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.

In a recent publication in the renowned journal Optica, scientists of Leibniz-Institute of Photonic Technology (Leibniz IPHT) in Jena showed that they can accurately control the optical properties of liquid-core fiber lasers and therefore their spectral band width by temperature and pressure tuning.
Already last year, the researchers provided experimental proof of a new dynamic of hybrid solitons– temporally and spectrally stationary light waves resulting...

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.
Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...
The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.
Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.
An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.
