Abstract
This is the second special issue on cichlid evolution hosted by the International Journal of Evolutionary Biology. Once more, we are overwhelmed by the vivid responses to our call for contributions, and thank the authors for their great work. The thirteen papers in this issue, including two reviews, span geographically from Africa to South America and address a wide variety of evolutionary topics including speciation and hybridization, phenotype evolution, and reproductive behaviour. Papers are summarized below in the order in which they appear in this special issue.
Highlights
Their review links data on cichlid diversity with the highly variable geological and paleoclimatic history of East Africa and serves as an important reference for the impact of geological, paleoecological, and paleoclimatic factors on biogeography
Received 9 August 2012; Accepted 9 August 2012. This is the second special issue on cichlid evolution hosted by the International Journal of Evolutionary Biology
The role of spatial environmental variation in driving natural selection on these sensory traits has become increasingly appreciated, and it has been proposed that such “sensory drive” may even have promoted speciation through sexual selection in the Lake Victoria cichlid radiation
Summary
Their review links data on cichlid diversity with the highly variable geological and paleoclimatic history of East Africa and serves as an important reference for the impact of geological, paleoecological, and paleoclimatic factors on biogeography. This is the second special issue on cichlid evolution hosted by the International Journal of Evolutionary Biology. D. Danley et al provide an up-to-date synthesis of the geologic history and paleoclimate of the East African Great Lakes (and surrounding water bodies) and the evolution of the region’s endemic cichlid species assemblages.
