Ecological niche modeling as an effective tool to predict the distribution of freshwater organisms: The case of the Sabaleta Brycon henni (Eigenmann, 1913) [PDF]
Ecological niche models (ENMs) aim to recreate the relationships between species and the environments where they occur and allow us to identify unexplored areas in geography where these species might be present.

The sabaleta, Brycon henni, is a medium-size fish species found in the Andean range of the Magdalena-Cauca river basin in Colombia, where it is a fishery resource. Recruitment of sabaleta has affected construction of dams with unknown consequences on its

Morphological and molecular characterization of Contracaecum jorgei (Nematoda: Anisakidae) in five Neotropical freshwater fish species in Colombia [PDF]
Larvae of the family Anisakidae occur in numerous freshwater and marine fish species. Although nematodes of the genus Contracaecum are widely distributed, little is known about their occurrence in fish in South America, particularly in Colombia.

Feeding strategy of fish that colonize reservoirs in the Magdalena river basin
Construction of dams for hydropower in Andean rivers of Colombia is increasing loss of species of the region. Fish species that persist in these artificial ecosystems are those which find favorable the new conditions for their recruitment.

Ecological Factors and Diversification among Neotropical Characiforms
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. We explore potential primary morphological factors controlling the early diversification process in some Neotropical characiforms as
