Free to go but required to stay: contrasting views on mitochondrial relationships

Ever since a bacterium found itself mysteriously engulfed in our eukaryotic ancestor, things have been, uh, complicated regarding our two genomes. One is big, one is small. One is circular, one is linear. One is numerous in each cell, the … Continue reading

Artificial connectivity … have we overlooked the native range?

Invasive species are problematic throughout the world’s ecosystems, down even to their very name which incites heated debates. Every month, studies are published that describe the genetic structure and gene flow of non-native species in their introduced ranges. Often, these … Continue reading

Humans, selection, evolution and ecological timescales … a potent cocktail

It’s been awhile since I last was able to write for TME. But, finally, I’ve stolen away some time to write about a recent study in Ecology Letters that I couldn’t put down once I started reading it. Yes, it’s about mating … Continue reading

Still ruffling feathers after all these years: Darwin’s finches and a molecular view of adaptive radiation

One of the many lovely things about molecular ecology is its ability to shine new light on old stories. The well-known case of Darwin’s finches is a classic example of adaptive radiation. These finches demonstrate a clear instance where over time, … Continue reading

Conifer convergence

Convergent local adaptation is typically studied within a species or between closely related species. In these cases, it is perhaps not unexpected to observe parallel evolution due to common genetic variation, constraints, etc. Convergence between species is somewhat less studied, … Continue reading

It’s not the size that counts: teeny tiny SAR11 bacteria play a big role in our oceans

Microbes account for a huge chunk of the diversity on this planet, are essential in all sorts of biogeochemical processes, and we are still figuring out how everything is related. Teeny tiny bacterial cells are abundant both on land as … Continue reading

Visualizing the evolution of bacterial resistance

You have probably already seen this. It’s pretty amazing and beautiful and I watched it more than once (although I won’t say how many times….). If by some chance you didn’t catch this fantastic video, don’t fret, I’m here to … Continue reading
