Dishing out Art: “Soiling” our microbiology curriculum

Sarah Adkins wrote this post as a final project for Stacy Krueger-Hadfield’s Science Communication course at the University of Alabama at Birmingham. She is a MS student working with Dr. Jeffrey Morris at UAB. They are looking at how microbes (i.e., phytoplankton and E. … Continue reading

For these birds, isolation-by-distance is (almost) all in the family

Isolation by distance is one of the most fundamental processes of molecular ecology. In any finite population, the frequency of a genetic variant will change from generation to generation due to random sampling effects, which we call genetic drift. In … 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

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
