Description: The relationship between phenotype and fitness can be visualized as a rugged landscape. Multiple fitness peaks on this landscape are predicted to drive early bursts of niche diversification during adaptive radiation. We measured the adaptive landscape in a nascent adaptive radiation of Cyprinodon pupfishes endemic to San Salvador Island, Bahamas, and found multiple coexisting high-fitness regions driven by increased competition at high densities, supporting the early burst model. Hybrids resembling the generalist phenotype were isolated on a local fitness peak separated by a valley from a higher-fitness region corresponding to trophic specialization. This complex landscape could explain both the rarity of specialists across many similar environments due to stabilizing selection on generalists and the rapid morphological diversification rate of specialists due to their higher fitness.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Martin, Christopher H -- Wainwright, Peter C -- New York, N.Y. -- Science. 2013 Jan 11;339(6116):208-11. doi: 10.1126/science.1227710.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Evolution and Ecology and Center for Population Biology, University of California, One Shields Avenue, Davis, CA, USA. chmartin@ucdavis.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23307743" target="_blank"〉PubMed〈/a〉

Description: Evolutionary innovations, traits that give species access to previously unoccupied niches, may promote speciation and adaptive radiation. Here, we show that such innovations can also result in competitive inferiority and extinction. We present evidence that the modified pharyngeal jaws of cichlid fishes and several marine fish lineages, a classic example of evolutionary innovation, are not universally beneficial. A large-scale analysis of dietary evolution across marine fish lineages reveals that the innovation compromises access to energy-rich predator niches. We show that this competitive inferiority shaped the adaptive radiation of cichlids in Lake Tanganyika and played a pivotal and previously unrecognized role in the mass extinction of cichlid fishes in Lake Victoria after Nile perch invasion.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉McGee, Matthew D -- Borstein, Samuel R -- Neches, Russell Y -- Buescher, Heinz H -- Seehausen, Ole -- Wainwright, Peter C -- New York, N.Y. -- Science. 2015 Nov 27;350(6264):1077-9. doi: 10.1126/science.aab0800.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Evolution and Ecology and Center for Population Biology, University of California, Davis, CA 95616, USA.

Description: Ray-finned fishes make up half of all living vertebrate species. Nearly all ray-finned fishes are teleosts, which include most commercially important fish species, several model organisms for genomics and developmental biology, and the dominant component of marine and freshwater vertebrate faunas. Despite the economic and scientific importance of ray-finned fishes,...

Description: Spiny-rayed fishes, or acanthomorphs, comprise nearly one-third of all living vertebrates. Despite their dominant role in aquatic ecosystems, the evolutionary history and tempo of acanthomorph diversification is poorly understood. We investigate the pattern of lineage diversification in acanthomorphs by using a well-resolved time-calibrated phylogeny inferred from a nuclear gene supermatrix...
