An interview with primate researcher Dr. Karen Strier: America's largest monkey recovering after brush with extinction
(01/10/2008) The Atlantic forest of Brazil boasts South America's largest primates, the Southern and Northern Muriqui. The muriqui are unique among all primates, because they are not territorial and do not display aggressive behvaior. The IUCN has classified the Southern Muriqui as endangered, while the Nothern Muriqui is critically endangered. Dr. Karen Strier has studied the Northern Muriqui in the field for twenty-five years. A professor of zoology and anthropology at the University of Madison Wisconsin, she is the author of Faces in the Forest: the Endangered Muriqui Monkeys of Brazil and a new textbook entitled Primate behvaioral Ecology.

Human activity is killing coral reefs in the Caribbean
(01/08/2008) A wide and thorough study of the Caribbean's coral reefs--including 322 sites in 13 countries--has shown that the main indicator of coral destruction in the Caribbean is the proximity of human populations: the larger the population the greater the deterioration of the reefs. Contributing factors are numerous, but the study showed that coastal development causes the most damage to coral reefs and fish populations, because of increased sewage and fishing pressure; while proximity to agriculture results in macroalgae due to runoff of agricultural chemicals.

(01/08/2008) In a meeting with representatives of environmental groups Rainforest Relief and New York Climate Action Group, Parks Commissioner Adrian Benepe unveiled a plan to phase out the use of hardwoods logged from the rainforests of the Amazon, which the agency uses for benches, boardwalks and the decking of bridges in the thousands of parks and areas overseen by the department. Celia Peterson, director of the Specification Office of NYC Parks, stated that as of last month, Parks will no longer specify tropical hardwoods for benches.
Photos: Hippos threatened in Africa
(01/07/2008) As the sun sets on the Luangwa River in Zambia, a male hippo throws its mouth open in a yawn as wide as a canyon.

Scientists propose conservation areas for the unique island of Sulawesi
(01/06/2008) Little-known Sulawesi may be the world's most strangely shaped island: with four large peninsulas jutting outward, the island could either resemble a mangled lower-case 'k' or an upside-down emaciated mermaid—depending on one's perspective. However when Dr. Charles Cannon states that the island is "one of the most unique spots on Earth", he is not referring to Sulawesi's shape but its ecology.

Lack of A-bomb signatures suggest 50 years of shrinking Tibetan glaciers
(12/30/2007) Ice cores drilled last year from the summit of a Himalayan ice field lack the distinctive radioactive signals that mark virtually every other ice core retrieved worldwide. That missing radioactivity, originating as fallout from atmospheric nuclear tests during the 1950s and 1960s, routinely provides researchers with a benchmark against which they can gauge how much new ice has accumulated on a glacier or ice field.

Will carbon credits-for-forests scheme be undermined by carbon negative bioenergy?
(12/18/2007) The Indonesian government has signed an agreement with energy giant Total E&P Indonesia on a carbon capture and storage scheme that could eventually lead to the development of carbon negative bioenergy production in the southeast Asian country, reports Biopact. The deal raises fears that feedstock for production could lead to large-scale deforestation of the country's remaining forests and undermine efforts to push forest conservation-for-carbon credits (or REDD) initiatives.
Study shows that sea turtles can recover
(12/18/2007) conservation of sea turtle nesting sites is paying off for the endangered reptiles, reports a new study published this week in the journal Global Ecology and Biogeography. A team of researchers led researchers from IUCN and conservation International found that green turtle (Chelonia mydas) nesting on four beaches in the Pacific and two beaches in the Atlantic have increased by an four to fourteen percent annually over the past two to three decades as a result of beach protection efforts.
Rainforest destruction increasingly driven by corporate interests, not poverty
(12/18/2007) Tropical deforestation is increasingly enterprise-driven rather than the result of subsistence agriculture, a trend that has critical implications for the future of the world's forests, says Dr. Thomas Rudel, a researcher from Rutgers University. As urbanization and government-sponsored development programs dwindle in the tropics, industrial logging and conversion for large-scale agriculture -- including oil palm plantations, soy farms, and cattle ranches -- are ever more important causes of forest destruction.
