Scientific Reports, 2021 Direct tests of gene function have historically been performed in a limited number of model organisms. The CRISPR/Cas system is species-agnostic, offering the ability to manipulate genes in a range of models, enabling insights into evolution, development,

Ecology and Evolution, 2022 Cichlid fishes of the tribe Tropheini are a striking case of adaptive radiation, exemplifying multiple trophic transitions between herbivory and carnivory occurring in sympatry with other established cichlid lineages. Tropheini evolved highly specialized

Ecology and Evolution, 2021 Cichlids inhabiting the Great Lakes of Africa have radiated extremely rapidly, with Lake Malaŵi harboring some 850 species. This rapid radiation may be linked to the diversity in behaviors, sexual selection, and phenotypic plasticity.

Exotic asphyxiation: interactions between invasive species and hypoxia
Biological Reviews, Volume 98, Issue 1, Page 150-167, February 2023., 2023 ABSTRACT Non‐indigenous species (NIS) and hypoxia (<2 mg O2 l−1) can disturb and restructure aquatic communities. Both are heavily influenced by human activities and are intensifying with global change. As these disturbances increase, understanding how they interact to affect native species and systems is essential.

The Evolutionary Dynamics of the Mitochondrial tRNA in the Cichlid Fish Family
Biology, 2022 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.

Modular genetic control of social status in a cichlid fish
Proceedings of the National Academy of Sciences of the United States of America, 2020 Significance Social rank along a hierarchy determines physiological state and behavioral performance. A ubiquitous feature of social hierarchies is the communication of rank through nonphysical signaling systems (e.g., coloration) and aggression, traits ...

Evolution, Volume 76, Issue 12, Page 3041-3053, December 2022., 2022 Abstract Rensch's rule suggests that sexual size dimorphism (SSD) increases with species size when males are the larger sex, whereas it decreases when females are the larger sex. However, the process responsible for this pattern remains obscure. SSD can result from sexual selection, such as intrasexual competition for access to mates, or from natural ...

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.
