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.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
