Polygynandry and high genetic diversity supported by kinship and population genetics from neotropical catfish ichthyoplankton

Knowledge about reproductive biology is critical for understanding species ecology and evolution, hence their conservation. However, such information remains elusive for many species due to the difficulty of observing mating in nature. Herein, we coupled population and sociogenetic analysis to asses...

Description
Summary:Knowledge about reproductive biology is critical for understanding species ecology and evolution, hence their conservation. However, such information remains elusive for many species due to the difficulty of observing mating in nature. Herein, we coupled population and sociogenetic analysis to assess the reproductive biology of an important South American catfish, the “painted catfish” Pimelodus maculatus. We analysed the genetic diversity and kinship patterns of three wild ichthyoplankton samples identified by DNA barcoding and screened with microsatellite loci. We found the same trend in the three samples analysed: a high number unrelated larvae (r
