The chromosomes of the dogtooth characins, fish species of the family Cynodontidae, have only a relatively small amount of heterochromatin, including the terminal portion. Curiously, in the cynodontid Cynodon gibbus, the terminal portion is rich in r

Despite conservation of the diploid number, a huge diversity in karyotype formulae is found in the Ancistrini tribe (Loricariidae, Hypostominae). However, the lack of cytogenetic data for many groups impairs a comprehensive understanding of the chrom

Comparative cytogenetic of six species of Amazonian Peacock bass (Cichla, Cichlinae): intrachromosomal variations and genetic introgression among sympatric species

Autor: Patrik F. Viana, Alex M.V. Ferreira, Eliana Feldberg, Janice Quadros, Efrem J. G. Ferreira, Leandro Marajó, Ezequiel Aguiar de Oliveira

Comparative Cytogenetics 14(3): 437-451

Cytogenetic data for the genus Cichla Bloch et Schneider, 1801 are still very limited, with only four karyotype descriptions to date. The sum of the available cytogenetic information for Cichla species, points to a maintenance of the diploid number o

Transposable DNA Elements in Amazonian Fish: From Genome Enlargement to Genetic Adaptation to Stressful Environments

Autor: Francijara Araújo da Silva, Eliana Feldberg, Erika Milena Corrêa Guimarães, Natália Dayane Moura Carvalho, Gislene Almeida Carvalho-Zilse, Alex M.V. Ferreira, Carlos Henrique Schneider, Maria Claudia Gross

Publikováno v: Cytogenetic and Genome Research. 160:148-155

Transposable elements have driven genome evolution and plasticity in many ways across a range of organisms. Different types of biotic and abiotic stresses can stimulate the expression or transposition of these mobile elements. Here, we cytogeneticall

Chromosomal Mapping of Rex Retrotransposons in Tambaqui (Colossoma macropomum Cuvier, 1818) Exposed to Three Climate Change Scenarios

Autor: Alex M.V. Ferreira, Daniele Aparecida Matoso, Eliana Feldberg, Leandro Marajó, Leila Braga Ribeiro

Publikováno v: Cytogenetic and Genome Research. 159:39-47

Greenhouse gas emissions are known to influence the planet's temperature, mainly due to human activities. To allow hypothesis testing, as well as to seek viable alternatives for mitigation, the Intergovernmental Panel on Climate Change (IPCC) suggest

DNA barcoding proposes that a fragment of DNA can be used to identify species. In fish, a fragment of cytochrome oxidase subunit I (COI) has been effective in many studies with different foci. Here we use this molecular tool to provide new insights i
