The Greater Noctule fossils found in the excavation site at Abríc Romaní (Barcelona) prove that this bat had a greater geographical presence more than 10,000 years ago than it does today, having declined due to the reduction in vegetation cover.
Although this research study, published in the journal Comptes Rendus Palevol, is the second to demonstrate the bat's presence in the Iberian Peninsula, it offers the first description in the fossil record of the teeth of Nyctalus lasiopterus from a fragment of the left jaw.
"It is an important finding because this species is not common in the fossil record. In fact, the discovery of Nyctalus lasiopterus at the Abríc Romaní site (Capellades, Barcelona) is one of the few cases of fossils existing on the species in the European Pleistocene", Juan Manuel López-García, principal author of the work and researcher at the Institute of Social Evolution and Human Palaeoecology at the Rovira i Virgili University (URV), tells SINC.
The analysis of the fossilised remains found at the site during the campaigns from 2004 to 2006 reveals that the largest bat in Europe inhabited north-eastern Spain more than 10,000 years ago. "Nyctalus lasiopterus is a fairly unknown species nowadays, with an indistinct geographical distribution in the peninsula, which does not include the region of Catalonia", adds López-García.
Distribution due to environmental factors
"The presence of Nyctalus lasiopterus in the north-eastern Iberian Peninsula strengthens the evidence that this species had a wider geographical range during the Pleistocene than today", says the palaeontologist. During the mild periods, when the development of vegetation gave these animals refuge, the Noctule had a wider territory.
Until now, the large bat had been located in mountainous regions such as the Eastern Pyrenees, the Cantabrian Mountains, the central mountain range or open Mediterranean landscapes where oaks, holm oaks and pines dominate.
However, the study confirms a change from the distribution of the species during the Late Pleistocene and the Holocene (less than 10,000 years ago) to now. "The reduction in vegetation cover could be the reason for the current low densities of the species and its biased geographical distribution", concluded López-García.

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.

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.
