Characterization of Mitochondrial Genomes and Evolutionary Relationships in Two <i>Moenkhausia</i> (Characiformes: Acestrorhamphidae). [PDF]

open access: yesEcol Evol
This study successfully decoded the complete mitochondrial genomes of two Moenkhausia species, with total lengths of 16,439 and 16,461 bp, respectively. This study enhances genomic resources for Acestrorhamphidae and provides a foundation for investigating evolutionary mechanisms and developing molecular markers.

Functional Morphology of the Oral Jaws and Dentition Across Diverse Diets and Ontogeny in Prickleback Fishes (Stichaeidae). [PDF]

open access: yesJ Morphol
Prickleback fishes (Stichaeidae) feed upon diverse diets, spanning carnivory (orange), omnivory (blue), and herbivory (green). We used microCT scanning to explore the functional morphology of the oral jaws and dentition across species and ontogeny. Focal species vary by morphotype and have divergent scaling patterns across diets.

Histamine in Brazilian Foods: A Comprehensive Review of Occurrence and Risk Assessment for Intoxication and Intolerance. [PDF]

open access: yesFood Sci Nutr
Even though histamine plays an important role in human health, it has been associated with food intoxication and intolerance episodes. The most relevant, current state of knowledge regarding histamine's biochemical and health aspects is provided. Histamine levels are provided for 17 food groups, including 335 food types and 11,437 samples, allowing ...

Karyotype differentiation and cytotaxonomic considerations in species of Serrasalmidae (Characiformes) from the Amazon basin [PDF]

open access: yesNeotropical Ichthyology, 2012
Six species of Serrasalmidae from the central Amazon, representatives of the genera Serrasalmus (S. elongatus, S. maculatus, S. cf. rhombeus, and S. rhombeus), Pygocentrus (P. nattereri), and Colossoma (C.

Ultrastructure of sonic muscles of piranhas (Serrasalmidae) [PDF]

open access: yesJournal of Morphology, 2022
Abstract Among piranhas, different species are able to produce sounds but not all of them use the same mechanism. In all species, the sound‐producing muscle originates on the second vertebra, but the insertion differs.

Genomics of Serrasalmidae teleosts through the lens of microbiome fingerprinting [PDF]

open access: yesMolecular Ecology, 2021
AbstractAssociations between host genotype and host‐associated microbiomes have been shown in a variety of animal clades, but studies on teleosts mostly show weak associations. Our study aimed to explore these relationships in four sympatric Serrasalmidae (i.e., piranha) teleosts from an Amazonian lake, using data sets from the hosts genomes (single ...

A typical enzyme activity for glutathione conjugation indicates exposure of pacu to pollutants

open access: yesNeotropical Ichthyology, 2022
Functional enzyme assays to detect sublethal poisoning of Neotropical fish are paramount. Accordingly, we assayed a glutathione S-transferase (GST) activity in liver and kidney cytosols from Piaractus mesopotamicus injected with methyl parathion or benzo[
