A genomic march of the penguins
It’s undeniable that penguins are a marine representative of the charismatic megafauna group. I have an affinity for stuff we need microscopes to see, BUT I agree that penguins are cute (just LOOK at these National Geographic photos…they’re even in … Continue reading
Tapping social networks to explore biological systems
Bharat Mishra is wrote this post as part of Dr. Stacy Krueger-Hadfield’s Science Communication course at the University of Alabama at Birmingham. He is currently pursuing his PhD in the lab of Dr. Shahid Mukhtar. He earned an undergraduate degree at … Continue reading

The Molecular Ecologist Podcast: #StudentSciComm, diversity within an algae bloom, the origins of a vital mutualism, and population genetics in continuous space
A new episode of The Molecular Ecologist Podcast is now out on Anchor.fm. The Molecular Ecologist Podcast made it to a second episode! Thanks for listening to our first one, and for all the positive comments. In addition to our “home” … Continue reading
For population genetics, continuous space might be the final frontier
My first exposure to this issue was probably reading Whitlock and McCauley’s 1999 review of the tricky relationship between pairwise genetic differentiation and actual migration rates. Classic theory by none other than Sewall Wright related the differentiation index FST to … Continue reading
The genomic & physiological basis of high altitude adaptation in North American deer mice
In biology, there are many ways to solve evolutionary ‘challenges’ so it always amazes me when organisms solve them in similar ways. And I love a good paper that adds to our attempts to dissect multi-trait adaptations. Recently, Schweizer et … Continue reading
Are population genomic scans for locally adapted loci too successful?
Last Friday, Molecular Ecology released an interesting new systematic review online ahead of print. Colin Ahrens and coauthors at a number of Australian research institutions compiled results from 66 papers reporting tests for locally adapted loci based on either FST … Continue reading

The genomic architecture of ecological speciation
Speciation reshapes the ways genetic diversity is distributed in the genome — it’s been said that the establishment of reproductive isolation is essentially the evolution of genome-wide linkage disequilibrium. The “genomic islands of speciation” model of ecological isolation imagines genome-wide … Continue reading
