I had the immense privilege today of looking through the correspondence of Carl Peter #Thunberg, disciple of Linnaeus, who took over Linnaeus' professorship @uu.se. Hundreds and hundreds of letters + a handful of letters sent by Linnaeus to Thunberg!!! 🤩 @linneansociety.bsky.social

📣CALL FOR PAPERS!

Upcoming SPECIAL ISSUE: Evolution at species range edges

Guest Edited by Shengman Liu, John Pannell and Sophie Karrenberg

More information here: academic.oup.com/jeb/pages/ca...

Hi folks- I recently saw a call from a journal that was looking for novel findings in Plant sciences. I can’t remember if it was a special issue or what but it was specifically for results that might not be a full publishable paper but were nonetheless important data sets or findings. Any ideas??

Hi Folks !

Just a few more days to register for the POPGROUP meeting (deadline = this Monday 10/11/2025).

Join us in the beautiful city of #Lille just across the Channel for three exciting days of science and more !

Repeated evolution of flowers specialized for buzz pollination | Plantae If you’ve ever looked closely at a tomato flower, you might have noticed that its anthers cluster together in the center of the flower, making the pollen inaccessible to most insects.

Well done Charlie and team!

Increasing temperatures affect thoracic muscle performance in Arctic bumblebees - Nature Communications Increasing temperatures threaten cold-adapted pollinators such as Arctic bumblebees by disrupting their physiology. This study found that thorax acceleration during non-flight vibrations peaks at 25 °...

Just out! 📄

The labs of @nicrodemo.bsky.social (Uppsala) and Emily Baird (Stockholm) studied the temperature sensitivity of bee buzzes 🐝

Key findings:

- Frequency is driven by thorax temp

- Air temps > 25 C affect muscle function

- Little/no effect of species

Too warm to buzz? Check out our newest paper on how warming temperatures affect bee buzzes in the Arctic. Well done to Charlie and Guadalupe and other coauthors for this nice study in the Swedish Arctic! @hfspo.bsky.social

The project is about transmission patterns of bacteria and antimicrobial resistance (AMR) in aquatic insects. 🧬🦠 (1/3)

Two of the best years, also the program that changed the trajectory of my life. <3

Based on the MEMEs I have met—this is an excellent program.

Proud of the latest edition of my free intro biostats book.

book: ybrandvain.github.io/biostats/

Not complete but at a good point to take a break, and I think its quite usable

dm me with comments , ideas etc

Gracias Rosana!!!

This work is the result of a lot of persistence, my co-authors especially @draverbee.bsky.social and @nicrodemo.bsky.social, greatly improved by reviewers and handling editors. Poricidal anthers evolved multiple times but this phenotype stayed in lineages 50 my after the origin of all angiosperms.

We are looking for a physics/maths graduate with an interest in biology, or a biology graduate with strong computational/mathematical skills/interests, to join us as a PhD student working on biomechanical modelling of butterfly wing scale structure formation www.findaphd.com/phds/project...

Excited to dig into this paper!

Having previously enjoyed Dr Mary Jane Epps work showing Rhododendron calendulaceum buzz pollination, now I see there….a whole Ericaceae section of the buzz pollination phylogeny 🤩😍

Ericaceae is a fascinating group to look for buzz pollination!

Thank you Aimee!

Every day is a school day. Is never heard of buzz pollination before.

Thanks! The preprint had a long life before making it to the published literature :)

I cannot believe our work is finally out there and in @journal-evo.bsky.social ! This was an enormous group effort!

We provide an updated estimate of the number of buzz pollinated angiosperm species, genera, and families, look at consequences for diversification, number of transitions, and more!

Thank you Elin!!

How many plant species are buzz pollinated? After more than six years in the making, our paper on the convergent evolution of buzz pollinated flowers is out in @journal-evo.bsky.social. Thanks @draverbee.bsky.social @roszenil.bsky.social and all co-authors for your hard work! doi.org/10.1093/evol...
