Comparative cytogenetic of six species of Amazonian Peacock bass (Cichla, Cichlinae): intrachromosomal variations and genetic introgression among sympatric species [PDF]

Comparative Cytogenetics, 2020
Cytogenetic data for the genus Cichla Bloch et Schneider, 1801 are still very limited, with only four karyotype descriptions to date. The sum of the available cytogenetic information for Cichla species, points to a maintenance of the diploid number of 48

Genetic diversity in Cichla piquiti and cross-amplification for Cichla kelberi in the Serra da Mesa reservoir, Goiás, Brazil

Acta Scientiarum: Biological Sciences, 2022
Species Cichla piquiti and Cichla kelberi are found in the Serra da Mesa reservoir, Goiás and are sedentary with diurnal habits. This study aimed to evaluate the magnitude and distribution of genetic variability in subpopulations of C.

Changes in ecosystem functions generated by fish populations after the introduction of a non-native predator (Cichla kelberi) (Perciformes: Cichlidae)

Neotropical Ichthyology, 2021
The introduction of non-native predators is a matter of great concern, but their impacts on ecosystem functions remain poorly understood. We investigated how changes in fish diversity following the invasion of Cichla kelberi affected ecosystem functions ...

Impact assessment of the introduction of Cichla kelberi in a large Neotropical reservoir and its lateral lagoons (Upper Paraná River Basin, Brazil)

Brazilian Journal of Biology, 2015
This study aimed to understand how the introduction of Cichla kelberi in Rosana Reservoir (Paranapanema River) affected the native ichthyofauna. Data on the structure of the small fish fauna assemblage were obtained before and after the introduction of ...

Coexistence of endemic peacock basses (Cichla) in a Neotropical reservoir (Cichlidae: Cichliformes) [PDF]

Neotropical Ichthyology, 2022
Peacock basses (genus Cichla) are predatory fish widely distributed across the Amazon, where two or more species normally coexist in a same drainage. The mechanisms that allow coexistence remain poorly understood, although these species share a number of

Genetic characterization of native and introduced populations of the neotropical cichlid genus Cichla in Brazil [PDF]

Genetics and Molecular Biology, 2009
A molecular phylogenetic analysis based on mitochondrial 16S ribosomal DNA and Control Region sequences from native and introduced populations was undertaken, in order to characterize the introduction of Cichla (peacock bass or tucunaré) species in ...

Seasonal and ontogenetic variations in the diet of Cichla kelberi Kullander and Ferreira, 2006 introduced in an artificial lake in southeastern Brazil

Brazilian Journal of Biology, 2010
The diet of Cichla kelberi introduced in an artificial lake in Leme-SP was predominantly composed of common fish species (Oreochromis niloticus and C. kelberi). In the spring and summer, the most consumed item was O. niloticus.
