Thrilled to share our paper in @NewPhyt: "Spectral ecophysiology: hyperspectral pressure–volume curves to estimate leaf turgor loss", led by @Castillo_RaizaJ, w/ @ProfZare, @gracepjohn, @Gerard_Sapes, Alston Lippert, & Nicole Mallen! #SpectralEcophysiology doi.org/10.1111/nph.19…

@MarylouMantova and I are excited to announce the 2024 GRS on ‘Plant Resilience to Stress’ for ECRS! Apply now to this and the following Gordon Conference for a whole week immersed in plant vascular biology: grc.org/multiscale-pla… Hope to see you there! 🍃 @GordonConf (1/2)

Deepening our understanding of plant water transport is crucial to deciphering their resilience to environmental stress factors such as: #drought 🌞 #fire 🔥 #diseases 🪲 📰+ details in our #TansleyReview in @NewPhyt 👇 nph.onlinelibrary.wiley.com/doi/10.1111/np… #PlantEcophys #PlantSci

And our jam-packed poster session in the afternoon! agu.confex.com/agu/fm23/meeti… (poster numbers 2645 -2665)!

We are excited for the #PSInet sponsored AGU sessions on ecosystem hydraulics happening tomorrow! See you bright and early for the oral session (w/Matheny, Anderegg, Boroski, Peters, Carminati, Pashalis, Konings, and Anderegg). 8:30 - 10:00 am. MW3008. agu.confex.com/agu/fm23/meeti…

Scientists call for a renewed legislative focus on scientific priorities for achieving nature-based climate solutions, including safeguarding Farm Bill research funding and IRA investments. nature.com/articles/d4158… #farmbill #climatesolutions

Putting tensiometers to the test! New #PSInet blog post from Ruth Magh (@ruth_magh) who took some Florapulse sensors for a spin! psinetrcn.github.io/posts/2023-12-…

PSInet is co-sponsoring a mixer with the FLUXNET community at AGU! It will happen on Monday, December 11th from 6-9 pm at the SOMArts Cultural Center in San Francisco. Should be a good time! Reserve your spot here: forms.office.com/Pages/Response… @FLUXNET_Coop @AmeriFlux #fluxcourse

🌿📢 Abstract call for #EGU24 is open! We're convening a session on plant and soil water status across scales, from empirical to modelling and remote sensing approaches. You can submit your abstract here: meetingorganizer.copernicus.org/EGU24/session/… @Novick_Lab @JessicaSGuo @MukundPR

Angiosperm stomata do not respond continuously to rising VPD but often start to close only once a threshold VPD is crossed. We found that this is linked to the triggering of abscisic acid biosynthesis at the threshold VPD, which then closes the stomata academic.oup.com/plphys/advance…

Water Potential 101 at #PhysFest4 in the beautiful Sevilleta.

New blog post on the #PSInet website! @GiardinaFra wakes up before dawn and gets to the bottom of how ET responds to water deficits (using deep learning). psinetrcn.github.io/posts/2023-08-…

On the pivotal role of water potential to model plant physiological processes academic.oup.com/insilicoplants…

We have Alex @PSInet_RCN visiting us to have exchanges on soil water potential and eco-atmos fluxes, with our annual department retreat @MPI_BGC

Reminder! Application deadline for Phys-Fest 4 in the beautiful Sevilleta is this week!

This new paper by @GiardinaFra shows that the sensitivity of evapotranspiration to water deficits varies massively across #FLUXNET sites. The next big question: How can we know this sensitivity across the globe and across the landscape? It's key for drought impact predictions...

A great opportunity for early career ecophysiologists!!

Finally, if you are at the @ESA_org meeting in Portland, consider attending this talk on Wednesday afternoon which will present the rationale and goals of PSInet. 2:30 pm, room 256. esa2023.eventscribe.net/fsPopup.asp?Mo… 6/6

Beyond submitting data, there are lots of ways to stay in touch and get involved. Have a look here! psinetrcn.github.io/join.html 5/6

PSInet will be a network of data, but also a network of people. We will sponsor a wide range of early career training activities, virtual and in-person workshops, conference sessions, webinars, etc. Keep an eye on our events page. psinetrcn.github.io/events.html4/6

PSInet will also promote community-developed best practices for continuous, in-situ plant and soil water potential monitoring. If you make these measurements in your field sites, we’d love to hear from you. Our DMs are open! 3/6

PSInet is open! This new @NSF -funded Research Coordination Network aims to vastly increase the accessibility of information about soil and plant water potential, emphasizing data collected in ecohydrological and ecological field settings. 1/6
