How much wood would a termite chuck…if it was missing its microbial symbionts

Termites get a pretty bad rap, probably because we think of our houses disintegrating when they move in. Ironically, we have a lot to learn from these critters, and their mounds have served as an inspiration for modern architecture. Either … Continue reading

The seeds of speciation

You don’t have to get very far into an evolution textbook before you bump into Darwin’s finches, the birds descended from South American finches that colonized the Galapagos Islands and “radiated” into an array of different species, each with a … Continue reading

Diving into chilly California waters, understanding genomic differentiation and the role of gene transfer in marine cyanophages

At this point, it’s clear: microbes are everywhere, there are a lot of them, and they are important. In fact, they are more abundant, more diverse and older than any other organism we have on this planet. In particular, cyanobacteria … Continue reading

A Comparative View of Comparative Phylogeography

A recent issue of PNAS includes papers from a Sackler Colloquium on comparative phylogeography. As stated by the organizers, a major purpose of that gathering “was to bring together leading scientists to address the current state of phylogeography as the … Continue reading

What’s all the buzz about? Bees got microbiomes too!

So I know we are all blabbing about the human microbiome, who isn’t fascinated by the impressive roles tiny microbes have in our lives!? Trying to unravel what exactly our microbial communities do for us, and how they relate to … Continue reading

A new (quantitative!) method for comparative phylogeography

Comparative phylogeographic studies usually involve a) documenting a phylogeographic pattern and b) recognizing that the same pattern is congruent in multiple species. But what if species histories are only sortof congruent? Perhaps they share one major splitting event but not later … Continue reading

One of these things is not like the other……

While we know that bacteria are pretty scandalous with their DNA, not minding horizontal gene transfer (HGT) and such (which can be pretty confounding when trying to discuss species concepts), and although it’s clear that this kind of genetic material … Continue reading

When times are good or bad, happy or sad, viral quasispecies like to stay together

We’ve known for a long time that symbioses are important across all walks of life. Clownfish and sea anemones are obligate symbionts, and bacteria found in legume root nodules help fix nitrogen. In a nice review published recently in Evolutionary … Continue reading

A race to the bottom with a new card from the coevolutionary deck

I’m a sucker for a clever, amusing title, though I’ve recently read that amusing titles are cited less (see here). Alas, maybe a well placed metaphor can enliven a manuscript and also not get lost in a citation-less abyss? In basic … Continue reading

Pre-adapted algal ancestors colonized land

The colonization of land by plants 450 Mya marked a major transition on Earth and was one of the critical events that led to the emergence of extant terrestrial ecosystems. Chief among the challenges the terrestrial environment presented for these … Continue reading
