Ancient hybridization fuels rapid cichlid fish adaptive radiations
Understanding why some evolutionary lineages generate exceptionally high species diversity is an important goal in evolutionary biology. Haplochromine cichlid fishes of Africa's Lake Victoria region encompass >700 diverse species that all evolved in the last 150,000 years. How this 'Lake Victoria Region Superflock' could evolve on such rapid timescales is an enduring question. Here, we demonstr...
متن کاملConvergent Evolution within an Adaptive Radiation of Cichlid Fishes
The recurrent evolution of convergent forms is a widespread phenomenon in adaptive radiations (e.g., [1-9]). For example, similar ecotypes of anoles lizards have evolved on different islands of the Caribbean, benthic-limnetic species pairs of stickleback fish emerged repeatedly in postglacial lakes, equivalent sets of spider ecomorphs have arisen on Hawaiian islands, and a whole set of converge...
متن کاملGeometric morphometric analyses provide evidence for the adaptive character of the Tanganyikan cichlid fish radiations.
The cichlids of East Africa are renowned as one of the most spectacular examples of adaptive radiation. They provide a unique opportunity to investigate the relationships between ecology, morphological diversity, and phylogeny in producing such remarkable diversity. Nevertheless, the parameters of the adaptive radiations of these fish have not been satisfactorily quantified yet. Lake Tanganyika...
متن کاملCirculating Levels of Agouti-Related Peptide in Endometrial Cancer Survivors
Background Recently, it has been reported that central administration of agouti-related peptide (AgRP) might have protective effect against cachexia development in tumor-bearing mice. In this study, we determined whether the disease-free endometrial cancer survivors present with different plasma AgRP levels than controls and whether there was an association with the duration of the disease-free...
متن کاملMulti-Agent Simulations of Evolution and Speciation in Cichlid Fish
An agent-based simulation has been built to model speciation in cichlid fishes in the Great Lakes of Africa. A real natural system has been chosen as the target of simulation, rather than a generalised system. This focusses research towards open problems in cichlid biology, and provides a library of field research to drive the design and parametrisation of the simulation. Visualisations of the ...
