PIMS/Shell Lunchbox Lecture: Adaptive Diversification And Evolutionary Dynamics In High-Dimensional Phenotype Spaces

  • Date: 10/09/2014

Michael Doebeli, University of British Columbia, Departments of Zoology and Mathematics




Michael Doebeli is a specialist in the origin of biological diversity and has pioneered the study of speciation through the approach of mathematical biology. He was the co-author on one of the most widely cited speciation papers ever, "On the Origin of Species by Sympathetic Speciation," in Nature 1999, and is engaged in integrating his work on species diversification to develop an evolutionary understanding of cooperation.

Dr. Doebeli received his MA and PhD in Mathematics from the University of Basel, Switzerland with a special emphasis on dynamical systems in zoology. Since joining UBC as an Assistant Professor in 1999, becoming Professor in 2007, Dr. Doebeli has taught advanced courses in Ecology and Mathematical Biology. He is past director of the Integrated Sciences Program in the Faculty of Science. In addition to his notable publication history, his work has been honoured with such national awards as the NSERC Steacie Fellowship, the UBC Charles S. McDowell Award for Excellence in Research and a UBC Killam Memorial Fellowship.

Adaptive Diversification And Evolutionary Dynamics In High-Dimensional Phenotype Spaces


It is typically used to study evolutionary scenarios in low-dimensional phenotype spaces, such as the important phenomenon of evolutionary branching (adaptive diversification). I will briefly recall the basic theory of evolutionary branching and present a well-studied empirical example. Because birth and death rates of individuals are likely to be determined by many different phenotypic properties, it is important to consider evolutionary dynamics in high-dimensional phenotype spaces. I will present some results about evolutionary branching in high-dimensional phenotype spaces, as well as results about more general types of non-equilibrium evolutionary dynamics, such as chaos. Finally, I will compare the deterministic adaptive dynamics in high-dimensional phenotype spaces to individual-based simulations of the underlying stochastic birth-death process.
