12-minute long talk that I gave at CSEE 2013 (http://csee2013.ok.ubc.ca/Home.html). Most of the work is based on a paper that I recently published with Ophélie Ronce and Sylvain Gandon (DOI: 10.1111/jeb.12132, available online at http://onlinelibrary.wiley.com/doi/10.1111/jeb.12132/abstract and the pdf on my personal website).
Adaptation and demography in a heterogeneous environments
1. Quantifying the effects of migration and
mutation on adaptation and demography in
spatially heterogeneous environments.

10. Eco-evolutionary existential questions
cChristopherMarley
Why is there something instead of nothing?
[Population persistence]
Why are things where they are and not
elsewhere? [Species ranges]
Why are there so many/few things?
[Origin and maintenance of diversity. ]
