What we’re reading: Landscape genomics in Evolution, tracking evolution with more than two alleles, and the value of the selfish gene meme


In the journals

Petren, K. 2013. The evolution of landscape genetics. Evolution 67:3383–5 doi: 10.1111/evo.12278.

Evolutionary landscape genetics is the study of how migration and population structure affects evolutionary processes. As a field it dates back to Sewall Wright and the origin of theoretical population genetics, but empirical tests of adaptive processes of evolution in natural landscapes have been rare. Now, with recent developments in technology, methodology, and modeling tools, we are poised to trace adaptive genetic variation across space and through time.

… allelic-diversity variables are better predictors of long-term adaptation than gene-frequency variables. This observation is also extended to unlinked neutral markers as a result of the information they convey on the demographic population history.

In the news

David Dobbs goes looking for new metaphors in a world of non-Mendelian genetics. But see also; and also.

Want to buy an authorship? Apparently doing that is shockingly direct.

Bad news gets worse: On funding rates for the NIH.
