Soil texturing by feel may be more art than science but it sure is a gratifying skill to master (for those soil inclined 😉). @umontana.bsky.social

Please see our new paper just published in Global Change Biology: “Intensifying fire season aridity portends ongoing expansion of severe wildfire in western US forests”. 🧪🌍🔥
Intensifying Fire Season Aridity Portends Ongoing Expansion of Severe Wildfire in Western US Forests
Area burned by wildfire has increased in western US forests over recent decades. However, high-severity fire—fire that kills all or most trees—is also an important metric of fire activity given its d...

I am pleased to share the most significant study that I have so far contributed to. We find overwhelming evidence that mechanical thinning and prescribed fire reduce subsequent wildfire severity across seasonally dry forests in the western USA. www.sciencedirect.com/science/arti...

Alright, let’s finally get to the bottom of this question: how do shorter high-severity fire return intervals impact soil carbon fluxes in subalpine conifer forests? Undergraduate research interns are on the case. 🕵️

Let's dive into this a bit. A short and very incomplete thread on US Forest Service research. 1/

It was a fun experience teaming up with UW engineers to explore the biogeochemistry of phosphorus recovery from dairy waste using cyanobacteria!

Can cow poop and cyanobacteria help close the nutrient loop? 💩🧪♻️

An incredible wildcard gift from a student today—a hand-knit blanket for my newborn son, designed to mimic a soil profile! She hasn’t taken my soils course yet, so horizons were a creative shot in the dark. Thick, dark mollic epipedon up top, or clay- and Fe-rich kandic Bt? Mollisol or Ultisol?

@teamrat.bsky.social & I argue, soil science, though crucial for solving environmental challanges, should not be defined solely by its applications

What a resource! The overwhelmingly favorite topic in my physical geography course this year was atmospheric processes & clouds. This looks like a banger.
Today my new book "Clouds" is published by Princeton University Press. It is a science book, but written in a popular style. In a new undertaking, we use mid-to-late 19th century impressionist art to show the various forms of clouds. Available here press.princeton.edu/books/hardco...

Have you ever had someone you care about the impacted by a tornado, a hurricane, an earthquake, a wildfire?

Evidence based decision-making helps keep us safe and ecosystems healthy.

Science helps protect us. Now it’s our turn to fight to protect the scientific enterprise in the US. #missoula 🧪

As above, so below? It’s quite clear western conifer forests are facing substantial environmental forcing from both climate and associated fire regimes changes. How are below ground support systems for trees - such as beneficial mycorrhizae being impacted? How does this impact regeneration?

In 2022, 68% of US faculty were non-tenure track, up from 47% in 1987, yet the “vanishing tenure-track” trend remains largely absent from graduate student recruitment conversations. An important reality to confront, especially over these next 4 years. www.aaup.org/AAUP/comm/re...

Today I submitted my first research proposal as a PI. Not for a big grant, but a v v small one I helped write with an undergraduate. It may not be the typical career metric in my field, but for me, it feels like success. Especially in this new political climate. Early UG research support is 🔑

Fighting everyday here @umontana.bsky.social to combat “the extinction of experience” for my students - education doesn’t need to be (and shouldn’t be) a textbook. To quote Leopold “Is education possibly a process of trading awareness for things of lesser worth?”
Extinction of experience among ecologists
Fieldwork-based research and education in ecology are under multiple threats and are progressively declining. We call for greater attention to this on…

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.

Compelling data from Leuthold et al. highlighting the importance of pyrogenic organic matter (PyOM) in soil C stabilization in grasslands. Over 60% of labeled PyOM-C and 50% of PyOM-N remained after 10 years. Needless to say, fire is critical for biogeochem function. www.nature.com/articles/s41...
