Monkeys and toads define priority areas for conservation on a fine geographic scale
Scientific determinations of 25 global "hotspots" - habitats with high concentrations of unique species vulnerable to human activity - are too large to be effectively managed by local conservation authorities, much less put aside as protected areas. Researchers from the Center for Environmental Research and Conservation (CERC) are making even finer geographic distinctions within these hotspots by examining how evolutionary relationships within distantly-related organisms are distributed throughout a shared habitat. Their findings are being published in the scientific journal Evolution.
The research, led by Drs. Ben J. Evans and Don J. Melnick of CERC, a research unit of the Earth Institute at Columbia University, focuses on Sulawesi, the largest island in the Indonesian biodiversity hotspot "Wallacea" that is host to a suite of species found nowhere else in the world. They compared the distribution of genetic diversity in species of macaque monkeys (Macaca spp.) and toads (Bufo celebensis) that exist only on this island.
"There is a critical need to apply scientific technology and translate scientific findings for policy makers and conservation practitioners," said Professor Melnick, who is also CERCs Executive Director. "The approach we outline in this study does just that. It uses molecular methods to identify areas that are genetically and evolutionarily unique across disparate types of organisms, and thus of the highest priority for conservation. In so doing, it translates a general regional conservation concern into a fine scaled blueprint for action."

A new manufacturing technique uses a process similar to newspaper printing to form smoother and more flexible metals for making ultrafast electronic devices.
The low-cost process, developed by Purdue University researchers, combines tools already used in industry for manufacturing metals on a large scale, but uses...
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....
