Biological Invasions, 2010
Prey naivete is proposed as one of the main reasons behind species extinctions attributed to invasive predators. This study examined whether the naivete hypothesis could explain extinctions after the introduction of peacock bass (Cichla kelberi) in Parana River, Brazil.

Ethnobiology and Conservation, 2021
Ethnoichthyology has been used to understand how humans perceive environmental changes, including species introductions. In Rio de Janeiro State, southeastern Brazil, fishers introduced juveniles of peacock bass Cichla kelberi in the Juturnaíba Reservoir in the 1990’s.

Journal of Fish Biology, 2017
The first record of pughead deformity in a Neotropical freshwater fish not raised in captivity is provided, based on an adult male of Cichla kelberi introduced into an estuary of Rio de Janeiro State, south‐eastern Brazil. A general biological characterization of the specimen is provided and aspects of its aberrant anatomy are described.

Summary To evaluate the reproductive cycle and fecundity of tucunare´ (Cichla kelberi Kullander & Ferreira, 2006), 697 specimens were captured in Tres Marias Reservoir, Sao Francisco River, Brazil during 1994-1995 and 2005-2006. Reproductive activity was recorded throughout the sampling periods, with females exhibiting asynchronous oocyte development ...

Cytogenetic and genome research, 2009
Repeated DNA elements have been extensively applied as physical chromosome markers in comparative studies for the identification of chromosomal rearrangements, the identification of sex chromosomes, chromosome evolution analysis and applied genetics. Here, we report the characterization of the transposable elements (TE) Tc1, Rex1, Rex3 and Rex6 and a ...

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. Este estudo analisou 76 exemplares capturados no Rio Preguiças, próximo ao Parque Nacional dos Lençóis Maranhenses, visando avaliar o índice ...
