Ecological Factors and Diversification among Neotropical Characiforms [PDF]
International Journal of Ecology, Volume 2012, Issue 1, 2012., 2012 Morphological and DNA sequence data has been used to propose hypotheses of relationships within the Characiformes with minimal comparative discussion of causes underpinning the major intraordinal diversification patterns.

Osmolality and composition of the extender during the cold storage of Prochilodus lineatus (Characiformes: Prochilodontidae) sperm [PDF]
Neotropical Ichthyology, 2014 This study evaluates the effects of extender osmolality and composition on the cooling of Prochilodus lineatussperm. Sperm was diluted in six extenders: two compositions (powdered coconut water(tm) = ACP; Beltsville Thawing Solution(tm) = BTS) x three osmolalities (285, 325, and 365 mOsm/kg) plus an undiluted control, and stored at 6-8°C. Motility rate

Molecular phylogenetics of the Neotropical fish family Prochilodontidae (Teleostei: Characiformes) [PDF]
Molecular Phylogenetics and Evolution, 2016 Migratory detritivores of the characiform family Prochilodontidae occur throughout the freshwaters of much of South America. Prochilodontids often form massive populations and many species achieve substantial body sizes; a combination that makes them one of the most commercially important fish groups on the continent.

Acute toxicity of the water-soluble fraction of diesel in Prochilodus vimboidesKner (Characiformes: Prochilodontidae) [PDF]
Neotropical Ichthyology, 2013 Diesel oil can be a source of contamination in aquatic environments, mainly as a result of spills. The effects of the water-soluble fraction of diesel (WSF) on Prochilodus vimboideswere assessed.
