Mapping the 1.6 Billion People Who Live Near Forests

Global maps of places where people and forests coexist show that an estimated 1.6 billion people live within 5 kilometers of a forest. The assessment, based on data from 2000 and 2012, showed that of ...

Colorado's Famous Aspens Expected to Decline Due to Climate Change

Using computer modeling, researchers simulated how the distribution of quaking aspen, a native tree known for its brilliant yellow and orange foliage in fall and the sound of its trembling leaves, ...

Evergreen Needles Act as Air Quality Monitors

Every tree, even an evergreen, can be an air quality monitor. That's the conclusion of researchers who measured the magnetism of particulate matter on the needles of evergreen trees. That ...

Invasive Shrubs in Northeast US Forests Grow Leaves Earlier and Keep Them Longer

The rapid pace that invasive shrubs infiltrate forests in the northeastern United States makes scientists suspect they have a consistent advantage over native shrubs, and the first region-wide study ...

Researchers Discover Novel Molecular Mechanism That Enables Conifers to Adapt to Winter

Unlike broadleaf trees, conifers are evergreen and retain their photosynthesis structure throughout the year. Especially in late winter, the combination of freezing temperatures and high light ...

Potential and Constraints of Reforestation for Climate Mitigation

A recent study showed that practical considerations, beyond where trees could be planted, may limit the climate change mitigation potential of reforestation. Hence, there is a need to understand how ...

Global Warming Is Changing Our Plant Communities

In a comprehensive study of nearly 20,000 species, research shows that plant communities are shifting to include more heat-loving species as a result of climate ...

Fungal spores responsible for bitter rot disease, a common and devastating infection in fruit, do not encounter their host plants by chance. Turns out, they have a symbiotic association with the ...

Most Close Relatives of Birds Neared the Potential for Powered Flight but Few Crossed Its Thresholds

New research has resulted in an updated evolutionary tree of early birds and their closest relatives to reconstruct powered flight potential, showing it evolved at least three times. Many ancestors ...

Forest Growth in Drier Climates Will Be Impacted by Reduced Snowpack

A new study suggests that future reductions in seasonal snowpack as a result of climate change may negatively influence forest growth in semi-arid climates, but less so in wetter ...

Fragmented Forests: Tree Cover, Urban Sprawl Both Increased in Southeast Michigan Over the Past 30 Years

The extent of Southeast Michigan's tree canopy and its urban sprawl both increased between 1985 and 2015, according to a new study that used aerial photos and satellite images to map individual ...

Study Clarifies Kinship of Important Plant Group

Asterids comprise around 100,000 flowering plants, from heather to tomatoes. Up to now, their family relationships had not yet been fully clarified. A new study has now somewhat closed this knowledge ...
