Arctic insects and spiders can survive colder temperatures than thought
Arctic bugs can survive in frozen ground as cold as -27Â°C, scientists have revealed. It is the first time higher-order invertebrates such as spiders, flies and beetles have been found coping in direct exposure to such cold temperatures. Previous lows were between just -5Â°C and a little below -10Â°C. The research, published in the Journal of Thermal Biology, suggests they may be more resilient to climate change than first feared. >> Read the Full Article
When Forests Aren't Really Forests: The High Cost of Chile's Tree Plantaions
At first glance, the statistics tell a hopeful story: Chileâ€™s forests are expanding. According to Global Forest Watch, overall forest cover changes show approximately 300,000 hectares were gained between 2000 and 2013 in Chileâ€™s central and southern regions. Specifically, 1.4 million hectares of forest cover were gained, while about 1.1 million hectares were lost. On the ground, however, a different scene plays out: monocultures have replaced diverse natural forests while Mapuche native protesters burn pine plantations, blockade roads and destroy logging equipment. At the crux of these two starkly contrasting narratives is the definition of a single word: â€œforest.â€ >> Read the Full Article
Toxic Algae Scare Prompts Backlash Against Farms
What do a no-drink order in Toledo and a backlash against factory farming have in common? A lot, as it turns out. Residents of Ohio's fourth-largest city were advised for multiple days earlier this month to refrain from drinking their tap water because it had been contaminated by toxic algae. As residents struggled to deal with their contaminated water supply, the culprit behind the problem became readily apparent: factory farms. The Ohio Agriculture Advisory Council (OAAC) is proposing a regulatory crackdown that could forever change industrial farming practices in this Midwestern state. >> Read the Full Article
Plant Language
A Virginia Tech scientist has discovered a potentially new form of plant communication, one that allows them to share an extraordinary amount of genetic information with one another. The finding by Jim Westwood, a professor of plant pathology, physiology, and weed science in the College of Agriculture and Life Sciences, throws open the door to a new arena of science that explores how plants communicate with each other on a molecular level. It also gives scientists new insight into ways to fight parasitic weeds that wreak havoc on food crops in some of the poorest parts of the world. >> Read the Full Article
What can we learn from the California Rim Fire?
August 17, 2014 will mark the one year anniversary of the Rim Fire in the California Sierra Nevadas. It was dubbed the Rim Fire due to its proximity to the Rim of the World scenic lookout. The third largest wildfire in Californiaâ€™s history, it burned 257,000 acres of land in Stanislaus National Forest and the western edge of Yosemite National Park, in addition to private land in neighboring counties. It cost more than $127 million to contain, and included more than $50 million in property damage. In the early hours of the fire, a deer hunter was rescued. After the hunter was taken to safety by helicopter, investigators interviewed him to see if he witnessed anything. He told them that he had slipped and caused a rock slide that may have ignited the dry vegetation. As time went on, his story changed several times, even blaming it on marijuana growers. Finally, as the fire had been raging for several weeks, he finally told the real story. >> Read the Full Article
Engineering Fruit Flies May Help Crops
We've genetically-modified crops to enhance desired traits such as increased resistance to herbicides or pesticides. Nonetheless, pests still infest crops around the world. In an attempt to control these pests, scientists have turned to genetically engineering the pests themselves! >> Read the Full Article
The cost of marine debris
Marine debris has many impacts on the ocean, wildlife, and coastal communities. A NOAA Marine Debris Program economic study released today shows that it can also have considerable economic costs to residents who use their local beaches. The study found that Orange County, California residents lose millions of dollars each year avoiding littered, local beaches in favor of choosing cleaner beaches that are farther away and may cost more to reach. Reducing marine debris even by 25 percent at beaches in and near Orange County could save residents roughly $32 million during three months in the summer. >> Read the Full Article
Bottling Water from Drought Stricken Areas
The bottled water industry has grown exponentially the past few decades despite the fact tap water in the United States is generally safe. Never mind the fact bottled water producers have had more than their fair share of safety issues: bottled water has become accepted by consumers. While companies such as NestlÃ© insist they are taking responsibility for water stewardship and recycling, they also bottle their water at dubious sources, including those in drought stricken regions. >> Read the Full Article
The importance of maintaining seagrass
Seagrass meadows provide the ideal place for young fish to thrive, say NERC-funded scientists researching the importance of these habitats for commercial fishing. Globally seagrasses are being lost at the same rate as Amazonian rainforests, and little is being done to conserve these habitats as their importance isn't fully understood. But scientists at Swansea University have just published two studies in the journals Marine Pollution Bulletin and Marine Biodiversity showing these areas are vital to the wellbeing of juvenile fish, and consequently the fishing industry. >> Read the Full Article
Icequakes triggered by earthquakes
In 2010, a powerful magnitude-8.8 earthquake struck off the coast of central Chile, rocking much of the country and producing tremor as far away as Argentina and Peru. But a new study suggests its effects were felt even farther awayâ€”in Antarctica. In the wake of the Maule temblor, the scientists found, several seismic stations on the frozen continent registered "ice quakes," probably due to fracturing of the ice as the planet's crust shook. Earthquakes are already known to affect Antarcticaâ€™s ice shelves, thanks to the tsunamis they can spawn. Tsunami waves can propagate for great distances across the ocean; if the waves reach Antarcticaâ€™s ice shelves - the floating platforms of ice surrounding the continentâ€”they can push and pull on the ice, promoting fractures and ultimately helping large chunks of ice break off, or calve. >> Read the Full Article
