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, SébastienThe 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...
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, TerumiOsteoglossiformes 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...
Historical demography and climate driven distributional changes in a widespread...
Oliveira, Ezequiel Aguiar de; Perez, Manolo Fernandez; Bertollo, Luiz Antônio Carlos; Gestich, Carla C.; Ráb, Petr; Ezaz, Tariq Tariq; Souza, F. H.S.The Neotropical region exhibits the greatest worldwide diversity and the diversification history of several clades is related to the puzzling geomorphologic and climatic history of this region. The freshwater Amazon ecoregion contains the main hydrographic basins of the Neotropical region that are highly dendritic and ecologically diverse. It contains a rich and endemic fish fauna, including one of its most ico...
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, ElianaAmazonian 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...
Deciphering the evolutionary history of arowana fishes (Teleostei, osteoglossif...
Cioffi, Marcelo de Bello; Ráb, Petr; Ezaz, Tariq Tariq; Bertollo, Luiz Antônio Carlos; Lavoué, Sébastien; Oliveira, Ezequiel Aguiar de; Sember, AlexandrArowanas (Osteoglossinae) are charismatic freshwater fishes with six species and two genera (Osteoglossum and Scleropages) distributed in South America, Asia, and Australia. In an attempt to provide a better assessment of the processes shaping their evolution, we employed a set of cytogenetic and genomic approaches, including i) molecular cytogenetic analyses using C-and CMA3/DAPI staining, repetitive DNA mappi...
