Genome-wide protein phylogenies for four African cichlid species
BMC Evolutionary Biology, 2018 Background The thousands of species of closely related cichlid fishes in the great lakes of East Africa are a powerful model for understanding speciation and the genetic basis of trait variation.

Altering an extended phenotype reduces intraspecific male aggression and can maintain diversity in cichlid fish [PDF]
, 2013 Reduced male aggression towards different phenotypes generating negative frequency-dependent intrasexual selection has been suggested as a mechanism to facilitate the invasion and maintenance of novel phenotypes in a population.

On the measurement of ecological novelty: scale-eating pupfish are separated by 168 my from other scale-eating fishes. [PDF]
, 2013 The colonization of new adaptive zones is widely recognized as one of the hallmarks of adaptive radiation. However, the adoption of novel resources during this process is rarely distinguished from phenotypic change because morphology is a common proxy ...

Effects of different sampling intervals on apparent protein and energy digestibility of common feed ingredients by juvenile oscar fish (Astronotus ocellatus)=Diferentes intervalos de coleta na determinação da digestibilidade aparente da proteína e da energia de ingredientes comuns para o apaiari (Astronotus ocellatus) [PDF]
Acta Scientiarum: Animal Sciences, 2012 This study evaluated the apparent protein and energy digestibility of common feed ingredients (soybean meal, fish meal, wheat meal and corn) by juvenile oscars using two different sampling intervals (30 min. and 12h).

Genome editing in East African cichlids and tilapias: state-of-the-art and future directions
Open Biology, 2023 African cichlid fishes of the Cichlidae family are a group of teleosts important for aquaculture and research. A thriving research community is particularly interested in the cichlid radiations of the East African Great Lakes. One key goal is to pinpoint

Foraging environment determines the genetic architecture and evolutionary potential of trophic morphology in cichlid fishes [PDF]
, 2016 Phenotypic plasticity allows organisms to change their phenotype in response to shifts in the environment. While a central topic in current discussions of evolutionary potential, a comprehensive understanding of the genetic underpinnings of plasticity is

Hybridisation generates a hopeful monster: a hermaphroditic selfing cichlid [PDF]
, 2016 Compared to other phylogenetic groups, self-fertilization (selfing) is exceedingly rare in vertebrates and is known to occur only in one small clade of fishes.
