Abstract

Catalonia is a rich area in Biodiversity, its orography and geographic position produce a rich variability climatic area. In this paper, we determine environmental factors (climatic, geographic and geologic) that influence the regional corotypes of vascular plants. We use distance based redundancy analysis (dbRDA). Results show that environmental factors explain 83,77 % of the variance of the species distribution in corotypes, and the two first canonical axis explain 70,13 %. The first axis is related with altitude and the second axis with the soil reaction (basic/acid) and the coast distance (oceanity/continentality). The correlation of species distribution and environmental variables allow to study the behavior of the species to changes in environmental conditions
