Swedish pasturelands save Europe's butterflies

Herb-rich pasturelands in Sweden's woodland areas display a wealth of butterfly species that are dwindling in many other countries in Western Europe, according to a study from Linköping University in Sweden. But with the growing introduction of more efficient agricultural production, Sweden risks going down the same path.

In the latest issue of the journal Biodiversity and Conservation, Karl-Olof Bergman, a researcher in conservation biology, and his colleagues publish the results of a comprehensive study of 60 pasturelands in Östergötland in Sweden. They turned out to be a haven for a number of species that are growing more and more rare in countries like Germany, the U.K., and Belgium.

The heath fritillary (Melitaea athalia), for example, is found in all locales in the Swedish study, whereas it has completely disappeared from Belgian Flanders and has declined dramatically in both western Germany and the U.K. The high brown fritillary (Argynnis adippe) can be found in 65 percent of the Östergötland pastures but has virtually disappeared from the other countries.

The pasturelands under study are 3-8 hectares in size, with deciduous tree growth and surrounded by conifers. This is a type of biotope that is receding in the rest of Western Europe. If efficiency measures in Swedish agriculture continue at today's rate, there is a danger that the same development will take place in Sweden as well. The greatest danger is the decline in small farms with grazing animals.

"Sweden has a tremendous responsibility to conserve these species and environments. If the trend is not halted, Europe runs the risk of losing some of its most diverse biotopes," says Karl-Olof Bergman.

The study, which was carried out on five occasions from May to September 2004, found 17,153 butterflies of 64 different species.

The article "Importance of boreal grasslands in Sweden for butterfly diversity and effects of local and landscape habitat factors" by Karl-Olof Bergman, Lena Ask, John Askling, Håkan Ignell, Henrik Wahlman, and Per Milberg is published in the online version of Biodiversity and Conservation.

Im Focus: Etching Microstructures with Lasers

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.

This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Terahertz excitation of selected crystal vibrations leads to an effective magnetic field that drives coherent spin motion

Controlling functional properties by light is one of the grand goals in modern condensed matter physics and materials science. A new study now demonstrates how...

Im Focus: New 3-D wiring technique brings scalable quantum computers closer to reality

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.

"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...

Im Focus: Scientists develop a semiconductor nanocomposite material that moves in response to light

In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.

"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
