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.

Male Copulatory Structures in Reproductively Functional Female Live-Bearing Fish <i>Pseudopoecilia fria</i>. [PDF]

Ecol Evol
We 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 Embryol
ABSTRACT 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.

Precipitation Modulates the Impact of Human Activities on Riverine Food Webs Revealed by Environmental DNA. [PDF]

Ecol Evol
The effects of human activities on ecological networks are associated with climate, with increased precipitation weakening their negative impact. ABSTRACT The functionality of global rivers has been adversely affected by environmental pollution and habitat degradation.

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

Scientific 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

Life in the fastlane? A comparative analysis of gene expression profiles across annual, semi-annual, and non-annual killifishes (Cyprinodontiformes: Nothobranchiidae). [PDF]

PLoS One
The Turquoise Killifish is an important vertebrate for the study of aging and age-related diseases due to its short lifespan. Within Nothobranchiidae, species possess annual, semi-annual, or non-annual life-histories.
