A Master Manipulator: How a bacterium tells a plant what to do
Katrina Sahawneh wrote this post as a final project for Stacy Krueger-Hadfield’s Science Communication course at the University of Alabama at Birmingham. Katrina is working on her MS in Biology and her MA in Education. She currently is studying ER stress … Continue reading

Field notes from city streets
I spent this morning in Los Angeles city parks, pulling up clover. This attracted less attention than you might expect. Angelenos are, as a group, not inclined to bother people who aren’t doing anyone else any obvious harm, and honestly … Continue reading

#Evol2017 catch-up — Effects of range expansions on mating system
Two weeks (more about that in a post I’ve written for Wednesday!) after the closing day of the 2017 Evolution Meetings, the Molecular Ecologists have all dispersed from Portland, though some may have left things behind! Still, the conference was so … Continue reading

Relatively rare tropical trees all agree: avoiding the ‘rain of death’ seems like a good call
When you think of a tropical jungle, what’s the first thing that comes to mind? Probably a lush green landscape with trees, vines, flowers, and let’s be real, at least one toucan. Tropical forests are made up of diverse groups … Continue reading
Polyploidy in the era of GBS
Ploidy, dear reader, is something that I think about literally all the time. It impacts every facet of my research from the field to the bench to the stats used to analyze data sets. It’s been simultaneously the greatest and the … 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

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

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

The Genomics of Rapid Adaptation
Phenology (the timing of life cycle events such as growth, breeding, or migration) is among the most sensitive organismal traits to climate and environmental change. In recent years, phenological shifts have been documented in numerous taxa, in traits such as … Continue reading
The not so singular process of hybridization
What, if anything, are hybrids? Zach Gompert and Alex Buerkle ask this question in a special issue in Evolutionary Applications. Hybrids occur when unrelated individuals mate, but how distant do the taxa need to be to constitute a cross? The varied … Continue reading
