Growth and mortality of Cichla spp. (Perciformes, Cichlidae) introduced in Volta Grande Reservoir (Grande River) and in a small artificial lake in Southeastern Brazil [PDF]

Brazilian Journal of Biology, 2010
The growth and mortality parameters were estimated through the analysis of length frequency distribution for species of Cichla spp. introduced into a lake in Leme (SP), and in Volta Grande reservoir (SP-MG).

Invasive non-native species of fish in upper Paraná river Basin, Brazil: variations of caloric content in Cichla kelberi

Neotropical Ichthyology, 2012
The allocation of assimilated energy may be influenced by seasonal changes, growth, and reproductive cycle of fish, food consumption and environmental conditions.

Rapid morphological change in multiple cichlid ecotypes following the damming of a major clearwater river in Brazil. [PDF]

Evol Appl, 2020
Abstract While anthropogenic disturbances can have damaging effects on biodiversity, they also offer an opportunity to understand how species adapt to new environments and may even provide insights into the earliest stages of evolutionary diversification. With these topics in mind, we explored the morphological changes that have occurred across several

Prospecção reprodutiva e energética do tucunaré-amarelo Cichla kelberi cichliformes: cichlidae em ambiente natural na bacia adjacente ao Parque Nacional dos Lençóis Maranhenses, Nordeste do Brasil

Caderno Pedagógico
O tucunaré-amarelo (Cichla kelberi) tem sido introduzido em reservatórios brasileiros, porém ainda há poucas informações sobre sua biologia reprodutiva, maturação gonadal, aspectos energéticos e perfil lipídico.

Linking rivers, mixing faunas: How artificial connectivity between the Middle and Upper Paraná River basins shapes fish diversity in a tributary of the Itaipu Reservoir, Brazil. [PDF]

J Fish Biol
Abstract This work aimed to investigate the distribution and occurrence of fish species along the São Francisco Falso Braço Norte (SFFBN) River basin, a tributary of the Middle Paraná River basin now artificially connected to the Upper Paraná ecoregion, to evaluate how such connectivity may affect the biogeographic distribution and regional composition

Machine learning models accurately predict clades of proteocephalidean tapeworms (Onchoproteocephalidea) based on host and biogeographical data. [PDF]

Cladistics
Abstract Proteocephalids are a cosmopolitan and diverse group of tapeworms (Cestoda) that have colonized vertebrate hosts in freshwater and terrestrial environments. Despite the ubiquity of the group, key macroevolutionary processes that have driven the group's evolution have yet to be identified.

Reduced genetic diversity and the success of the invasive peacock bass (Cichliformes: Cichlidae)

Brazilian Journal of Biology, 2021
Several species of Cichla successfully colonized lakes and reservoirs of Brazil, since the 1960’s, causing serious damage to local wildlife. In this study, 135 peacock bass were collected in a reservoir complex in order to identify if they represented a ...

Biologia e ecologia comparativas de Cichla Kelberi e Cichla Piquiti (Cichliformes, Cichlidae) no reservatório da UHE de Lajeado, rio Tocantins [PDF]

, 2021
n the Tocantins River Basin there are two species of the genus Cichla that live in sympatry, Cichla kelberi and C. piquiti. Cichla piquiti is more abundant than its congener C. kelberi. The aim of the study was to compare the ecology and biology of C.
