Postdoc Jake Montgomery will be talking at 11:30 about long-read resequencing approaches to understand the evolution of a complex gene amplification conferring resistance to round-up herbicides

And I will be presenting work led by Postdoc @rpineau.bsky.social at 11:15 on the genomic response to drought across spatiotemporal scales in waterhemp!

Sampling herbarium tissue

Really great couple of days with the lab group!!!

We are in our second season of collections for an on-field select and resequence experiment with sites across the Midwest, and gearing up for some more herbarium genomic work (perfect time of year to visit @mobotgarden.bsky.social for sampling).

Minimizing detection bias of somatic mutations in a highly heterozygous oak genome Somatic mutations are particularly relevant for long-lived organisms. Sources of somatic mutations include imperfect DNA repair, replication errors, and exogenous damage such as ultraviolet radiation....

Interesting. Highly complementary to our paper (unfortunately not cited) published three years ago in Peer Community Journal, in which we reanalyzed the same oak data using the same software for somatic mutation detection. peercommunityjournal.org/articles/10....

Pathogens and planetary change - Nature Reviews Biodiversity This Review explores the relationship between emerging infectious diseases and biodiversity loss, and how both are connected to global environmental changes in the Anthropocene.

There's a lot of replies to our new paper talking about how capitalism or overpopulation are the real enemy. Without getting into whether that's true of the climate emergency or the sixth mass extinction (🙃), I want to briefly explain why pandemics are different. www.nature.com/articles/s44...

New preprint up! We sequenced hundreds of samples from across one of Earth's oldest living organisms - the Pando aspen clone - to understand how mutations accumulate and spread in long-lived clonal organisms. Our results were…surprising. 1/30
