How do you begin to approach wicked problems, those that span socioeconomic and ecological spheres, when solutions involve multiple and varied stakeholders? Researchers at the Kellog Biological Station LTER began to tackle one of U.S. agriculture’s greatest challenges, excess nitrogen pollution, by hosting “The N Roundtable,” to improve the flow of information through a farming landscape that has changed dramatically in the past few decades.

Ocean Hotspots for Carbon Storage
The global carbon cycle doesn’t have many off-ramps, but the deep ocean is one of them. Researchers with the California Coastal Ecosystem LTER have found that twice as much carbon finds its way to the deep ocean at mesoscale ocean fronts as elsewhere in the ocean.
The Spruce and the Hare: Backing Up Leopold’s Intuition
Snowshoe hares prefer many other plants to white spruce seedlings, but when the population of hares skyrockets—as it does about once a decade—they can decimate even a bumper crop of spruce seedlings. Researchers with the Bonanza Creek LTER reconstructed over 40 years of browsing history by analyzing the age and browse scars of thousands of seedlings and saplings at 18 locations on the floodplain of Alaska’s Tanana River.
Urban Streams Cycle Nitrogen as Fast as Unbuilt Systems
Urban watersheds—with their fertilized lawns, street runoff, treated and untreated wastewater—have proportionally more nitrogen flowing through them than undeveloped landscapes do. But are urban streams somehow less able to process that nitrogen? New research out of the Baltimore Ecosystem Study LTER says: no. The study, based on 385 urban watersheds and published in the journal FEMS Microbial Ecology, found that urban watersheds have similar, if not higher, nitrogen processing rates than natural areas.
Divergent water regimes influence algal diversity
Wetlands exist on every continent save Antarctica and manifest as a variety of habitats, from salt marshes to mangrove forests. They provide important ecosystem services, such as water purification and flood protection—often tied to their high productivity and diversity.
Desert Data Jam Award Winners
The Desert Data Jam is a unique competition that challenges students to make creative projects (such as songs, physical models, children’s stories, infographics, and games) that convey complex ecological data to nonscientists. In this sixth year of the Desert Data Jam, more than 400 students participated. The top five projects from each participating class were… Read more »
