As temperatures rise in many regions around the world, plant species whose ranges were previously limited by low temperature thresholds and intolerance to freezing are increasingly able to expand into new areas and possibly overtake established vegetation regimes. On Hog Island, an undeveloped barrier island off the coast of Virginia, a group of LTER researchers… Read more »
For those living in South Florida, sea level rise is a very real problem that’s impacting coastal areas right now, and is expected to worsen over the next decade. While most discussions on sea level rise in Florida focus on highly populated coastal cities such as Miami and Tampa, sea level rise is also having… Read more »
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.
Credit: Henk Sijgers. CC BY-NC 2.0The American residential landscape is a product of culture, reflecting social practices through its managed plant composition. As a result of urbanization and globalization, residential ecosystems are increasingly homogeneous, with the potential to impact ecological dynamics at ever-expanding scales over the next 50 to 100 years. Despite this trend, researchers… Read more »
Although the modern “American Dream” is no longer defined by white picket fences, this perception of the “ideal” homestead still holds some influence on cultural norms: cookie-cutter houses lining a cul-de-sac, each with a pristinely manicured green lawn. A collaborative study of residential lawns near several LTER sites found that the quest for this suburban… Read more »
What information is needed to predict where fires will start in desert grasslands and how big they will get? Soil type turns out to play a larger role than expected.
How-and when-do ecosystems change character? Are those shifts reversible? And what signs might precede them? Such questions are hard enough to answer in a single place. One might think that incorporating different kinds of ecosystems would only complicate the problem. But a group of scientists in the Long-Term Ecological Research Network is finding a remarkably consistent pattern by combining models and data across several long-term ecological experiments.
— Woody Guthrie, Dust Bowl Blues Woody Guthrie, John Steinbeck, and Dorothea Lange all documented the devastation of the Dust Bowl in works that remain resonant with Americans nearly a century later. Via song, prose, and photograph, these artists revealed the devastation wind erosion can wreck on a landscape and the people who rely on… Read more »
Biofuel experts identify a way to meet 25 percent of Congress’ 2022 cellulosic energy production goals Marginal lands unsuited for food crops can serve as prime real estate for meeting the nation’s alternative energy production goals. In the current issue of the journal Nature, a team of researchers working at the MSU’s Kellogg Biological Station… Read more »
