Voices: Research on dust in Utah has never been more important. Trump’s proposed cuts put our economy and public health at risk. “The loss of this science doesn’t just mean fewer data points,” writes Kristina Young. “It means fewer tools to protect water supplies, fewer insights to guide wildfire mitigation and fewer answers wh...

Excellent piece by @kristinayoung.bsky.social on the critical threat facing the USGS's Southwest Biological Science Center. We must rally and fight this senseless attack on science!!

Integration of plant–soil feedbacks with resilience theory for climate change The resilience of ecosystems to climate disruption requires internal feedbacks that support the stability of ecosystem structure and function. Such feedbacks may include sustained interactions between...

A bit late but excited to see our new TREE paper out on integrating PSFs with resilience theory!

🚨 New paper, led by Cristina Barber. We used high-resolution aerial imagery to study tree mortality in a tropical landscape. Large, isolated trees were most likely to die--alarming finding! @ecologicalsociety.bsky.social esajournals.onlinelibrary.wiley.com/doi/10.1002/...

The monkey flowers are good there this year. We were just there last week surveying the buckwheat populations.

Human intervention or natural dynamics? Rethinking theories on woodland expansion | University of Nevada, Reno New research challenges long-standing beliefs about rising tree densities in the West’s dry woodlands

A nice summary from Nevada Today of our recent paper on Pinyon-Juniper woodland dynamics in @pnas.org. Check it out!

Geographic projections of population viability predicted by the female-dominant and two-sex models. Maps show past, current, and future range shifts based on the predicted probabilities of self-sustaining populations. The last panel shows the difference in geographic projections of population viability between the female-dominant model and the two-sex model for each season.

Dioecious plants have separate male and female individuals, and temperature sensitivity may vary between sexes. A study of a dioecious grass species, Texas Bluegrass, shows that poleward shifts will be shaped by male heat intolerance. In PNAS: www.pnas.org/doi/full/10....

We mention this in the paper, but our analysis can really only speak to what allowed for increasing density in stands that predate 1800, but not what allowed for expansion into new areas. But increases in density after 1850 in these stands are largely predictable given pre-1850 demographic rates.

Hydrology Paper of the Day @bkshriver.bsky.social on why woody plants are apparently more prevalent in dryland areas: long-term increases in tree population are responsible for more young trees, and low rates of tree establishment over the past 400 years in the Great Basin and Colorado Plateau.

Thanks, Trevor!

Finally, and importantly, we show the pattern we observe in PJ woodlands does not apply everywhere. Using a dataset from a ponderosa pine ecosystem in AZ, we show that unlike PJ there is clear evidence of increasing establishment rates associated with fire exclusion in this system.

Our results have broader implications for how we interpret forest and woodland histories. Stand age data are the net result of multiple processes: establishment rates, survival rates, and total population size. Interpreting stand histories from these datasets requires accounting for these processes.

We use age structure data from PJ populations across the western US. All of these populations are dominated by young trees. But using simple population models, we show that observed increases in tree establishment are highly predictable using pre-1800 tree establishment rates.

Why has woody plant density been increasing in dryland ecosystems? In a new paper in @pnas.org we show that increasing tree density in pinyon-juniper woodlands could largely be a result of long-term population growth, rather than recent anthropogenic effects. www.pnas.org/doi/10.1073/...

We begin reviewing applications next week!
