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

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: Radar for navigation support from autonomous flying drones

At the ILA Berlin, hall 4, booth 202, Fraunhofer FHR will present two radar sensors for navigation support of drones. The sensors are valuable components in the implementation of autonomous flying drones: they function as obstacle detectors to prevent collisions. Radar sensors also operate reliably in restricted visibility, e.g. in foggy or dusty conditions. Due to their ability to measure distances with high precision, the radar sensors can also be used as altimeters when other sources of information such as barometers or GPS are not available or cannot operate optimally.

Drones play an increasingly important role in the area of logistics and services. Well-known logistic companies place great hope in these compact, aerial...
