The study shows that olive groves with low production close to the Natural Park of the Sierra de Cardeña y Montoro, in Córdoba – which is the only place, along with Doñana, where this species lives – are the most appropriate sites for this purpose.
Researchers from the regional government of Andalusia's Institute for Agricultural and Fishing Research and Training (IFAPA) have studied the impact and risk of these mountain olive groves being abandoned, in order to come up with an appropriate management system for them (conventional, mixed or organic), or to suggest they should be reconverted to Mediterranean forest.
The risk of these olive groves being abandoned is "due to their location, which has serious socioeconomic implications (mainly in terms of the population leaving rural areas) and environmental ones (erosion and risk of fires)", Manuel Arriaza, director of the study and a researcher at the IFAPA, tells SINC. "Although the olive groves have low production levels and high production costs, they are areas with great environmental value", adds Arriaza.
The results suggest that the most highly-valued function of mountain olive groves is their ability to retain the rural population (24%), followed by production of olive oil (17%) and the prevention of erosion (16%).
On the basis of the interviews and the geographical features of the area, the model's final proposal suggests that 36% of the land should be planted to conventional olive groves, 23% should be reconverted to Mediterranean forest, 22% should be mixed olives and forest, and 19% organic olive groves.
However, once the best areas for restoration of Iberian lynx habitat have been generically identified, "other aspects not covered by the initial land analysis should also be looked at before any action is taken, such as the size of the rabbit population present, or fragmentation of certain areas", points out Arriaza.

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.
To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...
Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
