From Species Richness to Ecosystem Resilience: a Synthesis Study of Marine Consumer Nutrient Supply
Marine LTER sites come together to synthesize how consumer-mediated nutrient dynamics are changing throughout time and in response to disturbances.
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
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
Stream Dissolved Nitrogen Cycling Responds to Human Activity across the Landscape
A new global data synthesis of stream chemistry indicates human activities reduce streams ability to retain and transform nutrients.
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 »
Small Water Bodies with Big CO2 Effects
Credit: Via @ArcticLagoons on Twitter Arctic coastal watershed systems are some of the most threatened regions on Earth and have undergone substantial climatic, physical, and biological change with the warming of our Earth. Now, researchers at the Beaufort Lagoon Ecosystems LTER site have discovered that small coastal water bodies, especially ponds, are releasing carbon to… Read more »
LTER at Ocean Sciences Meeting 2020
In 2017, the LTER Network saw the addition of three new marine and coastal sites. The new sites—Northeast U.S. Shelf (NES), Northern Gulf of Alaska (NGA) and Beaufort Lagoon Ecosystems (BLE)—are all well-represented among the 41 talks and posters presented by LTER researchers at the 2020 AGU Ocean Sciences Meeting. Presentations from these and other… Read more »
Cold, Dry, and Phosphorus Limited: microbial activity in nutrient poor habitats
High elevation and high latitude ecosystems are particularly vulnerable to climate change impacts because they represent the upward range limits for organisms that are adapted to cold temperatures and low nutrient levels. Two of the biggest threats to high elevation communities are nutrient deposition (e.g. nitrogen) and climate warming. A new study by Bueno de… Read more »
Bolstering climate change resilience through modeling
Using models to flesh out alternative futures for the Everglades under different rainfall scenarios, researchers provide much-needed detail for water and environment managers.
Legacy carbon takes a hit as younger forest stands burn
In 2014, massive wildfires swept through the Northwest Territories of Canada, burning over two million hectares of boreal forest, as well as the highly organic soils on which they stood. Researchers with the Bonanza Creek LTER used this unplanned experiment to learn whether the carbon released from burned land had been recently deposited or if… Read more »
