Based on data from Costa Rica spanning 1947 -- 2014, the authors of a new study found 50 percent of secondary forest patches were re-cleared within 20 years, and 85 percent were re-cleared within 54 years. This suggests that committing to reforesting lands for the long term, even if smaller in total area, may provide greater benefits (habitat, carbon storage, etc.) than quickly reforesting large areas (as many nations have promised under the Bonn Challenge).
A wide ranging international study that genetically analysed the DNA of a series of famous and controversial ancient remains across North and South America has discovered that the Spirit Cave remains -- the world's oldest natural mummy - was a Native American. They were also able to dismiss a longstanding theory that a group called Paleoamericans existed in North America before Native Americans.
New research has assessed the impact of global warming on thousands of tree species across the Amazon to discover the winners and losers from 30 years of climate change. The analysis found the effects of climate change are altering the rainforest's composition of tree species but not quickly enough to keep up with the changing environment.
A warmer, drier climate is expected is increase the likelihood of larger-scale forest disturbances such as wildfires, insect outbreaks, disease and drought, according to a new study co-authored by a Portland State University professor
A new study has shown vultures use their very own social networks to take advantage of thermal updrafts which help them fly vast distances. A team from Swansea University examined how the vultures seemed to make risky but efficient choices when it came to their flight patterns by observing other birds in the network.
But if that's the case, what is the source of the East Antarctic Ice Sheet's massive ice streams? In the course of an extensive Antarctic expedition, researchers from the Alfred Wegener Institute Helmholtz Centre for Polar and Marine Research (AWI) recently investigated several lakes beneath Recovery Glacier that had been previously detected by satellite remote sensing.
A new study reveals process of an extreme spring cold spell, which happens over North China. Continuous negative temperature anomalies can have disastrous effects on the wheat yield, inducing yield losses of up to 20% or more.
The University of Cincinnati is working with the Nevada Bureau of Mines and Geology to add specific details on landslides to the state's map of known hazards.
Landfill gases contain numerous contaminants, but one group has demonstrated a promising new application of plasma technology capable of removing such compounds. Researchers have demonstrated an experimental plasma device capable of cleaning gas samples of D4, one of the most common siloxanes. Drawing on a technique for creating plasma called dielectric barrier discharge, the group was able to significantly reduce the amount of D4 samples after treating it with a helium-based plasma.
For sweeping drama, it's hard to beat hydropower from dams -- a renewable source of electricity that helped build much of the developed world. Yet five scientists from Michigan State University say that behind roaring cascades is a legacy of underestimated costs and overestimated value.
