Revealing the Satellite DNA History in Psalidodon and Astyanax Characid Fish by Comparative Satellitomics [PDF]
Frontiers in Genetics, 2022Eukaryotic 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 ...

Homeology of sex chromosomes in Amazonian Harttia armored catfishes supports the X-fission hypothesis for the X1X2Y sex chromosome system origin [PDF]
Scientific Reports, 2023The Neotropical monophyletic catfish genus Harttia represents an excellent model to study karyotype and sex chromosome evolution in teleosts. Its species split into three phylogenetic clades distributed along the Brazilian territory and they differ ...

Considerações sobre amostragem de peixes marinhos (I) [PDF]
Boletim do Instituto Oceanográfico, 1960A fishery research programme requires an accurate picture of the length distribution of the fish caught and landed. Each boat is considered a sampling unit. It is therefore necessary to know how to draw a sample from the fish landed in such a way as to give an accurate assessment of the length distribution of the boat's landing.
