Wild And Homebody Species

12.12.2005


Two field-vole species, which are outwardly indistinguishable, behave differently towards human beings. Results of experiments carried out by the specialists of the Institute of Ecology and Evolution Problems, Russian Academy of Sciences, and the Lomonosov Moscow State University connect these differences with the exploratory behavior of field-voles. Timorous and incurious common voles (Microtus arvalis) prefers country life, and inquisitive European ground voles (Arvicola terrestris) readily move into human lodgings.



To investigate field-voles’ behavior, the researchers constructed a case (its side being equal to 4 meters) imitating a living room. There was a can, a bottle, small boxes, shoes, a shelter, feeding-racks and a drinking bowl, a tray with a flower, chairs, suitcase, a camp-bed with a pillow and a bedside-table in it. The field-voles involed in the experiment were born in captivity. Their belonging to a certain species was confirmed with the help of haemoglobin analysis. The small animals were carried into the room in the shelter, which previously used to stand in its dwelling cage, and were observed for two hours after the animal had left the shelter.

This observational study found that the common voles dislike and are afraid of new things. The level of investigation activity of the European ground voles is higher than that of their twin-species and is more intelligent. Such a strategy, of investigating unfamiliar space, allowed them to accomodate themselves to life near to human beings and to settle in town and in the country. They willingly feel at home in unknown closed premises, including human houses where they wait through winter cold weather. Therefore, the researchers consider the European ground vole to be a synanthropic species, and the common vole – rather wild species.

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...
