Call for plant ecophysiologists! Do you have Fv/Fm or F0-rise data? Do you know someone who might? @seanmichaletz.bsky.social and @nicolebison.bsky.social would love to hear from you. (Bonus if your data are from Asia or Africa.) Please share widely! #ecology #botany #ClimateChange #HeatTolerance

Help us identify drivers of global variation in PSII heat tolerance kinetics. Seeking collaborators and data in Fv/Fm temperature response curves at multiple heat duration and F0-rise curves. Email Nicole dot Bison at ubc dot ca or Sean dot Michaletz at ubc dot ca. Map of sites contributed shows points in North and South America, Europe, and Australia but not Asia or Africa (or Antartica, on the very slim chance someone has data from there).

Excited to share our new paper on leaf scorching. 🔥Early leaf browning during heat and drought is often interpreted as premature leaf senescence - but it may reflect rapid heat damage. Separating these processes is essential. www.nature.com/articles/s41... @wslresearch.bsky.social

Excited to share to 2 recent papers. "Decoupled carbon assimilation and growth responses to aridity in temperate deciduous oaks." Main finding: photosynthesis≠growth & growth is more sensitive to drought. This likely has implications for forest carbon under climate change doi.org/10.1126/scia...

Decoupled carbon assimilation and growth responses to aridity in temperate deciduous oaks

We found that when temps hit 30°C+, C3 plants start struggling - their carbon metabolism gets disrupted, they burn through sugar stores faster, and even their isotope signatures change. Meanwhile C4 plants? They're basically chilling like "this is fine" 😎 www.nature.com/articles/s44...

Extreme weather events are linked to climate change, and while the "overall picture" has been wetter in recent years, "the rainfall comes more in extreme events, and then you can go for very long periods without rain," says @lamont.columbia.edu expert @mukund24rao.bsky.social. Via @nytimes.com.

New Tansley review paper from Zoe Pierrat & friends in @newphyt.bsky.social linking proximal remote sensing with ecosystem fluxes! Synergies and best practices for hyperspectral reflectance, SIF, thermal, microwave and lidar 🌈🌲🗼🛰️🧪 nph.onlinelibrary.wiley.com/doi/10.1111/...
Overview of proximal remote sensing instruments at a flux tower site. Shown are three eddy-covariance towers with sonic anemometers collecting data to derive ecosystem fluxes. Shown for spectral reflectance and solar-induced fluorescence (SIF) is a hyperspectral sensor with a narrow field-of-view (FOV) and multi-directional scanning capabilities (Sections II.1 and II.2). We also show the direct emission of SIF from the forest canopy (Section II.2). For thermal infrared radiation, we show a fixed thermal camera and thermal radiation coming from the canopy (Section II.3). For microwave, we show two potential arrangements with antenna A receiving direct signals from under open-sky conditions as well as signals that are reflected from the underlying vegetated surface, and antenna B receiving a direct signal that is propagated downward through the vegetation canopy and attenuated by its moisture content (Section II.4). We also show a light detection and ranging (LiDAR) instrument emitting light to get a 3D representation of canopy structure (Section II.5). Above the forest are a drone, aircraft, and satellite to emphasize the potential of proximal remote sensing to complement observations across scales. In the inset plot, we show sample reflectance spectra for vegetation and wet soil and highlight key wavelength ranges for spectral reflectance. We also show typical SIF retrieval windows and LiDAR emission windows. Next to the reflectance spectra, we show sample radiance in the thermal infrared region, with example spectra for warm soil and cool vegetation. Finally, we show key measurement wavelength bands for microwave backscatter.

Future #climate projections of tree cover suggest the boreal forest is headed for an open state (⬇️🌲in south & ⬆️🌲in north) But, how will boreal tree cover dynamics influence—and be influenced by—climate feedbacks? We discuss this in a new commentary @pnas.org. 🧪 www.pnas.org/doi/10.1073/...
Simplified conceptual diagram of potential feedbacks associated with a projected open forest state in the year 2100. The transition to an open forest state is closely tied to feedback processes such as changes in biomass and species composition, disturbance (wildfire, insects, wind), albedo, water availability, and permafrost dynamics
