Are rainforests as natural as they appear? How best to replant large forest areas destroyed by fire? A new consultancy service providing the data needed to answer these and other questions has been established at the University of Oxford.
BioGeoSciences for Conservation (BGSC) has been set up to help managers having to make those decisions by providing information about how environments have evolved over long timescales. The consultancy service is backed by a specialist laboratory which uses fossil records such as pollen and charcoal to reconstruct how forests, savannas and other areas developed in response to changes in climate, disturbances by fire and people, and changes in soil fertility and water availability over hundreds to thousands of years.
Dr Kathy Willis, one of three Principals of BGSC, also heads the Oxford Long-term Ecology Laboratory. She said: ‘What is unique about this service is the way in which it links together many techniques to provide information that is not normally accessible to those involved in environmental management who tend to base their decisions simply on knowledge of current ecological patterns. We take a long-term perspective, sometimes over thousands of years, to help manage biodiversity today.

In a joint experimental and theoretical work performed at the Heidelberg Max Planck Institute for Nuclear Physics, an international team of physicists detected for the first time an orbital crossing in the highly charged ion Pr⁹⁺. Optical spectra were recorded employing an electron beam ion trap and analysed with the aid of atomic structure calculations. A proposed nHz-wide transition has been identified and its energy was determined with high precision. Theory predicts a very high sensitivity to new physics and extremely low susceptibility to external perturbations for this “clock line” making it a unique candidate for proposed precision studies.
Laser spectroscopy of neutral atoms and singly charged ions has reached astonishing precision by merit of a chain of technological advances during the past...
The ability to investigate the dynamics of single particle at the nano-scale and femtosecond level remained an unfathomed dream for years. It was not until the dawn of the 21st century that nanotechnology and femtoscience gradually merged together and the first ultrafast microscopy of individual quantum dots (QDs) and molecules was accomplished.
Ultrafast microscopy studies entirely rely on detecting nanoparticles or single molecules with luminescence techniques, which require efficient emitters to...
Graphene, a two-dimensional structure made of carbon, is a material with excellent mechanical, electronic and optical properties. However, it did not seem suitable for magnetic applications. Together with international partners, Empa researchers have now succeeded in synthesizing a unique nanographene predicted in the 1970s, which conclusively demonstrates that carbon in very specific forms has magnetic properties that could permit future spintronic applications. The results have just been published in the renowned journal Nature Nanotechnology.
Depending on the shape and orientation of their edges, graphene nanostructures (also known as nanographenes) can have very different properties – for example,...
