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 »

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.
Barrier islands’ harsh conditions, including nutrient and freshwater limitations and extremes of light and temperature, along with frequent large-scale disturbances, such as hurricanes, limit the number of plants species able to survive. As a result, successional trajectories can be convoluted.
The ice-covered lakes in the McMurdo Dry Valleys, a polar desert, rely on glacial melt for almost all their inputs. A recent study of Lake Fryxell suggests that in this environment even small changes in climate can impact biological productivity in the lake.
A recent experiment examined the impacts of increased nitrogen on salt marshes—and the all-important microbes within them.
Each forest reflects a legacy of past disturbances—from the literal detritus left behind a storm or fire to the prominence of particular species traits that enable species to bounce back after a specific type of disturbance.
