Frequency-Dependent Selection Predicts Patterns of Radiations and Biodiversity

Carlos J. Melián, David Alonso, Diego P. Vázquez, James Regetz, Stefano Allesina, Sander van Doorn
2010 PLoS Computational Biology  
Negative frequency-dependent selection predicts well both the declining speciation rate found in cichlid fish and explains their species richness.  ...  Here we show that the temporal trend in the speciation rate can also be explained by frequency-dependent selection. We construct a frequency-dependent and DNA sequence-based model of speciation.  ...  Acknowledgments We thank Andrew Allen, John Alroy, Geoff Conner Newlan, Jonathan Davies, Michael Kopp and Jai Ranganathan for useful comments on the development of the present study.  ...

Frequency-dependent selection predicts patterns of radiations and biodiversity

Carlos Melian, David Alonso, Diego Vazquez, James Regetz, Stefano Allesina
2009 Nature Precedings  
Using negative frequency dependent selection, our model both predicts the declining speciation rate found in cichlid fish and explains their species richness.  ...  We used a frequency-dependent and DNA sequence-based model of populations and genetic-distance-based speciation, in the absence of adaptation to ecological niches.  ...  To explore the tempo of speciation and its implications for biodiversity patterns, we generated a second model with nega-tive frequency dependent selection.  ...

Speciation and the neutral theory of biodiversity

Michael Kopp
2010 Bioessays  
The neutral theory of biodiversity purports that patterns in the distribution and abundance of species do not depend on adaptive differences between species (i.e. niche differentiation), but solely on  ...  In this framework, the ultimate driver of biodiversity is speciation.  ...  the problems of the earlier approaches, while confirming the general ability of neutral theory to predict empirical patterns of biodiversity.  ...

Temporal niche promotes biodiversity during adaptive radiation

Jiaqi Tan, Colleen K. Kelly, Lin Jiang
2013 Nature Communications  
However, only in communities with temporal niches, which promote frequency-dependent selection and the positive growth of new mutants, is the accumulated phenotypic diversity able to persist.  ...  Understanding mechanisms underlying the origin and maintenance of biodiversity is a central goal of modern ecological and evolutionary research.  ...  DEB-1120281 and DEB-1257858 to L.J.; and partially DEB-0713866 to C.K.K. during the initiation of this research).  ...

ECOLOGY: Untangling an Entangled Bank

D. Storch
2005 Science  
His model predicts a variety of patterns in the spatial distribution and abundance of plant species just on the basis of the frequency distribution of total species abundance and a simple probability rule  ...  The continuing responses to selection, therefore, are not likely to be due mainly to continuing tiny changes in gene frequency predicted by the infinitesimal model; instead they may be due to the fixation  ...

The Paradox Behind the Pattern of Rapid Adaptive Radiation: How Can the Speciation Process Sustain Itself Through an Early Burst?

Christopher H. Martin, Emilie J. Richards
2019 Annual Review of Ecology, Evolution and Systematics  
We propose new questions and predictions connecting microevolutionary processes to macroevolutionary patterns through the study of rapid radiations.  ...  The paradox is that the hallmark rapid burst pattern of adaptive radiation is contradicted by most speciation models, which predict continuously decelerating diversification and niche subdivision.  ...  Servedio, and D. Matute for their insightful comments on this manuscript and A. Hendry for discussion. This work was funded in part by an NSF DEB CAREER Award 1749764 to CHM.  ...
