How do Missing Data Impact Phylogenetic Inference with UCEs?

Next-generation sequencing (NGS) has put gobs of sequence data in the hands of molecular biologists, and that data is measurably advancing our prospects for a fully resolved Tree of Life. Nearly simultaneously, however, we have realized that every NGS dataset … 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

What do dolphins, bivalves and algae have in common?

Collaboration as it turns out, between three scientists interested in vertebrates, invertebrates and algae! A few days before we left for Evolution 2016 in Austin, one of my collaborators, Eric Pante, came to Charleston as the final stop in a North American … 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

New World snakes are “mimics until proven otherwise”

Henry Walter Bates spent more than a decade living in the Amazon, having the sort of adventures that inspired generations of naturalists. His most famous and lasting contributions to natural history are his foundational descriptions of mimicry among species. The type … 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

Island-Hopping with an E.I.D.

If you live in the U.S. and feel like Zika virus is getting closer to home, that’s because it is. Although there are no known cases of Zika transmission by natural vectors in the lower 48, experts have stressed that … Continue reading
