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.”

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.

While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
