“Tuck your pants into your socks – the ticks can be really bad out here,” graduate student Dave Frey tells the group of four students as they embark from their cars.
The resilient polymer tattoos placed on the leaves allow for "frequent and long-term monitoring of cellular ozone damage in economically important crops such as grapes and apples," Andrew says."We sel...
Climate change has increased the productivity of forests, according to a new study that synthesizes hundreds of thousands of carbon observations collected over the last quarter-century. The ...
The world's forests play an important role in mitigating climate change. Trees are carbon sinks -- they absorb more carbon dioxide than they emit. But according to new National Science Foundation...
Trees that grow fast, live long lives and reproduce slowly account for the bulk of the biomass -- and carbon storage -- in some tropical rainforests, a team of scientists reports in a paper published ...
A majestic ponderosa pine, standing tall in what is widely thought to have been the "center of the world" for the ancestral Puebloan people, may have more mundane origins than previously believed, acc...
Poplar trees are widely used in commercial products, but, like several other tree species, they emit gases to the atmosphere that worsen air pollution and alter climate. Now field trials in Oregon and...
Chocolate-producing cacao trees that are resistant to a major pathogen were identified by an international team of plant geneticists. The NSF-funded finding points the way for plant breeders to develo...
Flooding from torrential rains caused by cyclones and monsoons, as well as other catastrophic events, may move huge amounts of fresh wood to watery graves deep under the ocean, scientists have discove...
Researchers at the University of North Texas have found that two oak tree species, post oak and live oak, that are widespread across the U.S. South remove black carbon from the urban atmosphere. The f...

More than 90 percent of flowering plant species combine male and female characteristics in one plant. In the less than 10 percent where female and male flowers exist on separate plants, they typically...
The concept of heat islands -- densely built-up urban areas that are hotter than the rural and semi-rural landscapes around them -- has been extensively studied and is widely accepted.Now a new study ...
Woody vegetation, such as trees and shrubs, has increased dramatically in Ozark grasslands over the past 75 years, according to a study published this week in the journal Landscape Ecology.The study e...
As the number of droughts increases globally, scientists are working to develop predictions of how future parched conditions will affect plants, especially trees.New results published today in the jou...
