Spar genetic analysis of two invasive species of Cichla (Tucunaré) (Perciformes: Cichlidae) in the Paraná river basin = Análise genética via spar, de duas espécies de Cichla (Tucunaré) (Perciformes: Cichlidae) introduzidas na Bacia do rio Paraná

open access: yesActa Scientiarum: Biological Sciences, 2011
The introduction of exotic species in lake ecosystems has been greatly highlighted in the literature worldwide. Since introduction may threaten diversity of native fish, the issue turns up to be of paramount importance.

Molecular identification of species of the cichla genus (cichliformes: Cichlidae) Introduced into river basins in Maranhão

open access: yes, 2022
The inference on the origin of fish stocks introduced outside their habitat with a phylogenetic approach constitutes an important step in understanding and controlling the expansion of invasive species.

Experimental assessment of the effects of a Neotropical nocturnal piscivore on juvenile native and invasive fishes

open access: yesNeotropical Ichthyology
We experimentally examined the predator-prey relationships between juvenile spotted sorubim Pseudoplastystoma corruscans and young-of-the-year invasive and native fish species of the Paraná River basin, Brazil. Three invasive (peacock bass Cichla piquiti,

Gill ectoparasite assemblages of two non-native Cichla populations (Perciformes, Cichlidae) in Brazilian reservoirs

open access: yes, 2010
The gills of 41 Cichla piquiti and 39 C. kelberi from Itaipu and Lajes reservoirs, respectively, Brazil, were examined to describe the ectoparasite assemblages of these two non-native peacock-bass populations.

Molecular and morphological approaches for species delimitation and hybridization investigations of two Cichla species

open access: yes, 2017
The hybridization is a widely-discussed issue in several studies with fish species. For some authors, hybridization may be related with diversification and speciation of several groups, or also with the extinction of populations or species.

Macroecology of metazoan parasite communities of Cichla kelberi and C. piquiti (Osteichthyes, Cichlidae).

open access: yes, 2012
The macroecology search geographical patterns of distribution and abundance of a species in large-scale, and represents one of the central themes of biogeography. The parasites communities have a fundamental role in the models for studies of biodiversity

A successful case of biological invasion: the fish Cichla piquiti, an Amazonian species introduced into the Pantanal, Brazil

open access: yesBrazilian Journal of Biology
The "tucunaré", Cichla piquiti, an exotic Amazonian fish has become established along the left bank of the Paraguay River in the Pantanal. It was introduced by escaping from culture ponds in the Upper Piquiri River and spread downstream, along the ...
