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!
Meanwhile, I have not posted on Twitter in several years, and am going to continue to be inactive on this platform. I have a profile under the same username at Bluesky and may be slightly more active there. But I am updating my affiliation above.
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.

For those interested in comparing ecosystem responses to drought across sites that differ in climate/productivity... this analysis will be useful. Nice work.

“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.

I want to remind everyone especially in the US that Hurricane Fiona has also made landfall in the Dominican Republic as well as the Virgin Islands. A lot of the times I feel PR is very central to news coverage of these disasters, but the Caribbean in whole will need assistance.

And it only took a newly formed Cat 1 Hurricane!!! Nothing near Maria. Zero lessons learned it seems. – at Mameyes I, Puerto Rico
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:

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!

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/…
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.
🎉 New article! 🎉 We review how advancements in collecting/analyzing high-frequency soil GHG data can help us understand "hot moments" of N2O flux - and thus the N cycle! With @tylerleeanthony @mayes_mamayes5 #TibisayPérez @debjani_sihi @whendeesilver. doi.org/10.3389/ffgc.2022.67…
Finally, I'd encourage you to check out the "New Frontiers and Paradigms in Terrestrial Nitrogen Cycling" special research topic put together by #MayaAlmaraz, @WendyYangUIUC and @michellewongca, which this paper is a part of. Yay! frontiersin.org/research-top…
