The Ocean Sciences Meeting (OSM) has become an important venue for scientific exchange across a wide range of marine science disciplines, especially as human impacts on the oceans reach unprecedented levels. OSM, co-sponsored by the American Geophysical Union (AGU), the Association for the Sciences of Limnology and Oceanography (ASLO), and The Oceanography Society (TOS), will be held 11–16 February, in… Read more »
At the 2017 AGU Fall Meeting, held at the New Orleans Ernest N. Morial Convention Center in New Orleans, Louisiana, from December 11-15, 2017, dozens of LTER researchers will present new results on a range of topics, from how ecosystems recover from droughts and hurricanes to what manufactured ice storms can reveal about how to prepare for winter’s worst. Links to the abstracts for over 100 LTER presentations at AGU 2017.

This removal may lead to a more enjoyable experience for humans, but it constitutes a major loss of habitat for sandy beach critters, which use… Read more »
If carbon is currency, wildfires are the brokers; that is, they distribute carbon between land and air. In the short-run, fire emits carbon dioxide into the atmosphere. Over time, it also strengthens subsequent carbon uptake through plant regrowth. This exchange is like a natural Ponzi scheme – the carbon offsets from yesterday’s fires take up today’s emissions….

Credit: Marilylle Soveran CC BY-NC 2.0Moss and lichen make up a large portion of biomass in alpine and arctic ecosystems. With rising global temperatures, vascular plants have begun to colonize these moss-dominated ecosystems, potentially altering the soil composition and ecosystem function of these unique environments. Researchers with the Niwot Ridge LTER investigated how bacterial composition,… Read more »

They are now being used to track alligators, the rulers of the swamp, to learn more about their movements between freshwater and marine environments. Once attached, the GPS and radio transmission devices can track the… Read more »

A re-analysis of data from a large and influential decomposition experiment suggests that—at least in arid lands—the degradation of organic matter by light plays a much bigger role than previously understood. Back in… Read more »
While Florida, Texas, and Puerto Rico recover from a devastating hurricane season, another natural disaster rages on the other side the continent. Following a record-hot summer and dry conditions, the northwestern United States and Canada have experienced one of the most intense fire seasons on record. As global temperatures rise, scientists will need a better… Read more »
Recent research in Science concludes that high forest productivity relies on the presence of diverse tree species—a relationship that apparently hold true in biomes across the globe.
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.
