(04/10/2007) Biologists have documented the first known case of moths feeding on the tears of birds. The research, published in the January 4 2007 issue of the journal Biology Letters, reports that Hemiceratoides hieroglyphica 'attacks sleeping birds in Madagascar' using its sharply barbed proboscis to penetrate the bird's eye. While similar behvaior has been reported in mammals, this is the first known case of tear-feeding on birds.
Climate change will worsen drought, hunger in Africa
(04/10/2007) Africa will suffer the brunt of climate change reports the latest installment of the Intergovernmental Panel on Climate Change (IPCC). The IPCC says that the projected increases in greenhouse gas emissions will put up to 1.8 billion more Africans at risk of water stress this century. Modest rises in temperature will reduce water availability in parts of the continent.
Concentrating solar power better option than nuclear
(04/10/2007) Regarding Nuclear power plants are financially risky given high costs, there is absolutely no need for nuclear power in the US because there is a simple mature technology that can deliver huge amounts of clean energy without any of the headaches of nuclear power.
TXU hopes to build nuclear reactors instead of coal-fired power plants
(04/10/2007) Texas energy company TXU will abandon plans to build coal-fired power planets and will instead focus on building the largest nuclear power plants in the United States according to an article from The Wall Street Journal. Despite reduced emissions of greenhouse gases, the decision will likely prove controversial due to the high cost of nuclear energy. Without substantial subsidies nuclear energy is rarely cost-competitive with coal or renewable power sources.
Could global deforestation fight climate change?
(04/09/2007) While many climate change mitigation schemes rely on reforestation schemes to sequester carbon dioxide from the atmosphere, those located in temperate regions may actually be warming the planet, worsening global change, reports a new study published in the April 9-13 online edition of the Proceedings of the National Academy of Sciences. Surprisingly, the research suggests that global-scale deforestation would produce a net cooling effect, but that forest preservation efforts and reforestation in the tropics is more effective in cooling the planet.
Man swims entire length of Amazon river
(04/09/2007) Slovenian marathon swimmer Martin Strel became the first person to swim the entire length of the Amazon River Saturday when he arrived in Belem, Brazil. Strel was immediately taken to the hospital in critical condition but is now recovering in a local hotel.
Congo cancels logging contracts
(04/09/2007) The new government of the Democratic Republic of Congo (DRC) cancelled more than 20 illegally-granted logging contracts which covered nearly three million hectares (7.4 million acres) of forest, according to a report from AFP. The announcement came at the International conference on the sustainable management of the forests in the DRC (ConForDRC) held February 26-27 in Brussels. At the conference policymakers agreed that Congo should maintain its moratorium on new logging and provide legal recognition for the rights of indigenous forest dwellers. There was wide support for Congo's participation in the Coalition of Rainforest Nations' proposal to seek compensation for forest conservation.
Indonesia seeks to increase deforestation rate, already world's highest
(04/09/2007) Already having the highest deforestation rate in the world, Indonesia's Minister of Forestry announced the country would increase its harvest quota for natural timber for 2007 by 12 percent to 9.1 million cubic meters according to the International Tropical Timber Organization (ITTO). ITTO said the target quota may actually be 12.4 million cubic meters (53 percent higher than 2006) for the year.
Maize cultivated at least 7,300 years ago in Mexico
(04/09/2007) Anthropologists have found the earliest known evidence of maize cultivation in Mexico. The discovery, published in the April 9-13 edition of the journal Proceedings of the National Academy of Science, pushes back farming of the ancestor of modern corn to about 7,300 years ago.

Nuclear power plants are financially risky given high costs
(04/04/2007) Nuclear power plants are risky investments given rapidly rising costs of construction of nuclear fuel, reports a new study by researchers from Georgetown University, Stanford University and UC Berkeley.
Palm oil doesn't have to be bad for the environment
(04/04/2007) As traditionally practiced in southeast Asia, oil palm cultivation is responsible for widespread deforestation that reduces biodiversity, degrades important ecological services, worsens climate change, and traps workers in inequitable conditions sometimes analogous to slavery. This doesn't have to be the case. Following examples set forth by the Roundtable on Sustainable Palm Oil and firms like Golden Hope Plantations Berhad, a Malaysian palm oil producer, oil palm can be cultivated in a manner that helps mitigate climate change, preserves biodiversity, and brings economic opportunities to desperately poor rural populations.
Cane toads to invade 2 million square kilometers of Australia
(04/03/2007) Cane toads are dramatically expanding their range in Australia and may eventually double their current extent to occupy over 2 million square kilometers, according to new projections by a team of scientists writing in Proceedings of The Royal Society B: Biological Sciences. The researchers report that the invasive amphibians increasingly occupying zones outside their native conditions, putting native Australian species at ever greater risk.
Eco-friendly palm oil could help alleviate poverty in Indonesia
(04/03/2007) The Associated Press (AP) recently quoted Marcel Silvius, a climate expert at Wetlands International in the Netherlands, as saying palm oil is a failure as a biofuel. This would be a misleading statement and one that doesn't help efforts to devise a workable solution to the multiplicity of issues surrounding the use of palm oil.
Sixth cyclone hits Madagascar; impact 'like tsunami'

Wildlife conservation plan moves forward in southern Sudan
(04/03/2007) A leading conservation group announced that it has signed two agreements with the Government of Southern Sudan (GoSS) to launch a conservation strategy for the region's wildlife. The New York-based Wildlife conservation Society says that southern Sudan may have some of the richest wildlife in Africa.
2007 hurricane season will be 'very active' but not due to global warming
(04/03/2007) Developing La Nina conditions, not global warming, should make the 2007 Atlantic hurricane season 'very active' according to a top U.S. hurricane forecaster. William Gray of the Department of Atmospheric Science at Colorado State University said he expects 17 named storms this year, including 9 hurricanes. He says there is a 74 percent chance that a category 3, 4, or 5 hurricane will hit the U.S. coastline (the historic average for the past century is 52 percent) and a 49 percent chance that such a storm would hit the Gulf Coast of the United States (versus an average of 30 percent for the past century).
Congo forest elephants declining from logging roads, illegal ivory
(04/02/2007) Fast-expanding logging roads in the Congo basin are becoming 'highways of death' for the fierce but elusive forest elephant, according to a new study published in the journal Public Library of Science. Logging roads both provide access to remote forest areas for ivory poachers and serve as conduits of advancing human settlement.
Photos of baby colobus monkey born at Central Park Zoo
(04/02/2007) A baby colobus monkey born at the Central Park Zoo in New York is doing well according to the Wildlife conservation Society. The infant, presently all white in color, will develop its characteristic black and white coat within the next three months. Colobus monkeys are native to the forests of Central Africa, ranging from Nigeria to Ethiopia and down into Kenya, Uganda and Tanzania.
Global warming could hurt salmon fisheries in Pacific Northwest
(04/02/2007) Global warming could cause Chinook salmon populations in Washington state to decline 20-40 percent by 2050 according to a new study published in the online early edition of PNAS. The researchers urge policymakers to focus on restoration of lower elevation habitats in order to reduce the expected impact of climate change on salmon populations.
Supreme Court rebukes Bush Administration on global warming rule
(04/02/2007) The U.S. Supreme Court ruled against the Bush Administration in a landmark case with global warming implications. In Massachusetts v. EPA, the Supreme Court ruled 5-4 that (1) state governments and environmental groups have the right to sue the EPA, and (2) the EPA has the right to regulate CO2 emissions as a pollutant under the Clean Air Act. On a third point, where the EPA can choose not to regulate CO2 emissions, the Supreme Court directed the agency to "reconsider its refusal based on the factors set forth in the law."
Deadly cyclones hurt conservation efforts in Madagascar
(04/02/2007) As Madagascar braces for the arrival of the sixth major cyclone (Gaya) to hit the Indian Ocean island this season, researchers from a prominent conservation have asked for help in the relief and recovery effort. Local officials with the Bronx Zoo-based Wildlife conservation Society say that the series of storms have left tens of thousands of people homeless, devastated croplands, and diverted already short funds from conservation activities.
Antarctic insects make natual anti-freeze to survive cold
(04/02/2007) Insects in the some of the world's coldest places produce natural anti-freeze that enables them to survive sub-freezing temperatures for months on end according to research represented at the Society for Experimental Biology's Annual Meeting in Glasgow.
The news of extinction: western media's response to the demise of the Baiji
(04/01/2007) The news came and went with an alacrity that I found alarming, almost jolting. I waited for weeks, faithfully; I could not believe that the initial announcement would be followed by nothing but silence on the issue, no rationalizations, no opinions, no discussions, no outpourings of grief. Just silence.
Detecting poisons in nectar is an odour-ous task for honeybees
(04/01/2007) Though many spring flowers have bright advertisements offering sweet rewards to honeybees, some common flowers have not-so-sweet or even toxic nectars. Why plants would try to poison the honeybees they wish to attract is a scientific mystery.
Insects cultivate antibiotic-producing bacteria in their antennae
(04/01/2007) Bacteria live in, on and around us and other organisms with sometimes very beneficial results. For the first time scientists have shown that one species of insect deliberately cultivates bacteria in its antennae in order to protect their larvae from fungal attack. This highly specialised interaction between an insect species and bacteria protects the insect's offspring against microorganisms which might infect it during its cocoon stage.
Pythons turn bones of prey into calcium
(04/01/2007) Burmese pythons don't eat very often, but when they do they like to pig out, ingesting the whole of their prey. There's very little waste as they are able to digest everything, apart from hair and feathers. Dr Jean-Herv Lignot (Louis Pasteur University) and Dr Robert K. Pope (Indiana University South Bend) will talk about the implications this has on the way these snakes digest food on Saturday 31st March at the Society for Experimental Biology's Annual Meeting in Glasgow.
Fruit bats crave sugar to overcome 'hangover'
(04/01/2007) Many of us will be familiar with cravings for sweet food, after having overindulged in alcohol the night before. It appears that Egyptian fruit bats also crave particular types of sugar to reduce the effects of ethanol toxicity.
Brazil to give Amazonian tribes Internet access to fight deforestation
(03/30/2007) Brazil will offer free satellite Internet connections to indigenous tribes in the Amazon according to a report from Reuters. It says that the plan will help reduce illegal logging by enabling natives to monitor and report on illicit activities.
Madagascar needs relief help after deadly cyclones
(03/30/2007) A deadly cyclone has struck one of the most biologically diverse parts of the planet, forcing people from their homes and damaging their only source of livelihood. Cyclone Indlala has displaced more than 100,000 people and caused widespread crop losses in northeastern Madagascar according to reports from relief organizations. 100-mph (165 km/h) winds and heavy rains caused considerable damage in coastal areas in the northeastern part of the Indian Ocean island. 95 people were reported dead but there are fears of spreading water-borne disease.
Australia puts $200M toward rainforest conservation
(03/30/2007) Australia has committed A$200m ($160m) to global forest conservation efforts to help fight illegal logging and slow global warming.

U.S. can cut oil imports to zero by 2040, use to zero by 2050
(03/29/2007) The United States could dramatically cut oil usage over the next 20-30 years at low to no net cost, said Amory B. Lovins, cofounder and CEO of the Colorado-based Rocky Mountain Institute, speaking at Stanford University Wednesday night for a week-long evening series of lectures sponsored by Mineral Acquisition Partners, Inc.
Overfishing of sharks causing shellfish decline
(03/29/2007) Overfishing of large sharks is reducing the abundance of shellfish reports a study published in the March 30 issue of the journal Science. A team of Canadian and American biologists has found that population declines in large predatory shark species -- including bull, great white, dusky, and hammerhead sharks -- due to overfishing has led to a boom in their ray, skate, and small shark prey species along the Atlantic Coast of the United States. Now these smaller species are depleting commercially important shellfish.
Some corals may survive acidification caused by rising CO2 levels
(03/29/2007) Several studies have shown that increased atmospheric carbon dioxide levels are acidifying the world's oceans. This is significant for coral reefs because acidification strips carbonate ions from seawater, making it more difficult for corals to build the calcium carbonate skeletons that serve as their structural basis. Research has shown that many species of coral, as well as other marine microorganisms, fare quite poorly under the increasingly acidic conditions forecast by some models. However, the news may not be bad for all types of corals. A study published in the March 30 issue of the journal Science, suggests that some corals may weather acidification better than others.
Non-CO2 gases also cause global warming
(03/29/2007) While most of the focus in developing a policy to fight global warming has been on carbon dioxide, other gases also contribute to climate change. The effect of these gases is still poorly understood and should be the subject of further research say two climate scientists writing in the March 30 issue of the journal Science.
Important Congo basin parks get funding
(03/28/2007) A network of national parks and protected areas spanning three nations in Central Africa's Congo Basin, has received long-term funding through the establishment of a trust fund, thus ensuring further protection of the region's wildlife, according to the Wildlife conservation Society.
Lightning may be used to predict volcanic activity
(03/28/2007) While it has long been known that volcanic eruptions can produce vigorous lightning, there are few direct observations of the phenomena, states the article. Following the initial eruptions of Jan. 11 and 13, 2006, two of which produced lightning, two electromagnetic lightning detectors were set up in Homer about 60 miles from Augustine. A couple of days later, the volcano erupted again, with the first of four eruptions producing a "spectacular lightning sequence."
Dinosaur extinction didn't produce current mammal evolution
(03/28/2007) A new Nature study argues that the demise of dinosaurs did not fuel the rise of mammals. Devising a new tree of life for 4,500 species of mammals using molecular evolutionary trees, an international team of researchers challenges the prevailing hypothesis that a mass extinction of dinosaurs 65 million years ago played a major role in the diversification of mammals.
CO2 levels tightly linked with climate change over past 420 million years
(03/28/2007) New research shows that sensitivity of Earth's climate to changes in the greenhouse gas carbon dioxide (CO2) have been relatively consistence for at least 420 million years, suggesting that presently rising levels of carbon dioxide resulting from fossil fuel use will indeed produce higher temperatures in the future.
U.S. government seeks to weaken Endangered Species Act
(03/28/2007) The Bush Administration is seeking to rewrite the Endangered Species Act to significantly reduce its effectiveness in protecting threatened species say environmentalists who released secret U.S. government documents on the issue.
