Protected areas save mangroves, reduce carbon emissions

CO2 in sediments is released when mangroves destroyed


2015-09-14
(Press-News.org) DURHAM, N.C. -- Protected areas not only keep significant swaths of Indonesia's shrinking mangrove habitats intact, but also prevent emissions of carbon dioxide that would have been released had these mangroves been cleared, according to a study in the journal Ecological Economics.

Published online, the analysis examined the success of protected areas between 2000 and 2010, finding that their use has avoided the loss of 14,000 hectares of mangrove habitat.

"This is not a small number," said Daniela Miteva, a postdoctoral researcher at The Nature Conservancy and a Duke University alumna. "Protected areas have reduced the rate of mangrove loss by about 28 percent in Indonesia, which has the world's largest area of mangroves."

Mangroves are dense forests of trees and shrubs that grow in brackish, low-lying coastal areas in the tropics and subtropics. The study is the first rigorous large-scale evaluation of the effectiveness of protected areas in reducing mangrove loss and carbon dioxide emissions, using a detailed country-wide data set of social, economic, climatic, geographic, biophysical and environmental indicators.

"We found that by keeping more mangroves intact we avoided release of approximately 13 million metric tons of carbon dioxide into the atmosphere," said Brian Murray, co-author and director of the Environmental Economics Program at Duke's Nicholas Institute for Environmental Policy Solutions. "That's equivalent to taking 344,000 vehicles off the road each year."

This carbon dioxide is released mainly through the disturbance of carbon stored in sediment layers beneath mangroves, referred to as "blue carbon." When the water around mangroves is drained or they are destroyed, the sediment layers below begin to oxidize. Once this soil, which can be many meters deep, is exposed to air or ocean water, it releases carbon dioxide.

"Our study suggests that the mangrove conservation in Indonesia generated approximately $540 million in social welfare benefits from avoided climate change damages," said Subhrendu Pattanayak, professor of public policy and environmental economics at Duke's Sanford School of Public Policy and the Nicholas School of the Environment.

"Our study is one the few rigorous and careful attempts to see if conservation policies work," Pattanayak said. "We find that while designated protected marine areas do the job, there is no evidence that certain other, less-specific forms of species protection stalled the loss of mangroves, suggesting we need a new approach that distinguishes between types of protected areas. A one-size fits all solution is a poor policy."

It's time to stop thinking in terms of food versus fuel

Its time to stop thinking in terms of food versus fuel
2015-09-14
Whether you have taken a side or a backseat in the discussion, the "food versus fuel" debate affects us all. Some say growing more biofuel crops today will decrease greenhouse gas emissions, but will make it harder to produce food tomorrow, which has prevented the U.S. from maximizing the potential of environmentally beneficial biofuels. In a recent article, published by the National Academy of Engineering, University of Illinois' Gutgsell Endowed Chair of Plant Biology and Crop Sciences Steve Long and University of California's Philomathia Professor of Alternative Energy ...

Tall and slim: They go together, genetic study shows

2015-09-14
University of Queensland scientists have found a genetic basis for height and body mass differences between European populations. Queensland Brain Institute researcher Dr Matthew Robinson said the findings could explain why people from northern European countries tended on average to be taller and slimmer than other Europeans. He said the genes that resulted in greater height correlated strongly with genes that reduced body mass index. "Our findings give a genetic basis to the stereotype of Scandinavians as being tall and lean," Dr Robinson said. The study paves ...

Findings could shed light on cancer, aging

2015-09-14
Researchers at the Johns Hopkins University have found molecular evidence of how a biochemical process controls the lengths of protective chromosome tips, a potentially significant step in ultimately understanding cancer growth and aging. In a paper recently published as the cover story in the online journal eLife, biologist David C. Zappulla and graduate student Evan P. Hass show how in baker's yeast cells, two proteins work together to usher a key enzyme to the chromosome tip, the telomere, to restore its length, which diminishes with each round of cell division. That ...

Size matters -- the more DNA the better

2015-09-14
A new study from researchers at Uppsala University shows that variation in genome size may be much more important than previously believed. It is clear that, at least sometimes, a large genome is a good genome. 'Our study shows that females with larger genome lay more eggs and males with larger genome fertilize more eggs', says research leader Göran Arnqvist, Professor of Animal Ecology at Uppsala University. The study of seed beetles is published in the scientific journal Proceedings of the Royal Society of London. The amount of nuclear DNA per cell, or the ...

AHA's 'Life's Simple 7' and diabetes care program reduce risk of heart failure

2015-09-14
Philadelphia, PA, September 14, 2015 - One in four middle-aged adults who survive to age 85 will develop heart failure, according to current estimates. Intervention programs to improve lifestyles are widely advocated, but do they actually work? Investigators in the U.S. and Taiwan independently examined programs that may reduce cardiovascular risk and concluded that both programs will reduce lifetime risk of heart failure. Results are reported in The American Journal of Medicine. A group of American investigators estimated whether greater adherence to the American Heart ...

Three new studies converge on promising new target for addiction treatment

2015-09-14
Philadelphia, PA, September 14, 2015 - The latest issue of Biological Psychiatry presents the results of three studies implicating metabotropic glutamate receptor 2 (mGluR2) as a new molecular target for the treatment of addiction. Group II metabotropic glutamate receptors, which include the subtypes mGluR2 and mGluR3, have been known targets for addiction treatment. Unfortunately, mGluR2/3 agonists studied to date have shown important limitations, including development of tolerance and decreasing food intake along with drug intake. Thus, scientists have been working ...

Optogenetics: Light switch generates cellular second messenger

2015-09-14
This news release is available in German. FRANKFURT. Optogenetics is a quickly expanding field of research which has revolutionized neurobiological and cellbiological research around the world. It uses natural or tailored light-sensitive proteins in order to switch nerve cells on and off without electrodes with unprecedented accuracy in respect to time and location. The discovery of the light-gated ion channel channelrhodopsin in algae in 2002 was a key finding for this field. In 2005, Frankfurt scientists working with Prof. Alexander Gottschalk succeeded in transferring ...

You're not irrational, you're just quantum probabilistic

2015-09-14
COLUMBUS, Ohio--The next time someone accuses you of making an irrational decision, just explain that you're obeying the laws of quantum physics. A new trend taking shape in psychological science not only uses quantum physics to explain humans' (sometimes) paradoxical thinking, but may also help researchers resolve certain contradictions among the results of previous psychological studies. According to Zheng Joyce Wang and others who try to model our decision-making processes mathematically, the equations and axioms that most closely match human behavior may be ones ...

World's turtles face plastic deluge danger

Worlds turtles face plastic deluge danger
2015-09-14
An international study led by a University of Queensland researcher has revealed more than half the world's sea turtles have ingested plastic or other human rubbish. The study, led by Dr Qamar Schuyler from UQ's School of Biological Sciences, found the east coasts of Australia and North America, Southeast Asia, southern Africa, and Hawaii were particularly dangerous for turtles due to a combination of debris loads and high species diversity. "The results indicate that approximately 52 per cent of turtles world-wide have eaten debris," Dr Schuyler said. The study ...

Elite tennis players feel the heat at Australian Open as summers intensify

2015-09-14
Melbourne summer temperatures have been steadily climbing over the past 25 years, but even more so during the two weeks of the Australian Open in late January, new data analysis reveals. The average afternoon temperature in January has risen by 0.8 degrees Celsius per decade since 1987. But in the two weeks of the Australian Open - usually held in mid-late January - temperatures have increased by 1.25 degrees per decade. Ben Hague, a third-year Atmosphere and Ocean Sciences student at the University of Melbourne, said extreme summer temperatures have also become more ...
