Dynamic co-evolution of transposable elements and the piRNA pathway in African cichlid fishes [PDF]
Background East African cichlid fishes have diversified in an explosive fashion, but the (epi)genetic basis of the phenotypic diversity of these fishes remains largely unknown.

Evolution of regulatory networks associated with traits under selection in cichlids
Background Seminal studies of vertebrate protein evolution speculated that gene regulatory changes can drive anatomical innovations. However, very little is known about gene regulatory network (GRN) evolution associated with phenotypic effect across ...

Oca2 targeting using CRISPR/Cas9 in the Malawi cichlid Astatotilapia calliptera
Identifying genetic loci underlying trait variation provides insights into the mechanisms of diversification, but demonstrating causality and characterizing the role of genetic loci requires testing candidate gene function, often in non-model species ...

Ergasilus (von Nordmann, 1832) (Ergasilidae) is a species-rich group of parasitic copepods with a wide distribution in freshwater, marine and brackish environments. Up to now, 9 species of Ergasilus are known from cichlid fishes in Africa. In this study,

Natural variation in the number, expression and function of sensory genes in an organism's genome is often tightly linked to different ecological and evolutionary forces. Opsin genes, which code for the first step in visual transduction, are ideal models

The Evolutionary Dynamics of the Mitochondrial tRNA in the Cichlid Fish Family
The mitochondrial transfer RNA genes (tRNAs) attract more attention due to their highly dynamic and rapidly evolving nature. The current study aimed to detect and evaluate the dynamics, characteristic patterns, and variations of mitochondrial tRNAs.

Cichlids and stingrays can add and subtract ‘one’ in the number space from one to five
The numerical understanding of cichlids and stingrays was examined regarding addition and subtraction abilities within the number space of one to five. Experiments were conducted as two-alternative forced-choice experiments, using a delayed matching to ...

Elaboration, development, and installation of the first animal skin bank in Brazil for the treatment of burns and wounds [PDF]
Introduction: The production and distribution of human skin by Brazilian skin banks is insufficient to meet the country's demand, supplying less than 1% of the need for treating burn victims.

Mitochondrial genome annotation and phylogenetic placement of Oreochromis andersonii and O. macrochir among the cichlids of southern Africa. [PDF]
Genetic characterization of southern African cichlids has not received much attention. Here, we describe the mitogenome sequences and phylogenetic positioning of Oreochromis andersonii and O. macrochir among the African cichlids.
