DNA research flies high with Seychelles kestrel

01.06.2004


A new research project at the University of Kent is looking for genetic evidence of a historical population bottleneck in the Seychelles kestrel by analysing DNA extracted from museum specimens estimated to be 100-150 years old.



Dr Jim Groombridge, Lecturer in Biodiversity Conservation at the University’s Durrell Institute of Conservation and Ecology, has been awarded £14,600 funding from The Royal Society to conduct population genetic research on oceanic island birds.

Museum collections throughout the UK, Europe and the US are contributing samples for DNA analysis from their preserved kestrel specimens, which were collected on the Seychelles by early Victorian naturalists. The aim is to interpret temporal changes in genetic variation in the Seychelles population alongside historical records of population size, to help improve our understanding of genetic bottlenecks in conservation biology.


Previous genetic work carried out on island kestrels in Mauritius and a broader survey of current genetic diversity in other kestrels shows that today’s Seychelles population is as genetically impoverished as the Mauritius kestrel, whose population has been successfully recovered from a single breeding pair in 1974. However, no such dramatic population history has been recorded on the Seychelles.

Im Focus: Freiburg researcher investigate the origins of surface texture

Most natural and artificial surfaces are rough: metals and even glasses that appear smooth to the naked eye can look like jagged mountain ranges under the microscope. There is currently no uniform theory about the origin of this roughness despite it being observed on all scales, from the atomic to the tectonic. Scientists suspect that the rough surface is formed by irreversible plastic deformation that occurs in many processes of mechanical machining of components such as milling.

Prof. Dr. Lars Pastewka from the Simulation group at the Department of Microsystems Engineering at the University of Freiburg and his team have simulated such...

Im Focus: Making the internet more energy efficient through systemic optimization

Researchers at Chalmers University of Technology, Sweden, recently completed a 5-year research project looking at how to make fibre optic communications systems more energy efficient. Among their proposals are smart, error-correcting data chip circuits, which they refined to be 10 times less energy consumptive. The project has yielded several scientific articles, in publications including Nature Communications.

Streaming films and music, scrolling through social media, and using cloud-based storage services are everyday activities now.

Im Focus: New synthesis methods enhance 3D chemical space for drug discovery

After helping develop a new approach for organic synthesis -- carbon-hydrogen functionalization -- scientists at Emory University are now showing how this approach may apply to drug discovery. Nature Catalysis published their most recent work -- a streamlined process for making a three-dimensional scaffold of keen interest to the pharmaceutical industry.

"Our tools open up whole new chemical space for potential drug targets," says Huw Davies, Emory professor of organic chemistry and senior author of the paper.
