A population genetic R-evolution
Uphill, both ways, in the snow, without shoes … quite apt when thinking of the dark days, in the not too distant past, in which a separate input file was needed for each popgen analysis in order to use a … Continue reading

Linking gene expression and phenotype in an emerging model organism
Last week in his post “Transcriptomics in the wild (populations),” TME contributor Noah Snyder-Mackler focused on a recent paper by Alvarez et al. that reviews the last decade of transcriptomic research including the goal of linking gene expression and phenotype. Researchers today routinely collect transcriptomic data for non-model … Continue reading

Increase your broader impacts with Data Nuggets
This week we have a special guest post by Elizabeth Schultheis, a PhD candidate at Michigan State University and the Kellogg Biological Station, to describe her Data Nuggets project. Previous guest posts have discussed other great projects happening in the … Continue reading
Isolation by environment explains why the grass isn't always greener
Ever since Sewall Wright introduced isolation by distance in 1943, the interplay between genetic differentiation and geographic distance has been a foundational, sometimes frustrating, aspect of population genetics studies. But distance isn’t just distance. The walk to my car isn’t any longer when … Continue reading
The big chief at Molecular Ecology Resources: Interviewing Shawn Narum
What are the most exciting parts of doing science? The first look at results? The sheen of your publication finally in print? That initial foray out into the field? What about the moment you figure out a way to make a … Continue reading

The latest gadget for the molecular ecologist’s toolkit
Designing a sampling scheme to collect an organism of interest for a population genetic/genomic study can be fraught with difficulty. How best to sample? Randomly? Or, along a grid? How many individuals to sample? Thirty? Or, perhaps, the sample size … Continue reading
Bayesian Markov-chain Monte Carlo in population genetics
This is a guest post by Arun Sethuraman, a postdoctoral associate with Jody Hey, studying statistical models for divergence population genetics in the Department of Biology at Temple University. You can also find him on Twitter, and on his short story blog. Prompted by the great response … Continue reading
Crowd-sourcing natural history
What I think of as my first “real” science job was a year I spent in Pittsburgh, interning for the Western Pennsylvania Conservancy. One of my most enjoyable duties was assisting a WPC ecologist on systematic surveys of plant diversity … Continue reading
