Study reveals that nitrogen fertilizers deplete soil organic carbon
(10/30/2007) The common practice of adding nitrogen fertilizer is believed to benefit the soil by building organic carbon, but four University of Illinois soil scientists dispute this view based on analyses of soil samples from the Morrow Plots that date back to before the current practice began.

(10/30/2007) An inquiry by The Wall Street Journal prompted the Forest Stewardship Council (FSC), an environmental body that runs a widely accepted "green" labeling system for forestry products, to revoke certification for a Singapore-based Asia Pulp & Paper Co. (APP) project on the Indonesian island of Sumatra.

Despite fire risk, more Americans building near forests
(10/29/2007) While much of the world is seeing an urbanization trend, U.S. housing density around national forests is expected to rise by 2050, reports a study from the U.S. Forest Service. The shift could put more people at risk of devastating forest fires and increase pressure on forests and the services they provide.
Iguanas listen to birds to avoid predators
(10/29/2007) As the world's only sea-feeding lizard, Galapagos Marine Iguanas have long held a unique place in the animal kingdom. While most of their life is spent on land, these lizards forage the seas for their staple food: algae. Now, new research has provided this species with another distinction: although the Galapagos Marine Iguana is mute, it recognizes and utilizes the alarm call of the Galapagos Mockingbird. This is the first instance of a non-vocal species eavesdropping on another species' calls. Both the iguana and mockingbird fall prey to the Galapagos hawk, so by recognizing the mockingbird's warning the iguanas gain important information on avoiding predation.
Scientists find treatment for killer frog disease
(10/29/2007) New Zealand scientists have found a treatment for a disease blamed for the death of millions of amphibians worldwide, according to a report from BBC News. However, at best, the cure would only be applicable to captive populations. The disease is killing many amphibians in apparently pristine habitats.
Bears pressured by development in the Canadian Rockies
(10/29/2007) The southern Canadian Rockies are still home to the most diverse assemblage of carnivores in North America, but a new report released today by the Wildlife conservation Society Canada (WCSC) says booming development there could threaten them without careful planning and the implementation of conservation safeguards.
Avoided deforestation beats timber, palm oil, in tax revenue for Indonesia

Parasites a key to the decline of red colobus monkeys in forest fragments
(10/25/2007) Forest fragmentation threatens biodiversity, often causing declines or local extinctions in a majority of species while enhancing the prospects of a few. A new study from the University of Illinois shows that parasites can play a pivotal role in the decline of species in fragmented forests. This is the first study to look at how forest fragmentation increases the burden of infectious parasites on animals already stressed by disturbances to their habitat.
Climate sensitivity to rising CO2 levels still uncertain
(10/25/2007) Climate sensitivity to increasing concentrations of greenhouse gases is still largely uncertain and researchers will likely not be able to further refine their estimates on future climate scenarios, say two University of Washington scientists writing in this week's issue of the journal Science.

conservationists need to work with, not against, rural poor
(10/24/2007) Rural populations have long been demonized by conservationists, but this is changing. Increasingly, conservation groups see that without the support of rural populations, protected areas can in places be little more than ineffective "paper parks". As such, today community involvement is viewed as a critical part of any conservation program, whether it be protecting biodiversity, slowing deforestation, curtailing illegal logging and poaching, or establishing reserves.
Google Earth adds endangered species info
(10/24/2007) Google Earth users can now learn about 100 of the world's most endangered species through a new KML developed by the Zoological Society of London's EDGE of Existence program.
North Atlantic carbon sinks absorbing less CO2
(10/23/2007) The capacity of the North Atlantic ocean to absorb atmospheric carbon dioxide (CO2) has declined significantly since in the mid 1990s, report researchers from the University of East Anglia. The findings raise concerns that oceans may be slowing their uptake of CO2, potentially worsening the climate impact of greenhouse gas emissions.
Honda sees no future for plug-in hybrid vehicles
(10/23/2007) Honda Motor Co. Chief Executive Takeo Fukui said plug-in hybrid gasoline-electric vehicles offered too few environmental benefits to be worth pursing for the Japanese car company, according to the Wall Street Journal. Instead Fukui suggested that improved batteries would be better used for electric vehicles.
Does palm oil alleviate rural poverty in Malaysia?
(10/23/2007) While it is often argued that the economic benefits of oil palm plantations outweigh the environmental costs of converting biodiverse ecosystems to monocultures, new analysis suggests that the role of plantations in reducing rural poverty may be overstated.
2007 Amazon fires among worst ever
(10/22/2007) By some measures, forest fires in the Amazon are at near-record levels, according to analysis Brazilian satellite data by mongabay.com. A surge in soy and cattle prices may be contributing to an increase in deforestation since last year. Last year environmentalists and the Brazilian government heralded a sharp fall in deforestation rates, the third consecutive annual decline after a peak in 2004. Forest loss in the 2006-2007 season was the lowest since record-keeping began in the late in 1970s. While the government tried to claim credit for the drop, analysts at the time said that commodity prices were a more likely driver of slow down: both cattle and soy prices had declined significantly over the previous months.
Carbon sinks failing to keep up with emissions
(10/22/2007) Atmospheric carbon dioxide (CO2) growth has increased 35 percent faster than expected since 2000, report scientists writing in Proceedings of the National Academy of Sciences. Worryingly, more than half the increase came from a decreased efficiency of natural land and ocean sinks to absorb CO2 from the atmosphere. The reminder came from a slowing in the efficiency of use of fossil fuels.
Amazon plant diversity still a mystery
(10/21/2007) The Amazon is one of the few places on the earth that still evokes an accurate sense of mystery. While the Taiga, Antarctica, and Sahara may compare to the Amazon in wilderness size, none hold the same mystique of unknown species. It is believed that one third of the world's species inhabits this tropical rainforest. The only region comparable in mystery (though not in species) may be the world's oceans.
Brazil to search for oil in the Amazon
(10/21/2007) Brazil's plan to seek oil in the Western Amazon has upset environmentalists, reports the Associated Press (AP).
