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.

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...

'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
