Researchers Put a Number on Animals’ Earth-Shaping Effects
Wild animals expend 76,000 gigajoules of energy—the equivalent of hundreds of thousands of monsoons or floods—shaping our planet’s terrestrial and freshwater ecosystems.
Road Development May Put Habitats at Risk
New research links road construction with increased urbanization and more fragmented species ranges.
A New App Tracks Burrowing Animals That Weaken Levees
Researchers are calling on amateur scientists to help protect flood barriers in their communities.
Snowmelt Sends Caribou Packing
Researchers compared caribou tracking data with satellite observations to learn whether snowpack conditions trigger the animals’ arduous annual migration.
The Arctic’s Uncertain Future
Over the next century, the Arctic will change and look much different than it does today. Just how different is still unknown.
Sailing Spectators’ Sounds Could Harm Marine Creatures
Research delves into noise pollution caused by spectator boats at sailing events such as the America’s Cup.
Hungry Stingrays Shift Serious Amounts of Sediment
While digging for food on estuary bottoms, rays push around literally tons of sediment, changing their habitat in profound ways.
How Great was the “Great Oxidation Event”?
Geochemical sleuthing amid acid mine runoff suggests that scientists should rethink an isotope signal long taken to indicate low levels of atmospheric oxygen in Earth’s deep past.
In Hot Water and Beyond: Marine Extremes Escalate
A new study suggests marine life is increasingly faced with triple-threat events in which extreme water temperature, low oxygen levels, and acidification converge.
