Amazon inhales more carbon than it emits, NASA finds
(Phys.org) —A new NASA-led study seven years in the making has confirmed that natural forests in the Amazon remove more carbon dioxide from the atmosphere than they emit, therefore reducing global warming. ...
When eradicating invasive species threatens endangered species recovery
Efforts to eradicate invasive species increasingly occur side by side with programs focused on recovery of endangered ones. But what should resource managers do when the eradication of an invasive species ...
Mutual benefits: Stressed-out trees boost sugary rewards to ant defenders
When water is scarce, Ecuador laurel trees ramp up their investment in a syrupy treat that sends resident ant defenders into overdrive, protecting the trees from defoliation by leaf-munching pests.
Sloth truly deserves its name, biologists say
Imagine a creature so slothful that it snacks off its own fur and budges only once a week for a bowel movement.
Jack-of-all-trades slows down evolutionary tree
All living organisms are tips of an evolutionary tree that emerged over 3.5 billion years from a single common ancestor. Research in the Department of Bionanoscience at Delft University of Technology has ...
Redwood trees reveal history of West Coast rain, fog, ocean conditions
Many people use tree ring records to see into the past. But redwoods – the iconic trees that are the world's tallest living things – have so far proven too erratic in their growth patterns to help with ...
Recent decades likely wettest in four millennia in Tibet
Recent decades may have been the wettest in 3,500 years in North East Tibet – according to climate researchers at the University of East Anglia (UK) and the Chinese Academy of Sciences (Lanzhou, China).
Koala shows it's cool to be a tree hugger
Australia's cuddly koala rarely drinks water and doesn't have any sweat glands, long leaving scientists to wonder how it cools off in a heatwave.
Fish fossil yields jaw-dropping data on Man's past
The ancestor of all creatures with jaws and a backbone was not a sleek, shark-like beast but a toothless, armoured fish, said a study Wednesday that rewrites Man's evolutionary history.
Long-term memory helps chimpanzees in their search for food
Where do you go when the fruits in your favorite food tree are gone and you don't know which other tree has produced new fruit yet? An international team of researchers, led by Karline Janmaat from the Max ...
Oldest trees are growing faster, storing more carbon as they age, study reports
In a finding that overturns the conventional view that large old trees are unproductive, scientists have determined that for most species, the biggest trees increase their growth rates and sequester more ...
New algorithm identifies data subsets that will yield the most reliable predictions
Much artificial-intelligence research addresses the problem of making predictions based on large data sets. An obvious example is the recommendation engines at retail sites like Amazon and Netflix.
Discovery of a bud-break gene could lead to trees adapted for a changing climate
Scientists have confirmed the function of a gene that controls the awakening of trees from winter dormancy, a critical factor in their ability to adjust to environmental changes associated with climate change.
Arctic study sheds light on tree-ring divergence problem
Changes in tree-ring density in the Arctic may be evidence of changes in light intensity during the trees' growth, according to a new study by San Francisco State University researcher Alexander Stine.
