Tropical forests can harbor hundreds of species of trees in one square mile. Researchers reveal key factors in the spatial distribution of adult trees.

Major government and private funding is being invested in planting trees as a powerful tool to fight climate change. But new research shows a troubling bottleneck that could threaten these efforts: U.S. tree nurseries don't grow close to enough trees--nor have the species diversity needed--to meet ambitious planting and restoration goals.

The link between tree diversity and spider populations can help homeowners and other land managers better plan tree plantings to naturally mitigate the effects of climate change.

Scientists found that fires in America's dry conifer forests are burning hotter and killing more trees today than in previous centuries. The main culprit? Paradoxically, a lack of fires.

An exquisitely preserved fossil forest from Japan provides missing links and helps reconstruct a whole Eurasia plant from the late Miocene epoch.

Plant geneticists have identified a mutation in a gene that causes the 'weeping' architecture -- branches growing downwards -- in apple trees, a finding that could improve orchard fruit production.

Researchers use CRISPR techniques to modify lignin levels in poplar trees.

America's forests have a tough time in store for them. Climate change is increasing temperatures and decreasing moisture levels across the country, not a winning combination for trees.

A study has identified genes involved in development of stone cells -- rigid cells that can block a nibbling insect from eating budding branches of the Sitka spruce evergreen tree. The insect's attack has stunted the growth of these forest giants.

Many at-risk forest tree species will probably need biotechnology along with traditional tree-breeding approaches to survive, according to new insights.

Researchers have optimized a new technique to help forecast how volcanoes will behave, which could save lives and property around the world.

A new study that included millions of tree-year observations worldwide for the first time documents and analyzes the intricate balance between seed defense and dispersal by forest trees at a global scale.

Scientists have wondered what happens to the organic and inorganic carbon that Earth's Pacific Plate carries with it as it slides into the planet's interior along the volcano-studded Ring of Fire. A new study suggests a notable amount of such subducted carbon returns to the atmosphere rather than traveling deep into Earth's mantle.

Volcanic disasters have been studied since Pompeii was buried in 79 A.D., leading the public to believe that scientists already know why, where, when and how long volcanoes will erupt. But a volcanologist said these fundamental questions remain a mystery.

Researchers have found that the cooling effect that volcanic eruptions have on Earth's surface temperature is likely underestimated by a factor of two, and potentially as much as a factor of four, in standard climate projections.

As scientists try to understand the effect of climate on trees, advances in imaging technology are helping them see both the whole forest and every individual tree. High-resolution images taken by cubesats, small, shoebox-sized devices launched into low Earth orbit, are helping environmental scientists make more precise measurements about trees' response to a warming climate.

New research showed that the plume emitted by the Hunga Volcano eruption in 2022 created the highest lightning flash rates ever recorded on Earth, more than any storm ever documented.

The new study used a model of volcano fracturing to interpret patterns of earthquakes and ground uplift, and concluded that parts of the volcano had been stretched nearly to breaking point.

The Daitari greenstone belt shares a similar geologic make-up when compared to the greenstones exposed in the Barberton and Nondweni areas of South Africa and those from the Pilbara Craton of north-western Australia.

A study of the relationship between the growth rate of tropical trees and the frequency of genetic mutations they accumulate suggests that older, long-lived trees play a greater role in generating and maintaining genetic diversity than short-lived trees.
