📢New paper in @AoB_PLANTS 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/aobpla… @EvanPerkowski 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 👇, link to paper in chain. 👉 research.reading.ac.uk/lemontree/trad… @EvanPerkowski

Annual science meeting of @schmidtsciences @Lemontree_UofR project hosted in @SeoulNatlUni @snucals1 was filled with curiosity and fun! The program included one day of open seminars, two days of science meetings, and two days dedicated to the Early Career Researcher (ECR) summer school. The open seminar welcomed nearly 100 participants and featured presentations covering a wide range of topics on Eco-Evolutionary Optimality principles. The talks sparked many engaging questions and discussions. The science meeting highlighted updates from various working groups. It was a valuable opportunity for all of us to see the overall progress of the project, which led many discussions. The ECR summer school combined lectures on theory with hands-on training in LiDAR and hyperspectral remote sensing. We enjoyed a series of social activities too! 🍺 🐟 🥩 @SandyHarrisonRe Colin Prentice Heather Graven Xu Liang @PierreGentine @trevorkeenan Karin Rebel Hugo Jan de Boer @StockerBeni @nick_greg_smith @WangHanSci Pier Luigi Vidale Anna Agusti-Panareda Martin Best Sophia Cain Natalie Sanders Sarah Jones

At 5pm today at #esa2025, @AlissarCheaib will present her poster: 'The satisfaction of leaf nitrogen demand under drought is modulated by soil nitrogen availability and drought severity" highlighting how water-nutrient interactions must be jointly considered in models. 👌🌿🪾

Today at #esa2025, Snehanjana Chatterjee will present: "The influence of arbuscular mycorrhizal fungi on plant resource use economics" in session COS-Mycorrhizae 2 (3.30-5pm). Her work examines how AMF affect plant resource use strategies under different water & nutrient regimes

#ESA2025 let’s grapple with the role of N and P on leaf and whole plant traits! See you today at 14:00 in BCC 349

It's almost time for #esa2025 and we've got our @TexasTech group heading there to present their LEMONTREE research. Have fun @nick_greg_smith, @EvanPerkowski,@AlissarCheaib and Snehanjana Chatterjee! For more info on their talks head over to the blog... research.reading.ac.uk/lemontree/lemo…

@biodning @Lemontree_UofR Thanks Ning!

@Lemontree_UofR @EvanPerkowski Congrats, nice work!

🌿 New blog post! How does nitrogen shape plant responses to rising CO₂? In short: leaf-level responses are driven by nitrogen demand, while whole-plant growth is constrained by nitrogen supply. Read more: 🔗 research.reading.ac.uk/lemontree/how-… @EvanPerkowski

Super happy to see our new paper out in New Phytologist, we show how plant carbon costs are modulated by plant nutrient acquisition strategy nph.onlinelibrary.wiley.com/doi/10.1111/np…

🌿🌍 New research by @GiuliaMengoli 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 & climate models! 🔗Read more: onlinelibrary.wiley.com/doi/10.1111/gc… @GlobalChangeBio

Check out this blog post summarizing main findings from our recent paper looking at leaf and whole-plant responses to elevated CO2!

New paper alert!!

New paper alert from the LEMONTREE team!🌿📈We explore how nitrogen dynamics shape plant responses to rising CO2 in @JXBot . Blog coming soon or you read check out the paper here: doi.org/10.1093/jxb/er…"

@DsouzaAjwal @nick_greg_smith @Ez_nwanne @JXBot Thank you! We thought so too. Scaling leaf photosynthesis to whole-plant productivity is much more complicated than a simple 1:1

@EvanPerkowski @nick_greg_smith @Ez_nwanne @JXBot The difference between leaf-level and whole-plant level photosynthetic responses is consequential, yet not included in several studies. Glad you included both and I’m thrilled to read the paper.

🚨 New paper alert! 🚨 Very excited to share that our (@nick_greg_smith, @Ez_nwanne) new paper, titled "Nitrogen demand, availability, and acquisition strategy control plant responses to elevated CO2", is now in press at @JXBot (1/5) academic.oup.com/jxb/advance-ar…

This work helps resolve the longstanding question as to whether nitrogen supply or demand drives plant responses to eCO2, showing that nitrogen demand regulates leaf-level responses to eCO2, while nitrogen supply constrains whole-plant responses. Please do check it out! (5/5)

In contrast, whole-plant responses to eCO2 were enhanced with increasing nitrogen fertilization, supporting the large body of work indicating that nitrogen limitation constrains plant responses to eCO2. Inoculation played no role in modifying whole-plant responses to eCO2 (4/5)
