🆕 in Ecosphere's "Vegetation Ecology" track: A hot & dry future may shake up Yellowstone forests—think fewer spruce, more fire-tolerant neighbors

📄Simulated postfire tree regeneration suggests reorganization of Greater Yellowstone forests during the 21st century

Great work led by @knowlton.bsky.social & hopeful takeaways for forests of Greater Yellowstone! Rather than failing to regenerate after fire, forests may shift in composition and structure throughout the 21st century.
New paper out now in Ecosphere (esajournals.onlinelibrary.wiley.com/doi/10.1002/...)! Forest landscape simulations in the Greater Yellowstone Ecosystem suggest that changes in postfire structure and composition, and not a conversion to non-forest, are the dominant response to future climate.

As the mean rate of forest disturbance is increasing, so does its temporal variance. Proof that Taylor's law also applies to disturbance ecology, and a warning of more severe future extremes. Paper led by @corneliussenf.bsky.social w/ @tommaso-jucker.bsky.social www.nature.com/articles/s41...
Taylor’s law predicts unprecedented pulses of forest disturbance under global change - Nature Communications
Large pulses of disturbance have been observed globally in response to climate change. Using Taylor’s Law, the authors show that those pulses were not unpredictable but expected given a strong scaling...

Hi! #journorequest here: For HCN, I'm looking to speak with #federal scientists from the West who are preparing for #fieldwork this upcoming season. How has the federal chaos affect your planning?

I'd be happy to offer anonymity. You can reach me at shien.kim@hcn.org or via Signal @shienkim.1721.

Conserving landscape dynamics, not just landscapes
Abstract. Protected areas form the backbone of modern conservation. However, the current policies and practices in protected areas reinforce a static view

Our new report finds utilities are falling behind on interim emission reduction goals promised to investors and customers. This trend is made more concerning given it is playing out against the backdrop of the Trump admin's attacks on climate policy.

Many of the nation’s largest electric utilities are not on track to achieve their interim emission reduction goals or the “net-zero” targets

New paper in #EcologicalMonographs w/ @monicagturner.bsky.social & E. Mavencamp! Among sparse/non-forested areas 34 years after the severe 1988 Yellowstone Fires:

- ~1/2 appear “locked in”;
- Plant communities shifted to resemble meadows;
- Aboveground C repartitioned w/ 96% stored in dead wood.

There are THREE! Count em THREE memoirs coming out in 2025/2026 by women/non-binary folks who have worked as wildland firefighters or hotshots. Here they are, for those interested in pre-orders or learning more about the authors.

Conveying results of #simulationmodels is tricky. We produced a video to help folks understand how #climatechange and #fire could affect the iconic landscape of Greater #Yellowstone. Would love to see this used for ecology classes and outreach. @ttkeller.bsky.social www.youtube.com/watch?v=cIp7...

Excited to connect with folks here! I work with forests, fire, and people who live with forests that burn. Last year, we partnered with the UW-Madison media team to produce a video on some of the Turner lab’s work in the Greater Yellowstone Ecosystem. Enjoy!
