Further records of Auchenipteridae and Pimelodidae from Suriname (Pisces: Nematognathi)

, 1985
Collections of freshwater-fishes, made in recent years in Suriname, have yielded four species of Auchenipteridae and ten species of Pimelodidae. Of the latter, two species, viz., Phractocephalus hemioliopterus and Pimelodus heteropleurus, are additions ...

High trophic niche overlap between sympatric peacock basses (Cichliformes: Cichlidae: Cichla): Concordant findings from three dietary analysis methods. [PDF]

J Fish Biol
Abstract Dietary analysis has contributed to our understanding of animal niches, interspecific interactions, community structure and the flow of matter and energy in food webs. We employed three methods of dietary analysis to estimate trophic niche overlap between two peacock bass species, Cichla cataractae and Cichla ocellaris, across sympatric ...

Hybridization, Maternal Inheritance, and Evolutionary Time of Divergence of Endangered Species of <i>Hypancistrus</i> (Siluriformes: Loricariidae) in the Xingu River. [PDF]

Ecol Evol
We uncover recent hybridization dynamics among three endemic Hypancistrus species from the Xingu River, including the critically endangered H. zebra. Mitogenomic analyses reveal unidirectional maternal inheritance and recent evolutionary radiation (< 0.5 Ma), explaining their retained reproductive compatibility.

Morphological and Histometric Alterations in Gonadal and Neural Tissues of Native and Non-Native Fishes From the Lower Doce River Basin in Southeastern Brazil. [PDF]

Anat Histol Embryol
ABSTRACT The ichthyofauna of the lower Doce River basin has been exposed to multiple anthropogenic stressors. Among these, the collapse of the Fundão mining tailings dam in Mariana, Minas Gerais, Brazil, in 2015 resulted in massive fish mortality and widespread contamination of aquatic environments.

Molecular phylogeny reveals a new species of ghost electric knifefish Porotergus Ellis 1912 (Gymnotiformes: Apteronotidae), from the Amazon basin. [PDF]

J Fish Biol
Abstract A new species of ghost electric knifefish, Porotergus sambaibensis sp. nov., is described from the Javaés River, a tributary of the Araguaia River in Brazil. The new species was assigned to the genus Porotergus as the closest relative to Porotergus gimbeli through maximum likelihood reconstruction of a concatenated multilocus dataset ...

Integrative morphometric and molecular analyses reveal possible genetic contamination of silver catfish populations of the genus Rhamdia in Neotropical River basins. [PDF]

J Fish Biol
Abstract Rhamdia quelen, Rhamdia branneri and Rhamdia voulezi are morphologically similar species that, until recently, were considered synonymous. Although R. quelen has wide distribution in the Neotropical region, R. branneri and R. voulezi are sympatric and endemic species of the Iguaçu River basin.

Is there hidden genetic variability in the species of <i>Steindachneridion</i> Garavello, 2005 (Siluriformes: Pimelodidae)? [PDF]

PeerJ
Background The genus Steindachneridion, which includes large-sized freshwater pimelodid species, is endemic to the southeastern coastal drainages of South America, specifically the Paraná River and Uruguay River basins.

Transferability of heterologous microsatellite primers in Leiarius marmoratus

Semina: Ciências Agrárias, 2020
The Amazonian Jundiá (Leiarius marmoratus) (Siluliformes: Pimelodidae) is a species of catfish with social and economic importance in some South American countries such as Brazil and Colombia. Genetic evaluation of this species is limited due to the lack

Redescriptions of two little-known pimelodid catfishes from the São Francisco River basin, Brazil: Duopalatinus emarginatus and Bagropsis reinhardti (Teleostei: Siluriformes) [PDF]

Neotropical Ichthyology
The São Francisco River basin in eastern Brazil harbors a highly endemic ichthyofauna, including the poorly known pimelodid catfishes Duopalatinus emarginatus and Bagropsis reinhardti.
