At the molecular level, there’s more than one way to fly higher

Parallel adaptation is coming into its own lately, as we’re increasingly able to examine the molecular changes underlying similar adaptations in distantly related species. A fundamental prediction of evolutionary theory is that species coping with the same environment should converge … Continue reading

The tarsier’s nuclear genome comes with a bonus mitochodrial genome

This week Nature Communications published a paper presenting a new genome assembly for Tarsius syrichta, the Phillipine tarsier. Tarsiers are the subject of one of the best of Ze Frank’s “True Facts” videos, and they occupy an interesting place in … Continue reading

Building bridges across the chaos

In a new review, Eldon and co-authors (in press) attempt to build a bridge across the chaos of genetic patchiness in the sea. They i) describe the patterns characterized as chaotic genetic patchiness, ii) discuss the potential causes of these patterns and … Continue reading

Is equilibrium out of reach or are there some sneaky bouts of sex?

Reproductive systems impact the evolution of genetic diversity at the population level. Yet, we don’t know a lot about organisms that are partially clonal, despite the large component of biodiversity that dabbles in asexual reproduction to varying degrees. Clonal dynamics are … Continue reading

Phenotypes in Comparative Phylogeography

Earlier this week, The Molecular Ecologist contributor Bryan McLean posted about the current state of comparative phylogeography (Riddle 2016). He listed several exciting directions that comparative phylogeography is heading, including more research that includes trait data. As a followup to … Continue reading

A tale of mammoths and a disappearing lake

A wonderful study revealed a sad story of the St. Paul Island population of woolly mammoths. Using a creative and diverse set of analytical approaches, scientists identified freshwater shortage as the likely cause of their extinction. A cross-disciplinary collaboration of … 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
