(02/20/2008) World fertilizer prices surged by more than 200 percent in 2007, as farmers sought to maximize corn production for ethanol, according to the International Center for Soil Fertility and Agricultural Development (IFDC). Poor African farmers were hardest hit by the increase.
Ancient Amazon fires linked to human populations
(02/20/2008) Analysis of soil charcoal in South America confirms that from a historical perspective, fire is rare in the Amazon rainforest, but when it does occur, it appears linked to human activities. The research, published in Philosophical Transactions of the Royal Society B, is based on dating of soil carbon, which provides a good indication of when fires occurred in Amazonia, according to lead author Mark Bush, head of the Department of Biology at Florida Institute of Technology.
Global warming - not el Nino - drove severe Amazon drought in 2005
(02/20/2008) One of the worst droughts on record in the Amazon was caused by high temperatures in the Atlantic rather than el Nino. The research, published in Philosophical Transactions of the Royal Society B, suggests that human-driven warming is already affecting the climate of Earth's largest rainforest.

Amid accusations of bribery by loggers, Borneo chief's remains to be exhumed
(02/19/2008) Police have announced that they plan to exhume the body of Kelesau Naan to discover the cause of death. The Penan chieftain and passionate activist against logging disappeared in October while checking animal traps. His body was found on December 12th of last year. Several bones were broken, leading some to believe that Naan was assassinated because of his longtime work against loggers. Kelesau Naan had been one of the key figures in the Penan community's fight against logging. He was also a plaintiff and witness in a land rights claim that has been awaiting trial since 1998.
Fire policy is key to reducing the impact of drought on the Amazon
(02/19/2008) Gaining control over the setting of fires for land-clearing in the Amazon is key to reducing deforestation and the impact of severe drought on the region's forests, write researchers in a paper published in Philosophical Transactions of the Royal Society B.
Small Amazon farmers especially vulnerable to climate change
(02/19/2008) Communicating the impact of climate change to small farmers in the Amazon will be key in helping them adapt to higher temperatures, more frequent and intense drought, and greater incidence of forest fires forecast for the region, according to a paper published in Philosophical Transactions of the Royal Society B.

Mysteries of the Great White Shark unveiled
(02/17/2008) The Great White Shark has always been a creature of mystery. The world's largest shark has long fascinated humanity from the novel and film Jaws to recent sumptuous footage of the sharks catching sea lions in Planet Earth. The behemoth, who at times can reach seven meters in length, has also become famous for occasionally attacking swimmers and surfers, though scientists believe the sharks do not intentionally hunt humans. However, the great predator's behvaior and lifecycle remains mostly mysterious to science. Some of these mysteries are just now being unraveled thanks to the Tagging of Pacific Predators (TOPP) program.
Digital maps and mathematical analysis could reduce fishing bycatch
(02/16/2008) Images of dolphins and turtles ensnared in tuna nets are a heart-wrenching reminder of the impact of fisheries on ocean bio-diversity. Known in fisheries science as ‘by-catch,' this killing of non-target species is a complex problem that has resisted easy answers.
Past greenhouse warming events offer clues on future climate change
(02/16/2008) If carbon dioxide emissions from the burning of fossil fuels continue on a "business-as-usual" trajectory, humans will have added about 5 trillion metric tons of carbon to the atmosphere by the year 2400. A similarly massive release of carbon accompanied an extreme period of global warming 55 million years ago known as the Paleocene-Eocene Thermal Maximum (PETM).

Only 4% of the ocean is pristine according to first oceanic map of human-impact
(02/14/2008) There is a much used adage regarding the ocean that goes something like this: we know more about our solar system than our ocean. Whether or not one believes this to be true (less than 5% of the ocean has been explored), a group of over twenty researchers, by agglomerating the available information on the oceans, have created a large-scale image of the ocean's health.

The concepts of "nature" in Iceland and the U.S.
(02/13/2008) I don't remember how we traveled from the airport to the village. I remember sitting on a bus from Reykjavik to the surrounding countryside, but the timeline from the States to that small Nordic country fails to make sense. This is fitting. It's a habit of mine to arrive at airports early. The airport implies states of both "coming" and "going", yet in truth, you arrive at neither until the moments of physically boarding a plane. Everything in between is pure luxury- seconds, minutes, and sometimes hours of detachment from linear time. I require the freedom to daydream. I wander around. I consider where people might be going. I give some thought to buying an expensive sandwich, the mediocrity of which will never justify the purchase.
Malaysia announces $103B development plan for Borneo island

How activists and scientists saved a rainforest island from destruction for palm oil
(02/12/2008) In mid-January, Mongabay learned that the government of Papua New Guinea had changed its mind: it would no longer allow Vitroplant Ltd. to deforest 70% of Woodlark Island for palm oil plantations. This change came about after one hundred Woodlark Islanders (out of a population of 6,000) traveled to Alotau, the capital of Milne Bay Province, to deliver a protest letter to the local government; after several articles in Mongabay and Pacific Magazine highlighted the plight of the island; after Eco-Internet held a campaign in which approximately three thousand individuals worldwide sent nearly 50,000 letters to local officials; and after an article appeared in the London Telegraph stating that due to deforestation on New Britain Island and planned deforestation on Woodlark Island, Papua New Guinea had gone from being an eco-hero to an 'eco-zero'.

Photo: Litter of naked mole rats born in time for Chinese New Year
(02/10/2008) The Bronx Zoo introduces some of its favorite little herbivore critters — a new litter of naked mole rat "pups" arriving just in time to celebrate the Lunar New Year — Year of the Golden Rat. Naked mole rats can be seen everyday at their World of Darkness exhibit. Native to the tropical grasslands of Kenya, Somalia, and Ethiopia, the Zoo's habitat gives a visual "slice of life" in a naked mole rat colony. Literally, the exhibit was designed to go deep underground to provide Zoo-goers with a view of this complex tunneling-system. Naked mole rats have a social system similar to bees with a queen (the only reproductive female), workers, and breeders.
