Testing the ecomorphological hypothesis in a headwater riffles fish assemblage of the rio São Francisco, southeastern Brazil [PDF]

Neotropical Ichthyology, 2006
The ecomorphology of 14 fish species resident in a headwater riffles area of the São Francisco river, southeastern Brasil, was analyzed and combined with diet and feeding behavior data, previously obtained by us. The three larger species groups formed in

Feeding of two sympatric species of Characidium, C. lanei and C. pterostictum (Characidiinae) in a coastal stream of Atlantic Forest (Southern Brazil)

Brazilian Archives of Biology and Technology, 2000
The feeding strategy of Characidium lanei and C. pterostictum was studied in the "Cabral" stream, a coastal stream of the Atlantic Forest, in southern Brazil. The samples were taken using electric fishing between March/95 and February/96.

Populations of Characidium rachovii (Crenuchidae: Characidiinae) with reduction of the adipose fin from Argentina and a Southernmost record of C. occidentale

, 2006
The objective of this note is to report on populations of Characidium rachovii with reduction and absence of the adipose fin from Salí-Dulce and Paraná River basins, Argentina. In addition, we make considerations about the use of this character as diagnostic at the alpha level and mention the occurrence of Characidium occidentale Buckup & Reis in the ...
