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
An LTER cross site synthesis effort reveals that soil carbon availability determines nitrogen mineralization and nitrification rates across a wide diversity of terrestrial ecosystems.
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 »
The shared spaces between LTER and NEON add value for both networks and for the research community at large.
We are excited to share with the broader R community a new collection of 8 data samples geared towards teaching environmental data science!
Explicit representation of voles improves models of the impacts of climate change on Arctic ecosystem function
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 »
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 »
Adrianne Trusiak takes us through sampling to decipher the carbon cycle at Toolik Lake, home of the Arctic LTER.
Climate change is already impacting polar habitats such as the Arctic tundra, where increasing temperatures are causing permafrost to thaw and exposing soil and organic matter that have been buried for thousands of years. Many scientists predicted that this soil, once exposed, would release a massive amount of sequestered carbon into the atmosphere, contributing to… Read more »
