(Press-News.org) University of Oklahoma researchers are part of a growing cross-disciplinary collaboration that seeks to tap the potential of radar technologies to advance aeroecology—a field that integrates atmospheric science, earth science, geography, ecology, computer science, computational biology and engineering.
According to Phillip Chilson, professor in the OU School of Meteorology and Atmospheric Radar Research Center, radar technologies have the potential for detecting and monitoring organisms in the aerosphere, which requires a greater understanding of biology within the radar community and a familiarity of radar products among ecologists.
"Recent advances in radar hardware and signal processing methodologies coupled with innovations in computer and networking technologies have presented us with many opportunities for biological studies that were not available in the past five years," notes Chilson.
Jeffrey Kelly, professor in the OU Department of Zoology and Oklahoma Biological Survey, studies animal migration and is particularly interested in using radar data as a measure of the phenology of animal movements and aggregations, such as those of the purple martins.
"We have known for a long time that radio waves scattered from flying organisms (bioscatter) are detected by weather radars, but we have yet to harness the capacity of weather detection radars for biological research," says Chilson.
Kenneth Howard, NOAA scientist in the National Severe Storms Laboratory, has played an integral role in this collaboration by creating a suite of visualization and analytical tools for understanding biological patterns of bioscatter across the continental United States.
"Investigating behavior and ecology of airborne organisms in the aerosphere presents significant challenges and requires collaboration across multiple scientific disciplines to utilize technological advances for increasing ecological understanding," states Winifred F. Frick, a researcher at the University of California in Santa Cruz and organizer of the AAAS aeroecology symposium.
Ecologists must discover the best methods for detecting the presence, taxonomic identity, diversity and activity of organisms that use this aerial environment; identify ways to integrate relevant environmental variables at different temporal and spatial scales; and determine how best to understand and interpret behavioral, ecological and evolutionary responses of organisms in the context of complex meteorological conditions and patterns within natural and anthropogenically-altered environments.
"Appropriate integration of diverse tools and concepts for probing into the lives of organisms aloft are necessary for informed ecological and evolutionary concepts and management decisions associated with the spread of invasive species, emergence of infectious diseases, altered biodiversity, and the sustainability of terrestrial, aquatic and atmospheric environments," said Thomas H. Kunz, professor of biology and director of the Center of Ecology and Conservation Biology at Boston University and the opening symposium speaker.

For Northwestern University's Karen Smilowitz, the term "industrial engineering" is a bit of a misnomer. It evokes the image of the engineer in a factory with a stopwatch in hand, making sure production is as efficient as possible.
Surely some industrial engineers still do that. But these days, industrial engineering has grown beyond the factory and into the world of business. Others have taken it one step further -- into nonprofits.
Smilowitz has co-organized a symposium, "Doing Good with Good OR: Applying Operations Research for Societal Impact," to highlight such ...
Biodiversity loss is a growing concern. Protected areas are a instrument to counteract this trend. The UN's Convention on Biological Diversity conference of the parties in Nagoya (October 2010) set stringent new targets to be reached by 2020. At least 17% of terrestrial and inland water and 10% of coastal and marine areas have to be protected. But are protected areas really protected? Are they in the right place? Where should new protected areas be located? The European Commission's Joint Research Centre (JRC), in collaboration with other partners, is helping decision-makers ...
Nanotechnology offers a range of benefits over traditional materials and enables the development of innovative applications and products. However, there are often concerns about the safety aspects and to what extent these have been investigated. High-quality measurements are the basis for reliable safety assessments, process improvement, quality control and the development of new nanotechnology applications.
Until now, however, no certified benchmarks incorporating industrial nanoparticles were available. Some synthetic materials were available, but they were not fully ...
PROVIDENCE, R.I. [Brown University] — Last July, President Obama adopted the recommendations of a White House task force charged with devising a policy to better manage the nation's oceans, coastlines and the Great Lakes. The National Ocean Council is now charged with developing a plan to put the ideas into practice. Two scientists at Brown University will speak about the ecological and social facets of marine management this month at the annual meeting of the American Association for the Advancement of Science in Washington, D.C.

Once regarded as the stuff of science fiction, antimatter—the mirror image of the ordinary matter in our observable universe—is now the focus of laboratory studies around the world.
While physicists routinely produce antimatter with radioisotopes and particle colliders, cooling these antiparticles and containing them for any length of time is another story. Once antimatter comes into contact with ordinary matter it "annihilates"—or disappears in a flash of gamma radiation.
Clifford Surko, a professor of physics at UC San Diego who is constructing what he hopes will ...
WASHINGTON, D.C. -- Understanding and managing how humans and nature sustainably coexist is now so sweeping and lightning fast that it's spawned a concept to be unveiled at a major scientific conference today.
Meet "telecoupling."
Joining its popular cousins telecommuting and television, telecoupling is the way Jack Liu, director of the Human-Nature Lab/Center for Systems Integration and Sustainability at Michigan State University, is describing how distance is shrinking and connections are strengthening between nature and humans.
The "Telecoupling of Human and Natural ...
Once likened to a confusing tower of Babel, speaking more than one language can actually bolster brain function by serving as a mental gymnasium, according to researchers.
Recent research indicates that bilingual speakers can outperform monolinguals--people who speak only one language--in certain mental abilities, such as editing out irrelevant information and focusing on important information, said Judith Kroll, Distinguished Professor of Psychology, Penn State. These skills make bilinguals better at prioritizing tasks and working on multiple projects at one time.

BOSTON—A team of research biologists headed by Thomas H. Kunz, professor of biology and director of the Center of Ecology and Conservation Biology at Boston University, will conduct a symposium on the emerging scientific discipline of aeroecology at this year's American Association for the Advancement of Science (AAAS) annual meeting. Aeroecology is a new discipline whose unifying concept is a focus on the aerosphere and the myriad organisms that inhabit and depend on this aerial environment for their existence. The symposium is scheduled from 3:00-4:30 PM, Saturday, February ...
A shift in the global research landscape will reposition the United States as a major partner, but not the dominant leader, in science and technology research in the coming decade, according to a Penn State researcher. However, the U.S. could benefit from this research shift if it adopts a policy of knowledge sharing with the growing global community of researchers.
"What is emerging is a global science system in which the U.S. will be one player among many," said Caroline Wagner, associate professor of international affairs, who presented her findings today (Feb. 18) ...
