The Biology Dept. @UMassBoston is searching for an Asst. Professor in "Microbial Ecology" (but 'microbial' is the operative word -- applicants studying evolution in microbial systems are also encouraged). For more info or to apply: employmentopportunities.umb.edu/boston/en-us/j…. Please share/RT.

Cool figure made with the help of #phytools in "Evolution of thumbnails across Rodentia" by @rafaelamissagia et al. in @ScienceMagazine. I especially appreciate that the authors acknowledged using phytools for the plots, something that's often overlooked! doi.org/10.1126/scienc…

If you're local to Concepción, Chile, & you like #phylogenies, consider registering for this workshop we're offering at @USanSebastian sede Concepción. 👇

Next week I'll be teaching in a workshop at @USanSebastian sede Concepción with @lukejharmon & hosted by Cristián Hernández Ulloa. I believe that enrollment is still open, so if you're local to Concepción, Chile, please check it out!

I suddenly realized why @Klaus_Schlp is a fan of this wine! #threetaxonstatement #phylogenygeek

I'm not sure how, but I almost completely forgot I did this in #phytools even though it was only, like, two weeks ago: "A Pagel '94 type correlation model with one binary trait and one continuous character" using the discretized diffusion approximation (blog.phytools.org/2025/07/a-page…).
