Free-Roaming Bison Graze Life into Grasslands
A new study suggests that Yellowstone’s herd of bison accelerates nutrient cycling, offering a glimpse into the North American plains of yesteryear.
Tracing Iron’s Invisible Transformations Just Beneath Our Feet
A new method that adds synthetic iron minerals to soils sheds light on hard-to-observe soil and sediment processes and may have a host of other applications in the Earth sciences and beyond.
Waterworks on Tree Stems: The Wonders of Stemflow
Stemflow hydrodynamics offers rich physics that seeks to describe water and matter cycling within the atmosphere-biosphere-geosphere with implications for water resources planning.
Warming Winters Sabotage Trees’ Carbon Uptake
In temperate forests, the biomass-building benefits of warmer growing seasons are offset by damaging variability in winter weather—a disparity that climate models may miss.
Water Tracks: The Veins of Thawing Landscapes
Tracing and tracking change in permafrost flowpaths could reveal the dynamics of warming poles.
Organic Radiocarbon Reveals its Inorganic Ancestry in Lake Geneva
Organic and inorganic radiocarbon ages resolve the origin and dynamics of carbon in the largest natural lake of Western Europe.
A Great Whale Conveyor Belt Transports Nutrients Across Oceans
Baleen whales shift huge amounts of nutrients, including nitrogen, from high-latitude feeding waters to tropical breeding areas.
Could Bubbling Oxygen Revitalize Dying Coastal Seas?
Reoxygenation approaches have shown some success in lakes, but their potential risks must be examined carefully before they’re implemented as solutions to improve the health of coastal waters.
Upwelling Near Fronts Initiate Offshore Phytoplankton Blooms
A new study finds that phytoplankton blooms, often seen near the separation point of western boundary currents, are supported by nutrient supply upwelling and cross-shelf transport.
