Diversification Rate is Associated with Rate of Molecular Evolution in Ray-Finned Fish (Actinopterygii). [PDF]
J Mol Evol, 2022 Understanding the factors that drive diversification of taxa across the tree of life is a key focus of macroevolutionary research. While the effects of life history, ecology, climate and geography on diversity have been studied for many taxa, the ...

First Evidence of Microplastic Contamination in Antarctic Fish (Actinopterygii, Perciformes) [PDF]
Water, 2022 Microplastic (MP) pollution in Antarctica is a hot topic that has gained increasing attention in recent years. However, information regarding MP pollution in Antarctic fishes is currently very limited. The present study provides the first evidence of the

Alteration of the feeding behavior of an omnivorous fish, Scardinius acarnanicus (Actinopterygii: Cypriniformes: Cyprinidae), in the presence of fishing lights [PDF]
Acta Ichthyologica et Piscatoria, 2021 Fishing with light is an old and common practice yielding a substantial catch volume globally. Despite the popularity of the method and the efforts to improve it, there is a lack of field studies on the effects of light on the feeding preferences of the ...

The mitochondrial genome of the bioluminescent fish Malacosteus niger Ayres, 1848 (Stomiidae, Actinopterygii) is large and complex, and contains an inverted-repeat structure [PDF]
ZooKeys, 2023 Abstract We determined the complete mitogenome sequence of the bioluminescent fish Malacosteusniger using long-read sequencing technologies. The 21,263 bp mitogenome features a complex structure with two copies of a 1198-bp inverted-repeat and a region ...

Cestode and nematode larvae of hygienic-sanitary importance parasitizing Percophis brasiliensis (Actinopterygii) collected from fish markets of the municipality of Niterói, RJ, Brazil [PDF]
Food Science and Technology, 2021 Percophis brasiliensis is a fish species appreciated as a fried appetizer at beachside kiosks of Niteroi, state of Rio de Janeiro, Brazil. The constant presence of helminth larvae in the viscera and serosa of individuals of the species has been the ...

Shearing Tooth Morphology May Allow Sharks to Access Higher Trophic Levels at Smaller Sizes. [PDF]
Ecol EvolPredator morphology imposes limitations on prey selection due to biomechanical constraints, making some prey functionally inaccessible and thereby constraining predator trophic niches. We assessed how two key components of trophic morphology—tooth shape and body size—affect prey selectivity and trophic niche in two sympatric sharks with contrasting ...

Bioecology of Electric Fish (Actinopterygii: Gymnotiformes)
Middle East Research Journal of Biological SciencesThe poraquê has an elongated and cylindrical body, with just one anal fin, which extends across almost the entire abdomen it resembles the shape of an eel. Its head is flat and its mouth is equipped with a row of sharp, conical teeth.

The Anatomical Record, EarlyView.Abstract Actinopterygii is a major extant vertebrate group, but limited data are available for its earliest members. Here we investigate the morphology of Devonian actinopterygians, focusing on the lower jaw. We use X‐ray computed tomography (XCT) to provide comprehensive descriptions of the mandibles of 19 species, which span the whole of the Devonian

Aquatic eDNA outperforms sedimentary eDNA for the detection of estuarine fish communities in subtropical coastal vegetated ecosystems. [PDF]
J Fish BiolAbstract In South Africa, mangrove forests and seagrass meadows often co‐occur in estuarine systems and in combination host rich, often endemic biodiversity. There is an urgent need to explore community diversity in coastal vegetated ecosystems, given the degrading effects of climate change and anthropogenic pressures.
