Genomic Insights Into Carnivorous Fish in the Characiformes. [PDF]

Ecol Evol
This study employed comparative genomic approaches using 12 high‐quality Characiformes genomes (covering nine subfamilies) with zebrafish as an outgroup to explore the molecular mechanisms underlying the carnivorous adaptation of Characiformes. Expanded gene families, positively selected genes, and rapidly evolving genes in carnivorous species were ...

Ossification of the cranium of Inpaichthys kerri (Characiformes: Acestrorhamphidae) with discussion of paedomorphic traits in the genus. [PDF]

J Anat
In this study, we present a detailed description of the cranial development of Inpaichthys kerri (Characiformes: Acestrorhamphidae), highlighting important topics such as pedomorphic characters and their relationship with ontogeny and phylogeny, as well as ossification sequences unique to the species. Abstract The study of development provides valuable

Eco-evolutionary factors that influence its demographic oscillations in Prochilodus costatus (Actinopterygii: Characiformes) populations evidenced through a genetic spatial-temporal evaluation. [PDF]

Evol Appl, 2023
Abstract The human activity impact on wild animal populations is indicated by eco‐evolutionary and demographic processes, along with their survival and capacity to evolve; consequently, such data can contribute toward enhancing genetic‐based conservation programs.

Early Biogeography of Otophysi Points to the Neotropics as the Cradle of Characiphysan Fishes. [PDF]

Ecol Evol
Otophysan fishes represent 70% of living freshwater fishes with 12,000 species. Relationships among their four orders were explored through a dense taxonomic sampling including 529 complete mitochondrial genomes and 4 nuclear genes for 324 species.

Ontogeny of the Skeleton of Leporinus oliveirai (Characiformes, Anotomidae). [PDF]

J Morphol
In this study, we provide the first complete description of the skeleton ontogeny of an anostomid. The developmental sequence of 141 bony elements is described and illustrated. The main discoveries are numerous conical teeth on the premaxilla and dentary that are replaced with three or four large incisiform multicuspid teeth, that become unicuspid in ...

Hydrological Connectivity Enhances Fish Biodiversity in Amazonian Mining Ponds: Insights From eDNA and Traditional Sampling. [PDF]

Mol Ecol
ABSTRACT 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 ...

Estimation of growth parameters of five fish species (Actinopterygii) caught in the central Amazon [PDF]

Acta Ichthyologica et Piscatoria, 2018
For some tropical fishes, the information on growth parameters is still scarce, and few or no records are available in FishBase. Therefore, the objective of this study was to estimate the growth curves for Brycon amazonicus (Spix et Agassiz, 1829 ...

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

Food 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 ...

Monogenéticos de Prochilodus nigricans (Prochilodontidae) no sudoeste da Amazônia

Acta Brasiliensis, 2023
Os monogenoideas são em grande parte ectoparasitas conhecidos por suas infestações em ambientes de piscicultura, encontrado em brânquias de peixes. A fauna de monogenéticos de P. nigricans, seja em ambientes naturais ou artificiais, foram relatados, porém poucos estudos abordaram o estudo de comunidade e distribuição da fauna desse ectoparasito.
