Abstract     
Testudinidae Testudo hermanni To sum up, it is hardly feasible to overestimate the influence of temperature on reproductive cycle and migration of Italian (and European) amphibians, especially newts, and reptiles. Global Climatic Changes - including high levels of incident solar radiation- in unison with habitat alterations are responsible for the biodiversity crisis of Italian (and European) populations of Amphibia. The following steps attract reader’s attention on the landmarks up to now focalized. Ecological modelling approaches to the change of habitat suitability is a powerful tool in the study of short and long-term conservation of endangered species. An up-to-date knowledge of the present distribution of a given species in a certain territory and climatic scenario is required. Such examples are numerous in the various countries; for instance, in Italy, the databank is linked to the so-called CKmap’ initiative which is supported financially by the Italian Ministry for the Environment, Land and Sea Protection (Blasi et al., 2007). Environmental factors related to species occurrence and present suitable areas, clearly represent the rudiments of this approach. Further on, both land cover and morphology together with human impact layers are considered as covariates to climatic predictors. Different methods for modelling habitat suitability and binary predictions (presence / absence of the species) are performed. Models may be applied for some time slices, present and future - at selected intervals, e.g. 2030, 2050, 2070. Results indicate which squares of the CKmap loose completely their suitability within a certain period. Present conditions with currently known distribution and different (hypothetical) climatic scenarios and environmental changes may be compared. Existing controversies in the field of climatic (and related) phenomena are pointed out. The efficiency of predictions is influenced by many factors; the simplistic assumption that some factors remain unchanged drives to under / over estimation of the persistence probability of the species under the spotlight. A dramatic perspective is the complete extinction from the Central Mediterranean Ecoregion of H. hippocrepis during the next decades; immediate actions for habitat conservation should be organized by the pertinent authorities (Corti et al., 2000). However, the near future will reserve to mankind enormous challenges in the light of supporting and preserving both geodiversity and biodiversity of the Mediterranean Ecoregion.
