Can DNA barcoding accurately discriminate megadiverse Neotropical freshwater fish fauna?
BackgroundThe megadiverse Neotropical freshwater ichthyofauna is the richest in the world with approximately 6,000 recognized species. Interestingly, they are distributed among only 17 orders, andExpand
Phylogenetic relationships within the speciose family Characidae (Teleostei: Ostariophysi: Characiformes) based on multilocus analysis and extensive ingroup sampling
BackgroundWith nearly 1,100 species, the fish family Characidae represents more than half of the species of Characiformes, and is a key component of Neotropical freshwater ecosystems. TheExpand
Karyotype variability in eight species of the subfamilies Loricariinae and Ancistrinae (Teleostei, Siluriformes, Loricariidae)
Abstract Loricariidae is one of the largest fish families of the world, with about 650 species separated into six subfamilies. To date, cytogenetic data on only 56 species of this family areExpand
Deep barcode divergence in Brazilian freshwater fishes: the case of the São Francisco River basin
Background and aims. The application of DNA barcoding as a global standard for fish identification is probing diverse worldwide realms (Nearctic, Australian and the Neotropics) and environments (e.g.Expand
Competition and phylogeny determine community structure in Müllerian co-mimics
Until recently, the study of negative and antagonistic interactions (for example, competition and predation) has dominated our understanding of community structure, maintenance and assembly.Expand
Karyotypic relationships among the tribes of Hypostominae (Siluriformes: Loricariidae) with description of XO sex chromosome system in a Neotropical fish species
The family Loricariidae, with about 683 species, is one the largest fish families in the world. The subfamily Hypostominae was recently reviewed and is now divided in five tribes. With the mainExpand
Extensive chromosomal rearrangements and nuclear DNA content changes in the evolution of the armoured catfishes genus Corydoras (Pisces, Siluriformes, Callichthyidae)
Karyotypes and nuclear DNA content were studied in 11 species of the genus Corydoras from rivers in South America: C. sp. from Caripi river 2n=60, C. cf. simulatus 2n=62, C. simulatus 2n=62, C.Expand
Non-destructive genetic sampling in fish. An improved method for DNA extraction from fish fins and scales.
DNA-based studies have been one of the major interests in conservation biology of endangered species and in population genetics. As species and population genetic assessment requires a source ofExpand
A cytogenetic study of Diplotnystes mesembrinus (Teleostei, Siluriformes, Diplomystidae) with a discussion of chromosome evolution in siluriforms
Abstract The mitotic chromosomes, nucleolus organizer regions (NORs), C-banding patternand nuclear DNA content of Diplomystes mesembrinus were studied. The karyotype, with2n=56 chromosomesExpand
Genetic structure of the migratory catfish Pseudoplatystoma corruscans (Siluriformes: Pimelodidae) suggests homing behaviour
Pseudoplatystoma corruscans is distributed widely in the La Plata Basin in Brazil, where it is a very important species because of its high commercial value and ecological role as a voraciousExpand
