Projections of current and future (2050) distributions of most European amphibian and reptile species are now available online. You can download the data at:

http://www.biochange-lab.eu/resources/data

Data are stored in standard text files with 10’ grid cells in lines and species presence and absence (according to the models) in columns. We provide ensembles of projections that enable assessments of uncertainty.

The parameters that vary are:

• Socio-economic scenarios (A1Fi, A2, B1, B2)
• General Circulation Model (Hadcm3, CSIRO2)
• Bioclimatic model (artificial neural networks, classification tree analysis, generalized additive models, and generalized linear models)
• Cut off rules to convert probabilities into presence absence data (Kappa statistic, AUC of ROC)
  

Details on methods and general patterns in the data are provided by:
