Resultados preliminares de la caracterización del esturión de la península Ibérica mediante el análisis del gen citocromo b
Historically, the Atlantic sturgeon Acipenser sturio L., 1758 was considered the only sturgeon species that inhabited rivers of the Iberian Peninsula. Nevertheless, in a recent paper, Garrido- Ramos et al. (1997) identified specimen EBD 8174 (museum collection of the Doñana Biological Station, Spain...
