About Ethan Linck

I'm a Ph.D. Candidate at the Department of Biology and the Burke Museum of Natural History, University of Washington, Seattle. My research uses museum specimens and genomic data to analyze and archive avian biodiversity and evolution, particularly in western North America and Melanesia.

Handling microbial contamination in NGS data

Until recently, I had given little thought to the potential for unwanted microbial contamination in high throughput sequence data. I suspect that if you’re a molecular ecologist who doesn’t primarily study microbes or work with ancient DNA, you’re in a … Continue reading

A Primer on the Great BAMM Controversy

Update, 26 August 2016, 2:30PM. A number of readers brought my attention to a series of blog posts by Moore et al. responding to Rabosky’s rebuttal of their published critique of BAMM. I’ve included links to the posts and summarized their … Continue reading

Molecular Inversion Probes: phylogenomics without the excess?

The onset of the phylogenomic era has revolutionized molecular ecology and systematics, helping resolve relationships throughout the tree of life that have long eluded researchers working with only a handful of loci and morphological data. Phylogenetic studies of nonmodel organisms … Continue reading

Mitogenomes from extinct New Zealand wrens shed light on the oldest songbird lineage

The order Passeriformes, commonly known as “perching birds” or “songbirds,” contains over half of all known avian species. Sister to all other Passeriformes are the acanthisittid wrens, a small and enigmatic family of New Zealand endemics. Though their providential phylogenetic … Continue reading

RADseq and missing data: some considerations

Unlike Sanger sequencing, where loci are directly targeted for each individual and sequencing errors are relatively rare, massively multilocus datasets from next generation sequencing platforms are characterized by large amounts of missing data. This is particularly true for restriction digest … Continue reading

hyRAD and museum genomics

While the RAPTURE may have arrived, the development of novel restriction digest-based library prepartation techniques — and portmanteaus — continues unabated. In a paper published in PLoS ONE last month (and previously available as a preprint on bioRxiv), Tomasz Suchan … Continue reading
