BMC Evolutionary Biology, 2019 Background Cichlids are a prime model system in evolutionary research and several of the most prominent examples of adaptive radiations are found in the East African Lakes Tanganyika, Malawi and Victoria, all part of the East African cichlid radiation ...

The root of the East African cichlid radiations [PDF]
BMC Evolutionary Biology, 2009 Background For decades cichlid fishes (Perciformes: Cichlidae) of the East African cichlid radiations (Teleostei: Cichlidae) have served as natural experimental subjects for the study of speciation processes and the search for potential speciation key ...

Frontiers in Microbiology, 2019 Cichlid fishes, with their repeated colonization of lakes and subsequent radiations at different scales of phylogenetic and ecological diversification, offer an excellent model system to understand the factors shaping the host-gut microbiota association ...

Evolutionary divergence of 3’ UTRs in cichlid fishes [PDF]
BMC Genomics, 2018 Post-transcriptional regulation is crucial for the control of eukaryotic gene expression and might contribute to adaptive divergence. The three prime untranslated regions (3’ UTRs), that are located downstream of protein-coding sequences, play important ...

Freshwater hydrozoan blooms alter activity and behaviour of territorial cichlids in Lake Tanganyika [PDF]
Royal Society Open Science, 2019 Blooms of gelatinous zooplankton can represent dramatic environmental perturbations for aquatic ecosystems. Yet, we still know little about how blooms impact fitness-related behaviours of fish caught within their areas of effect, especially for ...

The cichlid oral and pharyngeal jaws are evolutionarily and genetically coupled
Nature Communications, 2021 Evolutionary constraints may significantly bias phenotypic change, while “breaking” from such constraints can lead to expanded ecological opportunity.

Cellular basis of differential endochondral growth in Lake Malawi cichlids
Developmental Dynamics, Volume 251, Issue 12, Page 2001-2014, December 2022., 2022 Abstract Background The shape and size of skeletal elements is determined by embryonic patterning mechanisms as well as localized growth and remodeling during post‐embryonic development. Differential growth between endochondral growth plates underlies many aspects of morphological diversity in tetrapods but has not been investigated in ray‐finned ...

Divergence and introgression among the virilis group of Drosophila
Evolution Letters, Volume 6, Issue 6, Page 537-551, December 2022., 2022 Abstract Speciation with gene flow is now widely regarded as common. However, the frequency of introgression between recently diverged species and the evolutionary consequences of gene flow are still poorly understood. The virilis group of Drosophila contains 12 species that are geographically widespread and show varying levels of prezygotic and ...

The evolution of monogamy in cichlids and marine reef fishes
Frontiers in Ecology and Evolution, 2022 Although several hypotheses have been proposed to explain the emergence of social monogamy, its origin is still intensely debated. Monogamy has many potential drivers, but evolutionary causality among them remains unclear.
