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.”

3-D shape acquisition using water displacement as the shape sensor for the reconstruction of complex objects
A global team of computer scientists and engineers have developed an innovative technique that more completely reconstructs challenging 3D objects. An ancient...
Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.
To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
