New perspective on agricultural plastic, debris burning, and air quality

Posted by External 3 days ago General
http://feeds.sciencedaily.com — To reduce fire hazard, wildland managers often utilize the silvicultural practice of mechanically cutting woody shrubs and suppressed trees. These cuttings and other post-logging debris are then burned during periods of low fire danger in order to dispose of the material. Managers often cover all or part of the debris pile with low-density polyethylene plastic, commonly referred to as agricultura Read More

Storm-triggered landslides: Examining causes of devastating debris flow

Posted by External 8 days ago General
http://feeds.sciencedaily.com — Storm-triggered landslides cause loss of life, property damage, and landscape alterations. For instance, the remnants of Hurricane Camille in 1969 caused 109 deaths in central Virginia, after 600 mm of rain fell in mountainous terrain in 6 hours. More recently, on 8 August 2010, a rainstorm-induced landslide devastated the Chinese county of Zhouqu, causing more than 1000 deaths. A new modeling st Read More

Catastrophic debris avalanches: A second volcanic hazard

Posted by External 10 days ago General
http://feeds.sciencedaily.com — Volcanic hazards aren't limited to eruptions. Debris avalanche landslides can also cause a great deal of damage and loss of life. Stratovolcanoes, with their steep, conical shapes made up of lava and unconsolidated mixed materials, can reach a critical point of instability when they overgrow their flanks. This leads to partial collapse, and the product of this slope failure is a large-scale, rapi Read More

All the world's oceans have plastic debris on their surface

Posted by External 28 days ago General
http://feeds.sciencedaily.com — The Malaspina Expedition, led by the Spanish National Research Council, has demonstrated that there are five large accumulations of plastic debris in the open ocean that match with the five major twists of oceanic surface water circulation. In addition to the known accumulation of plastic waste in the North Pacific, there are similar accumulations in the central North Atlantic, the South Pacific, Read More

Forest loss starves fish: Forest debris that drains into lakes is important to freshwater food chains

Posted by External 46 days ago General
http://feeds.sciencedaily.com — Research shows forest debris that drains into lakes is an important contributor to freshwater food chains – bolstering fish diets to the extent that increased forest cover causes fish to get ‘fat’ and sparse forest leaves smaller, underfed fish. Read More

How forest debris affects freshwater food chains

Posted by External 48 days ago General
http://www.enn.com — While one may think that forest and lake ecosystems are two separate networks, new research shows how forest debris is an important contributor to freshwater food chains. How? Debris in the form of organic carbon from trees washes into freshwater lakes, which consequently supplements the diets of microscopic zooplankton and the fish that feed on them. Read More
