Breaking down barriers – An appeal to conserve migratory ungulates in Mongolia´s grasslands

03.06.2014

Mongolian and international conservationists, including researchers from the Vetmeduni Vienna, have joined forces to raise awareness of the global importance of Mongolia´s steppes. The Gobi-Steppe Ecosystem is home to a unique diversity of animal and plant species, among them several large migratory mammals.

The scientists recommend reconciling the rapid infrastructure development that is currently taking place in Mongolia with the needs of migratory species, such as Asiatic wild ass and Mongolian gazelles. Their recommendations are published online in the journal Conservation Biology.

The Gobi-Steppe Ecosystem is world renowned for its populations of migratory ungulates, which cover great distances in search of forage. Researchers at the Research Institute of Wildlife Ecology at Vetmeduni Vienna have documented, that in just one year an individual wild ass can range over an area of 70,000 km2.

“Wild asses and gazelles have to be permanently on the move and travel very long distances to find enough food. Rainfall is highly variable in this region. As a consequence pastures are patchy and unpredictable in space and time,” explains Petra Kaczensky, one of the authors from the Vetmeduni Vienna.

Barriers to migration

Although vast stretches of land remain largely unaltered, migratory species face a number of obstacles that disrupt their journey and affect their ability to survive and reproduce in this highly variable environment. The main obstacles of the recent past are fences erected along the international borders with Russia and China and the Trans Mongolian Railroad.

The railroad fence now constitutes the de facto eastern border for the Asiatic wild ass, cutting the population off from its former much larger range to the east. Gazelles have also been largely restricted to either side of the railroad, but when they do attempt to cross they often get entangled or turned away. On its rapid path of economic development, Mongolia continues to build roads and new railway lines that are expected to threaten the ecological phenomenon of wildlife migration, if not carefully planned for.

Science can inform regional planning

Structural modifications could be made to fences, unnecessary fences could be removed in areas where there are no livestock, and planned railway lines could be re-routed to avoid sensitive areas. “We advocate a development process that minimizes negative effects on the integrity of the ecosystems such as following existing roads between villages to avoid large uninhabited regions while also incorporating the necessary designs so that they do not become new barriers; at the same time known barriers need to be removed,” says corresponding author Kirk Olson from Fauna & Flora International, a global conservation organization based in the UK. “Regional planners need to think big - meaning on the scale of the migrations,” adds author Nyamsuren Batsaikhaan from the National University of Mongolia.

A responsibility to link science and policy

Research into the movement and habitat requirements of the species roaming Mongolia´s Gobi-Steppe Ecosystem is ongoing, but needs to continue to identify potential conflicts between development efforts and biodiversity conservation requirements. Science can and should play a role in planning processes, according to Chris Walzer of the Vetmeduni Vienna, another author of the paper.

“It is also among the responsibilities of a university to provide that link between science and policy making. Scientists can provide constructive inputs in fields such as wildlife management and conservation,” Walzer emphasizes. “I think that if we do not translate our findings into practical advice that non-scientists can use, we have failed in our educational mission.” In the case of Mongolia, the authors are hopeful that joint efforts will lead to the preservation of the country´s outstanding natural heritage for future generations.

Im Focus: A “cosmic snake” reveals the structure of remote galaxies

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.

Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...

Im Focus: Visual intelligence is not the same as IQ

Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.

That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...

Im Focus: Novel Nano-CT device creates high-resolution 3D-X-rays of tiny velvet worm legs

Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.

During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....

Im Focus: Researchers Develop Data Bus for Quantum Computer

The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.

Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
