I completed my PhD in Biological Sciences (Biology-Genetics) from the University of São Paulo (USP) in 1991. I have worked at the Universidade Estadual Paulista Júlio de Mesquita Filho (UNESP) since 1989 and am currently a Full Professor. I am also a Research Associate at the National Museum of Natural History, Smithsonian Institute (USA) and the Instituto Nacional de Biodiversidad (Ecuador). I am a reviewer for several foundations and scientific journals and Assistant Editor of the journals Scientific Reports, Frontier in Genetics, Frontiers in Ecology and Evolution, Journal of Animal Diversity and Neotropical Ichthyology. I have published more than 400 articles in specialized magazines, several book chapters and a book. I have participated in several undergraduate courses in the area of #8203;#8203;Cellular and Molecular Biology and in postgraduate programs in the areas of Genetics and Zoology. I have been working with fish for the last 35 years, carrying out research in various fields such as: cytogenetics (chromosomes), population genetics, systematics, taxonomy, biogeography, ecology and evolutionary biology. The main focus of my research is fish biodiversity in the Neotropical region and, to this end, I have worked with many friends around the world to investigate this biodiversity and mainly study its origin and maintenance.

Stevardiinae is the second highest diverse characids subfamily, including 45 genera and 362 species valid. The subfamily is composed by small size with very striking sexual characteristics. Recent phylogenetic studies have revealed the monophyly of the family, which is currently, recognized in eight tribes. However, the phylogenetic relationship of many taxa, mainly those found in deep no…
Ostariophysi is one of the largest fish superorders, formed almost exclusively by freshwater species, with about 95 families, about 1,500 genera and 11,000 species, thus containing approximately 30% of the known fish species in the world and almost 70 % of freshwater species. Ostariophysi are present all over the world, except in Antarctica, where only fossils are known. Despite the great…
The inventory and description of the biodiversity of marine fish are important steps towards fulfilling international commitments assumed by Brazil, as the first signatory to the Convention on Biological Diversity, during the United Nations Conference on Environment and Development and a strategic issue considering that the unsatisfactory knowledge of the taxonomy of marine and estuarine …
Geographical barriers greatly influence the genetic isolation of some marine species, but the transposition of these barriers by some fish may occur, so that there is no change in the gene flow of the species. The estuarine environments may be related to the isolation of populations due, among other factors, to the stress of the salinity variation inherent to the estuaries, including for …
The knowledge of the marine species diversity is relatively complete in some regions of the world, especially regarding to families with the greatest commercial interest. However, important knowledge gaps still exist, especially in less studied areas, such as some areas of the Brazilian coast. Moreover, few molecular studies are addressing the diversity of coastal fish on the coast of Bra…

Overfishing imposes changes in the life strategies of organisms, especially elasmobranchs (sharks and rays) that have biological characteristics that make them vulnerable to mortality caused by human effects. Understanding the structure of populations becomes na importante tool for conservation and management of stocks, which requires a broad knowledge of genetic, biogeographic, distribut…
Excessive fishing imposes changes in the life strategy of populations of aquatic organisms, especially elasmobranchs such as sharks and rays. Thus, understanding the distribution of species and the structure of populations becomes an important tool for managing and conserving stocks that require knowledge about genetic, biogeographical aspects, distribution and occurrence of species. Hypa…
In Brazil, the genus Narcine is represented by the electric rays or numbfishes N. brasiliensis, classified according to their conservation status as "Vulnerable," and by a non-formally described species (Narcine sp.), which makes them a priority for research aimed at biodiversity conservation. The taxonomic status of species in the genus is still uncertain, and their genetic diversity and…

The Aspredinidae family is widely distributed in the Cis and Trans-Andean regions of South America. Currently, 48 valid species are recognized, popularly known as "banjo catfish" due to their body morphology consisting of a more robust anterior region of the body and thinning along the posterior region. Published Aspredinidae phylogenies still show inconsistencies in intergeneric and inte…
Brazil holds the greatest biological diversity on the planet, accounting for 10% to 20% of the total number of species in the world. Much of this diversity is distributed in terrestrial biomes, but very little is known about the areas of endemism of marine biodiversity in Brazil. The Carangidae family consists of about 150 species, belonging to 30 genera, distributed in the Atlantic, Indi…
Taxonomy is the discipline within biology responsible for the study of the diversity of organisms. Thus, the central priority in taxonomy research is the discovery and delimitation of species, which is the process of identifying and delineating distinct organic entities in nature. The rigor in the delimitation can be increased when complementary data of a different nature are used, such a…

With 171 currently valid species distributed throughout the Neotropical region, the genus Hyphessobrycon is the most species-rich genus in the order Characiformes. Recently placed in the subfamily Stethaprioninae, Hyphessobrycon is considered non-monophyletic. Morphological characters that define the genus, such as an incompletely-pored lateral line, unscaled caudal fin, and premaxilla wi…
The banjo catfish family Aspredinidae is characterized by having a distinctively shaped body that is anteriorly enlarged and dorsoventrally compressed with a narrow caudal peduncle. Aspredinidae is widely distributed throughout South American lowlands, with most species inhabiting freshwater rivers, streams, and lakes and some representatives of the tribe Aspredinini inhabiting coastal br…
Estuaries are used by many fish as breeding, feeding, spawning, and predator protection sites. Knowledge of spawning and recruitment areas, as well as the identification of ichthyoplankton, is essential to understand population dynamics in the environment, in addition to contributing to the protection of ichthyofauna and the management of fishery resources. Since traditional methods of id…
Siluriformes represents on of the most diverse vertebrate groups on our planet, with 4019 valid species and 500 genera assigned to 39 families. They occupy a wide variety of freshwater ecosystems and are distributed all continents. Systematists recognize three major clades within Siluriformes, the neotropical Loricarioidei and Diplomistoidei and the globally distributed clade Siluroidei, …
Neotropical freshwater fishes exhibit high diversity, and their evolutionary diversification is closely related to the geomorphological history of the heterogeneous watersheds in which they inhabit. Erythrinidae is a widely distributed family of Neotropical freshwater fishes, occurring in lentic and lotic habitats in most drainages of Central and South America, from Costa Rica to Argentin…
