Comparative Satellitomics in Arowanas (Telostei, Osteoglossiformes) Sheds Light on the Evolution of Ancient Satellite DNAs

Integrative Zoology, EarlyView.
This work focused on arowana fishes (Teleostei, Osteoglossiformes) as a model; their widespread intercontinental distribution and basal phylogenetic position within Teleostei make them a compelling model for evolutionary research, especially in the realm of satDNA molecular evolution. Through the integration of genomic and chromosomal data, we analyzed

The Complete Genome Sequences of 38 Species of Elephantfishes (Mormyridae, Osteoglossiformes) [PDF]

Biodivers Genomes, 2022
We present the complete genome sequences of 38 species of elephantfishes from 20 genera. Illumina sequencing was performed on genetic material from single wild-caught individuals. The reads were assembled using a de novo method followed by a finishing step.

Cytogenetics, genomics and biodiversity of the South American and African Arapaimidae fish family (Teleostei, Osteoglossiformes). [PDF]

PLoS ONE, 2019
Osteoglossiformes represents one of the most ancestral teleost lineages, currently widespread over almost all continents, except for Antarctica. However, data involving advanced molecular cytogenetics or comparative genomics are yet largely limited for ...

Exceptionally Steep Brain-Body Evolutionary Allometry Underlies the Unique Encephalization of Osteoglossiformes [PDF]

Brain, Behavior and Evolution, 2021
Brain-body static allometry, which is the relationship between brain size and body size within species, is thought to reflect developmental and genetic constraints.

Feeding Ecology of Osteoglossum bicirrhosum (Osteoglossiformes: Osteoglossidae) in a Central Amazon Reserve [PDF]

Anais da Academia Brasileira de Ciências
Studies determining the feeding habits of fish are essential for understanding the relationships between fauna components and other aquatic organisms. This study aimed to evaluate the feeding habits of the Arowana Osteoglossum bicirrhosum in the Piranha ...

Molecular Ecology Resources, 2009
Abstract Osteoglossum bicirrhosum (silver arowana) is an important fish for the economy of the Amazon region, both as an ornamental fish and as a food fish. To provide tools for addressing ecological and genetic questions, we developed 19 polymorphic microsatellite markers that had between 2 and 7 alleles per locus in the 24 tested individuals.

Genetic variability and population structure of Osteoglossum bicirrhosum (Osteoglossiformes: Osteoglossidae) in the Amazon basin [PDF]

Neotropical Ichthyology
This study tested the hypothesis that the silver arowana from different rivers in the Amazon basin is genetically structured, thus requiring differentiated management strategies to maintain stocks and continue economic activities. Such activities include
