Diversification Rate is Associated with Rate of Molecular Evolution in Ray-Finned Fish (Actinopterygii). [PDF]
J Mol Evol, 2022 AbstractUnderstanding 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 relationship between molecular evolution and diversification has received less attention.

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 attracted fishes.

Hydrological Connectivity Enhances Fish Biodiversity in Amazonian Mining Ponds: Insights From eDNA and Traditional Sampling. [PDF]
Mol EcolABSTRACT Artisanal and small‐scale gold mining (ASGM) expansion in the Madre de Dios region of the Peruvian Amazon has transformed primary forests into a novel wetland complex of thousands of abandoned mining ponds. Despite their ecological relevance, post‐mining recovery of these systems remains understudied, particularly regarding fish biodiversity ...

Fish species lifespan prediction from promoter cytosine‐phosphate‐guanine density
Molecular Ecology Resources, EarlyView., 2023 Abstract Lifespan is a key attribute of a species' life cycle and varies extensively among major lineages of animals. In fish, lifespan varies by several orders of magnitude, with reported values ranging from less than 1 year to approximately 400 years.

Molecular Ecology Resources, EarlyView., 2023 Abstract Conservation genomic studies in non‐model organisms generally rely on reduced representation sequencing techniques based on restriction enzymes to identify population structure as well as candidate loci for local adaptation. While the expectation is that the reduced representation of the genome is randomly distributed, the proportion of the ...

IsNematocharax(Actinopterygii, Characiformes) a monotypic fish genus? [PDF]
Genome, 2016 The combination of DNA barcodes and geometric morphometrics is useful to discriminate taxonomically controversial species, providing more precise estimates of biodiversity. Therefore, our goal was to assess the genetic and morphometric diversity in Nematocharax, a controversial monotypic and sexually dimorphic genus of Neotropical fish, based on ...

Larval development of Characidium orientale (Actinopterygii: Crenuchidae) a small Neotropical fish
Iheringia. Série Zoologia, 2022 ABSTRACT The Characidium orientale Buckup & Reis, 1997 larvae development is described using specimens collected in the natural environment of Antas River, in the Taquari-Antas river basin, Rio Grande do Sul, Brazil. Were considerate ontogenetic changes in morphology, pigmentation, fin morphology, and meristic characters.

Bony labyrinth morphology in early neopterygian fishes (Actinopterygii: Neopterygii) [PDF]
Journal of Morphology, 2016 ABSTRACTEndocasts of the osseous labyrinth have the potential to yield information about both phylogenetic relationships and ecology. Although bony labyrinth morphology is well documented in many groups of fossil vertebrates, little is known for early Neopterygii, the major fish radiation containing living teleosts, gars and the bowfin.

Developmental changes of opsin gene expression in ray-finned fishes (Actinopterygii)
Proceedings of the Royal Society B: Biological Sciences, 2022 AbstractFish often change their habitat and trophic preferences during development. Dramatic functional differences between embryos, larvae, juveniles and adults also concern sensory systems, including vision. Here we focus on the photoreceptors (rod and cone cells) in the retina and their gene expression profiles during the development.
