Rineloricaria is the most diverse genus within the freshwater fish subfamily Loricariinae, and
it is widely distributed in the Neotropical region. Despite limited cytogenetic data, records …

The Neotropical monophyletic catfish genus Harttia represents an excellent model to study
karyotype and sex chromosome evolution in teleosts. Its species split into three phylogenetic …

Cytogenetic studies demonstrated that unstable chromosomal sites in armored catfishes
(Loricariidae) triggered intense karyotypic diversification, mainly derived from Robertsonian …

Chromosomal rearrangements play a significant role in the evolution of fish genomes, being
important forces in the rise of multiple sex chromosomes and in speciation events. Repetitive …

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 …

Despite several difficulties in chromosomal analyses of small-sized fishes, the cytogenetics
of the Lebiasinidae was largely improved in the last years, showing differential patterns in …

The Neotropical monophyletic catfish genus Harttia represents an excellent model to study
karyotype and sex chromosome evolution in teleosts. Its species split into three phylogenetic …

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 …

Allopatry is generally considered to be one of the main contributors to the remarkable
Neotropical biodiversity. However, the role of chromosomal rearrangements including neo …

Miniature refers to species with extraordinarily small adult body size when adult and can be
found within all major metazoan groups. It is considered that miniature species have …
