If you're interested in temporal sampling using herbaria, asters, or how floret counts change over time and environments, there's still time to check out their poster at P109!

If you're at #Botany2025, I'd love to see you at 5pm in the popgen session, where I'll be sharing on landscape genomics across the tiny, fragmentary range of the Gaviota tarplant!

Proud to share our new article on how lava flows reshape Hawaiian arthropod communities at species- & haplotype-equivalent scales!
We studied kīpuka—forest patches isolated by lava flows--with bulk arthropod samples & metabarcoding.
