Genetic structure of the ornamental tetra fish species Piabucus melanostomus Holmberg, 1891 (CHARACIDAE, IGUANODECTINAE) in the Brazilian Pantanal wetlands inferred by mitochondrial DNA sequences

Abstract: Genetic structure of the ornamental tetra fish species Piabucus melanostomus Holmberg, 1891 (CHARACIDAE, IGUANODECTINAE) in the Brazilian Pantanal wetlands inferred by mitochondrial DNA sequences. Biota Neotrop. 13(1): http://www.biotaneotropica.org.br/v13n1/en/ abstract?article+bn00413012013 Abstract:The subfamily Iguanodectinae comprises a group of small Neotropical fishes composed by two genera and 11 nominal species widely distributed in the Atlantic drainages of South America. Piabucus is the only genus o… Show more

“…Molecular techniques, including sequences of mitochondrial DNA (mtDNA) have proven especially effective for the evaluation of the genetic diversity of a wide range of fish taxa, and the Control Region has been used for the analysis of the population structure of a large number of species (Santos et al, 2004;Calcagnotto et al, 2005;Fraga et al, 2007;Cheng et al, 2012;Borba et al, 2013).…”

“…The effect of local environmental changes related to flood pulses within the Pantanal is reflected in the species composition of several taxonomic groups of various forms (Zeilhofer & Schessl 1999, Oliveira & Calheiros 2000, Alho & Silva 2012, Catian et al 2018, as well as in the genetic aspects of some species (Borba et al 2013). Highly dispersed species can compensate for these environmental differences and maintain interlocking populations (Faria et al 2008).…”

“…Another factor that could explain these genetic characteristics is the flood pulse in the Paraguay River region [18,19]. This event influences biodiversity in the region [20] (Calheiros & Ferreira 1997) and was already shown to influence the genetic structure of fish species such as Piabucus melanostomus (Holmberg, 1891) [21].…”
