Extensive karyotype variability of African fish genus Nothobranchius (Cyprinodontiformes) [PDF]
Comparative Cytogenetics, 2018 Karyotypes of 65 species of the genus Nothobranchius Peters, 1868 were reviewed and of those 35 examined first time. The results of present study have shown that fishes of the genus Nothobranchius possessed highly diverse karyotypes.

Genomic Signatures Associated with Transitions to Viviparity in Cyprinodontiformes. [PDF]
Mol Biol Evol, 2023 AbstractThe transition from oviparity to viviparity has occurred independently over 150 times across vertebrates, presenting one of the most compelling cases of phenotypic convergence. However, whether the repeated, independent evolution of viviparity is driven by redeployment of similar genetic mechanisms and whether these leave a common signature in ...

Male Copulatory Structures in Reproductively Functional Female Live-Bearing Fish <i>Pseudopoecilia fria</i>. [PDF]
Ecol EvolWe recently discovered a population of the live‐bearing fish Pseudopoecilia fria (Cyprinodontiformes: Poeciliidae), in which females were found to possess gonopodia, reproductive organs normally exclusive to male fish that are used in the transfer of sperm in mating.

Description of Encephalon Morphology of Nile Tilapia Oreochromis niloticus (Linnaeus, 1758) (Perciformes: Cichlidae) From Brazil. [PDF]
Anat Histol EmbryolABSTRACT The Nile tilapia (Oreochromis niloticus) is a cichlid species native to Africa and is widely farmed in tropical and subtropical regions around the world, making it one of the most commercially important aquaculture species. Despite its significance, there is still a lack of detailed anatomical descriptions of its brain.

Linking rivers, mixing faunas: How artificial connectivity between the Middle and Upper Paraná River basins shapes fish diversity in a tributary of the Itaipu Reservoir, Brazil. [PDF]
J Fish BiolAbstract This work aimed to investigate the distribution and occurrence of fish species along the São Francisco Falso Braço Norte (SFFBN) River basin, a tributary of the Middle Paraná River basin now artificially connected to the Upper Paraná ecoregion, to evaluate how such connectivity may affect the biogeographic distribution and regional composition

On the measurement of ecological novelty: scale-eating pupfish are separated by 168 my from other scale-eating fishes. [PDF]
, 2013 The colonization of new adaptive zones is widely recognized as one of the hallmarks of adaptive radiation. However, the adoption of novel resources during this process is rarely distinguished from phenotypic change because morphology is a common proxy ...

The complete mitochondrial genome of the Variable Platyfish Xiphophorus variatus
Mitochondrial DNA. Part B. Resources, 2021 We present the complete mitochondrial genome sequence of the Variable Platyfish, Xiphophorus variatus (Meek 1904) (Cyprinodontiformes: Poeciliidae). The genome consists of 16,624 bp which encodes 13 protein-coding genes, 22 transfer RNAs, 2 ribosomal ...
