How many markers does it take to make a dataset “genomic”?

A new paper in Ecology Letters by Matthew Fitzpatrick and Stephen Keller proposes to use some a class of statistical methods developed for understanding the distribution of species in different environments to understand the distribution of genetic variants in different … Continue reading

Spontaneous mutations—friend or foe?

The following is a cross-posting from the Stanford CEHG Blog by Ryo (Ryosuke) Kit, a graduate student in Hunter Fraser’s lab at Stanford University. Evolution has conflicting opinions about spontaneous mutations. Spontaneous mutations produce the genetic variation that drives evolution … Continue reading

Scanning the genome for local adaptation

One of the most obvious and important applications of evolutionary genetics is in figuring out whether natural biological communities are going to be able to adapt to global climate change. The projected rate of climate change over then next century … Continue reading

2014 NGS Field Guide: Resistance is Futile (mostly, at least for a while)

This year, to introduce the 2014 update to his Next Generation Sequencing Field Guide—perennially our most-accessed community resource—Travis Glenn has a bit more to say than just what goes in the tables. So here it is as a guest post! … Continue reading

No reference genome? No problem! Demographic inference from genomic data in nonmodel insect populations

This guest article by Martin Sikora is cross-posted from the Computational, Evolutionary and Human Genomics blog at Stanford University. Reconstructing the demographic history of species and populations is one of the major goals of evolutionary genetics. Inferring the timing and … Continue reading

Want to share your code?

In this line of work, we have all encountered tasks that are tedious, time consuming, and repetitive.  (Or if not, maybe give it a bit more time.) When confronted with these situations, people tend to fall into one of two … Continue reading

Phylogeny-aware comparisons of microbial communities – EdgePCA and Squash Clustering

I’m jumping on the bandwagon with a blog post about this new PLoS ONE paper (taking the lead from the man in charge in my lab) because the algorithms are just so exciting: Matsen FA IV, Evans SN. (2013) Edge Principal … Continue reading

Q&A: Yannick Wurm wrangles RADseq to learn why some fire ants bow to more than one queen

Yannick Wurm grew up in Redwood City, California, and his initial plan was to design interfaces for Apple. But he went to university at the Institut National des Sciences Appliquées in Lyon—where, after two years of general engineering courses, the … Continue reading

Next-gen sequencing field guide, 2013 edition

Travis Glenn has updated his Field Guide to Next-Generation Sequencing, originally published in 2011, to account for changes to this almost axiomatically dynamic field. The 2013 update to the Field Guide tables is online here. Previous editions of the tables … Continue reading
