“Association scans” are just the first step to understanding local adaptation A rare glamour shot of Arabidopsis thaliana flowers (Flickr, Steffen Geyer) Genotype-environment association is one of the most fundamental phenomena of landscape genomics. A species’ adaptat…

For the Molecular Ecologist, I wrote about a cool recent preprint that shows how complicated the connections really are between landscape genomic scans for locally adapted loci and actual locally adaptive function

University Assistant postdoctoral University Assistant postdoctoral

Just extended the deadline to March 21 for this position in the Plant Phylogenomics group at the University of Vienna. It is sort of a "post doc plus" position funded for up to six years.

Please reach out if you want to chat - I'd love to talk to you about it!

The genetic architecture of polygenic adaptation under a network-derived trait The genetic architecture of adaptation varies across species, populations, and traits. While existing models capture aspects like the number of loci, effect sizes, and allele frequencies, they often o...

Thrilled to share new work from @stochasnick examining how gene regulatory networks influence quantitative trait evolution! His forward-time simulations reveal fascinating dynamics in the genetic architecture of adaptation. doi.org/10.1101/2025...

📢 Viewpoint in New Phyt. on polyploid establishment!
Key take-homes🧵
1. In contrast to earlier hypotheses that pollinators can help new polyploids establish, we suggest that pollinators mainly prevent polyploid establishment because outcrossing increases the strength of minority cytotype exclusion.

Ecological speciation with gene flow followed initial large‐scale geographic speciation in the enigmatic afroalpine giant senecios (Dendrosenecio) Mountains have highly heterogeneous environments that generate ample opportunities for lineage differentiation through ecological adaptation, geographic isolation and secondary contact. The geograph...
