Found in translation: The evolutionary history of RNA viruses in vertebrates

I have to admit, viruses aren’t normally my thing, but this is pretty darn cool. In a study out by Shi and colleagues this week, researchers identified 214 new viruses that, as the authors so succinctly state, reveal “diverse virus-host … Continue reading

The secret life of invaders

So I have this pet theory. And damn if the evidence doesn’t seem to be piling up. Am I living in the bubble of my own google alerts? Possibly. I’m an evolutionary ecologist and invasion biologist, and (surprise!) my pet … Continue reading

Oh my ploidy … diploids evolve more slowly than haploids?

It’s been an embarrassingly long time since I last sat at my keyboard in a TME capacity (#NewPI chat doesn’t really count)! One year ago today, to be exact (writing this on 28 March, for publication on 29 March). Thus, … Continue reading

Major new microbial groups expand diversity and alter our understanding of the tree of life

I still believe in revolutions. And sometimes they just happen, almost unnoticed. One such revolution happened on a boring 11th of April 2016 when Laura Hug et al. published their new tree of life in the journal of Nature Microbiology. … Continue reading

Are population genomic scans for locally adapted loci too successful?

Last Friday, Molecular Ecology released an interesting new systematic review online ahead of print. Colin Ahrens and coauthors at a number of Australian research institutions compiled results from 66 papers reporting tests for locally adapted loci based on either FST … Continue reading

Genomic signatures of ancient rendezvous and separation in elephant evolution

Evidence from various levels of the tree of life is showing that we’ve been picturing ancient encounters between related species all wrong and admixture events are probably more common than expected. Even rendezvous among primates, caniforms, and majestic proboscideans often … Continue reading

What’s in a name? A review of cryptic species and species concepts

It is a contentious can of worms. Species concepts are both essential to understand and at the same time incredibly difficult to define. Species names allow us to discuss fundamental units of biodiversity in any ecosystem and study genome evolution, … Continue reading

Exploring the genomic diversity of tubeworm endosymbionts

Tubeworms are cool. (To be read only in your best (eleventh) Doctor Who voice). Although, depending on how close they are to a hydrothermal vent, they might be more on the hot side….Regardless, if you’re on the fence about how … Continue reading

Retrieving a million sequences and avoiding primer bias, a new method that might have it all

We have come a long way since the early days when sequencing was a breakthrough method initially used to identify uncultured microbes from the environment. It is now been almost three decades, in fact, since the first microbial 16S rRNA … Continue reading

Climate change and genomic vulnerability

As the world burns and we barrel heedlessly into an ever-smaller and uglier future, predicting how species will respond to climate change will be critical for conservation planning. Intuition suggests most organisms will shift their ranges up in latitude or … Continue reading
