U.S. EPA Delegates Clean Water Act Authority to Northern California Tribe

The U.S. Environmental Protection Agency (EPA) recently announced that Dry Creek Rancheria in Sonoma County, Calif., has gained authority to administer its own water quality programs under the federal Clean Water Act.

Should Corporate Crime Pay Punitive Damages Based on Company's Worth?

If courts were able to award appropriate punitive damages that punish wrongdoers at a level tied to a company's financial worth, then businesses big and small would be at risk of being put out of business by punitive damages, thus deterring unconscionable offenses and bad behavior in the first place.

Wildlife Conservation Society Uncovers Record Number of Jaguars in Bolivia

In a new camera trap survey in the world’s most biologically diverse landscape, researchers for the Wildlife Conservation Society have identified more individual jaguars than ever before.

Leaf Litter Ants Advance Case for Rainforest Conservation in Borneo

Studies of ant populations in Borneo reveal an unexpected resilience to areas of rainforest degraded by repeated intensive logging, a finding which conservationists hope will lead governments to conserve these areas rather than allow them to be cleared and used for cash crop plantations.

Green Roofs Save Money, Energy but Challenge Texas Plants

When contractors talk of green buildings, they mean environmentally-friendly and energy saving. Add agricultural experts in the plans, and “green” also means plants – vibrant ornamental grasses, shrubs and flowers in park-like settings on the roofs of multistoried office buildings in cities.

No More Buying Cars but Sharing Them?

Lower emissions, less noise, more quality of life – all good reasons to turn to electricity where mobility is concerned. If the EU has its way, we will all be driving only electric cars in the major cities of Europe by the year 2050. A beautiful goal, but experts are going even further than that: citizens can forego a car of their own and share electric vehicles.

Two New Bee Species from Central and South America

Smithsonian scientists have discovered two new, closely related bee species: one from Coiba Island in Panama and another from northern Colombia. Both descended from of a group of stingless bees that originated in the Amazon and moved into Central America, the ancestors of Mayan honeybees. The presence of one of these new species on Coiba and Rancheria Islands, and its absence from the nearby mainland, is a mystery that will ultimately shed light on Panama's history and abundant biodiversity.

New Research Reveals Herbivorous Fish Like Eating Meat

NWO researcher Liesbeth Bakker made this discovery during her research into the food preferences of fish. The discovery turns our current understanding of the relationships between plants and animals on its head.



Homebuilder to Pay Clean Water Act Penalty, Implement Company-wide Stormwater Controls

The Ryland Group Inc. will pay a civil penalty of $625,000 to resolve alleged Clean Water Act violations at its construction sites.

Household Washing Machines: A Major Source of Microplastic Pollution

Scientists are reporting that household washing machines seem to be a major source of so-called "microplastic" pollution that they now have detected on ocean shorelines worldwide.

Forest Owners and States Ask Supreme Court to Reverse Ninth Circuit on Forest Roads

A bi-partisan, geographically diverse group of twenty-six state Attorneys General joined forest owners and industry groups in filing briefs  asking the U.S. Supreme Court to reverse the 9th Circuit Court of Appeals' ruling that rainwater runoff from forest roads used for timber harvest is a "point source" of water pollution under the Clean Water Act.

Researchers Determine Fracking Proximity

Natural gas mining has drawn fire recently after claims that hydraulic fracturing, an increasingly popular technique for tapping hard-to-reach reservoirs, contaminates groundwater. Surface lakes, rivers and streams may also be at risk.

Clustered Hurricanes Reduce Impact on Ecosystems

New research has found that hurricane activity is 'clustered' rather than random, which has important long-term implications for coastal ecosystems and human population. The research was carried out by Professor Peter Mumby from The University of Queensland Global Change Institute and School of Biological Sciences, Professor David Stephenson and Dr. Renato Vitolo (Willis Research Fellow) at the University of Exeter's Exeter Climate Systems research centre.

New GIS Systems Can Calculate Energy Produced By Solar Panel Roofs

Scientists from the University of Gothenburg, Sweden, have launched a tool that uses the actual conditions to determine the maximum possible magnitude of solar incidence - in a whole town, a neighbourhood, or a particular roof.

Yale Researchers Discover U.S. Rivers and Streams Saturated with Carbon

Rivers and streams in the United States are releasing enough carbon into the atmosphere to fuel 3.4 million car trips to the moon, according to Yale researchers in Nature Geoscience. Their findings could change the way scientists model the movement of carbon between land, water and the atmosphere.

Determine the Solar Efficiency of Your Roof

It is becoming more and more common to install solar panels on roofs in order to obtain green electricity, but not all roofs are equally suitable.

EPA Marks 25th Anniversary of EPCRA

This year marks 25 years since the passage of the federal Emergency Planning and Community Right-to-Know Act (EPCRA). The act was passed in 1986 as a part of the reauthorization for Superfund. EPCRA has played a significant role in protecting people’s health and the environment by providing communities and emergency planners with area-specific information on toxic chemical releases.

Chemical warfare on the reef: How certain seaweed species harm corals

Scientists for the first time have identified and mapped the chemical structure of molecules used by certain species of marine seaweed to kill or inhibit the growth of reef-building coral. Chemicals found on the surfaces of several species of seaweed have been shown to harm coral, suggesting that competition with these macroalgae could be a factor in the worldwide decline – and lack of recovery – of coral reefs.

Turning Forest Refuse into Biochar

Students at the University of Washington have teamed up on a startup that promises to turn slash piles of forest refuse into biochar, a crumbly charcoal-like product for farmers that helps their soil hold water and nutrients. Biochar is not technically a fertilizer, but often improves yield for farmers.

Ecosystem Management Must Consider Human Impact

For a long time, ecologists have believed—and others accepted—that when it comes to whether a land mass is covered with forests or grasslands, climate controls the show. They thought that the amount of rain, temperature and frequency of wildfires determine whether the ground will be covered with trees or grasses.
