El límite sur de la región mediterránea de Baja California, con base en sus tetrápodos endémicos

[摘要] To determine the southern limit of the mediterranean region in Baja California I analized the distribution of most tetrapods that breed in the area. I concluded that the limit of this community coincides with Arroyo del Rosario (aprox. 30º Lat. N), although mediterranean taxa begin to dissapear since Arroyo de San Telmo (Aprox. 30°57' Lat. N). Some desert species come in from the south and reach as far north as Ensenada (31°52' Lat. N). So, this area is largely a transitional zone. Of all tetrapods that breed in the area, 4 species and 54 subspecies are endemic to the American mediterraneum (Baja California and California, U.S.A.), and several of these are insular.
