Comparative cytogenetics among populations of Astyanax altiparanae (Characiformes, Characidae, Incertae sedis) [PDF]
Genetics and Molecular Biology, 2009 Cytogenetic data are presented for Astyanax altiparanae populations from three Brazilian hydrographic systems. The chromosomal data obtained in A. altiparanae support the hypothesis of diploid number conservation.

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

Cytogenetic analysis in the incertae sedis species Astyanax altiparanae Garutti and Britzki, 2000 and Hyphessobrycon eques Steindachner, 1882 (Characiformes, Characidae) from the upper Paraná river basin [PDF]
Comparative Cytogenetics, 2012 Cytogenetic analyses were accomplished in two populations of Astyanax altiparanae Garutti & Britzki, 2000 and one population of Hyphessobrycon eques Steindachner, 1882, considered incertae sedis in Characidae family. Two populations of A. altiparanae

Cytogenetic comparison between two allopatric populations of Astyanax altiparanae Garutti & Britski, 2000 (Teleostei, Characidae), with emphasis on the localization of 18S and 5S rDNA [PDF]
Comparative Cytogenetics, 2011 Two populations of Astyanax altiparanae (Garutti et Britski, 2000) of the Água dos Patos stream/SP and lake Igapó/PR were analyzed. All individuals showed 2n = 50, however, different karyotypic formulae were observed. The population of the &
