Totally RAD

Puritz et al. (2014) weigh the pros and cons of, the aptly titled, “RAD fad” in a comment recently published online in Molecular Ecology. They challenge: (1) the assertion that the original RAD protocol minimizes the impact of PCR artifacts … Continue reading

Caught sweeping ‘cross the sea

  The salmon louse Lepeophtheirus salmonis is an ectoparasite linked to declines in wild salmonid populations as well as causing huge economic losses in salmon farms. Previous studies, using a variety of molecular markers, yielded conflicting results ranging from strong … Continue reading

From cats to rats: two studies on domestication and tameness

Anyone who has ever read Charles Darwin is acutely aware of his fascination with domestication – particularly how he fancied fancy pigeons. Darwin drew on his domestication obsession while writing his book, The Variation of Animals and Plants under Domestication, … Continue reading

The forest resounding at rare intervals with the note of … reproductive isolation

Hybrid zones are often used as a window with which to gaze upon the evolutionary process (Barton and Hewitt 1989). With the advent of genomic tools, it is possible to detect the genomic signatures and the architecture underlying reproductive isolation. In … Continue reading

WTF (What’s The Function?)

Jay Shendure’s editorial, “Life after genetics”, points out that we, as geneticists, should shift our focus from variant-finding (e.g., GWAS) to understanding the functional implications of disease-associated variants: “We are in a period of rich discovery in human genetics and genomics. The … Continue reading

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
