Could your pond offer a home to the crays?

13.08.2008
Scientists at the University of Leeds are on the look out for willing volunteers who could provide a home for a dying breed of aquatic invertebrates.

The white-clawed crayfish is native to British waters and scientists believe it plays a vital role in preserving the natural biodiversity of our inland waters. Researchers from the University of Leeds now need to find several large ponds into which the animal can be introduced and then study the effect their presence has over several months.

Neal Haddaway, a PhD student at the Faculty of Biological Sciences says; “This is a great opportunity to take part in a unique backyard conservation project. Our studies will help us understand the role this creature plays in keeping water clean, keeping the numbers of unwelcome pests down and generally managing local ecosystems. Volunteers who offer up the use of their ponds will be making a real difference to a British conservation project.”

Declining numbers of the crayfish are found in the several areas of Yorkshire including the Wharfe, Upper Aire, Upper Ure, Swale and some streams to the north of Leeds. In the 1970’s new species were introduced to these waters in the hope of enhancing food supplies for fish but the American signal crayfish eat vast quantities of snails and mayfly larvae, disrupting the existing food-chain. In addition to being more predatory in this way, they also brought with them a plague that has devastated the local population. The white-clawed crayfish now faces extinction if researchers fail to find a way to save it.

Dr Alison Dunn says; “We believe that these creatures play a fundamental part in maintaining the ecosystems contained within our streams and rivers, if the white crayfish are lost then plant and animal biodiversity could be badly affected. It could become extinct within the next ten years if we do not act now. ”

Neal Haddaway is hoping to find ponds in gardens and on farms that already have some wildlife in them and do not have a plastic lining. The ponds need to be between two to five metres across, but less than 15 metres and be at least five years old. After the white-clawed crayfish have been introduced then the pond-life and water quality will be tested on a regular basis for any changes that seem to occur as a result of their being there.

Anyone who is interested in taking part in this project can contact Neal by emailing crayfish.science@googlemail.com

Im Focus: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Im Focus: Tracing down linear ubiquitination

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.

Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Im Focus: Researchers Imitate Molecular Crowding in Cells

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
