Climate warming causes local extinction of Rocky Mountain wildflower species
New research has established a causal link between climate warming and the localized extinction of a common Rocky Mountain flowering plant, a result that...
Laser technology takes Maya archeologists where they’ve never gone before
With the help of airborne laser mapping technology, a team of archeologists is exploring on a larger scale than ever before the history and...
Sea urchins erode rock reefs, excavate pits for themselves
Through their grazing activity, sea urchins excavate rock and form the pits they occupy. This activity may cause significant bioerosion of temperate reefs, according...
Scientists create ‘Evolutionwatch’ for plants
Using a hitchhiking weed, scientists reveal for the first time the mutation rate of a plant growing in the wild.
Tropical trees use unique method to resist drought
Tropical trees in the Amazon Rainforest may be more drought resistant than previously thought, according to a new study. That's good news, since the...
Ancient DNA tells tales of humans’ migrant history
Fueled by advances in analyzing DNA from the bones of ancient humans, scientists have dramatically expanded the number of samples studied -- revealing vast...
Theory suggests root efficiency, independence drove global spread of flora
Researchers suggest that plants spread worldwide thanks to root adaptations that allowed them to become more efficient and independent. As plant species spread, roots...
First evidence of surprising ocean warming around Galápagos corals
A new analysis of the natural temperature archives stored in coral reefs shows the ocean around the Galápagos Islands has been warming since the...
One thing leads to another: Causal chains link health, development, and conservation
The linkages between environmental health and human well-being are complex, and recent scholarship has developed a number of models for describing them. Unfortunately, these...
‘Chameleon’ ocean bacteria can shift their colors
Cyanobacteria -- which propel the ocean engine and help sustain marine life -- can shift their color like chameleons to match different colored light...
