Organization and Distribution of Repetitive DNA Classes in the Cichla kelberi and Cichla piquiti Genome

open access: yesCYTOLOGIA, 2017
The family Cichlidae is considered a non-Ostariophysi freshwater fish family with diverse and geographical distribution wide in the world; nevertheless there is scarce cytogenetic information for the group. Accordingly, we aim to characterize Cichla kelberi and Cichla piquiti specimens by conventional cytogenetic (Giemsa, Ag-NOR, Banding C) and cyto ...

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]

open access: yesBrazilian 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).

Spar genetic analysis of two invasive species of Cichla (Tucunaré) (Perciformes: Cichlidae) in the Paraná river basin - doi: 10.4025/actascibiolsci.v33i1.4855

open access: yesActa Scientiarum: Biological Sciences, 2011
The introduction of exotic species in lake ecosystems has been greatly highlighted in the literature worldwide. Since introduction may threaten diversity of native fish, the issue turns up to be of paramount importance.

Ultrastructural analysis of spermiogenesis in the neotropical cichlidCichla kelberiKullander & Ferreira, 2006 (Perciformes: Cichlidae)

open access: yesJournal of Applied Ichthyology, 2012
Summary 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 to the nucleus), and consequent nuclear fossa formation.

Analysis of propagule pressure and genetic diversity in the invasibility of a freshwater apex predator: the peacock bass (genus Cichla) [PDF]

open access: yesNeotropical Ichthyology, 2014
An important step in invasive biology is to assess biological variables that could be used to predict invasion success. The study of genetics, evolution, and interactions of invasive and native species in invaded ranges provides a unique opportunity to ...

PESCA EXPERIMENTAL DO TUCUNARÉ (Cichla kelberi KULLANDER & FERREIRA, 2006) INTRODUZIDO EM UM LAGO ARTIFICIAL NO SUDESTE BRASILEIRO

open access: yesRevista Brasileira de Engenharia de Pesca, 2008
Este estudo caracterizou a pesca do tucunaré-amarelo (Cichla kelberi) com iscas artificiais em um lago de Leme-SP. As maiores capturas ocorreram do final do verão ao começo do outono das 9 as 12 horas e das 13 as 15 horas com céu aberto e vento, sendo que as menores capturas ocorreram no inverno.

Organization of Repeated DNA Elements in the Genome of the Cichlid Fish <i>Cichla kelberi</i> and Its Contributions to the Knowledge of Fish Genomes

open access: yesCytogenetic 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) <i>Tc1</i>, <i>

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

open access: yes, 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.
