Carbon Forest Protection Payments: Who Gets the Check?

2008-07-16 15:15:23

I have long protected my forests, now where is my money? The Rights and Resources Initiative provides some interesting cautionary advice in new reports, suggesting that rushing to pay for forest protection with carbon funds (REDD) will fail unless land rights in tropical countries,...



The Antioxidant Function of Iodide in Kelp Impacts Coastal Climate

2008-06-02 15:20:57

A new study found that large brown seaweeds, when under stress, release large quantities of inorganic iodine into the coastal atmosphere, where it can contribute to cloud formation, thus influencing coastal climate.



Marine Pollution Control by Seaweed Planting and Composting

A New Model to Protect Biodiversity

2008-04-14 12:37:35

In an era of climate change, pollution, and rapid habitat loss, it?s all too easy for doom and gloom to prevail when discussing conservation issues. However, armed with the right information, it is still possible to create conservation success storie



Logging Road Threatens Biodiversity

2008-04-03 11:33:39

In an investigative report published today by Eyes on the Forest, evidence shows that a new logging road in Riau Province -- strongly indicated as illegally built by companies connected to Asia Pulp & Paper (APP) -- is cutting into the heart of Sumatra's largest contiguous peatland forest,...



Streams are Important Nitrogen Filters in the Landscape

2008-03-31 13:12:04

If you plan to vacation at the beach this summer or open the tap for a clean glass of water, that small stream in your neighborhood may be more important than you think. Why is this? It's because streams are the kidneys of our landscape, helping filter pollutants that drain from their watersheds...



Nitrogen Pollution Boost Plant Growth

2008-03-07 09:36:10

Overview from Laurens Rademakers on Biopact.com*: A study by UC Irvine ecologists finds that excess nitrogen in tropical forests boosts plant growth, countering the belief that such tropical ecosystems would not respond to nitrogen pollution. Surprisingly,...



A New Way to Assess Local Ecosystems Sustainability

2008-02-29 09:08:57

Ecosystems are in flux around the world. Important species are disappearing due to mismanagement and climate change, while invasive new species are appearing. These changes are striking fear into many communities that depend on ecosystems for their livelihood.



Reviving the Coral Reef

2008-02-20 12:37:14

A report from CNN examines a project which uses electricity to revive the dying coral reef in Bali.



Deep-Sea Biodiversity Conservation Needed to Avoid Ecosystem Collapse

2008-02-12 11:53:38

The exploration of the abysses of our planet is one of the last frontiers of ecological research. The dark portion of the biosphere likely hosts millions of undiscovered-yet new species. A global scale study conducted on biodiversity collected down to 8000 m depth reveals for the first time that small...



Climate Influences on Deep Sea Populations

2008-02-07 18:39:25
