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.

Research by Bonanza Creek LTER's Grant Falvo is highlighted in Ned Rozell's recent article about wintertime soil microbe activity.

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.

Love that sunshine! The length of day in Fairbanks is now 10 hours 28 minutes, and we're gaining nearly 7 minutes each day.

Figure 1. Map of study sites in the Caribou-Poker Creeks Research Watershed (CPCRW). Darker shading denotes estimated permafrost extent (<4 to 54%). Sampling locations for sites C1-C4 are at the outlet of each catchment. Inset shows the location of the CPCRW in Alaska.

Figure 4. Metabolism and stream chemistry vary with permafrost extent. Center lines, boxes, whiskers, and points indicate the median, interquartile range (IQR), 1.5 × IQR, and outliers (n = 57–119 per site per year). ER = Ecosystem Respiration, GPP = Gross Primary Production, SUVA254 = specific ultraviolet absorbance at 254nm scaled by DOC, DOC = dissolved organic carbon.

Figure 5. Carbon (C) and phosphorus (P) co-limit respiration in laboratory incubations. Center lines, boxes, whiskers, and points indicate the median, interquartile range (IQR), 1.5 × IQR, and outliers of O2 demand (μmol O2 L−1 h−1) across all sites.

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!

Fresh snow covers recently emerged leaves on a birch tree.

A plot shows green-up dates from 1976 through 2024. Most years green-up occurs during the first three weeks of May.

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.
