The Tubarão River rises in Santa Catarina, Brazil, and has been historically affected by coal mining activities around its springhead. To evaluate its water conditions, an investigation regarding a possible decontamination gradient associated with the increased river flow toward the estuary, as well as the influence of seasonality over this gradient ...

The ornamental stone industry generates considerable amounts of waste (OSPW), which may eventually reach natural environments and impact the local ecosystem. The aim of this study was to compare the toxic effects of two OSPW effluents in Geophagus brasiliensis: i) leachate effluent from a lagoon in an OSPW landfill (LE) and ii) decanted effluent from ...

Lead is toxic to fish, and its toxicity can be aggravated by the water temperature. Geophagus brasiliensis populations are geographically widespread and thus live in areas with different temperatures. The objective of this work was to evaluate the effects of lead-contaminated feed in fish (Geophagus brasiliensis) exposed to different temperatures.

Journal of Fish Biology, 2013
Fourteen polymorphic microsatellite loci were isolated and characterized for the Neotropical cichlid Geophagus brasiliensis and tested on 30 individuals belonging to a single population. Among the 14 loci described, four showed potential presence of null alleles, inferred from the excess of homozygous genotypes, and three of these loci showed ...

Studies on Neotropical Fauna and Environment, 2014
The aim of this study was to analyze the trophic interactions between the population of the native fish Geophagus brasiliensis and the benthic macroinvertebrate community in the Broa Reservoir, Sao Paulo State, Brazil. The data obtained showed that the macroinvertebrates are used frequently as a source of food by the G.

The feeding habits, comportment and geographical distribution of host are factors that may contribute to parasite faunas rich in species. For characterize de parasite fauna of Geophagus brasiliensis and know the host-parasite relationships were necropsied 64 fishes from nine reservoirs of the Paraná State (Brazil).
