Published online today in the Ecological Society of America’s journal Frontiers in Ecology and the Environment, the review concludes we are “on a trajectory towards disaster” and calls for an immediate global, multi-pronged conservation approach to avert the worst outcomes.
Lead author Associate Professor Corey Bradshaw, from the University of Adelaide’s School of Earth and Environmental Sciences, says tropical forests support more than 60% of all known species. But up to 15 million hectares of tropical rainforest are being lost every year and species are being lost at a rate of up to 10,000 times higher than would happen randomly without humans present.
“This is not just a tragedy for tropical biodiversity, this is a crisis that will directly affect human livelihoods,” says Associate Professor Bradshaw. “This is not just about losing tiny species found at the base of big trees in a rain forest few people will ever see, this is about a complete change in ecosystem services that directly benefit human life.
“The majority of the world’s population live in the tropics and what is at stake is the survival of species that pollinate most of the world’s food crops, purify our water systems, attenuate severe flood risk, sequester carbon (taking carbon dioxide out of the air) and modify climate.”
Associate Professor Bradshaw says recent technical debate about likely extinction rates in the tropics could be used by governments to justify destructive policies.
“We must not accept belief that all is well in the tropics, or that the situation will improve with economic development, nor use this as an excuse for inaction on the vexing conservation challenges of this century,” he says.
“We need to start valuing forests for all the services they provide, and richer nations should be investing in the maintenance of tropical habitats.”
One of the biggest issues is corruption. “The greatest long-term improvements can be made in governance of tropical diversity resources and good governance will only come from strong multi-lateral policy. We need international pressure to ensure appropriate monitoring and accounting systems are in place,” says Associate Professor Bradshaw.

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...
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...
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....
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,...
