Over half of all plant species in Europe are at serious risk because of climate change. This is the finding of an international team of scientists working on the ALARM project led by the Centre for Environmental Research in Leipzig-Halle (UFZ). Preliminary findings have recently been presented in connection with the UN Conference on Biological Diversity in Curitiba, Brazil.
The situation is expected to become particularly dramatic at middle to high altitudes in mountainous areas. The mountain flora there is very specialised and would therefore be less able to adapt. As well as the Alps and Pyrenees, this primarily affects large stretches around the Mediterranean and in Eastern Europe. The loss of species diversity would be less severe in Scandinavia and along the Atlantic. The scientists assessed the impact of various climate forecasts on 1350 European plant species. The climate forecasts assume an increase in carbon dioxide concentration in the atmosphere to up to twice today’s values and a rise in the average temperature of up to 4 degrees by 2080.
ALARM is one of five research projects with a total budget of 60 million euros, which the EU delegation presented at a meeting of the Biodiversity Convention in mid March 2006. Dr. Josef Settele from the UFZ is a member of the delegation and in Curitiba he reported on the content and interim results of the ALARM research project which he coordinates. The project focuses in particular on four areas which are thought to play a role in the loss of biological diversity: climate change, the loss of pollinators like bees, bumblebees and butterflies, harmful substances present in the environment and the invasion of non-native animal and plant species. The scientists work in over 40 different research regions spread across the whole of Europe and South America. By the end of the project in 2009, the project initiators expect fundamental advances in knowledge – in particular because of the unparalleled scale and complexity of the investigations.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
