Hey #Botany2026, mark your schedule for an amazing talk by Kelly González, postdoc in my research group on ecological niche modeling and whether riverweeds (Podostemaceae) care for anything other than river rapids!! Tomorrow at 2:15 pm at San Luis 1

Who at #botany2026 is thinking about which talks to see tomorrow? Maybe I humbly recommend our talk on Physalis phylogenomics where we ask the question, why are there so many tomatillo species 50 million years after a (famous to Solanologists) bottleneck? Tomorrow 1:30pm in San Ignacio!

#Evol2026 has been a blast!! Hope to see some of you mutuals at my talk this evening. Let’s talk about dogs and fossils and dog fossils 😎

Hope to see y'all at #Evol2026! I'll be talking about my simulation tests of cutting-edge fossilized birth-death models, and what we can learn from the Canidae phylogeny using these models. Come through! It'll be on Sunday (June 21st) at 5:15PM, room 22. Last talk first day 🤙

The branches of the plant tree of life become fuzzy for Andean clades! The evolution of many plant groups of the Andes remain unresolved. Here a breakdown of what happens for #Brachyotum, endemic to the Tropical side of these mountains.

Evidence of introgression amid phylogenetic conflict in #Brachyotum, a plant radiation from the Tropical #Andes New #AJB research by @evoyeyo.bsky.social, Ana Bedoya, Fabián Michelangeli, Lucas Majure, Carmen Ulloa Ulloa, & @tropicalbotany.bsky.social doi.org/10.1002/ajb2... #botany #plantscience

Above: Multiple phylogenetic trees with different topologies inferred with nuclear and plastid datasets for the Andean clade Brachyotum + allies. The different methods for the nuclear dataset include a concatenation with maximum likelihood, summary-methods (ASTRAL) and co-estimation (BEAST).
Below: Left, Brachyotum cutervoanum, a narrowly endemic species from northern Peru. Right, Chaetogastra sp., presumably and F1 hybrid between the genera Brachyotum and Chaetogastra, occurring at southern Peru.

Came to #ssb2026 for the original chicken figers and to pet the most adorable yellow lab ever #RocotoManzano. See you this afternoon in the "Rev the Bayes and Q the matrix" workshop, get ready for graphical models, math, and trait evolution!

Fun fact for #SSB2026: the original Raising Cane’s- the mothership- is in Baton Rouge, right next to the LSU campus. Come for science and community, and stick around for chicken fingers!
