Abstract The extent and intensity of impacts of multiple new dams in the Amazon basin on specific biological groups are potentially large, but still uncertain and need to be better understood. It is known that river disruption and regulation by dams may affect sediment supplies, river channel migration, floodplain dynamics, and, as a major adverse ...

Possible Common Origin of B Chromosomes in Neotropical Fish (Siluriformes, Auchenipteridae) Reinforced by Repetitive DNA Mapping [PDF]
The aim of this paper was to present the second case of B chromosomes in Auchenipteridae (Trachelyopterus sp.), and to test the hypothesis that the B chromosomes of this species and Parauchenipterus galeatus might have a common origin, since these two ...

Early ontogeny and swimming behavior of larvae of the neotropical fish Prochilodus costatus Valenciennes 1850 and Prochilodus argenteus Spix & Agassiz 1829 (Characiformes: Prochilodontidae) [PDF]
Early development of fish larvae is a highly dynamic process and its study may provide important information about ontogenetic development, bioenergetic growth, behaviour, taxonomic characteristics for identification in natural environments ...

Auchenipteridae There are six auchenipterid species inhabiting the upper rio Paraná, distributed in the genera Ageneiosus, Auchenipterus, and Trachelyopterus. Two Ageneiosus species colonized the upper Paraná after the Itaipu impoundment: A. inermis (formerly called A. brevifilis) and A. ucayalensis.
