The Tumber-Dávila Lab, Dartmouth College Dept. of Environmental Science, is seeking a full-time lab manager/research assistant to contribute to research on belowground ecosystems response to global change.
COME JOIN US! 🧪🌳🌲🌎

For undergrads interested in an ecology REU, the deadline to apply has now been pushed back to Monday 2/9 for all NSF REU programs!
We are funded!! No shutdown for US Forest Service (and others, obvs) come Feb 1!!!!!!!!!!
The @harvardforest.bsky.social Summer Research Program in Ecology REU Applications are now OPEN!
We are looking for two students to join our group focused on measuring root traits in:
1. Climate Interactions and Forest Fragmentation Experiment
2. Black Gum Swamp
Plus many other exciting projects!
NASA is being told to cancel 19 *active* missions to save $6B, which looks to be less than the ICE *hiring/retention* budget going forward.
I need people to let that sentence sink into their bones for a minute.
Within the past week, in my terrarium which has been SEALED for 1.5 years...
A violet has flowered!
A beetle has emerged!
A wasp has emerged!
What?!
“Since World War II, ‘government R&D investments are pretty consistently driving about 20 to 25 percent of all U.S. private-sector productivity growth.’”
Our MS student is leading a huge effort to remeasure soil respiration (200+ collars!) around the Bartlett AmeriFlux tower (US-Bar) after 20 years of rising CO2 and declining N deposition. Is the forest allocating more C belowground to offset N limitation?
...And so many painted trillium!
And black birch sap running like crazy from drill holes!
20 point dendrometers installed and ready for the growing season!
An underwater camera set up 55 years ago to try and photograph the Loch Ness Monster has been found by accident by a robot submarine.

⚡⚡Did you know that some trees WANT to be struck by lightning?⚡⚡ Well, trees don't "want" anything, but if they did, then Dipteryx oleifera trees would want to be struck by lightning. Just published yesterday (tinyurl.com/ltbnft) and described in this video: www.youtube.com/watch?v=QwX_... (1/5)
This is unabashed fascism. Trump executive order on Smithsonian targets funding to programs with 'improper ideology' apnews.com/article/trum...
A global meta-analysis of soil respiration in response to elevated CO2 www.sciencedirect.com/science/arti...
Just heard that Trump is putting an end to atmospheric monitoring site NY67 that is run out of my lab. This is one of the oldest NADP sites in the US, continually measuring acid rain and other pollutants since 1977. Closing it down is tragic.
Image shows text and three photos (aerial of research in the forest, upwards to a research tower, and researchers looking at a tree). Text includes the following: Tuesday March 18; Harvard Forest Annual Ecology Symposium: Future Directions of Research and Education at the Harvard Forest; Register to attend online!
📢 Our Annual Ecology Symposium is next week! 🌳🔬👨🏽🎓 Zoom in to hear exciting research & education updates from HF researchers & associates. rb.gy/c0bjp5
Congrats to Samuel Jurado on his first first-authored paper! We found that larger rain events lead to lower soil moisture, creating dry land-atm feedbacks in the NE US by increasing the height of cloud formation.
Research @harvardforest.bsky.social thx to @ameriflux.bsky.social & NSF REU & LTER
Firings are happening right now at the National Science Foundation. Essential staff are being cut.
This isn’t about the budget. If it was, they’d be going after the military (17%) or state appropriations (38%). NSF is 0.7% of the federal budget. All federal employees make up only 4% of the budget.
Pretty much every single person among the 100,000s the Trump administration is summarily firing is someone who works hard at a job where they earn much less than they could in the private sector, precisely because they believe in public service.
Worried about illegal take over of our federal agencies by unelected tech bros who are stealing our data and wrecking the good work those agencies do? Then call your entire congressional delegation, representatives and senators, as I did this morning. I was able to leave messages on all four of mine
This is absolutely batshit crazy. It's infuriating... Weather information is SO important. NOAA weather warnings are life saving, from North Carolina to California to New Jersey to Florida, etc.
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.
