First record of Peacock bass Cichla kelberi Kullander & Ferreira, 2006 in the Brazilian Pantanal

BioInvasions Records, 2015
Biological invasions impact many communities and ecosystems around the world. Thus, the detection of harmful species is particularly important. In this study, the occurrence of Peacock bass Cichla kelberi in the Brazilian Pantanal was registered. The main stream of the Paraguay River, the Padre Inacio stream and their connected lakes were sampled, in ...

Analysis of propagule pressure and genetic diversity in the invasibility of a freshwater apex predator: the peacock bass (genus Cichla)

Neotropical Ichthyology
An important step in invasive biology is to assess biological variables that could be used to predict invasion success. The study of genetics, evolution, and interactions of invasive and native species in invaded ranges provides a unique opportunity to ...

The more stirring the better: cichlid fishes associate with foraging potamotrygonid rays

Neotropical Ichthyology
One hunting tactic of freshwater rays (Potamotrygonidae), termed "undulate the disc and stir substrate", is here reported to attract cichlids at two sites in the upper Paraná River.

Spatio-temporal segregation and size distribution of fish assemblages as related to non-native species occurrence in the middle rio Doce Valley, MG, Brazil

Neotropical Ichthyology
The lakes in the middle rio Doce Valley (MG) are suffering impacts due to the introduction of invasive fish species, mainly piscivorous species like red piranha Pygocentrus nattereri and peacock bass Cichla kelberi.
