Juvenile trees in the Amazon rainforest have an increased ability to perform photosynthesis while under drought conditions. Some of the Amazon’s smaller understory trees, juvenile members of the same species as the canopy trees, are capable of changing the way they process water to withstand drought conditions and still continue […]
Douglas firs are the most abundant trees in North America. Their ecological niche spans Southern Mexico to the Northern Rockies. Warming Will Reduce Trees’ Ability to Slow Climate Change New research suggests that the most abundant trees in North America absorb less carbon dioxide as the world’s temperature rises. The […]
An international team of scientists have identified candidate resistance genes that could protect ash trees from the Emerald Ash Borer (EAB), a deadly pest that is expected to kill billions of trees worldwide. In the new study, published recently in Nature Ecology & Evolution, researchers from Queen Mary University of London […]
The issue of biosecurity is set to become increasingly important to prevent alien invasive pathogens entering UK habitats A study suggests that some types of environment help block the spread of ash dieback disease, which threatens millions of ash trees in the UK. Landscapes with hedgerows and woods made up […]

The 5,426m peak of active volcano Popocatepetl is the second highest point in Mexico R.ALFARO-SANCHEZ Trees growing near to an active volcano face an uncertain future for several years after an eruption, a study has suggested. A reduced ability to absorb essential nutrients from the soil and lower rates of […]
Oliver trees have become popular with gardeners in recent years GETTY IMAGES Severe restrictions will be placed on imports of some very popular trees and plants in an effort to halt a deadly infection.
