Ferreira, Milena; Garcia, Caroline; Matoso, D. A.; Jesus, Isac Silva de; Cioffi, Marcelo de Bello; Bertollo, Luiz Antônio Carlos; Zuanon, Jansen

Bunocephalus is the most species-rich Aspredinidae genus, corresponding to a monophyletic clade with 13 valid species. However, many species have their classification put in question. Here, we analyzed individuals from four Amazonian populations of Bunocephalus coracoideus by cytogenetic and molecular procedures. The geographic distribution, genetic distances and karyotype data indicate that each population rep...

Interspecific genetic differences and historical demography in South American a...

Souza, Fernando Henrique Santos de; Perez, Manolo Fernandez; Bertollo, Luiz Antônio Carlos; Oliveira, Ezequiel Aguiar de; Lavoué, Sébastien

The South American arowanas (Osteoglossiformes, Osteoglossidae, Osteoglossum) are emblematic species widely distributed in the Amazon and surrounding basins. Arowana species are under strong anthropogenic pressure as they are extensively exploited for ornamental and food purposes. Until now, limited genetic and cytogenetic information has been available, with only a few studies reporting to their genetic divers...

An Insight into the Chromosomal Evolution of Lebiasinidae (Teleostei, Characifo...

Sassi, Francisco de Menezes Cavalcante; Hatanaka, Terumi; Moraes, Renata Luiza Rde; Toma, Gustavo Akira; Oliveira, Ezequiel Aguiar de; Liehr, Thomas

Lebiasinidae fishes have been historically neglected by cytogenetical studies. Here we present a genomic comparison in eleven Lebiasinidae species, in addition to a review of the ribosomal DNA sequences distribution in this family. With that, we develop ten sets of experiments in order to hybridize the genomic DNA of representative species from the genus Copeina, Copella, Nannostomus, and Pyrrhulina in metaphas...

Toma, Gustavo Akira; Moraes, Renata Luiza Rosa de; Sassi, Francisco de Menezes Cavalcante; Bertollo, Luiz Antônio Carlos; Oliveira, Ezequiel Aguiar de

Lebiasinidae is a small fish family composed by miniature to small-sized fishes with few cytogenetic data (most of them limited to descriptions of diploid chromosome numbers), thus preventing any evolutionary comparative studies at the chromosomal level. In the present study, we are providing, the first cytogenetic data for the red spotted tetra, Copeina guttata, including the standard karyotype, C-banding, rep...

Cytogenetics, genomics and biodiversity of the South American and African Arapa...

Oliveira, Ezequiel Aguiar de; Bertollo, Luiz Antônio Carlos; Ráb, Petr; Ezaz, Tariq Tariq; Yano, Cassia Fernanda; Hatanaka, Terumi

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 this fish group. Therefore, the present investigations focus on the osteoglossiform family Arapaimidae, studying a unique fish model group with advanced molecula...

Extensive Chromosomal Reorganization in Apistogramma Fishes (Cichlidae, Cichlin...

Costa, Gideão Wagner Werneck Félix da; Cioffi, Marcelo de Bello; Liehr, Thomas; Feldberg, Eliana; Bertollo, Luiz Antônio Carlos; Molina, Wagner Franco

Neotropical cichlid fishes are one of the most diversified and evolutionarily successful species assemblages. Extremely similar forms and intraspecific polychromatism present challenges for the taxonomy of some of these groups. Several species complexes have a largely unknown origin and unresolved evolutionary processes. Dwarf cichlids of the genus Apistogramma, comprising more than a hundred species, exhibit i...

Evolutionary insights of the zw sex chromosomes in snakes: A new chapter added ...

Viana, Patrik Ferreira; Ezaz, Tariq Tariq; Cioffi, Marcelo de Bello; Almeida, Breno Jackson L.; Feldberg, Eliana

Amazonian puffing snakes (Spilotes; Colubridae) are snakes widely distributed in the Neotropical region. However, chromosomal data are scarce in this group and, when available, are only limited to karyotype description using conventional staining. In this paper, we focused on the process of karyotype evolution and trends for sex chromosomes in two Amazonian Puffer Snakes (S. pulllatus and S. sulphureus). We per...
