“The scariest thing about our findings,” said Carolina Useche of the Humboldt Institute in Colombia, “is just how widespread the declines of species are in the suffering reserves. It’s not just a few groups that are hurting, but an alarmingly wide array of species.” These included big predators and other large-bodied animals, many primates, old-growth trees, and stream-dwelling fish and amphibians, among others.
The researchers found that reserves that were suffering most were those that were poorly protected and suffered encroachment from illegal colonists, hunters and loggers. Kadiri Serge Bobo of the University of Dschang in Cameroon, Africa, said that it was not just what was happening inside a reserve that was important. “Almost as important is what’s going on outside it,” he said. “Eighty-five percent of the reserves we studied lost some nearby forest cover over the past two to three decades, but only two percent saw an increase in surrounding forest.” Deforestation is advancing rapidly in tropical nations and most reserves are losing some or all of their surrounding forest. The team found many nature reserves acted like mirrors—partially reflecting the threats and changes in their surrounding landscapes. “For example, if a park has a lot of fires and illegal mining around it, those same threats can also penetrate inside it, to some degree,” Ms Useche said.

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.
Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...
At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.
Multiferroic materials show magnetically driven ferroelectricity. They are attracting increasing attention because of their fascinating properties such as...
