At only about 1,000 in the wild, Chinas giant panda is among the most endangered species in the world. But there is still hope if we act fast. The pandas greatest threat is habitat loss and new research identifies high-quality habitat that, if protected, could increase the species chances of long-term survival.
"The current network of nature reserves provides protection for less than half of the pandas remaining habitat and fails to conserve essential habitat for dispersal," say Colby Loucks and Eric Dinerstein of the World Wildlife Fund-US in Washington DC, and four co-authors in the April issue of Conservation Biology. The giant pandas range has shrunk from the lowland forests of southeast China, northern Vietnam and northern Myanmar to six mountain ranges along Chinas Tibetan Plateau, where only 24 isolated populations survive today. Now, however, there is a window of opportunity to protect more of the pandas habitat, thanks to two conservation policies recently adopted by the Chinese government to help control flooding. First, under the National Forest Conservation Program, logging is banned in natural forests until 2010; and second, the Grain-to-Green policy is restoring forests on steep agricultural lands. These policies "have the potential to protect and restore panda habitat across the pandas entire range," say Loucks, Dinerstein and their colleagues.
Giant pandas need both high- and low-elevation forests as well as dispersal corridors. They need both types of forest because each supplies their primary food during part of the year: during the summer, pandas eat a kind of bamboo that grows at high elevations; and during the rest of the year, they eat another kind that grows at low elevations.

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.
Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
