Antarctic Treaty meeting moves to protect frozen continent from non-native species

29.06.2006
Important new measures to protect Antarctica – the world’s last great wilderness – from invasive non-native species have been agreed at a meeting of Antarctic experts in Edinburgh.

Scientists and policy makers at the Antarctic Treaty Consultative Meeting, which finished at Edinburgh International Conference Centre on Friday 23 June, agreed new measures that will reduce the risk of non-native species being introduced into both marine and terrestrial ecosystems in Antarctica.

To protect the marine environment, the meeting adopted new practical guidelines for ballast water exchange by ships operating in the Southern Ocean around Antarctica. Under the new guidelines drawn up by the UK, vessels will need to exchange any ballast water before arriving in Antarctic waters, and plan for and keep records of all ballast water operations.

According to Dr John Shears of British Antarctic Survey, “In the past, Antarctica was isolated with a very harsh and cold environment, which made it very difficult for non-native species to establish. However, more and more people are travelling to the continent, most of them on ships. Evidence from other parts of the world has shown that there is a direct link between numbers of people visiting a remote area and the numbers of non-native species that survive. Once established, they can be very difficult to eradicate. Prevention is better than cure.”

Concerned that a rapidly changing and warming climate on the Antarctic Peninsula could increase the risk of non-native species establishing themselves on the continent itself, the meeting also backed a series of recommendations made by New Zealand. These include development of a code of conduct for land-based activities - a set of minimum standards that all visitors, including tourists and scientists, would have to follow. Scientists called for more research into the issue. Dr Shears said that scientists need to identify which areas of Antarctica are most vulnerable and better understand the potential implications of climate change on the spread of non-native species.

Dr Shears says, “Antarctica’s remoteness and isolation offer science a unique opportunity to understand our world. Part of Antarctica’s value as a natural laboratory lies in the fact that its communities of animals and plants consist of only a few species living in simple relationships. This makes the Antarctic a perfect place to study how ecosystems work. The inadvertent introduction of non-native species into Antarctica could put this in jeopardy, and has the potential to change the continent’s biodiversity forever.”

Im Focus: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".

Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
