I study old-growth forests and climate change from trees to regions and seasons to centuries. A colleague termed it RetroEcology - https://broadleafpapers.wordpress.com/

The rapid warming and current drought in Iran appears to be a factor for the fires in the Hyrcanian Forest, a broadleaf mixed forest in a relatively wet region:

Time to get your public comments in on the proposed Waters of the U.S. rule that would strip protections for countless wetlands and streams.

Trout unlimited has a tool on their page that will automatically send your message to the EPA as well as your representatives:

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?

🌳💧📊 #PhDAlert! MSc in #ForestEcology or #EnvironmentalSciences? Excellent analytical and statistical skills in time-series analysis and experience with #treering methods🪵? We offer a #PhD position in #Dendroecology: apply.refline.ch/273855/1795/... #dendrosciences #ecology #ScienceJobs
Job offer: PhD in Dendroecology (f/m/d) You will be part of a project aiming to empirically disentangle atmospheric vs. soil drought impacts on intra- and inter-annual wood formation, and mechanistically model drought constraints on intra- and inter-annual tree growth dynamics (https://www.wsl.ch/en/projects/sad-tree) based on a unique monitoring network of 44 forest sites in Switzerland spanning 10 years of soil moisture and atmospheric climate data. In this context, you will contribute to the establishment and analysis of intra- and inter-annual time series of tree growth based on dendrometer, tree rings, and quantitative wood anatomy (QWA). You will be responsible for establishing improved empirical relationships of tree growth-environment interactions based on the long-term integrative Soil-Plant-Atmosphere-Continuum dataset (tree & stand traits, physical environment), analyzing: intra-annual water- and growth-related stem radius changes from dendrometer measurements, early-season wood anatomy related to water transport and rehydration, and long-term drought effects on growth using tree-ring widths. You have a Master's degree in forest ecology, environmental sciences, or equivalent. You should have excellent analytical and statistical skills in time-series analysis, preferably in dendrosciences and/or tree physiology. Ideally, you are proficient in programming and handling of large datasets, and have experience with tree-ring methods. You are able to efficiently expand and acquire knowledge in topics relevant to the project. You have a proficient command of written and spoken English, are able to work in a structured, efficient and independent manner, and have a high level of team spirit and have good communication skills.

Grateful for @koshersoul.bsky.social's words about #WhenTreesTestify:
"We have been waiting for this. A botanical memoir, a history, a history with a Black lens-that takes us from roots to branches...an electric, bold weaving of ethnobotany, personal memoir, spirit and science and I am here for it"
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 to spend two days on the Klamath watching chinook, liberated by dam removal, return to streams from which they’d been precluded since the Titanic sank. Fish are everywhere, in numbers that stagger the mind & locations that biologists figured would take years to repopulate. Too beautiful.

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/...
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...

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.
