Bonanza Creek Long Term Ecological Research
@bnzlter.bsky.social
The Bonanza Creek Long-Term Ecological Research program studies how changing climate and ecological disturbances are affecting Alaska’s boreal forest.
This NYT-profiled exhibit by the arts/humanities/sciences collaboration In a Time of Change is currently at the Univ. of Alaska Museum of the North. It will soon travel to Oregon State Univ.'s PRAx and Michigan State Univ.'s (SCENE) Metrospace. Check it out! www.nytimes.com/2025/10/19/a...

Comparing thaw probing, electrical resistivity tomography, and airborne lidar to quantify lateral and vertical thaw in rapidly degrading boreal permafrost
Abstract. Permafrost thaw across Earth's high latitudes is leading to dramatic changes in vegetation and hydrology. We undertook a two-decade study near Fairbanks, Alaska, to measure permafrost thaw a...

Bonanza Creek LTER is seeking a post-doctoral fellow! The position focuses on synthesizing long-term ecological data to study alternate successional trajectories in the boreal forest and explore their implications in a changing climate. Find out more and apply at careers.alaska.edu/jobs/post-do...
Overwintering ‘zombie fires’ aren’t doing what we thought they’d do A major new study of NWT wildfires that smoulder through the winter surprised the scientists involved and has some lessons for the territory's firefighters.

Northern soil microbes staying up all winter
We can’t see them, but there are more microbes — tiny fungi, bacteria, worms and other living things — in a teaspoon of soil than there are people on Earth.

This week Bonanza Creek LTER is helping host the annual meeting of the Long Term Ecological Research Network's Science Council, a gathering of scientists from research sites around the nation.
A sign that summer is ramping up in Interior Alaska: Calypso bulbosa in bloom in the Bonanza Creek Experimental Forest near Fairbanks.
Green-up turns white: Bonanza Creek LTER recorded this year’s green-up date in Fairbanks as May 2. Since 1976 researchers have recorded green-up when a hillside of birch and aspen trees near the Univ. of Alaska Fairbanks shows a faint green flush. Today the new foliage hides under fresh snow!
New in Nature - a phylogeny of over 10,000 species (all families, 58% of genera) inferred using Angiosperms353! We've been calling this the "Big Tree" paper for years and I'm glad to see it in print - fantastic work by the Kew PAFTOL team and many others! www.nature.com/articles/s41...

Testing germination rates of seeds collected last summer at long-term monitoring sites: a little greenery in the lab while it remains white outside! These alder seeds are about halfway through the two-week test. Our site with the longest data record was first sampled in 1957!
Wow, what a great paper. Last week I was just teaching about how climate change may shift the temperate/boreal ecotone Eastward (in principle), so this will be a fantastic data paper to pass on and draw from in the future.

Eugénie Euskirchen's team studied net release of carbon dioxide and methane from 2011-2022 at the Alaska Peatland Experiment near Fairbanks. Four sites with varied permafrost regimes all acted as slight annual sources of carbon dioxide and stronger sources of methane. doi.org/10.1111/gcb....
Drought response of the boreal forest carbon sink is driven by understorey–tree composition - Nature Geoscience
Drought response of the boreal forest carbon sink is driven by understorey–tree composition - Nature Geoscience
Carbon sink in young boreal forests is more vulnerable to drought than in mature forests due to the greater contribution and drought sensitivity of understorey relative to trees, according to carbon flux assessments of managed boreal forests in northern Sweden during the 2018 European summer drought.
