Revealing the Satellite DNA History in Psalidodon and Astyanax Characid Fish by Comparative Satellitomics

Frontiers in Genetics, 2022
Eukaryotic genomes are usually enriched in repetitive DNA sequences, which can be classified as dispersed or tandemly repeated elements. Satellite DNAs are noncoding monomeric sequences organized in a head-to-tail fashion that are generally located on ...

Liver-derived cell lines from cavefish Astyanax mexicanus as an in vitro model for studying metabolic adaptation

Scientific Reports, 2022
Cell lines have become an integral resource and tool for conducting biological experiments ever since the Hela cell line was first developed (Scherer et al. in J Exp Med 97:695–710, 1953).

Establishing a model fish for the Neotropical region: The case of the yellowtail tetra Astyanax altiparanae in advanced biotechnology

Frontiers in Genetics, 2022
The use of model organisms is important for basic and applied sciences. Several laboratory species of fishes are used to develop advanced technologies, such as the zebrafish (Danio rerio), the medaka (Oryzias latipes), and loach species (Misgurnus spp.).

Genetic identification and reiterated captures suggest that the Astyanax mexicanus El Pachón cavefish population is closed and declining

bioRxiv, 2022
The size of Astyanax mexicanus blind cavefish populations of North-East Mexico is a demographic parameter of great importance for investigating a variety of ecological, evolutionary and conservation issues. However, very few estimates have been obtained.

Reproductive seasonality of Astyanax mexicanus cavefish

Zoological Research, 2022
The characiform fish Astyanax is a well-studied model system for understanding evolutionary development and genomics in cave biology. Nonetheless, considerable gaps remain in our understanding of its field ecology.

Divergent evolutionary pathways for aggression and territoriality in Astyanax cavefish

Subterranean Biology, 2022
The surface morph of the Mexican tetra fish (Astyanax mexicanus) exhibits strong territoriality behavior and high levels of aggression. In contrast, the eyeless cave-adapted morph from Sierra de El Abra, México, rarely are aggressive and have totally ...

Redescription of Astyanax goyacensis Eigenmann, 1908 (Ostariophysi: Characiformes: Characidae)

Neotropical Ichthyology
Astyanax goyacensis Eigenmann, 1908 is redescribed based on the holotype and 25 topotypes. The species belongs to the A. bimaculatus species complex, sharing with those species a black, horizontally ovate, humeral spot (the most conspicuous feature of ...
