The world’s first bat net for migrating bats is launched in Latvia

19.08.2014

The worldwide largest funnel trap designed for the purpose of studying migratory bats will opened at the ornithological field station in Pape, Latvia, on August 19, 2014. At the same time, an ambitious international research project on the biology of migratory bats will be started. The project is expected to provide some key answers to many unsolved questions concerning flight paths, hibernation areas and metabolism of these ecologically valuable mammals.

The trap was built by Latvian and German biologists and designed to capture bats en route when migrating along the shore of the Baltic sea to central and southwestern Europe. The research project is part of a collaboration between the German Leibniz Institute for Zoo and Wildlife Research (IZW) and the Institute of Biology of the Latvian University of Agriculture.

“Owing to decades of bird banding, ornithologists already know much about the migration of birds. However, the study of bat migration is still in its infancy. This is due to the fact that there are very few places worldwide where it is possible to observe and catch migrating bats in sufficient numbers.

The conservation area in Pape is unique in this regard, as bats concentrate in this area because of a so-called ‘bottleneck effect’. In Pape, the migration path towards the south is narrowed in a natural way by the shoreline of the Baltic Sea and Lake Pape. Therefore, migrating bats have to pass this narrow stretch of land. There is no other place in Europe to observe so many migrating bats at the same time”, states bat scientist Gunārs Pētersons, associate professor at the Latvian University for Agriculture.

Biologists estimate that with the help of the new 15 meter high funnel trap it will be possible to catch up to 1,000 bats per night. The researchers will ring as many animals as possible in order to figure out which migratory corridor they use.

All animals will be released immediately after they were banded. Previous efforts in banding bats at Pape in the 1980s and 1990s revealed that bats may travel distances of more than 1,900 km between their summer and hibernation areas. For example, some Nathusius pipistrelles, which had been ringed in Pape, were observed in southern France or Benelux countries.

The trap will help scientists to answer further questions about the life of migrating bats. It is for example unknown whether migrating bats use special migration corridors, or which summer and hibernation areas are linked. This infomation could contribute to the improved conservation of migrating bats.

Migrating bats face many conservation challenges, including the negotiation of the many new wind farms set up in Germany and many other European countries. Wind turbines are deadly traps for many wildlife speices, especially migrating bats.

Approximatly 300,000 bats are currently estimated to die per year at German wind turbines alone. Mitigation measures that balance the interests of renewable energy generation with protecting migrating bats are possible in principle and revolve around the adjustment of operational procedures in relation to the timing of main bat activity on a daily and seasonal level.

The new funnel trap in Pape will be officially inaugurated by the director of the Institute for Biology of the Latvian University of Agriculture, Prof Dr Viesturs Melecis and the director of the Leibniz Institute for Zoo and Wildlife Research (IZW), Prof Dr Heribert Hofer DPhil, as well as the leading Latvian and German scientists Prof Dr Gunārs Pētersons and PD Dr Christian Voigt. The opening event will take place on August 19, 2014 at the ornithological field station in Pape (region Rucava, Latvia).

The Leibniz Institute for Zoo and Wildlife Research (IZW) investigates the vitality and adaptability of wildlife populations in mammalian and avian species of outstanding ecological interest that face anthropogenic challenges. It studies the adaptive value of traits in the life cycle of wildlife, wildlife diseases and clarifies the biological basis and development of methods for the protection of threatened species. Such knowledge is a precondition for a scientifically based approach to conservation and for the development of concepts for the ecologically sustainable use of natural resources.

Im Focus: Computational high-throughput screening finds hard magnets containing less rare earth elements

Permanent magnets are very important for technologies of the future like electromobility and renewable energy, and rare earth elements (REE) are necessary for their manufacture. The Fraunhofer Institute for Mechanics of Materials IWM in Freiburg, Germany, has now succeeded in identifying promising approaches and materials for new permanent magnets through use of an in-house simulation process based on high-throughput screening (HTS). The team was able to improve magnetic properties this way and at the same time replaced REE with elements that are less expensive and readily available. The results were published in the online technical journal “Scientific Reports”.

The starting point for IWM researchers Wolfgang Körner, Georg Krugel, and Christian Elsässer was a neodymium-iron-nitrogen compound based on a type of...

Im Focus: Atomic precision: technologies for the next-but-one generation of microchips

In the Beyond EUV project, the Fraunhofer Institutes for Laser Technology ILT in Aachen and for Applied Optics and Precision Engineering IOF in Jena are developing key technologies for the manufacture of a new generation of microchips using EUV radiation at a wavelength of 6.7 nm. The resulting structures are barely thicker than single atoms, and they make it possible to produce extremely integrated circuits for such items as wearables or mind-controlled prosthetic limbs.

In 1965 Gordon Moore formulated the law that came to be named after him, which states that the complexity of integrated circuits doubles every one to two...
