Problems with the state of our knowledge of the phylogenetic history and species-level
diversity of the South and Central America freshwater ichthyofauna are discussed …

We provide a general compilation of the diversity and geographical distribution of
Amazonian fishes, updated to the end of 2018. Our database includes documented …

The eastern coastal basins of Brazil are a series of small and isolated rivers that drain
directly into the Atlantic Ocean. During the Pleistocene, sea-level retreat caused by …

Today, 93 percent of freshwater drainage off South America runs into the Atlantic. South
America's drainage pattern was shaped by its persistent Guyana and Brazilian continental …

The eastern Brazilian coastal drainages are of great biogeographical significance, because
of their highly endemic fish faunas. Phylogenetic patterns suggest a close biotic relationship …

Aim To investigate biogeographical patterns of the obligate freshwater fish order
Characiformes. Location South America. Methods Parsimony analysis of endemicity …

ABSTRACT Biogeography of Amazonian fishes (2,500 species in vastly disjunct lineages) is
complex and has so far been approached only partially. Here, we tackle the problem on the …

The genus Otocinclus Cope (1872) of the siluriform family Loricariidae is diagnosed as
monophyletic on the basis of shared derived characters of the cranial and hyobranchial …

Mitochondrial DNA (mtDNA) sequences were used to infer the phylogenetic relationships of
Prochilodus species in the Paraná, Amazonas, Orinoco, and Magdalena basins. Sequences …

As the depredation of the planet's greatest storehouse of biodiversity--the Amazon region--
continues apace, it is vitally important to understand the implications of the immense …
