A Hiatus Obscures the Early Evolution of Modern Lineages of Bony Fishes

open access: yesFrontiers in Earth Science, 2021
About half of all vertebrate species today are ray-finned fishes (Actinopterygii), and nearly all of them belong to the Neopterygii (modern ray-fins). The oldest unequivocal neopterygian fossils are known from the Early Triassic.

The Fossil Record of Ray-Finned Fishes (Actinopterygii) in Greece [PDF]

open access: yes, 2021
AbstractThe nowadays hyper-diverse clade of Actinopterygii (ray-finned bony fishes) is characterized by a long evolutionary history and an extremely rich global fossil record. This work builds upon 170 years of research on the fossil record of this clade in Greece. The taxonomy and spatiotemporal distribution of the ray-finned fish record of Greece are

Evidence for reproductive senescence across ray-finned fishes: A review

open access: yesFrontiers in Ecology and Evolution, 2022
The origin, incidence, and consequences of reproductive senescence vary greatly across the tree of life. In vertebrates, research on reproductive senescence has been mainly focused on mammals and birds, demonstrating that its variation is largely linked ...

Investigating otolith mass asymmetry in six benthic and pelagic fish species (Actinopterygii) from the Gulf of Tunis

open access: yesActa Ichthyologica et Piscatoria, 2021
Otolith mass asymmetry can significantly affect the vestibular system functionalities; usually, the X values of mass asymmetry vary between −0.2 and + 0.2 (−0.2 < X < + 0.2).

Phylogenetic relationships of freshwater fishes of the genus Capoeta (Actinopterygii, Cyprinidae) in Iran [PDF]

open access: yesEcology and Evolution, 2016
AbstractThe Middle East contains a great diversity of Capoeta species, but their taxonomy remains poorly described. We used mitochondrial history to examine diversity of the algae‐scraping cyprinid Capoeta in Iran, applying the species‐delimiting approaches General Mixed Yule‐Coalescent (GMYC) and Poisson Tree Process (PTP) as well as haplotype network
