Introduction
Currently develop a project with the order Crocodylia, using cytogenetic and molecular tools, trying to understand the chromosomal evolution and biogeographic aspects of these individuals.

Article
Full-text available
Background Crocodilians are one of the oldest extant vertebrate lineages, exhibiting a combination of evolutionary success and morphological resilience that has persisted throughout the history of life on Earth. This ability to endure over such a long geological time span is of great evolutionary importance. Here, we have utilized the combination o...
Article
Cardinalfishes are a diverse family of small fish found in reef habitats. Some species exhibit bioluminescence and unusual characteristics of buccal egg incubation. Cytogenetic data on the family are confined to Pacific species but reveal remarkable karyotype diversity, as highlighted by low diploid values (2n = 34–46), which likely resulted from c...
Article
Full-text available
Crocodilians have maintained very similar karyotype structures and diploid chromosome numbers for around 100 million years, with only minor variations in collinearity. Why this karyotype structure has largely stayed unaltered for so long is unclear. In this study, we analyzed the karyotypes of six species belonging to the genera Crocodylus and Oste...

Full-text available
Miniature fishes have always been a challenge for cytogenetic studies due to the difficulty in obtaining chromosomal preparations, making them virtually unexplored. An example of this scenario relies on members of the family Lebiasinidae which include miniature to medium-sized, poorly known species, until very recently. The present study is part of...
Article
Full-text available
A remarkable morphological diversity and karyotype variability can be observed in the Neotropical armored catfish genus Harttia. These fishes offer a useful model to explore both the evolution of karyotypes and sex chromosomes since many species possess male-heterogametic sex chromosome systems and a high rate of karyotype repatterning. Based on th...
Article

Although crocodilians have attracted enormous attention in other research fields, from the cytogenetic point of view, this group remains understudied. Here, we analyzed the karyotypes of eight species formally described from the Alligatoridae family using differential staining, flu-orescence in situ hybridization with rDNA and repetitive motifs as...
Article
Full-text available
In the fish genus Hoplias, two major general groups can be found, one of which is formed by the “common trahiras” (Hoplias malabaricus group) and the other by the “giant trahiras” (Hoplias lacerdae group, in addition to Hoplias aimara), which usually comprises specimens of larger body size. Previous investigations from the giant trahiras group reco...

The Amazon aquatic ecosystems have been modified by the human population growth, going through changes in their water bodies and aquatic biota. The spectacled alligator (Caiman crocodilus crocodilus) has a wide distribution and adaptability to several environments, even those polluted ones. This study aimed to investigate if a Caiman species living...
