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 ...

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.

Karyosystematics of an Endemic tooth-carp, Aphanius shirini (Teleostei: cyprinodontidae) from Iran [PDF]
Journal of Cell and Molecular Research, 2017 The karyological and cytological characteristics of an endemic cyprinodont fish of Iran, Aphanius shirini have been investigated for the first time by examining metaphase chromosomes spreads obtained from gill epithelial and kidney cells.

Fish, Sorocaba river sub-basin, state of São Paulo, Brazil. [PDF]
Check List, 2007 In this paper we present a list of the fish fauna of Sorocaba river sub-basin. Fish were caught with gillnets,sieves and puçás, a sort of funnel net. We listed 71 species, distributed in 7 orders, 22 families and 50 genera.Characiformes are represented ...

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 ...

Patterns and drivers of Nothobranchius killifish diversity in lowland Tanzania
Ecology and Evolution, 2022 Temporary pools are seasonal wetland habitats with specifically adapted biota, including annual Nothobranchius killifishes that survive habitat desiccation as diapausing eggs encased in dry sediment.
