For good or ill Ireland gains another mammal species

29.04.2008
A recent study, soon to be published in Mammal Review, details the discovery of a mammal which has never been seen before in Ireland. The shrew, which has been spotted in Tipperary and Limerick, is only the third new mammal to be found on the island in almost 60 years.

Dave Tosh, from the School of Biological Sciences at Queens University, found the greater white-toothed shrew in Tipperary and Limerick while working with University College Cork and BirdWatch Ireland. Its natural range is in parts of Africa, France and Germany and before now the closest it has been spotted to Ireland is in the Channel Islands.

As part of his PhD, Dave was studying the diet of the Barn Owl in Ireland. Last winter John Lusby, Barn Owl Research Officer from Bird Watch Ireland, sent him pellets (regurgitated food remains) from owls in Tipperary and Limerick to help with the study.

Dave explained: “It was amongst a batch that I was about to dry in an oven, that I noticed a very large shrew skull.

“Having looked at hundreds of pellets from Ireland already I knew that what I was looking at was very unusual as our native pygmy shrew is very small in comparison.

“I ended up looking through more and more pellets and discovered more and more of the strange shrew skulls.”

In March seven greater white-toothed shrews were trapped at four locations in Tipperary and their existence has just been recorded in the scientific journal Mammal Review.

Professor Ian Montgomery, Head of the School of Biological Sciences at Queen’s, says the animal is likely to have been introduced recently to Ireland and the discovery of a new mammal species in Ireland is extremely rare.

“Most species which occur in Ireland also occur in Britain but the nearest this species of shrew has been found is on the Channel Islands and the Scilly Isles.

“These records are evidence of at least one recent introduction event, probably accidental, from continental Europe to Ireland and has resulted in a rapid increase in numbers over a short period.”

The discovery, however, raises issues related to ecological impact and control which need to be further researched. While the shrew is likely to sustain threatened birds of prey including the barn owl, it could lead to the loss of small native mammals including the pygmy shrew.

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
