Dangerous times on Brazil's Amazon frontier
(12/22/2005) Amazon land activist Deurival Santiago has the look of a hunted man. Activists like Santiago often protect peasant settlers in jungle areas where the government still has little control. That puts them in conflict with large-scale loggers, ranchers and land speculators pushing into an area of Para state known as the Terra do Meio, or Middle Land. It's the main battleground in the fight to slow destruction of the world's largest rain forest.
Chimps split from humans 5-7 million years ago says new study

Tsunami relief risks rainforest destruction
(12/19/2005) Today WWF warned that donor countries must include sustainably sourced building materials in their long-term aid packages to avoid a second ecological disaster stemming from deforestation. According to WWF, Indonesia's Aceh province will require at least 860,000 cubic meters of sawn timber for the construction of 200,000 homes over the next five years. The conservation organization says that only a small fraction of this additional demand can be met locally without resorting to illegal logging that would be damaging to Sumatra's biologically important rain forests.
Enthusiasm for tsunami-buffering mangrove projects waning
(12/19/2005) Research over the past year has shown that areas buffered by coastal forests, like mangroves, were less damaged by the 2004 tsunami than areas without tree vegetation. Accordingly, governments in tsunami-affected countries have proposed mangrove restoration projects along their coasts as a protective bioshield against storm damage.
Ancient water supply of Sahara at risk, satellite monitoring helps in water management
(12/19/2005) During the last Ice Age, the Sahara was savannah with rivers, lakes and plentiful rains. Over the past 10,000 years that landscape changed, but the rains from that period progressively percolated beneath the ground to be collected in aquifers. Today these aquifers are an important source of water for irrigating agriculture and supporting human populations in the area.

Ability to capture large prey may be origin of army ants' cooperative behvaior
(12/16/2005) Animal behvaiorist Sean O'Donnell was having an afternoon cup of coffee when a giant earthworm exploded out of the leaf litter covering the jungle floor in an Ecuadorean nature preserve. The worm, later measured at nearly 16 inches long, was pursued by a column of hundreds of raiding army ants that quickly paralyzed or killed it.
Sea slug chemical defense has potential industrial applications
(12/16/2005) When threatened by predators, sea slugs defend themselves by ejecting a potent inky secretion into the water consisting of hydrogen peroxide, ammonia and several types of acids. A team of researchers with the Atlanta-based Center for behvaioral Neuroscience (CBN) has found that this secretion is produced from normally inert chemicals stored separately in two glands. The discovery, published in the Dec. 16 on-line edition of the Journal of Experimental Biology, provides insight into a natural chemical process with potential industrial applications.

794 species on brink of extinction find study
(12/12/2005) Protecting 595 sites around the world would help address an imminent global extinction crisis, according to a study published today in the Proceedings of the National Academy of Sciences. Conducted by scientists working with the 52 member organizations of the Alliance for Zero Extinction (AZE), the study identifies 794 species threatened with imminent extinction by virtual of existing at only a single remaining site on Earth. The study found that just one-third of the sites are known to have legal protection, and most are surrounded by human population densities that are approximately three times the global average. Safeguarding these sites is key to saving these species from extinction say the authors of the study.
UN agrees to "rainforest conservation for emissions" deal
(12/11/2005) Friday, at the United Nations Framework Convention on Climate Change in Montreal, the U.N. agreed to a proposal that allows developing nations to receive financial compensation from industrialized countries for agreeing to preserve their rainforests. Environmentalists hope the deal -- set forth by ten developing countries led by Papua New Guinea -- will give developing nations a financial reason to get more involved in climate talks while safeguarding globally important ecosystems.

2006 Hurricane season likely to be active
(12/06/2005) The United States faces another very active Atlantic basin hurricane season in 2006, but with likely fewer landfalling intense hurricanes than in 2005 - the costliest, most destructive hurricane season ever - according to a report issued today by Philip Klotzbach, William Gray and the Colorado State University forecast team.
Warming could free far more carbon from high Arctic soil than earlier thought
(12/05/2005) Scientists studying the effects of carbon on climate warming are very likely underestimating, by a vast amount, how much soil carbon is available in the high Arctic to be released into the atmosphere, new University of Washington research shows. A three-year study of soils in northwest Greenland found that a key previous study greatly underestimated the organic carbon stored in the soil. That's because the earlier work generally looked only at the top 10 inches of soil, said Jennifer Horwath, a UW doctoral student in Earth and space sciences.
Soil moisture, root depth influence climate models
(12/05/2005) By soaking up moisture with their roots and later releasing it from their leaves, plants play an active role in regulating the climate. In fact, in vegetated ecosystems, plants are the primary channels that connect the soil to the atmosphere, with plant roots controlling the below-ground dynamics.
Somali pirates force UN food aid to take land route
(12/05/2005) Facing a plague of piracy off the Horn of Africa that has closed its usual supply lines by sea, the United Nations World Food programme (WFP) today announced the arrival in southern Somalia of its first overland truck convoy carrying food aid in almost five years, and called for urgent funding to make up for the increased costs.

70 years after logging, forests don't hold as much carbon as original forests
(12/05/2005) New research out of Ohio State University suggests that following logging, temperate forests take long periods of time to recover their carbon storing capacity. The scientists examined forests of of the upper Great Lakes region, which were 90% logged at the turn of the century, and found that they store only half the carbon the original forests contained. Poor forest management is blamed for the shortfall.

Amazon rainforest biodiversity due to biology not climate change says study
(12/05/2005) The biodiversity of the Amazon rainforest results from biological factors, not climate change as widely thought, says new research published in the journal Proceedings of the Royal Society B. Scientists have long argued that the species richness of tropical forests could be due to climate change-induced fragmentation, known as the "forest refuge: theory, and other external factors that caused geographic isolation. Now, researchers from University College London say that biological influences play a greater role in driving species evolution.
Congo rainforest - 600,000 sq km slated for logging
(12/05/2005) The World Bank will meet Thursday to decide whether it will fund large-scale logging in the Democratic Republic of Congo's rainforests. The country, home to the second largest rainforest in the world after Brazil, is emerging from years of civil strife which resulted in the deaths of some 3.8 million people from violence and disease.
Companies increasingly at risk for climate change litigation says UN
(12/05/2005) Companies which contribute to climate change will increasingly face legal action according to a U.N.-sponsored report accounced last week but scheduled for released in March 2006. London-based law firm Freshfields is working with Dutch bank ABN Amro to produce the U.N. report which aims to encourage investors to address environmental, social and governance issues in their investment decisions.
Temperate forests may worsen global warming, tropical forests fight higher temperatures
(12/05/2005) Growing a forest might sound like a good idea to combat global warming, since trees draw carbon dioxide from the air and release cool water from their leaves. But they also absorb sunlight, warming the air in the process. According to a new study from the Carnegie Institution's Department of Global Ecology and Lawrence Livermore National Laboratory, planting forests at certain latitudes could make the Earth warmer.
Mysterious carnivore found in Borneo rain forest

Amazon deforestation slows in Brazil for 2005
(12/05/2005) Deforestation in the Amazon rainforest fell 37% for the 2004-2004 year according to Brazilian government figures released today. Between July 2004 and August 2005, 7,298 square miles of rainforest (18,900 square kilometers) -- an area almost half the size of Switzerland -- were destroyed. Last year the figure was 10,088 square miles (26,129 sq km kilometers) and since 1978 some 206,250 square miles (534,200 sq km) of forest has been lost.
Energy efficiency helped California grow an extra $31 billion finds study
(12/04/2005) Countering Bush administration claims to the contrary, environmental officials for the state of California and the Brazilian state of Sao Paulo have found significant evidence that greenhouse gas pollution can be substantially reduced at a profit rather than a cost. The study, commissioned by the William and Flora Hewlett Foundation, found that energy efficiency has helped the California economy grow an extra 3 percent - a $31 billion gain - compared to business as usual. Further, the researchers say that each Californian typically saved about $1,000 per year between 1975 and 1995 just through efficiency standards for buildings and appliances.

Crystal sponges can absorb carbon dioxide and fight global warming
(12/01/2005) Since the Industrial Revolution, levels of carbon dioxide---a major contributor to the greenhouse effect---have been on the rise, prompting scientists to search for ways of counteracting the trend. One of the main strategies is removing carbon dioxide (CO2) from the flue exhaust of power plants, using porous materials that take up the gas as it travels up the flue.
Biosensor Could Help People with Parkinson's, Alzheimer's Disease
(12/01/2005) An engineering researcher at the University of Arkansas has developed a wireless, implantable biosensor that may one day help physicians treat patients with neurological brain disorders such as Parkinson's Disease, Alzheimer's Disease and epilepsy. Made of carbon nanotubes, the sensor monitors and controls chemicals in the brain and communicates with other sensors to control tremors or direct the movement of prosthetic limbs.
Change in Atlantic circulation could plunge Europe into cold winters
(12/01/2005) The Atlantic Ocean circulation that carries warm waters north and returns cold waters south is slowing, putting Europe at risk of colder temperatures, according to research published in Nature. The Atlantic Heat Conveyor, the system of currents in the Atlantic Ocean that result in a net transport of warm water into the northern hemisphere, keeps western Europe warmer than regions at similar latitudes in other parts of the world. A weakening of the system, which includes the Gulf Stream, could cause a cooling in northwest Europe.

U.S. fishing bycatch wastes 1 million metric tons of fish per year
(12/01/2005) A new study shows that for every five pounds of fish caught by U.S. commercial fisheries, one pound is dumped -- dead, dying and wasted. Each year, U.S. commercial fishing operations throw away more than one million metric tons of fish, an amount equivalent to 28 percent of all commercial landings and more than all of the fish landed on the East and West coasts combined.
Overfishing of fresh waters of serious concern
(12/01/2005) Systematic overfishing of fresh waters occurs worldwide but is largely unrecognized because of weak reporting and because other pressures can obscure fishery declines, according to an article in the December 2005 issue of BioScience.
U.S. "exporting" carbon emissions to China says study
(12/01/2005) The growth of Chinese imports in the U.S. economy boosted the total emissions of carbon dioxide (a primary greenhouse gas) from the two countries by over 700 million metric tons between 1997 and 2003, according to a study published online in the journal Energy Policy. The analysis, prepared by two scientists at the National Center for Atmospheric Research, suggests that American emissions of carbon dioxide in 2003 would have been 6% higher if the United States had manufactured the products that it imported from China. Meanwhile, China's 2003 emissions would have been 14% lower had it not produced goods for the United States.
Australian industry embraces green energy while government fights emissions cuts

Toucan Beaks Are Models Of Lightweight Strength says UCSD engineer
(11/30/2005) As a boy growing up in Brazil 40 years ago, Marc A. Meyers marveled at the lightweight toughness of toucan beaks that he occasionally found on the forest floor. Now a materials scientist and professor of mechanical and aerospace engineering at UCSD's Jacobs School of Engineering, Meyers said makers of airplanes and automobiles may benefit from the first ever detailed engineering analysis of toucan beaks conducted in his lab.
Study uncovers how thousands of tree species coexist in rain forest
(11/30/2005) A group of scientists have a developed a new theory to explain why the biodiversity of tropical rain forests is so high and how species are assembled in an ecological community. According to their research presented in Nature, the answer can be found in 'neutral theory' whereby community membership is determined by just five fundamental processes. The scientists say that species will regulate themselves to make room for each other if they follow the 'membership rules.' The new theory undermines the conventional 'niche theory' which has been traditionally used to explain community assemblages.
Rise in deer ticks put East Coast hikers at risk says Penn State entomologist
(11/30/2005) Every year it seems the tick identification laboratory in Penn State's entomology department receives more submissions from residents around the state than the year before. But Steven Jacobs, the extension entomologist who oversees the lab, said this year is different.

(11/30/2005) Researchers outline in the November issue of Mayo Clinic Proceedings their study of postmenopausal women, which supports the hypothesis that women who smoke cigarettes before first full-term pregnancy have a 20 percent increased risk of breast cancer compared with women who began smoking after the birth of their first child or were never smokers.
75% of Switzerland's glaciers gone by 2050, Europe heats up
(11/30/2005) The four hottest years on record were 1998, 2002, 2003 and 2004. Ten percent of Alpine glaciers disappeared during the summer of 2003 alone. At current rates, three quarters of Switzerland's glaciers will have melted by 2050. Europe has not seen climate changes on this scale for 5 000 years, says a new report by the European Environment Agency.
Bird songs can serve as a warning system to detect ecological disturbances
(11/30/2005) Changes in bird song could be used as an early warning system to detect man-made ecological disturbances, new research published in the British Ecological Society's Journal of Applied Ecology has found.
Rainforests worth $1.1 trillion for carbon alone in Coalition nations
(11/29/2005) If a coalition of developing countries has its way, there could soon be new forests sprouting up in tropical regions. The group of ten countries, led by Papua New Guinea, has proposed that wealthy countries pay them to preserve their rainforests. The Coalition for Rainforest Nations argues that all countries should pay for the benefits -- from carbon sequestration to watershed protection -- that tropical rainforests provide.
2005 Atlantic hurricane season worst on record

Vaccination can prevent bird flu epidemic
(11/28/2005) Vaccinating chickens against avian flu can prevent a major outbreak of the disease by preventing birds from passing on the virus, according to research published by Dutch scientists on Monday.
Atmospheric carbon dioxide levels closely correlated with global temperatures
(11/28/2005) Studying ice cores from Antarctica, scientists of the Alfred Wegener Institute for Polar and Marine Research extended the record of historic concentrations of carbon dioxide, methane and nitrous oxide in the atmosphere by 250,000 years. The team found a close correlation between atmospheric carbon dioxide levels and global temperatures. Over the past 650,000 years, low greenhouse gas concentrations have been associated with cooler conditions. The current concentration of atmospheric carbon dioxide, at 380 parts-per-million, is the highest level recorded over the past 650,000 years.
Developing countries: pay us to save rainforests
(11/27/2005) At this week's United Nations summit on climate change in Montreal a coalition of tropical developing countries plans to propose that wealthy countries pay them to preserve their rainforests. The group of 10 countries, led by Papua New Guinea and Costa Rica, will argue that they should be compensated for the services rainforests provide the rest of the world.
Average temperatures climbing faster than thought in North America
(11/27/2005) Tree rings and borehole drill samples have added to the evidence that average temperatures in North America have risen steadily in the past 150 years according to a new study by researchers at Oregon State University and the University of Utah. In their paper published in Journal of Geophysical Research, scientists found that average temperatures in the Northern Hemisphere increased about 1.5 degrees since the beginning of the industrial revolution when atmospheric carbon dioxide concentrations began to increase sharply.
Exploring freshwater fish habitats in the rainforest of Peru
(11/26/2005) This fall the editor of mongabay.com, a leading environmental science and tropical freshwater fish information site, traveled to the Peruvian Amazon and examined habitats for freshwater fish. As a result of this effort, two new biotope descriptions have been posted on the site. The descriptions include underwater photographs for those interested in replicating the natural conditions of these habitats.
"Health" beer could help prevent cancer

Oil sands' development for energy a threat to environment says group
(11/25/2005) Wednesday the Pembina Institute released "Oil Sands Fever: The Environmental Implications of Canada's Oil Sands Rush" [PDF]. According to the report's main author, Dan Woynillowicz, "The story of Canada's rapid development of the oil sands has only been partially told. What's been missing from all the discussion and reporting is a comprehensive look at the environmental consequences of this development".
