Amazon rainforest fires date back thousands of years
(03/14/2007) Fires are nothing new to the Amazon reports a study published in the journalBiotropica. Analyzing soils in the eastern Amazon, a team of scientists led by David S. Hammond of NWFS Consulting, has found evidence of forest fires dating back thousands of years. While the origin of these fires is unclear, the authors propose intriguing scenarios involving pre-Colombian human populations and ancient el Nino events which could have so dried rainforest areas that they became more prone to forest fires.
New cat species discovered in Borneo
(03/14/2007) Scientists have declared that the clouded leopard found on the islands of Borneo and Sumatra is an entirely new species of cat, genetically distinct from the clouded leopard that lives in mainland southeast Asia. The scientists say that the two species of clouded leopard appear to have diverged about 1.4 million years ago. They also note that the results of the genetic study are supported by separate research on geographical variation in the coat color of the clouded leopard.
Ivory-billed Woodpecker sighting may be a mistake
(03/14/2007) A new study casts doubt on the apparent rediscovery of the Ivory-billed Woodpecker in Arkansas. J. Martin Collinson, a researcher at the University of Aberdeen in Scotland, says that the sighting of the thought-to-be-extinct bird is a case of mistaken identity. Using video analysis, Collinson argues that ornithologists have confused the Ivory-billed Woodpecker (Campephilus principalis) with the similar Pileated Woodpecker (Dryocopus pileatus).
Clean coal is a vital energy source for the future says MIT report
(03/14/2007) Coal is a cheap and widely available energy source that will be continue to be used in the future despite its impact on global climate. For this reason, says a new report by MIT, it is essential to develop cleaner technologies for harnessing coal.

(03/12/2007) Brazil's second largest exporter of beef has won approval of a controversial loan from the International Finance Corporation (IFC), the private equity lender of the World Bank, according to a report from the Associated Press. Environmentalists say the deal will drive further deforestation in the biologically rich Amazon rainforest. Cattle ranching is responsible for more than half of forest loss in the region.
Plug-in cars could help fuel Austin power grid
(03/12/2007) The city of Austin, Texas hopes to launch an ambitious plan using plug-in electric cars to reduce pollution and improve power grid management, reports an article in today's Wall Street Journal. Under the initiative put forth by Roger Duncan, deputy manager of Austin Energy, the city-owned electric utility, and backed by mayor Will Wynn, the plug-in electric cars would serve as sort of giant battery from which the city grid could draw power during peak demand.
Wind energy speculation jumps in Texas, but Exxon on sidelines
(03/12/2007) While speculative energy ventures are nothing new in Texas, today companies are taking risky gambles in wind power argues an article that appears in today's issue of The Wall Street Journal (WSJ). The WSJ reports that energy firms are investing hundreds of millions of dollars in some of the most remote -- and windy -- parts of Texas, but notes that the investments will only pay off with government subsidies.
Ancient humanoids were short and nasty for kung fu fighting, not climbing
(03/12/2007) Ancient ape-like human ancestors called as australopiths were short-legged to help them fight, not to climb trees, argues a new study from a researcher at the University of Utah.
Biodiversity extinction crisis looms says renowned biologist
(03/12/2007) While there is considerable debate over the scale at which biodiversity extinction is occurring, there is little doubt we are presently in an age where species loss is well above the established biological norm. Extinction has certainly occurred in the past, and in fact, it is the fate of all species, but today the rate appears to be at least 100 times the background rate of one species per million per year and may be headed towards a magnitude thousands of times greater. Few people know more about extinction than Dr. Peter Raven, director of the Missouri Botanical Garden. He is the author of hundreds of scientific papers and books, and has an encyclopedic list of achievements and accolades from a lifetime of biological research. These make him one of the world's preeminent biodiversity experts. He is also extremely worried about the present biodiversity crisis, one that has been termed the sixth great extinction.
New Snapper Species Discovered in Brazil
(03/09/2007) A new species of snapper was discovered off the coast of Brazil.

Air pollution can reduce rainfall
(03/08/2007) Air pollution can reduce rainfall in mountainous areas according to research published in Friday's issue of the journal Science. 50 years of measurements at Mt. Hua near Xi'an, in central China, show that precipitation levels can be decreased by 30 to 50 percent during hazy conditions. The researchers say this is the result of high concentrations of particulates in the air which cause cloud droplets to be smaller and less likely to become raindrops.

Ecuadorian brothers show conservation-based microentrepreneurship possible
(03/07/2007) Tropical rainforests are declining across most of the world. Since the close of the 1990s deforestation rates have only accelerated as growing levels of consumption and consistent population growth paint an increasingly bleak future for the world's forests and their resident biodiversity. These trends make it easy to lose hope. As such, stories that show local people earning a livelihood from biodiversity conservation are an inspiration.
Deforestation causes species extinction in Madagascar
(03/07/2007) Deforestation has already caused the extinction of a large number of endemic insect species on the island of Madagascar, according to new research published in the March edition of the journal Biology Letters. The work suggests that only half the species confined to these forest areas will survive.
World's only blue lizard heads toward extinction
(03/07/2007) High above the forest floor on the remote Colombian island of Gorgona lives a lizard with brilliant blue skin, rivaling the color of the sky. Anolis gorgonae, or the blue anole, is a species so elusive and rare, that scientists have been unable to give even an estimate of its population. Due to the lizard&spod;s isolated habitat and reclusive habits, researchers know little about the blue anole, but are captivated by its stunning coloration.
Gold mining in Guyana damages environment, threatens Amerindians
(03/06/2007) Informal gold mining is causing environmental harm and human rights abuses in Guyana says a new report from the International Human Rights Clinic (IHRC) of Harvard Law School's Human Rights Program. Wildcat gold mining has been a serious problem in the Guiana shield countries of Brazil, Venezuela, Guyana, Suriname and French Guiana. Rising gold prices in recent years have only worsened the problem, as illegal miners have flooded the region clearing forest, polluting rivers, and making threats against indigenous people.
Pre-Colombian Amazon rainforest not heavily populated
(03/06/2007) Much of the Amazon rainforest was not heavily populated by pre-Colombian indigenous cultures argues a new paper published in the journal Philosophical Transactions of the Royal Society B: Biological Sciences. The work challenges an increasingly accepted theory -- popularized in Charles C. Mann's 1491: 'New Revelations of the Americas Before Columbus' -- the Amazon supported dense, sedentary populations prior to the arrival of Europeans.

U.S. GHG emissions to rise 20% by 2020
(03/03/2007) The United States expects to emit 19 percent more greenhouse gases in 2020 than it did in 2020 according to a report from the Associated Press. The draft report, which is still in progress and is more than a year late, projects 9.2 billion tons of greenhouse gas emissions in 2020, a 19 percent increase from 7.7 billion tons in 2000, if the Bush Administration climate policy proceeds as planned.
Fish extinctions alter critical nutrients in water, study shows
(03/03/2007) Ecosystems are such intricate webs of connections that few studies have been able to explore exactly what happens when a species dies out. Now, a Cornell study using computer simulations has teased out how the disappearance of a freshwater fish can affect the availability of certain nutrients that other species rely on.
Tradable biodiversity rights can help to conserve species richness
(03/02/2007) The decline in biodiversity compels us to look at the sustainable use of living resources in a different manner. To conserve biodiversity, the social and economic aspects of the use of biodiversity must be taken into account, in addition to the ecological aspects. From this perspective it then becomes clear, for example, that the portion of the world population that lives in poverty is incapable of contributing to the conservation of biodiversity. In their daily search for food, energy and shelter, they simply cannot pay attention to this aspect. Professor Steven De Bie made this point during his acceptance of the endowed chair in the Sustainable Use of Living Resources on 1 March at Wageningen University. To compensate for this decline in biodiversity in the poorer regions, De Bie proposes establishing tradable 'biodiversity rights'.
