Uneven distribution of biodiversity over the Earth's surface is a consequence of historic, environmental and functional factors. In this paper, spatial patterns of amphibians, reptiles, mammals and birds have been studied in a biogeographical gradient between Pyrenean and Mediterranean environments in Navarra. Also, the relationships between biodiversity, species richness, and biogeographical gradient have been measured with directional semivariograms and GIS. Results show correlations between biogeographical change and spatial patterns of vertebrates: reptiles have the higher values of species richness in the ecotone, while amphibians have an uneven distribution. Mammals and birds show lineal correlations with biogeographical change but in opposite directions.
