Ecologists help keep death off the roads

27.07.2004


Far fewer animals would be killed on the roads if planners took the findings of new research into account when designing and building new roads.

According to a study published today in the British Ecological Society’s Journal of Applied Ecology, it is possible to predict where most animals will attempt to cross roads, and hence where they are most likely to be killed by vehicles.

Researchers from Madrid University found that 70% of collisions occurred on just 7.7% of the roads in the area they studied. According to the authors: “Large animals such red deer, roe deer and wild boar are forest species, but their territory includes other habitats. Often they forage outside forest, especially when there are few people around. This then brings them into contact with roads, with disastrous consequences.”



The study found that collision black spots occur where animals find it easier to cross roads in the absence of human habitation. Fences or large, steep embankments deter animals from crossing roads and funnel animals to easy crossing points. At these points planners should install over- or underpasses for animals, the researchers say.

The need to consider the impact of roads on wildlife is emphasised in a second paper in the same issue of the Journal of Applied Ecology.

The Eurasian lynx is extremely rare in Germany and attempts at reintroduction are being made. Ecologists have found that conservationists need to reduce road mortality if such schemes are to be effective. Researchers from the UFZ Centre for Environmental Research found that the high density of roads in Germany means that many lynx are killed moving around the landscape.

According to the researchers: “The dense transport system results in high mortality. This gives clear management directives for dealing with reintroductions of lynx in Germany.”

Im Focus: Neutron star merger directly observed for the first time

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event

On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...

Im Focus: Cold molecules on collision course

Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.

How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...

Im Focus: Shrinking the proton again!

Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.

It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
