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.

A new manufacturing technique uses a process similar to newspaper printing to form smoother and more flexible metals for making ultrafast electronic devices.
The low-cost process, developed by Purdue University researchers, combines tools already used in industry for manufacturing metals on a large scale, but uses...
For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
