Genomics of Hybridization – Part 1

Posted on 21 Jan, 2016 by Arun Sethuraman

In a series of articles, I will discuss recent advances in hybridization genomics – the fundamentals of adaptive introgression, “islands of speciation”, differential gene flow, and linked selection have been discussed in my previous posts (here, here, and also at … Continue reading →

Earthquakes and rapid evolution

Posted on 7 Jan, 2016 by Arun Sethuraman

The 1964 Alaskan earthquake was landscape-altering in creating/uplifting numerous islands in the Gulf of Alaska, providing an ideal system to study adaptive evolution of diversification in affected species – the threespine stickleback (Gasterosteus aculeatus) being a widely studied example. In … Continue reading →

It's not you, it's my genes: Sexual fidelity tradeoffs in prairie voles

Posted on 15 Dec, 2015 by Noah Snyder-Mackler

Many of you may probably already know the monogamous prairie vole as the yin to the promiscuous montane vole’s yang. Prairie voles are socially monogamous, which is an extremely rare trait among mammals. This trait has made the prairie vole … Continue reading →

The next, next generation: long reads facilitate assembly & annotation in large genome species

Posted on 10 Dec, 2015 by Melissa DeBiasse

The typical procedure for constructing a draft genome or transcriptome using current second generation, high throughput sequencing platforms involves generating short reads about 150 base pairs long, assembling those short reads into larger contigs, putting the contigs in the correct order to create … Continue reading →

Long distance dispersal of modern humans outside of Africa

Posted on 10 Dec, 2015 by Arun Sethuraman

Long distance dispersal (LDD) has long known to be an artifact of human migrations out of Africa. However, the effects of LDD on modern human diversity, and models of LDD in human colonization are yet to be characterized. Using an … Continue reading →

Pre-adapted algal ancestors colonized land

Posted on 7 Dec, 2015 by Stacy Krueger-Hadfield

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 →

Life fast, diapause young: The African turquoise killifish genome

Posted on 7 Dec, 2015 by Noah Snyder-Mackler

Your newly sequenced genome isn’t going to get into Nature, Science, or Cell just because it “hasn’t been done before”. You need to have a hook. And speaking of hooks, there are two new fish genome papers out in Cell! … Continue reading →

Bees brought to their knees

Posted on 27 Nov, 2015 by Stacy Krueger-Hadfield

As regular readers of TME will have read, this past summer was a whirlwind of sampling in which I took the briefest of holidays in the Southwest of England before attending the European Phycological Congress (read about the congress here and here). … Continue reading →
