Many Forests in One: A Glimpse into the Amazon’s Diversity
In some areas of the Amazon rainforest, trees green up as a response to drought, while in others they die off. Scientists are trying to understand why.
Ancient Pines Could Reveal the Heat of Thousands of Past Seasons
A novel 3D CT scan approach unlocks temperature records preserved in the gnarled wood of bristlecone pines.
The Invisible Hand of Carbon Dioxide on Forest Productivity
A statistically robust approach applied to long-term flux measurements quantifies forest ecosystem response to increasing atmospheric carbon dioxide, providing a valuable benchmark for climate models.
Hurricanes May Prune Gulf Mangroves
Tropical storms knock down the tallest trees and stunt the growth of others.
Cosmic Rays Shed Light on Stone Age Timelines
Signatures of a long-ago solar storm, recorded in tree rings, helped researchers date a 7,400-year-old settlement in northern Greece.
Forests, Water, and Livelihoods in the Lesser Himalaya
Complex changes in land use, land cover, climate, and demographics are combining to stress water security for millions of people in the region.
Planting Trees May Not Be as Good for the Climate as Previously Believed
The climate benefits of trees storing carbon dioxide is partially offset by dark forests’ absorption of more heat from the Sun, and compounds they release that slow the destruction of methane in the atmosphere.
The Best Way to Kill Trees to Create Habitat
Standing dead trees—or snags—shelter animals, store carbon, and cycle nutrients. A long-term monitoring study found that lopping off a tree’s top branches is a good way to turn it into a snag within about 20 years.
