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: Goodbye, silicon? On the way to new electronic materials with metal-organic networks

Scientists at the Max Planck Institute for Polymer Research (MPI-P) in Mainz (Germany) together with scientists from Dresden, Leipzig, Sofia (Bulgaria) and Madrid (Spain) have now developed and characterized a novel, metal-organic material which displays electrical properties mimicking those of highly crystalline silicon. The material which can easily be fabricated at room temperature could serve as a replacement for expensive conventional inorganic materials used in optoelectronics.

Silicon, a so called semiconductor, is currently widely employed for the development of components such as solar cells, LEDs or computer chips. High purity...

Storage of highly volatile gases has always been a major technological challenge, not least for use in the automotive sector, for, for example, methane or...

Im Focus: Disrupting crystalline order to restore superfluidity

When we put water in a freezer, water molecules crystallize and form ice. This change from one phase of matter to another is called a phase transition. While this transition, and countless others that occur in nature, typically takes place at the same fixed conditions, such as the freezing point, one can ask how it can be influenced in a controlled way.

We are all familiar with such control of the freezing transition, as it is an essential ingredient in the art of making a sorbet or a slushy. To make a cold...
