Excited to share our latest paper led by ⁦@XuLian_PKU⁩ discussing the key role of windthrow and water deficit on the Amazon seasonality - Water deficit and storm disturbances co-regulate Amazon rainforest seasonality | Science Advances https://t.co/uzYSnplEQL

[Prof. Belinda Medlyn @b_medlyn]

Excited to see the hard-won #EucFACE Phosphorus budget published in @springernature today. Many thanks to lead authors @jiangmingkai and Kristine Crous!

[World Resources Institute @WorldResources]

🗺️@Meta, @WorldResources & @landcarbonlab have launched the first #AI-powered, 1-meter resolution global map of tree canopy height🌳

The model & data are made free & available to advance open source monitoring & improve our ability to adapt to #climatechange.

📢'The World Is Your Oyster' is for those who are born in global north countries--don't experience visa bureaucracy & emotional burden that non-white global south scholars do. Citizenship is a privilege that we need to recognize in the academe. 1/n

[Andrew Feldman @a_feldman24]

New paper! We use ECOSTRESS land surface temperature (LST) coupled with in-situ soil moisture measurements to evaluate depths of ecosystem water use across the United States. https://t.co/lpRxmbk1zi

[Nature Reviews Earth & Environment 🌈 @NatRevEarthEnv]

🚨New Review

@a_feldman24, @A_J_Felton, @alan_knapp, @carBenPoulter et al discuss plant responses to fewer but larger rain events

TL;DR: productivity typically increases in dry ecosystems but decreases in wet ecosystems

[Diego A. Marquez @DiegoMa_rquez]

Excited to share our new review on mesophyll conductance (gm) in @PlantCellEnvir with @FlorianABusch! We delve into gm's short-term responses to environmental changes, highlight crucial issues, challenges, and offer best practices for its study. 🌿🔬

[James Weber @Atmos_Pem]

Our paper https://t.co/KEi4LyYuYA is new in @ScienceMagazine today. We looked at the impact wide scale forestation (reforestation, afforestation and forest enhancement) would have on atmospheric composition and albedo, comparing these changes to the beneficial removal of CO2. 1/

[Wu Sun @dr_wusun]

New paper in @PlantCellEnvir: In heatwaves, transpiration may go up even when photosynthesis halts. We used leaf carbonyl sulfide (O=C=S) flux measurements to show that this decoupling may come from internal diffusion limitation instead of stomatal changes https://t.co/T1AMdSP6qr

[Ankur Desai @profdesai]

First accepted paper of 2024 from @HepingLiuWSU with #DesaiLab collab in GRL w/ LES simulation of scalar flux profiles and impact of energy imbalance from large eddies on CO2 flux (small but real and f of soil q and free troposphere profile). #CHEESEHEAD19 https://t.co/hfVVxkIWTt

Knowing how to give a good talk is a crucial skill to have, but it's mostly not formally taught very well. Here's a 🧵on my strategy for how to prepare for the presentation, actually present it, and then answer the questions.

[LEAP-STC @LeapStc]

Don't leave #AGU23 w/o hearing @WeiweiZhan98 (@PierreGentine Lab @CUSEAS) present "Understanding the Response of Ecosystem Water Use Efficiency to Rising CO2 Concentration: Insights from Global Long-Term Eddy Covariance Measurements!"
