• 2013 PCB dredging on the Hudson

    The U.S. Environmental Protection Agency today announced that more than 612,000 cubic yards of river bottom sediment contaminated with PCBs were removed from the upper Hudson River during 2013, exceeding the annual goal of 350,000 cubic yards for this historic dredging project. This is similar to the amount dredged in 2012 when more than 650,000 cubic yards were removed. The Superfund cleanup required by the EPA calls for the dredging of approximately 2.65 million cubic yards of PCB-contaminated sediment from a 40-mile stretch of the upper Hudson River between Fort Edward and Troy, New York. The project began in 2009 and is about 73% complete, putting the dredging on track to be finished in two years. To date, about 1.9 million of the 2.65 million cubic yards million have been removed. Filling of previously dredged areas with clean sand and gravel will continue over the next several weeks, weather permitting. About 280 local area contractors, subcontractors, vendors and suppliers have provided goods or services related to Hudson River dredging. >> Read the Full Article
  • Sea stars wasting away on both U.S. coasts

    Evidence suggests that we are at the onset of another sea star wasting event. Sea stars on both the east and west coasts of the United States have fallen victim to a wasting disease that overcomes the Pisaster ochraceus in a matter of days once an initial lesion appears. The disease, while currently not understood, is rapidly transmitted amongst the population once it takes hold. On the west coast studies show that the disease is bacterial but on the east coast it is viral. Both result in a similar disintegration of the flesh within a very short period of time. >> Read the Full Article
  • Scientists start to tap marine microbes for biotech use

    [PARIS] The hot, brackish waters of French Polynesia’s lagoons in the Pacific could harbour microbes with huge commercial potential, including for drug creation or to produce alternatives to plastics, say researchers. The extreme conditions found in some Polynesian aquatic ecosystems, which are often characterised by high temperatures and salinity, mean that unique marine bacteria have evolved there. >> Read the Full Article
  • The Juncture of Politics and the Environment

    When announcing his plan to kick-start the U.S. economy in the midst of the Great Depression, Franklin D. Roosevelt famously declared that the country had "nothing to fear but fear itself." In just 100 days, through a flurry of legislation and investment, his government dragged the country up off its knees – a towering political achievement. >> Read the Full Article
  • Do dams bring more harm or more good?

    As China forges ahead with its goal to generate 120,000 megawatts of renewable energy by 2020, they are damming more and more rivers. According to China, this is a safe strategy that will curb pollution, control floods, and minimize climate change. Conservationists and scientists across the globe however, disagree. >> Read the Full Article
  • Bolivia, Madagascar, China see jump in forest loss

    Loss of forest cover increased sharply in Bolivia, Madagascar, and Ecuador during the third quarter of 2013, according to an update from NASA scientists. NASA's Quarterly Indicator of Cover Change (QUICC), a MODIS satellite-based product that underpins Mongabay.com's Global Forest Disturbance Alert System (GloF-DAS), picked up strong deforestation signals in the three tropical countries between July 1 and September 30, 2013: Bolivia (167 percent increase in deforestation relative to the year-earlier period), Madagascar (126 percent), and Ecuador (38 percent). Outside the tropics, Pakistan, China, the United States, and Argentina appeared to experience an increase in forest and woodland disturbance. >> Read the Full Article
  • Safe passage at last for the Pronghorn

    U.S. Highway 191 in Trapper's Point, Wyoming is safer today for motorists and pronghorns alike as a result of a newly built 8-part overpass/underpass system designed to facilitate the travel and migration of local populations of pronghorn, mule deer, moose, elk and other wildlife safely over the highway. While the overpass was completed in time for last year’s migration, the pronghorn were hesitant to use the system last year making researchers nervous. However, this year the pronghorn were less confused by the alteration and used the passages willingly. >> Read the Full Article
  • Relating demographics and social systems to declines in Asian Great Ape population

    Catastrophic declines in wild populations of African gorilla and chimpanzees due to disease outbreaks have been reported in recent years, yet similar disease impacts are rarely identified for the more solitary Asian great apes, or for smaller primates. Researchers led by Sadie Ryan, Assistant Professor at the State University of New York College of Environmental Science and Forestry has recently published a study centered on the interaction between the social system and demographics of different primate species to determine if any of these behaviors or realities predispose them to potentially lethal pathogens. Through this study the researchers have identified interactions between social structure, demography, and disease transmission modes that create "dynamic constraints" on the pathogens that can establish and persist in primate host species with different social systems. >> Read the Full Article
  • Chickens to benefit from surge in biofuels popularity

    Chickens could be the unexpected beneficiaries of the growing biofuels industry, feeding on proteins retrieved from the fermenters used to brew bioethanol, thanks to research supported by the Engineering and Physical Sciences Research Council (EPSRC). It has long been known that the yeasty broth left over after bioethanol production is nutritious, but it has taken a collaboration between Nottingham Trent University and AB Agri, the agricultural division of Associated British Foods, to prove that Yeast Protein Concentrate (YPC) can be separated from the fibrous cereal matter. >> Read the Full Article
  • Falling fruit: A global collaborative foraging map

    Foraging for fruit just got easier, with a map bringing together foraging data around the world. Thought to be the first effort on such a large scale, Falling Fruit is a massive, collaborative urban harvesting map that aims to reduce waste while reconnecting people to their environments. Around 500 species are currently shown on the map, across locations as diverse as Australia, India, Mauritius, Israel and the Netherlands. It's just launched in the UK, collating more than 30 isolated maps from across Britain. >> Read the Full Article
