Do dams bring more harm or more good?
November 4, 2013 09:01 AM - Editor, ENN
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.
Safe passage at last for the Pronghorn
November 1, 2013 04:56 PM - Robin Blackstone, ENN
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.
Relating demographics and social systems to declines in Asian Great Ape population
November 1, 2013 10:53 AM - Robin Blackstone, ENN
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.
Falling fruit: A global collaborative foraging map
November 1, 2013 08:58 AM - Ruth Stokes, The Ecologist
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.
Sandy’s path of destruction felt in the Caribbean too
October 29, 2013 04:17 PM - Robin Blackstone, ENN
Last year at this time much of the United States eastern seaboard was closely monitoring Super Storm Sandy. Hour by hour people watched with horror as she blew across the Dominican Republic, Haiti, Cuba and the Bahamas ultimately charging up the Atlantic, swinging west to crash into the Mid-Atlantic states at full force. Damage to New York and New Jersey was extensive to be sure, but the larger populations and greater affluence to the north have largely overshadowed recovery of the Caribbean nations.
Mercury Sediment Carried Forth by California Floods
October 29, 2013 01:59 PM - Robin Blackstone, ENN
Mercury contamination in sediment has been a big concern in the Central Valley lowland areas of California. But associate researcher from the University of California, Michael Singer has unearthed new information and considerations utilizing modern topographic datasets and modeling to track mercury-laden sediment. Singer hypothesizes that the progradation process resulting from 10-year flooding events within the valleys below the Sierra Nevada Mountains are the key to understanding and tracking the presence of mercury. Singer has connected the mercury amalgamation process, which was used to extract gold from the mountains during the 19th century with the current high incidence of mercury in regional delta sediment.
Researchers link melting Arctic Sea ice to increased summer rainfall in Northwest Europe
October 29, 2013 10:54 AM - Editor, ENN
A new report conducted by researchers at the University of Exeter offers insight into why Northwest Europe experienced extraordinarily wet summers between 2007 and 2012, stating that melting sea ice and changes with the jet stream are to blame for these soggier summers. Jet streams are currents of strong winds high in the atmosphere that steer weather systems and their rain. Normally in summer the jet stream lies between Scotland and Iceland and weather systems pass north of Britain. However, the jet stream has shifted south in recent summers, bringing unseasonable wet weather to Britain and northwest Europe. The cause for the jet stream shift is being attributed to the loss of Arctic sea ice.

Anthony Martin, paleontologist at Emory University in Atlanta, GA recently discovered two fossilized footprints presumably made by a landing bird during the Early Cretaceous period at Dinosaur Cove in Victoria, Australia. This discovery marks the oldest known bird tracks in Australia.
GM Crops Causing a Stir in Washington State, Mexico, and Hawaii
October 28, 2013 10:30 AM - Sophie Wenzlau, Worldwatch Institute
Courts, councils, and voters across North America are weighing in on genetically modified (GM) crops this month In Washington state, voters are beginning to cast ballots in favor of or opposing Initiative 522, which would mandate that all GM food products, seeds, and seed stocks carry labels in the state.
The People’s Choice: Americans Would Pay to Help Monarch Butterflies
October 28, 2013 08:47 AM - Ethan Alpern, USGS
Americans place high value on butterfly royalty. A recent study suggests they are willing to support monarch butterfly conservation at high levels, up to about 6 ½ billion dollars if extrapolated to all U.S. households. If even a small percentage of the population acted upon this reported willingness, the cumulative effort would likely translate into a large, untapped potential for conservation of the iconic butterfly.
