Biological Invasions, 2009
In South America, the introduction of peacock-bass (Cichla), a voracious predator fish, has been an underestimated threat for native fish communities. Although this predator is widespread in many reservoirs, few studies have explored its impact on biodiversity.

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.

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 ...

Journal of Applied Ichthyology, 2009
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 ...
