Application deadline on Monday! PhD position @uni-freiburg.de in the @ecosense-sfb-1537.bsky.social project

I was actually wondering what mushroom has such a large basidiospore(?) 😁

Studied Butia eriospatha populations, GRA (open grassland in a and c), and FOR (forest in b and d).

In this study, we present estimates of fine-scale spatial genetic structure, mating system, and genetic diversity for both a typical grassland population and a rare understory population within an Araucaria Forest fragment.

This is the second publication from my Master’s thesis (completed back in 2017 at the Universidade Federal de Santa Catarina, Brazil!). After all these years, we finally "blew the dust off" the data and brought this piece to life.

Happy to share our new paper on the genetic diversity of the endangered palm 𝘉𝘶𝘵𝘪𝘢 𝘦𝘳𝘪𝘰𝘴𝘱𝘢𝘵𝘩𝘢: lnkd.in/gAFEj5xt

This project hits close to home—my father used to play and collect butiá fruits as a kid along the same riverbanks where I sampled my study populations.

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...

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).

Beyond Mendel: a call to revisit the genotype–phenotype map through new experimental paradigms Abstract. The long-standing notion that genotypes map to phenotypes through simple one gene–one trait relationships continues to shape both research in the

New Perspective!🔥It's fascinating how scientists from different fields but interested in the same question [e.g. genotype-phenoytpe relationship] can have such different perspectives. Here we put in our 2 cents wrt genetic effects being context-dependent, and pheno variation being mostly polygenic

Congrats, Jason! Great work!

I'm super excited to share that this article was published today in Science! www.science.org/doi/10.1126/...

All made possible by the fantastic group of donors, volunteers and scientists at The American Chestnut Foundation (tacf.org), HudsonAlpha Institute for Biotechnology, and our collaborators.

Fun news! @gcbias.bsky.social and I are teaching a 2-week online population genetics workshop this summer to raise money for the Center for Population Biology at UC Davis. We're trying to gauge interest -- please fill this out if you might be interested! And please share broadly!

Check out this preprint. Tianlin Duan led this project during her postdoc with me and Mike Whitlock.

It’s got a lot of stuff in it for those who are interested in the genomics of adaptation

Excited to finally have the pre-print up for this work on evolutionary rescue from my PhD at UBC!

Previous theoretical work on the effects of negative density-dependent growth on evolutionary rescue has uncovered inconsistent results, leading to an incomplete understanding of its influence.

Thank you so much, Katie!!!

I simply stood on the shoulders of giants. I'm incredibly grateful for the opportunity to be doing what I love. I could not have asked for a better supervisor @sallyaitken.bsky.social, lab mates, faculty @forestry.ubc.ca, and university! This journey has been amazing! Thank you, Sally!
