A changing Arctic drives a new generation of research
An experiment at treeline, one on the tundra, one in the Kuparuk. Each has provided researchers with valuable truths about how each Arctic system responds to change.
Gradient of Soil Fertilization Helps Tundra Shrubs Expand Across the Arctic
Scientists at the Arctic LTER find that different points along a gradient of soil fertility aid ectomycorrhizal and ericaceous tundra shrubs. Their findings hint at the potential for those two types of shrubs to co-expand over the Arctic—a previously unconsidered scenario that could have vast implications for the future of the northern tundra
Across fourteen LTERs, soil carbon is a “gatekeeper” on the nitrogen cycle
An LTER cross site synthesis effort reveals that soil carbon availability determines nitrogen mineralization and nitrification rates across a wide diversity of terrestrial ecosystems.
Arctic LTER: Fertilization, fire and plant community change
The Arctic tundra ecosystem has naturally low biodiversity and is experiencing changes due to the influences of climate change. Over the past 30+ years, researchers at the Arctic LTER site have developed a suite of experiments to study the effects of expected climate changes on the ecosystem as well as conducting continued monitoring of ecosystem… Read more »

Ready-to-teach R Environmental Datasets: the lterdatasampler R package
We are excited to share with the broader R community a new collection of 8 data samples geared towards teaching environmental data science!
Expanding the “bio” in biogeochemical modeling: including voles in arctic climate models
Explicit representation of voles improves models of the impacts of climate change on Arctic ecosystem function
Stop giving early and late Arctic seasons the ‘cold shoulder’, say LTER scientists
Climate change is hitting Arctic ecosystems hard – permafrost is rapidly thawing, releasing previously-frozen organic matter into the surrounding environment. Knowing not only how, but when, dissolved organic matter (DOM) and other nutrient concentrations are changing is important for predicting effects of climate change, but the picture is currently incomplete. A new paper from Arctic… Read more »
LTER Road Trip: Tundra roots may hold the secret to predicting a future Arctic
By Haley Dunleavy It’s a beautiful August day in the Arctic. The sun, now finally rising and setting after months of circling the sky, warms my face; neon yellows, pinks, reds, and greens of fall foliage speckle across the tundra, and most importantly, the previously incessant mosquitos have died off. I’m standing on a single-planked… Read more »
Ironing out the arctic carbon cycle
Adrianne Trusiak takes us through sampling to decipher the carbon cycle at Toolik Lake, home of the Arctic LTER.
