After five incredibly happy years at Macalester, I recently moved to Chapman University. I am incredibly grateful to Macalester for my time there, and I am the scientist and person I am today because of the wonderful mentorship and inspiring student, staff and faculty community!
Poking my head up during sabbatical to (very late on) highlight a neat paper I collaborated on and led by Maya Almaraz (not on Twitter), with @whendeesilver @lesterlin @StephenPorder @PeterGroffman. Yay!
Nitrogen changes from insulating greenhouse gas forms to inert forms called dinitrogen as it moves between soil, air, and life. Scientists now have discovered that soils emit more nitrogen in its inert form than previously thought. eos.org/research-spotl…
For those interested in comparing ecosystem responses to drought across sites that differ in climate/productivity... this analysis will be useful. Nice work. Standardized indices to estimate sensitivity to drought across ecosystems onlinelibrary.wiley.com/doi/10.1111/av…
Hurricane #Fiona isn't Hurricane Maria. In terms of rainfall and flooding for Puerto Rico, it may even be worse. Already more than 25" of rain has fallen, and @NWSSanJuan warns that another 6-10" could fall in the next 24 hours. Fiona so far (L) — Maria (R)
“At least Fiona isn't like Hurricane María.” Puerto Rico was left without electricity. Thousands still live in damaged houses covered with blue tarps. People are worried. Judging by the videos, some would lose their homes. Five years later, Puerto Rico still hasn't recovered.
if you want to support Puerto Ricans in the aftermath of hurricane Fiona DIRECTLY: here's a thread of local organizations (don't donate to the red cross)
And it only took a newly formed Cat 1 Hurricane!!! Nothing near Maria. Zero lessons learned it seems.
The moment when floods generated by Hurricane Fiona wash away a bridge in Utuado that the National Guard had installed after Hurricane Maria:
Whooooooo!!! Legend of the game!!
Congrats to Erika Marín-Spiotta, professor @UWMadisonGeog, who was elected as an ESA Fellow for advancing knowledge of soil carbon stability and its response to land use change, and for serving as a global leader. Thanks for your important work @emsaurios! #ESA2022 🥳

New paper led by Marijn Bauters shows that Ca (and not N or P) is likely limiting secondary forest growth in Congo: nature.com/articles/s4155…
Considering how soil C is associated with minerals? Check out this amazing global analysis by @GeorgiouKat and co-authors for estimates of global stocks, driving factors behind the associations, and its ability to explain C accumulation. Wow! nature.com/articles/s4146…
Ever wondered how to manipulate big data with R? A thread on using Spark in R👇🧵 #rstats #spark #datascience
Drought can leave long-lasting legacies belowground... until a wet year resets the system. Roots are so dynamic. Repeated extreme droughts decrease root production, but not the potential for post‐drought recovery of root production, in a mesic grassland onlinelibrary.wiley.com/doi/10.1111/oi…
I know I just tweeted about a new paper, but really what's on my mind is yesterday's horrible school shooting, my fury over the lack of gun control in America, and my grief regarding the two-year anniversary of George Floyd's murder. Just a terrible week.
R.I.P. George. Today is miserable.
