Finally I'm back with research on Brassicaceae - on reproductive investment in relation to the environment - thanks to a very enjoyable collaboration led by @mjavad1991.bsky.social and @plantreproevo.bsky.social!
Our last work is out! led by @mjavad1991.bsky.social as first author and another smooth collaboration with @rosischmickl.bsky.social! We explore the evolution of male (pollen) and female (ovule) investment in Brassicaceae, if you're curious on the answers, it's 👇

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
“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…

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...

📢 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.
