuate areas which deserve of special conservation attention for those species . We further related our analysis of Oases conservation value for amphibians to the estimate of spatial parameters which describe the human impact in the considered protected areas and predicted changes in climatic parameters under the CCM3 climatic model by the end of this century . Our results show that WWF Oases are generally characterized by an high amphibian richness, and on the basis of our prioritization, the most important areas protected by WWF for amphibian conservation are Guardiaregia-Campochiaro (Molise region), Valle Averto (Veneto region), and San Felice (Tuscany) . Those Oases have also low values of human impact on ecosystems . Concerning the estimates of future climatic variation in the Oases, our results clearly claim a grave danger for the considered areas . In fact, over 90% of the Oases are predicted to suffer for a temperature increase of the mean annual value and a general precipitation decrease.
