Excited to present my PhD work today on adaptation and maladaptation under climate change in Arabidopsis at #evol2026 at 4:45pm in Evolutionary Ecology: Adaptation! Come by to learn about what happened under this rainbow as well as my new final chapter quantifying global adaptation lag! 🌱🌱🌱

Finally encountered wild Arabidopsis thaliana!! I’ve known this plant well for 5 years now, and we happened to stumble upon it on the last day of Moi’s field course in Yosemite! 🌱🏔️

Yay to spending time with plant nerds! Thank you for the tour and specimen viewing at @stanfordjrbp.bsky.social

We monitored these populations for 3 years, and found that population growth rate decreased as the treatments became more stressful. Further, "high risk" populations (either high load or low local adaptation scores) had a higher stochasticity for recovery after a single year of water stress.

Crucially, we found a significant interaction between load and local adaptation, which grew stronger as the environment became more stressful. This suggests a synergistic decay of fitness resulting from locally adaptive variants, globally maladaptive load, and high water stress environments.

We found that populations with a low number of local adaptation alleles or high mutation load had decreased fitness in our highest drought stress environments.

A special find was this chaparral clarkia, Clarkia affinis, which I only found one of and it was growing proudly on this large rock.

Very fun spring wildflower spotting this weekend on a hike at Sierra Vista Open Space Preserve! 🌸🌼🌱 (peep Castilleja foliolosa, Dipterostemon capitatus, Calochortus albus, and Stachys rigida)

Check out this funny Arabidopsis grown outside in our common garden at UC Berkeley. This plant experienced a lot of herbivory and the herbivorized center became very woody?

Beautiful premiere of The Land Around Us by several lab mates! This documentary followed their journey through learning about land and our relationships to it in the Bay Area from four local experts with different approaches to stewardship and perspectives on the earth around us.

Moi is water Arabidopsis the same outside three years ago at Stanford and Carnegie
