Climate change could dramatically increase the forest cover of the Earths mountains, ecologists are predicting. Using data from the Austrian Alps, ecologists have developed a model that predicts the area covered by the local pine, Pinus mugo Turra, will increase from 10% today to 60% by the turn of the next millennium. The findings are published in the current issue of of the British Ecological Societys Journal of Ecology and, the authors believe, this is the first paper to model tree line dynamics driven by climate change on a landscape scale in both time and space.
The Earths climate has warmed approximately 0.6°C over the past 100 years and the rate of warming looks set to accelerate. Alpine tree lines are assumed to be particularly sensitive to climate change, with high mountain forests predicted to shift their ranges up-slope at the expense of alpine vegetation.
According to one of the authors, Dr Stefan Dullinger of the University of Vienna: “Shrinkage and fragmentation of alpine habitats, as a consequence, may pose a serious threat to populations of many alpine plants, especially to regional endemics. On the other hand, expansion of mountain forests may also improve certain ecosystem services for human welfare, such as erosion control and increased water holding capacity in many high mountain water catchments.”

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
