Ray of Hope for Vultures Facing Extinction

31.01.2006


Today saw a glimmer of hope for the three species of Asian vulture threatened with extinction.



Oriental white-backed, long-billed, and slender-billed vultures in South Asia have suffered one of the most rapid and widespread population declines of any bird species, declining by more than 97% over the last 10-15 years.

These declines were caused by the widespread veterinary use of the drug diclofenac for the treatment of sick domestic livestock throughout the Indian subcontinent. Diclofenac kills vultures that feed on the bodies of livestock that have been given the drug shortly before death.


To combat diclofenac’s devastating effects on vulture populations, the Indian government announced, in March 2005, its intention to phase out the use of the drug. However, progress has been hampered by the lack of an alternative drug that is known to be safe for vultures yet effective for treating livestock.

In a new report published in the open access journal PLoS Biology, a team of scientists from South Africa, Namibia, India, and the UK concluded that such an alternative has now been found.

The team, led by Gerry Swan of the University of Pretoria, found that the drug meloxicam was safe to vultures at the likely range of levels they would be exposed to in the wild. Meloxicam, which is similar to diclofenac in its effectiveness for treating livestock, has recently become available for veterinary use in India and could easily be used in place of diclofenac.

“This research is an excellent example of international collaboration in response to an urgent conservation problem,” Said Dr Debbie Pain, Head of International Research at the RSPB and a co-author of the paper.

Fellow-author Dr Rhys Green, Principal Research Biologist at the RSPB and a scientist at Cambridge University, said: “Dr Lindsay Oaks discovered that diclofenac is the cause of the vulture declines just two years ago, so having found a practical solution so quickly is encouraging. Even so, vulture populations are declining so fast that it could still be too late to save them unless action is taken immediately.”

Publication of these results is very timely because the government of India today convened a two-day international meeting to decide how to save the endangered vultures. Removal of diclofenac from their food supply is a vital step, so the identification of an alternative drug may have come just in time.

Dr Asad Rahmani, Director of the Bombay Natural History Society said: “It is essential that the government of India acts quickly to make good use of this new information. Diclofenac must be replaced by meloxicam as soon as possible and there are many things that government can do to speed this up.”

The vulture declines have had profound ecological and social consequences. Vultures play a vital role in environmental health by disposing of carcasses and reducing the risk of disease.

The two key steps necessary to save vultures from extinction are removal of diclofenac from their food chain, and the establishment of conservation centres for captive breeding as a stop-gap measure until that is achieved.

“It is essential that the environment is free of diclofenac before vultures from conservation breeding centres can be released into the wild,” said RSPB Research Biologist Dr Richard Cuthbert, who coordinated the new research. “In view of these findings, there is now no reason for governments to delay in banning the veterinary use of diclofenac.”

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
