Saturday site visit today at Abram's Falls with @ryanbstephens.bsky.social, beautiful fall weather, and the onset of fall colors in southern Appalachia 🍁🍂

Water cascades down a shallow creek over large slate rocks. Yellow and orange leaves mix with some still green in front of a pale blue sky

Two men leaning on hiking sticks are deep in conversation standing at the base of a large waterfall. Leaves in the foreground are starting to transition from green to the yellows and oranges of fall.

Deeply variegated leaves of wild ginger with pale green patterns overlying a dark mint green stick out against the browns of the forest floor

🚨 Please repost widely!🚨

I am recruiting a PhD student to join my lab next fall to work on forest and climate change ecology projects in southern Appalachia! Come join me in one of the most beautiful, biodiverse, and understudied parts of North America. Details below and happy to answer questions

An ad for a PhD position to start fall 2026 working with me at ETSU. For more info, please email at LeeBR1@etsu.edu.

You know your Google Scholar alerts are keyed in when it suggests your own papers and your student's theses!

Dang!

Nice, thanks! Was actually just looking at that one this afternoon.

I'm #teaching an introduction to research class in #biology for undergraduates this term. Anyone have a good suggestion for a short paper or text on questions, objectives, and hypothesis with a biology focus?

Ryan Stephens @ryanbstephens.bsky.social · Aug 15

Looks salvageable. We had an 18 inch white pine that absolutely initiated one of ours.

Ryan Stephens @ryanbstephens.bsky.social · Aug 11

Thanks! Wish we had more voices like yours here in the USA!

I'm giving a talk on Tuesday about carnivores as dispersers of mycorrhizal fungal spores as part of a special session on fungal spore dispersal. Come check it out if you are here in Baltimore and like fungi, carnivores, or trophic interactions. #ESA2025

“…when organisms interact can largely determine how they interact.”

Mechanisms that potentially contribute to the maintenance of interactions between bacteria, ectomycorrhizal fungi (EcMF), and land trees across varied developmental periods.

Our new global study led by @smriti-pehim-limbu.bsky.social is now out in @pnas.org. TLDR: Certain spore traits were linked to climate AND species range sizes! YES we can use traits to gain insight into env adaptations for microbes.

Happy to share that the first paper of my PhD is out!

We developed a trait-based framework 🌱🦜 to quantify how plant-frugivore interactions and animal movement shape plant functional connectivity—the dispersal of seeds between habitat patches.

Big day in the lab. Noah, successfully defended his thesis (my first student) and knocked it out of the park! I also submitted a manuscript from a project that we have been working on for about 6 years.

Our paper shows that most ectomycorrhizal fungal species (83% of OTUs) are "dark taxa": species we detect in DNA, but can't match to known species names. We map global "darkspots" - the parts of the world most in need of more research. @spun.earth @ethz.ch www.cell.com/current-biol...

Histograms are incredibly useful, interpretable, and common in BI. But building histograms that work well out of the box — no matter the data — is trickier than it sounds. We share some of the challenges faced, and decisions made, when designing histograms for Observable Canvases:

Designing better out-of-the-box histograms

Given how common histograms are in BI tools, you might think they’re easy to design. Think again. We share challenges we encountered, and how we handled them, while designing better out-of-the-box…

Last day of Animal Ecology today and my students surprised me with bear hats. I’ve been complaining about all the damage they do to our field sites and it’s been a running joke all semester. Of course every student presentation today also had bears.
