Dried-up Colorado takes toll on giant Mexican fish
(06/08/2008) The Colorado River vanishes before it reaches the Sea of Cortez in all but the wettest years. Companies in California and the southwestern U.S. have diverted its once-vibrant flow to quench their thirst for water and power. Now, a new study in the April 2008 issue of the journal Biological conservation reports that the dwindling of this major artery has changed the way some marine fish in the Gulf of California grow and develop.

Amazon beef producer creates eco-certified meat product with help of scientists
(06/08/2008) Independencia Alimentos SA, Brazil's fifth-largest beef producer, will create an "eco-certified", branded beef product from the Amazon's Xingu region. Certification will be based on criteria established by Alian?a da Terra, an Brazilian NGO that seeks to improve the environmental performance of ranchers and beef producers in the world's largest rainforest. The new beef product will include a per-kilo "ecosystem service fee" — calculated with the help of scientists at the Woods Hole Research Center — to facilitate a financial reward for the producer's environmental stewardship.
Big Farms Can Make the Leap to Organic Farming, Study Suggests

Scientists aim to catalogue tropical island from mountaintops to seafloor
(06/04/2008) Scientists are launching an effort to catalogue a complete tropical ecosystem, the first time anyone has attempted such an ambitious undertaking. Led by researchers at the University of California, Berkeley, a U.S.-French team plans to collect DNA "barcodes" for every animal, plant, and fungus on the small island of Moorea in the South Pacific, scouring habitats from coral reefs to high-reaching cloud forests. The island could eventually serve as a model for how ecosystems respond to stresses such as climate change, invasive species, and pollution.
Diversity in streams may brace Chinook salmon for climate change
(06/03/2008) Chinook salmon face a one-two punch. They have disappeared from several rivers in the western U.S. largely because of human interventions and some populations are threatened or endangered. Numbers of Chinook in California's Central Valley have dwindled by 88 percent in the past five years, a loss that closed fisheries for 2008 and may cost California's economy $167 million, according to the state Department of Fish and Game. On top of all this looms a second impact: These salmon will be in hotter water still because of climate change.
Brazil's new environmental minister blames ranchers for surge in Amazon deforestation
(06/03/2008) Deforestation in the Brazilian Amazon rose significantly in April 2008 according to Carlos Minc, Brazil's newly appointed environment minister.
Food miles are less important to environment than food choices, study concludes
(06/02/2008) Shoppers concerned about the environment should not place "buying local" at the top of their list of priorities when purchasing food, according to a study published online on April 16 in the journal Environmental Science & Technology. The fuel burned in transporting food items from farm to marketplace creates just a small percentage of the total greenhouse gas emissions associated with the food. Instead, consumers should shift their diets to include more foods that require less energy to produce in the first place.
Papua New Guinea's rainforests disappearing faster than thought
(06/02/2008) Logging is taking a heavy toll on the forests of Papua New Guinea, suggests a new study. Using satellite images to reveal changes in forest cover between 1972 and 2002, researchers from the University of Papua New Guinea and the Australian National University found that Papua New Guinea (PNG) lost more than 5 million hectares of forest over the past three decades — total forest cover declined from 38 million hectares in 1972 to 33 million hectares in 2002. Worse, deforestation rates may be accelerating, with the pace of forest clearing reaching 362,000 hectares (895,000 acres) per year in 2001. The study warns that at current rates 53 percent of the country's forests could be lost or seriously degraded by 2021.
Cellulosic biofuels may be viable alternative to gas within 5 years
(06/02/2008) A new institute in the San Francisco Bay Area is seeking to make cellulosic biofuel an economically viable alternative to corn ethanol and gasoline within the next five years. The Joint BioEnergy Institute (JBEI), a partnership between three national laboratories and three Bay Area universities, was formed in June 2007 after the U.S. Department of Energy awarded the institute a $125 million grant to develop better methods for making liquid biofuels from the natural cellulose in trees and grasses. JBEI researchers expect cellulosic biofuels to yield more energy, produce less greenhouse gases, and have less impact on the environment than other alternatives to gasoline, such as corn ethanol.

Pictures of uncontacted Indian tribe in the Amazon (update)
(05/30/2008) A helicopter fly-over of a remote part of the Brazilian Amazon captured photos of what is believed to be one of the world's last uncontacted tribes, reports a group that works to protect indigenous peoples. Images released by London-based Survival International show an angry response from members of the tribe — warriors in red war paint took aim at the chopper with bows and arrows. The photos, taken by José Carlos dos Reis Meirelles Junior of FUNAI, the Brazilian government's Indian affairs department, were released to bring attention to encroachment on indigenous lands near the border with Peru. Brazil says illegal loggers from Peru are threatening tribes deep in the Amazon rainforest.

50 years after the blast: Recovery in Bikini Atoll's coral reef
(05/27/2008) Fifty years after atomic bombs rocked Bikini Atoll and pulverized its coral reef, the lagoon again boasts a flourishing coral community. Scientists diving in the two-kilometer-wide Bravo Crater, created in 1954 by a blast 1,000 times stronger than the bomb dropped on Hiroshima, Japan, found a thriving habitat with treelike corals 30 centimeters (one foot) thick. The study shows that coral reefs can recover from profound damage?when humans leave them alone.

Why is there soot on the snowpack?
(05/22/2008) This fall, suitcase-sized air samplers will sprout throughout the Sierra Nevada. The air monitoring stations will be installed by researchers at the University of California, Davis, as part of a contract approved by the California Energy Commission (CEC) during its May 7 meeting. The researchers hope to learn whether the pollutants affecting the state's climate are coming from local sources or from transPacific sources like Asia, said Public Interest Energy Research (PIER) manager Guido Franco. The sensitive new devices will measure the amount of air pollution in the area and identify the makeup of the particles, Franco told the commission. Chemical detective work will then reveal their sources.

Group files for ESA protection of 681 species in 12 states
(05/21/2008) On March 19th WildEarth Guardians filed a lawsuit to place 681 species under the Endangered Species Act. Dr. Nicole Rosmarino, wildlife program director for the environmental group, says These 681 species represent species in only 12 states, include no subspecies, and are only the "most imperiled" of the United State's threatened species. Rosmarino estimates that in total there are 6,000-9,000 endangered species in the United States today. Mongabay.com recently caught up with Dr. Rosmarino regarding this landmark lawsuit and the reasoning for it.

Culling the kangaroos may be the only option for saving some of these grassland species from extinction.
Half of oil palm expansion in Malaysia, Indonesia occurs at expense of forests
(05/20/2008) More than half of the oil palm expansion between 1990 and 2005 Malaysia and Indonesia occurred at expense of forests, reports a new analysis published in the journal conservation Letters. Analyzing data from the United Nations Food and Agriculture Organization, Lian Pin Koh and David S. Wilcove of Princeton University found that 55-59 percent of oil palm expansion in Malaysia and at least 56 percent of that in Indonesia occurred at the expense of forests. Given that oil palm plantations are biologically impoverished relative to primary and secondary forests, the researchers recommend restricting future expansion to pre-existing cropland and degraded habitats.
