Forest protection best way to control rats finds study
(04/13/2006) The most cost-effective way to stop non-native rats and mongoose from decimating highly endangered species on larger tropical islands is not by intensive trapping, but instead by preserving the forest blocks where wildlife live, according to a study by the Bronx Zoo-based Wildlife conservation Society (WCS) and other groups.
Fish Flow with the Floods in the Amazon
(04/12/2006) The entire life of the Tambaqui, also called a Pacu, follows the annual rise and fall of the floodwaters. The young are born in the river channel and are carried by the high water into the floodplain, where they live in the floating meadows and eat grass seeds. The fish use their keen senses of smell and vision to find their favorite fruits and seeds in the forest. Tambaqui are unique in their love for rubber tree seeds. They crush the hard seed coating with large molar-like teeth and swallow the seed whole. This does not destroy the seed, in fact, the process is a necessary step in germination, or preparing the seed to sprout. Later, the seed will grow into a rubber tree.
Plants may absorb less carbon dioxide than initially believed
(04/12/2006) The world's land plants will probably not be able to absorb as great a share of the rising atmospheric carbon dioxide as some models have predicted, according to a new study led by Peter B. Reich, professor in the department of forest resources at the University of Minnesota. The work showed that limitations on the availability of nitrogen, a necessary nutrient, will likely translate to limitations on the ability of plants to absorb extra carbon dioxide.
Carbon trading could save rainforests
(04/12/2006) A new rainforest conservation initiative by developing nations offers great promise to help slow tropical deforestation rates says William Laurance, a leading rainforest biologist from the Smithsonian Tropical Research Institute in Panama, in an article appearing Friday in New Scientist.
Rainforest education site goes online; resources for students, teachers, and journalists
(04/12/2006) Mongabay.com, a leading environmental-science web site, announced today a revised version of a rainforest site, that has been a major resource on such forests for teachers, children, and researchers. "Mongabay.com is dedicated to providing necessary communication to those interested in the fate of our rainforests," Ira Rubinoff, director of the Smithsonian Tropical Research Institute (STRI), said. "It has a scientific base that should provide reliable information to all who share an interest in the future quality of life on this planet." The revised site includes environmental profiles and deforestation statistics for more than 60 countries, and features thousands of rainforest wildlife photos from around the world. Additionally, the site includes a section geared towards children, with learning activities and educational resources for teachers.

In an unusually public exchange, Jason Vines, vice president of communications for DaimlerChrysler's U.S. arm criticized Exxon Mobil Corp, the world's most profitable company, in a blunt blog posting.
Rivers are the highways of the Amazon
(04/11/2006) Rivers are the highways of the Amazon. Instead of driving cars and trucks, people use use boats to travel from place to place. Launchas are large boats powered by strong engines that travel up and down all the major rivers in the Amazon Basin. We have spent the last two day nights and two night on a launcha that is traveling up the Amazon River at about 10 miles an hour.
Brazil closes down illegal timber operation, seizes wood
(04/11/2006) Brazilian environmental authorities closed down an illegal logging operation in the Amazon according to a report from the Associated Press. An agent with Ipaam, the environmental authority of Amazonas state, told Michael Astor of the Associated Press that the Norte Wood logging company was operating without a license in town of Novo Aripuana. The agency made one arrest and seized 500 cubic meters of wood in the raid.

Exploring the Flooded Streets of Iquitos, Peru
(04/09/2006) Belen is on the edge of the large city of Iquitos. Belen is unique because much of the city is covered in water for most of the year. From January to May the streets, soccer fields, and gardens are underwater. Many of the houses are built on rafts that float up and down as the river rises and falls. Other houses are built on stilts so that the water does not cover the house when the water rises. The floating city was full of life: people paddling canoes, children swimming and laughing, people going about their daily lives in houses floating on the Amazon River.
Ants are 140-168 million years old
(04/07/2006) Ants are considerably older than previously believed, having originated 140 to 168 million years ago, according to new research on the cover of this week'apos;s issue of the journal Science. But these resilient insects, now found in terrestrial ecosystems the world over, apparently began to diversify only about 100 million years ago in concert with the flowering plants, the scientists say
Greenpeace accuses McDonald's of destroying the Amazon rainforest
(04/07/2006) After a year-long investigation, environmental group Greenpeace has accused McDonald's and other western firms of contributing to deforestation in the Amazon. Greenpeace's report, published today, alleges that much of the soy-based animal feed used by fast-food chains to fatten chickens is derived from soybeans grown in the Amazon Basin of Brazil. Thanks to a new variety of soybean developed by Brazilian scientists to flourish in rainforest climate, soybean production has boomed in the region in recent years as firms have converted extensive areas of rainforest and cerrado, a savanna-like ecosystem, into industrial soybean farms. High soybean prices have also served as an impetus to expanding soybean cultivation and Brazil is on the verge of supplanting the United States as the world's leading exporter of soybeans.
Tropical deforestation rates to slow in future - new study
(04/06/2006) As human population growth rates diminish in coming years deforestation rates are expected to slow according to research published in Biotropica online. The report offers hope that reduced rates of forest conversion can stave off a future extinction crisis in the tropics, where most of the world's biodiversity is found. Scientists estimate that as much as 50 percent of the planet's terrestrial biodiversity is found in tropical rainforests distributed around the world but the United Nations recently warned that the current rate of extinction is running 100 to 1,000 times the normal background rate.
Newly discovered rodent not so new or rare after all
(04/05/2006) The newly discovered species of rodent found in a marketplace in Central Laos turns out to not be so new or so rare after all. The Laotian rock rat (Laonastes aenigmamus), as the long-whiskered and stubby-legged rodent is now known, is a species believed to have been extinct for 11 million years. It is a member of a family that, until now, was only known from the fossil record. The species was first described by Wildlife conservation Society (WCS) researcher Dr. Robert Timmins after it was found on a table at a hunter's market in central Laos. In a return trip to the market, WCS conservationist Peter Clyne found the rats to be quite common, photographing several specimens. According to Clyne, the rat is commonly brought in by hunters and eaten by local people.
The Adventure Begins: Wilderness Classroom in Peru
(04/05/2006) We boarded a plane in Chicago at 6 pm on Saturday energized and excited about our trip to Peru. When our plane landed in Lima early on Sunday morning, we were very tired and ready for bed. I think traveling 500 miles per hour at 35,000 feet that makes it hard for me to sleep on airplanes. I think Anna and Patrick were having the same problem.
Giant "Turkeysaurus" dinosaur found in Utah
(04/05/2006) Scientists from the University of Utah and the Utah Museum of Natural History have discovered the remains of a new bird-like, meat-eating dinosaur in Grand Staircase-Escalante National Monument (GSENM), southern Utah. Although represented only by the fossilized remains of hand and foot bones, comparisons with more complete skeletons found in Asia demonstrate that this animal was about seven feet tall when standing upright. Discovery of this Utah giant, which is much larger than its counterparts in Canada and the northern US, nearly doubles the documented range of these dinosaurs in North America, and demonstrates that they roamed much farther south than previously thought.
Colombia's indigenous communities under threat warns UN agency
(04/05/2006) A humanitarian emergency is looming among Colombia's indigenous communities, with some threatened with extinction in the South American country's decades-long civil conflict, as irregular armed groups encroach upon their land, even torturing and killing their leaders, the United Nations refugee agency warned today.
Report makes case for regulating carbon dioxide emissions
(04/05/2006) A new report evaluating air pollution trends at the nation's 100 largest electric power producers shows that emissions of sulfur dioxide (SO2) and nitrogen oxides (NOx) have fallen markedly in recent years, but carbon dioxide (CO2) emissions increased and will likely spike in coming years. The report comes amid increasing public concern and intensifying pressure for limits on heat-trapping emissions from U.S. power plants and rising investor concern about companies' long-term financial risk from climate change. In the absence of federal regulations, business uncertainty is growing as more U.S. states and regions move to enact their own limits on CO2 emissions from power plants. The U.S. government has opted for voluntary controls on carbon dioxide, but last year the U.S. Senate adopted a resolution calling for mandatory emission limits.
Recent Coral Bleaching at Great Barrier Reef
(04/05/2006) An international team of scientists are working at a rapid pace to study environmental conditions behind the fast-acting and widespread coral bleaching currently plaguing Australia's Great Barrier Reef. NASA's satellite data supply scientists with near-real-time sea surface temperature and ocean color data to give them faster than ever insight into the impact coral bleaching can have on global ecology. Australia's Great Barrier Reef is a massive marine habitat system made up of 2,900 reefs spanning over 600 continental islands. Though coral reefs exist around the globe, researchers actually consider this network of reefs to be the center of the world's marine biodiversity, playing a critical role in human welfare, climate, and economics. Coral reefs are a multi-million dollar recreational destinations, and the Great Barrier Reef is an important part of Australia's economy.
United States and Indonesia to fight illegal logging
(04/05/2006) The United States and Indonesia today agreed to fight illegal logging in some of the world's most diverse rainforests. Indonesian Trade Minister Mari Elka Pangestu and Chief of the US Trade Office (USTR) Robert Portman said the two countries will coordinate efforts of protect Indonesia's forests which have been significantly degraded and destroyed by the illicit timber trade. While Indonesia houses the most extensive rainforest cover in all of Asia, its natural forest area is rapidly being reduced by logging--most of which is illegal. Between 1990 and 2005 the country lost more than 28 million hectares of forest, including 21.7 million hectares of virgin forest, according to data from the United Nations.
Picture of ancient missing link between fish and land animals
(04/05/2006) Paleontologists have discovered fossils of a species that provides the missing evolutionary link between fish and the first animals that walked out of water onto land about 375 million years ago. The newly found species, Tiktaalik roseae, has a skull, a neck, ribs and parts of the limbs that are similar to four-legged animals known as tetrapods, as well as fish-like features such as a primitive jaw, fins and scales. These fossils, found on Ellesmere Island in Arctic Canada, are the most compelling examples yet of an animal that was at the cusp of the fish-tetrapod transition. The new find is described in two related research articles highlighted on the cover of the April 6, 2006, issue of Nature.
California plans to cut greenhouse gas emissions
(04/04/2006) California plans to introduce legislation that will impose binding limiting on future greenhouse gas emissions. The state aims to cut current levels of emissions 10 percent by 2020, to bring pollution in line with 1990 levels. It would become the first state to implement mandatory controls on greenhouse gasses.

Climate change threatens coldwater reefs
(04/03/2006) Increasing amounts of atmospheric carbon dioxide, driven by the burning of fossil fuels, are dissolving into the oceans, causing them to become slightly more acidic. This change in seawater chemistry could harm deep-sea calcifying animals like corals.
Taking Care of Business: Diapers Go Green
(04/02/2006) Every year some 20 billion disposable diapers are dumped into landfills throughout the United States, generating approximately 3.5 million tons of waste which can take 500 years to biodegrade. Besides creating huge amounts of trash, most disposables are made from materials whitened with chlorine in a process that produces dangerous toxins such as dioxin, furans and other organic chlorines. Cloth diapers--often touted as environmentally superior to disposables--have drawbacks as well, requiring large amounts of water and pesticides, in addition to going through a similar bleaching process. So what's the ecologically responsible alternative? Well, it may come from the land down under. An Australian couple has developed a diaper that is not only biodegradable but serves as a benchmark for green design in that it gives more to the environment than it takes. "gDiapers", as the product is known, was recently awarded the prestigious "Cradle to Cradle Design Certification Award" from MBDC, a design consulting organization that stresses green design. The diaper is the first packaged consumer product to be so honored.
Insects worth $57 billion to US economy
(04/01/2006) A new study says insects are worth at least $57 billion to the American economy. In the April 2006 issue of BioScience, John E. Losey of Cornell University and Mace Vaughan of the Xerces Society for Invertebrate conservation estimate the value of ecological services provided by insects. Looking at just four services--dung burial, control of crop pests, pollination, and wildlife nutrition--Losey and Vaughan calculate that the annual value of insects in these roles is at least $57 billion in the United States.

Is climate change worsening malaria?
(03/21/2006) A widely-cited study published a few years ago said global warming was not contributing to the resurgence of malaria in the East African Highlands, but new research by an international team that includes University of Michigan theoretical ecologist Mercedes Pascual finds that, while other factors such as drug and pesticide resistance, changing land use patterns and human migration also may play roles, climate change cannot be ruled out.
Jungle trekking in Malaysia's Taman Negara
(03/21/2006) Taman Negara is Malaysia's largest and best-known national park. Spanning 4343 square kilometers, the protected forest area is home to some of southeast Asia'apos;apos;s rarest creatures including tigers, the Malaysian tapir, forest elephants, and the Sumatran rhino. Scientists believe that these rainforests may be the oldest on Earth. Untouched by glaciers during recent ice ages, Taman Negara'apos;apos;s forests have remained largely the same for some 130 million years. This stability produces some of the highest levels of biodiversity on Earth: more than 350 species of birds, 14000 species of plants, and 210 species of mammals can be found in Taman Negara.
Disappearing drylands spell trouble says UN
(03/21/2006) According to the United Nations, the continuing degradation of the world'apos;apos;s dryland ecosystems is threatening biodiversity and worsening poverty around the globe.

Climate change due to water vapor from cosmic explosion, not fossil fuels says new theory
(03/13/2006) A controversial new theory attributes climate change not to atmospheric carbon dioxide levels but water vapor. In an unpublished paper, Vladimir Shaidurov of the Russian Academy of Sciences argues that the apparent rise in average global temperature recorded by scientists over the past hundred years could be due to atmospheric changes resulting from the Tunguska Event, a massive explosion over Siberia on the June 30th, 1908 that is thought to have resulted from an asteroid or comet entering the earth's atmosphere and exploding
Harmless frogs gain protection by mimicking toxic species
(03/13/2006) When predators learn to avoid a highly toxic frog, they generalize, and this allows a harmless frog to mimic and be more abundant than a frog whose poison packs less punch, biologists at The University of Texas at Austin studying poison dart frogs in the Amazon have discovered.
Easter Island settled around 1200, later than originally believed
(03/13/2006) New evidence suggests that colonization of Easter Island (Rapa Nui) took place later than originally believed. The research is published in this week's issue of the journal Science. A later settlement supports the premise that human impact on the environment played a key role in the downfall of Easter Island society
