Evolutionary dynamics of retrotransposable elements Rex1, Rex3 and Rex6 in neotropical cichlid genomes
(2013-07-18)
Background: Transposable elements (TEs) have the potential to produce broad changes in the genomes of their hosts, acting as a type of evolutionary toolbox and generating a collection of new regulatory and coding sequences. ...

Persistence and stability of cichlid assemblages in neotropical floodplain lagoons
(Springer, 2012-02-01)
In this study, we evaluated how cichlid assemblages are affected by seasonal and interannual variations in water volume in the floodplain lagoons of the Cuiaba River in the Pantanal wetland. Eleven lagoons were sampled in ...
Chromosomal evolution of neotropical cichlids: The role of repetitive DNA sequences in the organization and structure of karyotype
(2013-01-01)
Cichlids are important in the aquaculture and ornamental fish trade and are considered models for evolutionary biology. However, most studies of cichlids have investigated African species, and the South American cichlids ...

From molecule to behavior: Brain aromatase (cyp19a1b) characterization, expression analysis and its relation with social status and male agonistic behavior in a Neotropical cichlid fish
(Academic Press Inc Elsevier Science, 2017-03)
The enzyme aromatase, responsible for the conversion of C19 androgens to C18 estrogens, exists as two paralogue copies in teleost fish: Cyp19a1a mostly expressed in the gonads, referred as gonadal aromatase, and Cyp19a1b, ...
Ultrastructural analysis of spermiogenesis in the neotropical cichlid Cichla kelberi Kullander & Ferreira, 2006 (Perciformes: Cichlidae)
(Wiley-Blackwell, 2012-12-01)
In the Neotropical cichlid Cichla kelberi the spermiogenesis appears to be of the cystic type and is characterized by gradual chromatin condensation in juxtaposed clusters, nuclear rotation (with the flagellum perpendicularly ...
