Wildfire Climate Interactions Pose Long Term Problems
2013-05-22 10:46:39

redOrbit Staff & Wire Reports - Your Universe Online The US Forest Service voiced its concern on Tuesday over the atmospheric effects of wildfire emissions on climate change, saying the issue is of great importance to scientists and policymakers alike. The warnings are particularly important given recent projections of an average 50-percent increase in wildfires across the US — and over 100 percent in some areas of the West — by 2050, the Service said. The agency...

Satellites See Potential Wildfire Threats In SoCal
2013-05-14 08:26:11

April Flowers for redOrbit.com - Your Universe Online An ongoing project using NASA and Indian satellite data has identified two factors that are creating a potentially volatile Southern California wildfire season. Scientists from NASA´s Jet Propulsion Laboratory (JPL) and Chapman University have tracked the relationship between rainfall and the growth and drying-out of vegetation in recent months, during what has been an abnormally dry year. The data shows that the...

How Plants Benefit From Forest Fires
2013-04-30 11:18:53

Brett Smith for redOrbit.com - Your Universe Online Forest fires are a major cause of plant death and destruction, but they can also be a source of life as some dormant seeds begin to germinate in the aftermath of a raging inferno. Previous research has shown chemicals in the smoke of burning trees called karrikins“¯are responsible for this phoenix-like rebirth. Now, a new study in the Proceedings of the National Academy of Sciences has described new details on the mechanism...

Long-Term Plant-Monitoring Program Digitized By Arizona Researchers
2013-04-30 10:04:51

April Flowers for redOrbit.com - Your Universe Online More than a hundred years of growth data on individual plants has been digitized by a team of researchers at the University of Arizona´s Tumamoc Hill. The team has made this data available for study by people around the globe. New insights into the behavior of ecosystems can be developed by knowing how plants respond to changing conditions over many decades. Tumamoc Hill´s permanent research plots represent the...

Wildfires Can Burn Hot Without Ruining Soil
2013-04-24 08:52:48

American Geophysical Union When scientists torched an entire 22-acre watershed in Portugal in a recent experiment, their research yielded a counterintuitive result: Large, hot fires do not necessarily beget hot, scorched soil. It´s well known that wildfires can leave surface soil burned and barren, which increases the risk of erosion and hinders a landscape´s ability to recover. But the scientists´ fiery test found that the hotter the fire–and the denser the...

Airborne imaging technology developed at NASA and transferred to the U.S. Department of Agriculture's Forest Service (USFS) in 2012 is being tested to prepare for this year's wildfire season in the western United States. The Autonomous Modular Sensor (AMS) is a scanning spectrometer designed to help detect hot-spots, active fires, and smoldering and post-fire conditions. Scientists at NASA's Ames Research Center in Moffett Field, Calif., and USFS engineers installed it on a Cessna Citation...

Bats Undisturbed By Forest Fires
2013-03-08 09:07:56

Alan McStravick for redOrbit.com - Your Universe Online Forest fires are responsible for laying waste to entire ecosystems. As the flames rush through, animals attempt to make their escape, seeking shelter in less incendiary locales. Charred remains of trees and ground cover are completely unsuitable for sustaining the life of the animals that once called the area home. However, a new study led by bat ecologist Winifred Frick of the University of California, Santa Cruz (UCSC) reports the...


Word of the Day
endocarp
  • The hard inner (usually woody) layer of the pericarp of some fruits (as peaches or plums or cherries or olives) that contains the seed.
This word comes from the Greek 'endon,' in, within, plus the Greek 'kardia,' heart.
