摘要：The aim of the BIOFRAG project is to understand how environmental factors explain herpetological biodiversity in the Mediterranean Basin, with a focus on to identify management options by anticipating or by maintaining the biodiversity. Knowing which biotic and/or a-biotic factors influence biodiversity in a certain region monitoring their change (for instance habitat fragmentation), allows predictions of change in biodiversity of a certain ecosystem and warning on extinction or endangerment of certain species. The project includes biodiversity aspects of both amphibians and reptiles and its relation with environmental parameters. The project deals with total biodiversity across a landscape. At this stage, several pilot-study areas are operational (in Italy, Portugal, Spain and Greece). In the coming years other pilot area's will start in the Mediterranean to cover all relevant ecotopes. A database is under development covering about all herpetological species (amphibians and reptiles) of the Mediterranean Basin. Data on species distribution patterns, recorded at different scales and in different formats, i.e. polygons, grid, point data and coordinates records, and data related to species habitat requirements/preferences (e.g., vegetation, soil characteristics, geology, drainage, water-bodies, altitude, slope, exposure, temperature, rainfall, radiation, evapo-transpiration, etc.) are all included.Results of some studies using the above mentioned data base indicate the relative significance of various environmental parameters when analyzing the distribution of specific herpetofauna species at different scales, e.g. local, regional and continental. They proofed the usefulness of very specific RS products and of statistical GIS techniques
