Correction to: Mating and aggressive behaviour of Brachyrhaphis olomina (Cyprinodontiformes: Poeciliidae) [PDF]

open access: hybridJournal of Ethology, 2018
Abstract Despite the increasing interest in the use of intromittent male genitalia and coercive mating behaviour in poeciliids, detailed studies of the mating behaviour of most species in this family are lacking. We describe here the mating and aggressive behaviours of Brachyrhaphis olomina, and correlate them with the condition of the female’

Extensive karyotype variability of African fish genus Nothobranchius (Cyprinodontiformes) [PDF]

open access: yesComparative 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.

The complete mitochondrial genome of Poropanchax normani and phylogenetic studies of Cyprinodontidaes

open access: yesMitochondrial DNA. Part B. Resources, 2021
The complete mitochondrial genome of the Cyprinodontiformes fish Poropanchax normani was studied in this study. The size of the entire mitochondrial genome was 16,878 bp, and the total length of the encoding sequence was 11,435 bp, accounting for 67.75%,

Protogynous functional hermaphroditism in the North American annual killifish, Millerichthys robustus

open access: yesScientific Reports, 2022
Sex change (sequential hermaphroditism) has evolved repeatedly in teleost fishes when demographic conditions mediate fundamentally different sex-specific returns for individuals of particular age and size. We investigated the conditions for potential sex

Genomic Signatures Associated with Transitions to Viviparity in Cyprinodontiformes

open access: yesMolecular Biology and Evolution, 2022
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 ...
