Bioconcentration and bioaccumulation of metal in freshwater Neotropical fish Geophagus brasiliensis

Environmental Science and Pollution Research, 2014
From the concentration in water and sediments, bioconcentration and bioaccumulation of copper (Cu), manganese (Mn), zinc (Zn), iron (Fe), cobalt (Co), cadmium (Cd), chrome (Cr), silver (Ag), lead (Pb), nickel (Ni), aluminum (Al), and arsenic (As) were determined in the gills, liver, and muscles of Geophagus brasiliensis in the Alagados Reservoir, Ponta

Environmentally related life history variations in Geophagus brasiliensis

Journal of Fish Biology, 2002
The hypothesis of environmentally related life history variations between two Geophagus brasiliensis populations was investigated by comparing riverine and lacustrine populations. Mean standard length and length at maturity were higher in the lagoon population.

Cryptic Chromosomal Diversity in the Complex “Geophagus” brasiliensis (Perciformes, Cichlidae)

Zebrafish, 2016
Among American cichlids, Geophagus stands out as a species-rich genus widespread over neotropical region. Despite their diversity and confusing taxonomy, only few and basic chromosomal reports are available in populations/species along Atlantic coast, hindering our understanding about evolutionary trends in this genus.

Trends of karyotypical evolution in the pearl cichlid, Geophagus brasiliensis, from southern Brazil

Zoology, 2013
Chromosomal rearrangements such as inversions can facilitate speciation even in the presence of gene flow. The present study aims to analyze the karyotypic variation in six populations of Geophagus brasiliensis from southern Brazil. All specimens showed 2n=48 chromosomes, but three karyotypes were found to have one, two or three pairs of submetacentric
