Howdy #ESA2026 folks! Hit the hay early and check out tomorrow morning’s 8AM aboveground-belowground interactions session in Room 250D. I’ll be talking about mechanisms driving AM fungal-mediated impacts of garlic mustard on native plant physiology at 9AM. See you there!

The PhUnFETTy Lab will have a large showing at this week's #ESA2026. Come check out the cool work we've been doing!

Trying to finish up my #ESA2026 talk. Here's the current version of the last slide for anyone interested. Talk is Thursday at 8:30 in 255A.

📰Published📰The negative effects of an allelopathic invader on native plant photosynthesis are amplified after tree canopy closure🌳 buff.ly/0rixAsC 🧪🌍️

🎉Congrats to @stineb.bsky.social et al whose @newphyt.bsky.social Tansley Review on C + N cycles has been recognised as one of the Top 10 most viewed papers of 2024! Check out our blog on why it resonated, and how we continue to build on this work 👇 research.reading.ac.uk/lemontree/le...

New paper alert🔔My last PhD chapter is published📣 Our new study explains how the ratio of sapwood to leaf area🌿varies with hydraulic traits and climate on a global scale. Our theoretical model can capture almost 60% of trait variation. Stay tuned! Blog is on the way

📢New paper in @aobp.bsky.social led by LEMONTREE PhD Student Jan Lankhorst: Nutrient availability increases photosynthetic capacity without altering the cost of resource use for photosynthesis. Check it out👇 doi.org/10.1093/aobp... @eaperkowski.bsky.social et al.

🌳 Sugar maples sacrifice nitrogen use efficiency for greater water use efficiency while keeping photosynthesis steady. This field test of least-cost theory has big implications for land carbon models. Blog 👇 research.reading.ac.uk/lemontree/tr... @eaperkowski.bsky.social @nickgregsmith.bsky.social

Our annual meeting hosted this year by @youngryel.bsky.social at Seoul National University, brought together our international team to share research updates, plan our next steps and train our ECRs in remote sensing. A very successful week. Read more 👇 research.reading.ac.uk/lemontree/annu…

At 5pm today at #esa2025, @alissarcheaib.bsky.social will present her poster: 'The satisfaction of leaf nitrogen demand under drought is modulated by soil nitrogen availability and drought severity". This research highlights that water-nutrient interactions must be jointly considered in models.

This pm at #esa2025, @snehanjanac.bsky.social will present her work: "The influence of arbuscular mycorrhizal fungi on plant resource use economics" in session COS-Mycorrhizae 2 (3.30-5pm). This work examins how AMF affect plant resource use strategies under different water & nutrient regimes👌🌿

Thursday, August 14: I will present a poster titled "The power of traits: How population growth rate is shaped by leaf and plant traits across global environmental gradients" in LB 18-239 at 17:00 in the Exhibit Hall (poster)

Wednesday, August 13: @alissarcheaib.bsky.social will present "The satisfaction of leaf nitrogen demand under drought is modulated by soil nitrogen availability and drought severity" in PS 29-039 at 17:00 in the Exhibit Hall (poster)

Wednesday, August 13: @snehanjanac.bsky.social will present "The influence of arbuscular mycorrhizal fungi on plant resource use economics" in COS 122-02 in BCC 339

Come check out my talk this afternoon where I’ll try to make sense of N and P effects on leaf and whole plant traits! Starts at 14:00 in BCC 349. See ya there!

Today at #esa2025: @eaperkowski.bsky.social is presenting his talk: "Global response patterns of plant functional traits to combined nitrogen and phosphorus addition are driven by additive individual effects of nitrogen and phosphorus addition" Session: COS – Physiological Ecology 1. 1.30-3pm.

The PhUnFETTy lab will have four presentations at #ESA2025. These will cover plant ecophysiology, trait ecology, eutrophication, water availability, mycorrhizae, demography, theory, modeling, and more! Check out the flyer and replies below for more details. Hope to see you in Baltimore!

See you all at #ESA2025! Finally got a Monday afternoon talk slot 😁

The lab has new 2025 pubs on topics including: - CO2 acclimation - C4 trait spectra - Stem respiration - Phosphorus allocation - Predicting plant communities - Acclimation timescales (full links in replies) Check out more in a blog on the lab website here! www.smithecophyslab.com/news#mid2025...

We have a new paper out from our Powell Center C4 working group: "C4 photosynthesis, trait spectra, and the fast-efficient phenotype" The @newphyt.bsky.social Tansley Review led by Russ Monson explores what we know about the C4 trait spectra nph.onlinelibrary.wiley.com/doi/full/10....

🌿 New research by @giulimeng.bsky.social reveals how plants in arid climates adjust carbon uptake as soil moisture declines. A new empirical function improves predictions of water stress impacts on ecosystems & models!🔗Read more: onlinelibrary.wiley.com/doi/10.1111/... @globalchangebio.bsky.social

Check out this blog post summarizing our recent paper on leaf and whole plant responses to elevated CO2!

Check out our new paper! 2025 has already been quite the productive year for the lab!

Really excited to see this out! We show that the responsiveness of leaf #nitrogen to soil nitrogen #fertilization is highest where leaf nitrogen demand is greatest. We put together a short blog on the paper here: www.smithecophyslab.com/news.html#ch... A quick synopsis also in the thread below...

Omg um… hi everyone?? I log into BlueSky for the first time in a few months and follower list has kind of gone off the charts? Guess I should probably post a bit more frequently then, huh?

Interested in how and where trees move water? I'm hiring a plant ecophys postdoc to study hydraulic redistribution in Indiana forests. If you'll be at AGU and want to discuss, please reach out! jobs.carnegiescience.edu/jobs/postdoc...

🌱 New article in @aobp.bsky.social on Glycine max and Bradyrhizobium japonicum revealing how symbiosis reduces carbon costs and boosts growth when soil nitrogen is low. Full #openaccess 👉 https://buff.ly/3TUh3W5 @eaperkowski.bsky.social @nickgregsmith.bsky.social #PlantScience

Woo, final week or two of A/Ci curves until field season comes to a close! Excited to see what these data show about garlic mustard impacts on native plant carbon budgets.

(Sleepy) Doge and I are Pittsburgh bound! En route to four months of collecting gas exchange data to quantify carbon budgets of native flora growing in a manipulative garlic mustard removal experiment!
