Distribución de los peces continentales de España asociada a las características físicas, metereológicas e hidrológicas de las cuencas hidrográficas

Abstract

Spatial  distribution  of  the  mainly  continental  fishes  of  Spain  and  its  relation  by  such  variables  as:  altitude,  rivers  orders,  slope,  rainfalls, average minimal and maximum temperatures, on winter and summer respectively, was analyzed. The hydrographical basins of the: North, Duero, Tajo, Ebro, Guadiana, Guadalquivir, Júcar, Segura, South and Internal Catalonia were considered. The variables were analyzed under
a spatial approach, using a Geographical Information System (GIS). The relationships of the variables mentioned before, both quantitative and qualitative, were determined applying a Multiple Correspondences Analysis
