The largest bat in Europe inhabited northeastern Spain more than 10,000 years ago

02.11.2009
Spanish researchers have confirmed that the largest bat in Europe, Nyctalus lasiopterus, was present in north-eastern Spain during the Late Pleistocene (between 120,000 and 10,000 years ago).

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.

Im Focus: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
