Genetic legacy of rare dwarf trees is widespread
Researchers from Queen Mary University of London have found genetic evidence that one of Britain's native tree species, the dwarf birch found in the Scottish Highlands, was once common in England.
Amazon rainforest survey could improve carbon offset schemes
(Phys.org) —Carbon offsetting initiatives could be improved with new insights into the make-up of tropical forests.
Bark beetles change Rocky Mountain stream flows, affect water quality
On Earth Week—and in fact, every week now—trees in mountains across the western United States are dying, thanks to an infestation of bark beetles that reproduce in the trees' inner bark.
A plague in your family: The independent evolution of harmful organisms from one bacterial family
For the first time, researchers have studied the Black Death bacterium's entire family tree to fully understand how some of the family members evolve to become harmful.
Study shows lasting effects of drought in rainy eastern US
This spring, more than 40 percent of the western U.S. is in a drought that the USDA deems "severe" or "exceptional." The same was true in 2013. In 2012, drought even spread to the humid east.
Chimpanzees prefer firm, stable beds
Chimpanzees may select a certain type of wood, Ugandan Ironwood, over other options for its firm, stable, and resilient properties to make their bed, according to a study published April 16, 2014 in the open-access ...
A European bear's point of view, finally on film
They love their larvae, snore like troopers when they sleep on their sides and, for reasons unknown, get a kick out of pushing over the trunks of dead trees.
Fire and drought may push Amazonian forests beyond tipping point
Future simulations of climate in the Amazon suggest a longer dry season leading to more drought and fires. Woods Hole Research Center scientists Michael Coe, Paulo Brando, Marcia Macedo and colleagues have ...
'Cherry tree from space' mystery baffles Japan
A cosmic mystery is uniting monks and scientists in Japan after a cherry tree grown from a seed that orbited the Earth for eight months bloomed years earlier than expected—and with very surprising flowers.
Method offers potential for understanding anti-bacterial resistance
Biologists could gain a deeper understanding about how species have evolved – and even find ways to address antibiotic resistance – using tools that were developed recently at Stockholm's KTH Royal Institute of Technology.
Hummingbird evolution soared after they invaded South America 22 million years ago
A newly constructed family tree of the hummingbirds, published today in the journal Current Biology, tells a story of a unique group of birds that originated in Europe, passed through Asia and North Americ ...
Researchers design trees that make it easier to produce pulp
Researchers have genetically engineered trees that will be easier to break down to produce paper and biofuel, a breakthrough that will mean using fewer chemicals, less energy and creating fewer environmental ...
Plants release chemical weapons and deploy insect armies in their defence
Animals have an easy life. They can run, hide, or bite back when predators are on the prowl. Plants cannot. Instead they have evolved to deploy a range of defence mechanisms including chemical warfare and ...
Phloem production in Huanglongbing-affected citrus trees
Citrus Huanglongbing (citrus greening disease) is highly destructive and fast-spreading, contributing to a reduction in crop yields in Florida and threatening the future of the citrus industry worldwide. Once infected, trees ...
