Hybridization and adaptive radiations

As an iconic system in evolutionary biology, I’ve always been interested in African cichlids and the origins of their diversity1. These cichlids represent an adaptive radiation; they’ve evolved rapidly from a single origin to exploit and speciate into open niches … Continue reading

Highlights from the Standalone Society of Systematic Biologists meeting – part 2

The 2017 standalone meeting of the Society of Systematic Biologists included expert-led debates on major issues in molecular systematics. Didn’t make it to Baton Rouge? Don’t worry – Melissa DeBiasse and I report on some of the main points (and our favorite lightening … Continue reading

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

I do not think it means what you think it means: “relic DNA” can obscure microbial diversity studies

Although microbes are small, they play an important part in both biogeochemical cycles in the ocean as well as on land. However, as they are not so easy to observe by eye, and in many cases can’t be cultured in … Continue reading

When the going gets hot the dinoflagellates (sometimes) get going, how viruses might affect coral symbionts

Corals represent more than meets the eye, they host intricate and interesting communities composed of dinoflagellates (also referred to as zooxanthellae), and a suite of microbes that include bacteria, archaea, fungi, protists, and viruses. One such dinoflagellate that often shares … Continue reading

There are more microbes than meet the eye: exploring the genomic diversity in an aquifer

First: it’s Tuesday, November 8th, 2016 – before you even think about putting your feet up and reading this post, I hope you’ve managed to wrangle yourself one of those highly prized “I voted” stickers. Now, on to more microbial … Continue reading

Gene expression shows how a plant and its mutualists are better together

No living thing is an island, and many of the encounters between living things that happen every day are not antagonistic or even indifferent, but mutually beneficial. Two such mutualisms that could be among the most important on the planet … Continue reading
