Abstract Purpose of Review Fishes exhibit the greatest biodiversity among extant
vertebrates. In fact, about 34,000 fish species are currently estimated, of which~ 25% are …

Bunocephalus is the most species-rich Aspredinidae genus, corresponding to a
monophyletic clade with 13 valid species. However, many species have their classification …

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 …

In the marine environment, pelagic ecosystems are vast and complex, with their biodiversity
still being underestimated. In these regions, specifically in mesopelagic zones, the …

Lebiasinidae is a Neotropical freshwater family widely distributed throughout South and
Central America. Due to their often very small body size, Lebiasinidae species are …

We analyzed one Bunocephalus coracoideus population from the Negro River basin using
cytogenetic techniques. The results showed a diploid number of 42 chromosomes in both …

We describe Myxobolus cataractae n. sp., found parasitizing Imparfinis mirini from
Cachoeirinha stream, a tributary of Pardo River, Paraná River basin, municipality of …

Physical map** of repetitive DNA families in the karyotypes of fish is important to
understand the organization and evolution of different orders, families, genera, or species …

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 …

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 …
