New Special Collection: Fire in the Earth System
Papers are invited for a new cross-journal special collection presenting advances in understanding the physical and biogeochemical processes associated with landscape fires and their impacts.
The Massive Ice Avalanches of Mars
Ice avalanches may have traveled at speeds of up to 80 meters per second.
Lessons from a Post-Eruption Landscape
Four decades of research into biophysical responses to the 1980 eruption of Mount St. Helens have vastly improved our understanding of how landscapes react to cataclysmic disturbances.
The Give and Take of Mercury in Glacial Landscapes
As glacial ice melts, toxic mercury is released into the environment. But a new study shows vegetation may be an effective cleanup crew.
The Shape of Watersheds
Streams in flatter watersheds have carbon cycles more sensitive to temperature increases.
Are Beavers Nature’s “Little Firefighters”?
It’s about dam time: Beavers are acknowledged for their firefighting skills in five recent blazes.
