Rapid evolution predicts demographic recovery after extreme drought Populations that are declining as a result of climate change may need to evolve to persist. Although evolutionary rescue has been demonstrated in theory and in the laboratory, its relevance to natural...

Big congrats to former Lowry Lab postdoc Daniel Anstett, who's paper: "Rapid evolution predicts demographic recovery after extreme drought" is out in Science today. www.science.org/doi/10.1126/...

David Marques was an amazing speciation genomics researcher, a passionate birder, and a wonderful friend, husband, and father. May he rest in peace. www.nature.com/articles/s41...

Postdoctoral position in Forest Genetics at @uni-freiburg.de with a focus on local adaptation and/or stress reaction of trees. The position combines research and teaching (4 SWS), and offers the opportunity to develop an independent research profile (4+ years).

How does the strength of genetic drift evolve over long times?

Asymmetric gene flow maintains range edges in a marine invertebrate | The American Naturalist: Vol 0, No ja

Three years since I collected the first amphipod for this paper and it is finally published! Feels like the end of an era.

We show that biased dispersal towards the range center maintains distinct edges in a beach amphipod.

This story is absolutely wild. Did you know that avocados change sex over the course of a day? And that it's controlled by a single ancient balanced polymorphism? This is flat our crazy

Empseb is simply the best. If you're a PhD student of evolutionary biology, do go there!

Excited to share the first two publications from our PERSIST (Predicting Evolutionary Rescue of a Species in Space and Time) project. Thanks to NSF-DEB for supporting this work! (1/3)

Infrared radiation may be one of the most ancient plant signals to pollinating insects Harvard researchers have discovered that cycads—one of the oldest living lineages of seed plants—heat up their reproductive organs to attract beetle pollinators and the insects possess infrared sensor...

Before flowers evolved with attractive colors and scents, what did plants use to attract insect pollinators? Heat may be one ancient strategy.

Valencia-Montoya and colleagues report their study of cycads in Science. Journal link in first comment.

Developmental Bias and Evolution: A Regulatory Network Perspective A recurrent theme in evolutionary biology is to contrast natural selection and developmental constraint – two forces pitted against each other as competing explanations for organismal form. Despite its popularity, this juxtaposition is deeply ...

Could you clarify this a bit? I personally found the parts I read to be really illuminating, and thought that it wasn’t a critique of the mainstream per se (but it probably was, given the history around the field then and development of EES)

Exciting!!

Most of the internet is down because of this one issue... this includes most academic journal websites!

Plos, Nature journals and biorxiv still seem to be up... for now. Made the mistake of closing many of the tabs I had open... sigh

So exciting to see a new method to model the evolution of G (and P) matrices on phylogenies. Another step in the direction of trying to bridge micro and macroevolution

Hybridization and introgression are major evolutionary processes. Since the 1940s, the prevailing view has been that they shape plants far more than animals. In our new study (www.science.org/doi/10.1126/...
), we find the opposite: animals exchange genes more, and for longer, than plants

A bit late, but really happy to see my first PhD paper out!
We studied trait-elevation relationships in multiple traits spanning growth, size (both above and belowground) and leaf economics to understand whether these align at within- and among-species scales.
