First record of Nubensia nubens (Edwards, 1929) (Diptera: Chironomidae) for Bulgaria

open access: yesCHIRONOMUS Journal of Chironomidae Research, 2020
Nubensia nubens (Edwards 1929) is reported for the first time in Bulgaria from two lowland rivers, tributaries of the Danube (eastern Europe). Larvae of the species were found incidentally in samples collected for an ichthyological study, in the gut ...

The Diversity of Ray-finned Fishes (Actinopterygii) in Plio-Pleistocene Java

open access: yesJournal of Tropical Biodiversity and Biotechnology, 2020
Java has been known in the world of Paleontology as a contributor to the findings of Homo erectus fossils, but there are still other fossil findings that have not been identified until now, especially fossil fishes of the subclass Actinopterygii. This research was conducted to recognize the diversity of the actinopterygians fishes in Plio-Pleistocene ...

Preferential accumulation of sex and Bs chromosomes in biarmed karyotypes by meiotic drive and rates of chromosomal changes in fishes

open access: yesAnais da Academia Brasileira de Ciências, 2014
Mechanisms of accumulation based on typical centromeric drive or of chromosomes carrying pericentric inversions are adjusted to the general karyotype differentiation in the principal Actinopterygii orders. Here, we show that meiotic drive in fish is also

Diet composition of a native fish species in a neotropical lentic environment

open access: yesActa Scientiarum: Biological Sciences, 2023
Native species are important to the dynamics of aquatic environments. Studies that seek to understand the basic biology of these species provide information on the species and the dynamics of the natural environment.

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 ...

A new genus of coccolepidid fishes (Actinopterygii, Chondrostei) from the continental Jurassic of Patagonia [PDF]

open access: yesPalaeontologia Electronica, 2013
Jurassic freshwater fish faunas are still poorly known, with the only assemblage of that age known from southern South America being the "Almada fauna" of the Canadon Calcareo Formation (Oxfordian-Tithonian) of Chubut, Argentina. This fauna is composed mainly by abundant teleosts and a much rarer basal actinopterygian, originally described as ...
