The Amazon is probably the most diverse realm on Earth, and is considered to be the primary source of diversity and a center of dispersal for Neotropical terrestrial organisms. Yet, the assumption that the Amazon basin is a primordial place of fish species origination and dispersal into other drainages still need to be tested. We addressed this iss...

With an estimate of around 9,000 species, the Neotropical region hosts the greatest diversity of freshwater fishes of the world. Genetic surveys have the potential to unravel isolated and unique lineages and may result in the identification of undescribed species, accelerating the cataloguing of extant biodiversity. In this paper, molecular diversi...

El objetivo de este Proyecto es la discriminación, descripción y caracterización biológica de poblaciones y/o unidades evolutivamente significativas de peces de Argentina. Nuestro modelo de estudio incluye un grupo de peces de alto valor socio-económico: el pejerrey escardón (Odontesthes argentinensis), una nueva especie de tararira recientemente descripta por los investigadores del presente proyecto (Hoplias argentinensis) y la lisa de presencia permanente para Argentina (Mugil liza). La elección de estas especies no azarosa dado que las mismas, además de estar sujetas a la explotación de pesca recreativa y comercial, representan en todos los casos situaciones de alta incertidumbre respecto a su identidad poblacional en diferentes regiones geográficas. Para abordar esta temática se utilizará un eje integrador aunando aproximaciones taxonómicas y biológicas (metodologías moleculares, morfogeométricas, morfológicas, reproductivas, bioquímico-fisiológicas y parasitológicas) que contribuyan a discriminar, describir y caracterizar diferentes poblaciones o UES en estas especies.
