Un problema interesante de biogeografía : La distribución de los Gammarus en el norte de España

Abstract

Durante una dilatada época la finalidad principal de la geografía botánica y zoológica consistió en distinguir “regiones”, los límites de las cuales coincidían con los de las áreas de dispersión de grupos más o menos numerosos de especies, que se consideraban como “características” de la región en cuestión. Más adelante se mejoró esta manera de trabajar tratando de buscar una relación entre la distribución de las especies y la repartición de los, ambientes de diferentes características en la superficie de la tierra, completando este punto de vista con el estudio del origen de las faunas y floras, fundamentado en la paleontología. [...] Gammarus (Rivulogammarus) pulex, Gammarus (Homoeogammarus ) simoni, Gammarus (Echinogammarus) pungens, Gammarus (Echinogammarus) Berilloni [...]
