I reckon (hypothesize) the white ring will be a useful marker ring for your CRN. Wonder if it is the late frost of 2007 (or was it 2008…it predates my phone and the pic I took in KY. Pretty sure it was 2007)

The oblong/oval’ish brown patches?

Reminds me of when an entamogist told me about Thrips impacts on maples. This was down in the Smokies

That white ring is a signal. What year is that?

😂

I’ve still not seen it. Is it worth seeing?

They consulted with scientists at Lamont-Doherty Earth Observatory, including Wally Brocker, when developing the movie. Campus was excited when folks arrived

Repeatedly! When I was researching for my article on Trump and the Supreme Court's latest threat to the Clean Water Act, I learned the Cuyahoga River caught on fire not once, not twice, but over a dozen times

Picture of book "When Trees Testify" with text that reads: "We have been waiting for this. A botanical memoir, a history, a history with a Black lens-that takes us from roots to branches giving us the keys to an alternative retelling of the American landscape and the ways plants mark who we are and where we've been. This is an electric, bold weaving of ethnobotany, personal memoir, spirit and science and I am here for it." -MICHAEL W.

Grateful for @koshersoul.bsky.social's words about #WhenTreesTestify:

The speed with which salmon have returned to the Klamath - like the Elwha - after dam removal is overwhelmingly hopeful. And in both cases thanks to decades of tireless advocacy by local Tribes.

Warning. ⚠️ If you are writing an NSF GRFP, new this year, you need official transcripts to apply. Beware. They will not review applications without official transcripts. ‼️

The Equilibrium Conundrum Although an assumption of equilibrium dynamics underlies most ecological theory, the evidence for this dynamic in nature and in empirical studies is scarce. This creates an unfortunate disconnect bet...

Most major theories in ecology assume some sort of equilibrium, but only ~half of empirical tests acknowledge it & even fewer observed it in their system. Does this matter? How did the idea become so pervasive in ecology anyway? Find out in our new paper! onlinelibrary.wiley.com/doi/10.1111/...

Now I understand 67. This morning the clock said 6 and my body knew it was 7.

15 million Americans are going to lose their health care.

Because I enjoy SciComm, I offer public talks and tree-ring workshops. The two-day tree-ring workshops include opportunities to interpret and then synthesize information gleaned from each tree as a class.

If either of these activities fit your institution or communities, please reach out.

Professional Update:
Starting January 2026 I will begin my two-year Highstead Research Affiliate position at Highstead: highstead.net.

Among other activities, I will begin a new project identifying and mapping old-growth forests in Connecticut, the Catskills, and Adirondacks.

This morning Lisa Merkens summarized the highlights of her PhD in a short and dense talk, showing how we can use bird ecology, observations and city plans to study and model habitat connectivity and importantly, how to use this to improve cities for biodiversity.

I don’t know how much it might be out of the norm, but up here, a bit west pf Boston, a noticeable number of Red Maple kept their leaves until rather recently, some turning nice colors. It felt quite late (but was beautiful)

Over the past week, the president said the DOJ should pay him a quarter billion dollars, bulldozed half the White House to build himself a gaudy ballroom, bragged about murdering civilians in international waters, pardoned some more criminals, directed federal prosecutors to indict his opponents ...

Then, we ran a simulation for a megadrought in 2070 and nary got a vegetation response. A hot, multi-annual drought will do nothing? Hard to fathom.

Then, @dendroecologist.bsky.social realized the soil component might be holding too much water.

Are you talking about forecasts of the future? If so, when I first got a look at rainfall used for future simulations in the NE US, I was stunned. Just white noise with a slight trend. It is so much more dynamic, and then the oncoming heat.

Increasing Large Precipitation Events and Low Available Water Holding Capacity Create the Conditions for Dry Land‐Atmosphere Feedbacks in the Northeastern United States Land-atmosphere coupling at Harvard Forest is principally controlled by the low amount of precipitation retained as soil moisture rather than evapotranspiration More extreme rainfall resulted in ...

The second points out a trend in dry late-summer soils in a climate of increasing large rainfall events.

To me, this might signal climate change as starting to negatively impact/overcome the 500-year upward wetting trend
