Abstract
We analyze the distribution patterns of 15 species of amphibians in the province of Alava. For this objective, a presence/absence methodology was used with the observations mapped in UTM 5 x 5 km grids, and the relationship with different variables such as climatic, orographic and landscape were treated in a GIS (Geographical Information System). The statistical analysis was performed using a canonical correspondence analysis (CANOCO). The climatic variable,s especially rainfall and maximum temperature were found the most influential. The amphibian species were clustered in three different distribution pattern groups: montane and hygrophilic species, mediterranean and submediterranean species, and widely distributed species. Rana dalmatina did not fit well with any of these groups.
