What we're reading: Genomic selection scans, local adaptation, and the grass is actually pretty green on this side of the publishing fence
In the journals Cadzow M, J Boocock, HT Nguyen, P Wilcox, TR Merriman and MA Black. 2014. A bioinformatics workflow for detecting signatures of selection in genomic data. Front. Genet. 5:293. doi: 10.3389/fgene.2014.00293. Here we describe a basic workflow, constructed … Continue reading

The #IcedBudgetChallenge: Tell Congress to thaw out funding for NSF and NIH!
So a friend nominated me in this viral scheme to raise funds for ALS research, about which you may have heard lately. I’m all in favor of finding a cure for ALS—my grandfather died of it—but I’m also pretty skeptical … Continue reading

You can evolve there from here. And from here. And here …
If evolutionary history somehow reverted back to the “warm little pond” in which life began, and started over from almost-scratch, would the re-diversification of life end up, four billion years later, pretty much as we see it today? I think … Continue reading

What we're reading: Selection for heterozygosity in threatened seals, and testing Fst outlier tests
In the journals Forcada J and Hoffman JI. 2014. Climate change selects for heterozygosity in a declining fur seal population. Nature. 511:462–465. doi: 10.1038/nature13542. Variation in SAM [Southern Annular Mode of the Antarctic atmosphere] significantly affects most of the life … Continue reading

What we're reading: Estimating linkage in resequencing data, genomics of host-parasite coevolution, and scientific work-life balance
In the journals Maruki, T., and M. Lynch. 2014. Genome-wide estimation of linkage disequilibrium from population-level high-throughput sequencing data. Genetics 197:1303–1313. doi: 10.1534/genetics.114.165514. … we developed a maximum-likelihood estimator of linkage disequilibrium for use with error-prone sampling data. Computer simulations … Continue reading

How many genes does it take to make a new species?
Three-spined sticklebacks are speciation machines. When retreating glaciers exposed lakes and rivers around the coasts of northern North America and Eurasia, these armor-plated little fish colonized the new freshwater habitats from the ocean, and adapted to the threats and resources … Continue reading
