Large structures for the rural extended family, small structures for the urban couple: European wild rabbits not only achieve high population densities in the city, their burrows are also built more densely and on a smaller external scale. That is something researchers in the Goethe University's Task Force on Ecology and Evolution have discovered in their study on wild rabbit populations in and around Frankfurt.
European wild rabbits (Oryctolagus cuniculus) not only achieve high population densities in the city, their burrows are also built more densely and on a smaller external scale. That is something researchers in the Goethe University's Task Force on Ecology and Evolution have discovered in their study on wild rabbit populations in and around Frankfurt.
As they report in the advance version of the Journal of Zoology, small burrow structures with fewer entrances and exits predominate in Frankfurt's inner city. These structures are inhabited by few animals - often only pairs or single wild rabbits. In contrast to this, the structural systems in the rural environs of Frankfurt are substantially larger and are also inhabited by larger social rabbit groups.
"The optimal habitat for a wild rabbit offers both, access to sufficient nourishment and the opportunity to establish rabbit burrows in very close proximity, or to seek out protective vegetation" explains doctoral candidate Madlen Ziege, a member of Prof. Bruno Streit's team. In rural, often agricultural used areas, with their cleared and open landscapes, these conditions are getting harder to find. Apparently, urban and suburban habitats satisfy the needs of wild rabbits far better.
In view of the fact that in some cities there is already talk of a "rabbit infestation", while in recent years the rabbit population in many rural areas of Germany has declined significantly, the scientists currently want to determine whether in the future urban populations could play a significant role as the source populations for the preservation of this wild animal species in Germany. They are therefore examining the population genetics or dynamics, their use of habitat and the state of health of rural, urban and suburban wild rabbit populations.

Goethe University is a research-oriented university in the European financial centre Frankfurt Founded in 1914 with purely private funds by liberally-oriented Frankfurt citizens, it is dedicated to research and education under the motto "Science for Society" and to this day continues to function as a "citizens’ university". Many of the early benefactors were Jewish. Over the past 100 years, Goethe University has done pioneering work in the social and sociological sciences, chemistry, quantum physics, brain research and labour law. It gained a unique level of autonomy on 1 January 2008 by returning to its historic roots as a privately funded university. Today, it is among the top ten in external funding and among the top three largest universities in Germany, with three clusters of excellence in medicine, life sciences and the humanities.

Strong light-matter coupling in these semiconducting tubes may hold the key to electrically pumped lasers
Light-matter quasi-particles can be generated electrically in semiconducting carbon nanotubes. Material scientists and physicists from Heidelberg University...
Fraunhofer IPA has developed a proximity sensor made from silicone and carbon nanotubes (CNT) which detects objects and determines their position. The materials and printing process used mean that the sensor is extremely flexible, economical and can be used for large surfaces. Industry and research partners can use and further develop this innovation straight away.
At first glance, the proximity sensor appears to be nothing special: a thin, elastic layer of silicone onto which black square surfaces are printed, but these...
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...
