New Study To Investigate Demise Of Coral Reef Ecosystems

02.08.2004


Scientists are embarking on a project which will explore how global warming is devastating one of the world’s most diverse ecosystems.



One sixth of the world’s coral reefs died due to bleaching in 1998, and the situation is getting worse. Bleaching occurs when tropical seas heat up above there normal maximums, killing the corals.

These events are equally catastrophic for the quarter of all known marine species which make their home in the reefs and for the coastal communities which depend on them for their livelihoods.


Scientists at the University of Newcastle upon Tyne in the UK will lead the new project, which is funded by the Leverhulme Trust. They will collaborate with colleagues in the World Conservation Society and others in the West Indian Ocean region and the Australian Institute of Marine Science on the Great Barrier Reef.

Coral reefs cover around 300,000 square kilometres worldwide. The research team will examine the ecosystem consequences of bleaching, particularly on reef fish assemblages over five to 15 year time scales at sites in the Western Indian Ocean (including the Seychelles, Kenya and Sri Lanka), and Australia.

The project will conclude with a large-scale analysis of results in order to gauge changes occurring across whole regions as a result of substantial bleaching events. It will be one of the only studies to look at the effects of bleaching over the medium to long-term and the first at such large scale.

Project leader, Dr Nicholas Polunin, of Newcastle University’s School of Marine Science and Technology, said: “Coral bleaching is predicted to increase in frequency in the coming decades and a recent investigation at one location in Papua New Guinea has indicated that this may have very great impacts on associated fishes and thus the wider reef ecosystem.

“This study will assess whether or not this holds across two major coral reef regions of the globe, with clear implications for the future of one of the world’s most biodiverse ecosystems.”

Im Focus: Abrupt motion sharpens x-ray pulses

Spectrally narrow x-ray pulses may be “sharpened” by purely mechanical means. This sounds surprisingly, but a team of theoretical and experimental physicists developed and realized such a method. It is based on fast motions, precisely synchronized with the pulses, of a target interacting with the x-ray light. Thereby, photons are redistributed within the x-ray pulse to the desired spectral region.

A team of theoretical physicists from the MPI for Nuclear Physics (MPIK) in Heidelberg has developed a novel method to intensify the spectrally broad x-ray...

Im Focus: Physicists Design Ultrafocused Pulses

Physicists working with researcher Oriol Romero-Isart devised a new simple scheme to theoretically generate arbitrarily short and focused electromagnetic fields. This new tool could be used for precise sensing and in microscopy.

Microwaves, heat radiation, light and X-radiation are examples for electromagnetic waves. Many applications require to focus the electromagnetic fields to...

Im Focus: Carbon Nanotubes Turn Electrical Current into Light-emitting Quasi-particles

Strong light-matter coupling in these semiconducting tubes may hold the key to electrically pumped lasers

Light-matter quasi-particles can be generated electrically in semiconducting carbon nanotubes. Material scientists and physicists from Heidelberg University...

Im Focus: Flexible proximity sensor creates smart surfaces

Fraunhofer IPA has developed a proximity sensor made from silicone and carbon nanotubes (CNT) which detects objects and determines their position. The materials and printing process used mean that the sensor is extremely flexible, economical and can be used for large surfaces. Industry and research partners can use and further develop this innovation straight away.

At first glance, the proximity sensor appears to be nothing special: a thin, elastic layer of silicone onto which black square surfaces are printed, but these...
