Climate warming unlikely to cause near-term extinction of Amazon trees, but threats remainPublic release date: 13-Dec-2012 [ | E-mail | Share ]

ANN ARBOR A new genetic analysis has revealed that many Amazon tree species are likely to survive human-caused climate warming in the coming century, contrary to previous findings that temperature increases would cause them to die out.
However, the authors of the new study warn that extreme drought and forest fires will impact Amazonia as temperatures rise, and the over-exploitation of the region's resources continues to be a major threat to its future. Conservation policy for the Amazon should remain focused on reducing global greenhouse-gas emissions and preventing deforestation, they said.
The study by University of Michigan evolutionary biologist Christopher Dick and his colleagues demonstrates the surprising age of some Amazonian tree species more than 8 million years and thereby shows that they have survived previous periods as warm as many of the global warming scenarios forecast for the year 2100.
The paper is scheduled for online publication Dec. 13 in the journal Ecology and Evolution. The new study is at odds with earlier papers, based on ecological niche-modeling scenarios, which predicted tree species extinctions in response to relatively small increases in global average air temperatures.
"Our paper provides evidence that common Amazon tree species endured climates warmer than the present, implying that in the absence of other major environmental changes they could tolerate near-term future warming under climate change," said Dick, an associate professor of ecology and evolutionary biology and acting director of the U-M Herbarium.
But study co-author Simon Lewis of University College London and the University of Leeds cautioned that "the past cannot be compared directly with the future."
"While tree species seem likely to tolerate higher air temperatures than today, the Amazon forest is being converted for agriculture and mining, and what remains is being degraded by logging and increasingly fragmented by fields and roads," Lewis said. "Species will not move as freely in today's Amazon as they did in previous warm periods, when there was no human influence. Similarly, today's climate change is extremely fast, making comparisons with the past difficult.
"With a clearer understanding of the relative risks to the Amazon forest, we conclude that direct human impacts, such as forest clearance for agriculture or mining, should remain a focus of conservation policy," Lewis said. "We also need more aggressive action to reduce greenhouse gas emissions in order to minimize the risk of drought and fire impacts to secure the future of most Amazon tree species."
Dick and his colleagues used a molecular clock approach to determine the ages of 12 widespread Amazon tree species, including the kapok and the balsa. Then they looked at climatic events that have occurred since those tree species emerged. In general, they inferred that the older the age of the tree species, the warmer the climate it has previously survived.
The researchers determined that nine of the tree species have been around for at least 2.6 million years, seven have been present for at least 5.6 million years, and three have existed in the Amazon for more than 8 million years.
"These are surprisingly old ages," Dick said. "Previous studies have suggested that a majority of Amazon tree species may have originated during the Quaternary Period, from 2.6 million years ago to the present."
Air temperatures across Amazonia in the early Pliocene Epoch (3.6 million to 5 million years ago) were similar to Intergovernmental Panel on Climate Change projections for the region in 2100 using moderate carbon-emission scenarios. Air temperatures in the late Miocene Epoch (5.3 to 11.5 million years ago) were about the same as IPCC projections for the region in 2100 using the highest carbon-emission scenarios.
The 12 tree species used in the study are broadly representative of the Amazon tree flora. Primary forest collection sites were in central Panama, western Ecuador and Amazonian Ecuador. Additional collections were made in Brazil, Peru, French Guiana and Bolivia. Other plant samples were obtained from herbarium specimens.
"The most lasting finding of our study may be the discovery of ancient geographic variation within widespread species, indicating that many rain forest tree species were widely distributed before the major uplift of the northern Andes," said co-author Eldredge Bermingham of the Smithsonian Tropical Research Institute.
To determine the age of each tree species, the researchers extracted and sequenced DNA from plant samples, then looked at the number of genetic mutations contained in those sequences. Using a molecular clock approach and population genetic models, they estimated how long it would take for each of the tree populations to accumulate the observed number of mutations, which provided a minimum age for each species.
"An important caveat is that because we've been in a cold period over the past 2 million years basically the whole Quaternary Period some of the trees' adaptations to warmth tolerance may have been lost," Dick said. "Additional research is needed to test whether this has occurred."

The Ecology and Evolution paper is titled "Neogene origins and implied warmth tolerance of Amazon tree species." In addition to Dick, Bermingham and Lewis, Mark Maslin of University College London is a co-author. Financial support for the research was provided by the Smithsonian Tropical Research Institute, the University of Michigan, the National Science Foundation and the Royal Society.

TEHRAN, Iran (AP) ? A U.N. inspectors' team is in Tehran in a renewed effort to engage Iran and secure access to a site linked to suspected nuclear activity.
Iran's official IRNA news agency said Thursday the seven-member team ? headed by Herman Nackaerts, a deputy director general of the International Atomic Energy Agency ? would meet with Iranian nuclear officials.
The report says the two sides will try to reach a framework for restarting talks on Iran's nuclear program.
The IAEA has demanded for over a year to visit Parchin military site, which the agency says could have been used for experiments related to nuclear weapons. Iran insists the site is only a conventional military facility.
The West suspects Iran is trying to make a nuclear weapon. Tehran denies the charge.
Dec. 11, 2012 ? High-speed video of projectiles slamming into a bed of disks has given scientists a new microscopic picture of the way a meteorite or missile transfers the energy of its impact to sand and dirt grains.
The transfer is jerky, not smooth. "It was surprising just how unsmooth the slow-down of the intruding object was," Duke physicist Robert Behringer said. His team describes their new videos and impact analysis in the Dec. 7 Physical Review Letters. The research may change the way scientists model meteorite and missile impacts and their effects.
Scientists previously assumed that the slowing down would be smooth and that any sound wave would travel through a granular material in a regular, uniform pattern, similar to the way noise from a clap of the hands diffuses evenly in all directions through the air. But using high-speed video, Behringer, his graduate student Abram Clark and Lou Kondic of the New Jersey Institute of Technology have shown a very different behavior for the sound wave and grains during a collision.
In the study, supported by the Defense Threat Reduction Agency, the team shot bronze disks into a narrow bed of photoelastic grains and used an ultrafast camera to track the collision energy as it shifted from the disk to the beads. The footage shows that the bronze disk loses most of its energy in intense, sporadic acoustic pulses along networks of grains, or force chains, in the bed of beads.
"This phenomenon was so hard to observe before because of how fast the force chains travel," Behringer said. The standard movie rate is about 30 frames per second. To capture the path of energy down the force chains, the scientists had to use a camera that could capture 40,000 frames per second, 1300 times faster than a normal video, because the sound pulses move at such high speeds.
The scientists shot the intruding disks into the photoelastic grains at speeds up to 6.5 meters per second, about 15 miles per hour. On impact, the force chains in the disks started moving the energy away from the intruding object, dumping it down deep in the bed of disks like the drainpipes of a septic system carrying water and waste away from a house, Behringer said.
The speed of the bronze disk was well under sonic or super-sonic speed, which could make the patterns of energy transfer substantially different, the team noted in the paper. "For supersonic speeds, it's kind of like the car chases that happen in markets in movies. People can't get out of the way fast enough. Similarly the pulses wouldn't clear the chain networks and the forces would back up rather than get carried away from the intruder," Behringer said.
Studying the impacts at sonic and supersonic speeds, however, is a set of experiments that requires different grain particles, Behringer said, adding it's one the team may try soon. He also explained that once a missile or meteor drops below sonic speeds, the grains absorbing its impact would carry the energy and momentum away jerkily and sporadically, just as the team's new microscopic picture shows.
