WHAT FACTORS FAVOUR THE ECOLOGICAL DIVERSITY OBSERVED IN ATOLL LAGOONS ?
The first step in the investigation was the mapping by remote sensing techniques of more than two-thirds of the 76 atolls of the Tuamotu archipelago. High resolution maps, which did not exist before, were then established. Using the cartographic data thus gleaned alongside morphometric parameters picked out (size and shape of the lagoons, degree... view more... (1999-04-14)
Historical Increase in Corn Yield -- It's in the Roots
One of the most significant developments in agricultural growth in modern times has been the continuous and substantial increase in corn yield over the past 80 years in the U.S. Corn Belt. view more (2009-03-17)
DOE publishes research roadmap for developing cleaner fuels
The U.S. Department of Energy (DOE) today released an ambitious new research agenda for the development of cellulosic ethanol as an alternative to gasoline. view more (2006-07-07)
UC Riverside Researchers Create First Synthetic Cellulosome in Yeast
A team of researchers led by University of California, Riverside (UCR) Professor of Chemical Engineering Wilfred Chen has constructed for the first time a synthetic cellulosome in yeast, which is much more ethanol-tolerant than the bacteria in which these structures are normally found. view more (2009-10-30)
Plants grow bigger and more vigorously through changes in their internal clocks
Hybrid plants, like corn, grow bigger and better than their parents because many of their genes for photosynthesis and starch metabolism are more active during the day, report researchers from The University of Texas at Austin in a new study published in the journal Nature. view more (2008-11-24)
Breaking the Ties that Bind: New Hope for Biomass Fuels
Los Alamos National Laboratory researchers have discovered a potential chink in the armor of fibers that make the cell walls of certain inedible plant materials so tough. view more (2009-04-23)
U.N. Climate Change Conference considers ancient soil replenishment technique in battle against global warming
Former inhabitants of the Amazon Basin enriched their fields with charred organic materials-biochar-and transformed one of the earth's most infertile soils into one of the most productive. view more (2008-12-18)
Feeding and fueling the future: the bioenergy potential of reviving abandoned agricultural land
Across the globe, hundreds of millions of acres of once-productive agricultural land lie abandoned, according to a new report from researchers at Stanford University and the Carnegie Institution for Science. If this land was used to grow crops for conversion into biofuel, it could help ease the energy crunch without worsening the world food... view more... (2008-06-25)
Carolina 'Clean' Coal: NC State Researchers Work to Make Wood a New Energy Source
Is wood the new coal? Researchers at North Carolina State University think so, and they are part of a team working to turn woodchips into a substitute for coal by using a process called torrefaction that is greener, cleaner and more efficient than traditional coal burning. view more (2009-03-12)
Extreme environment biology research may help solve lignocellulosic ethanol puzzle
Buried beneath a sulfurous cauldron in European seas lies a class of microorganisms known as "extremophiles," so named because of the extreme environmental conditions in which they live and thrive. view more (2007-06-13)
Biofuels Can Replace a Third of Transportation Fuel Needs with Significant Research and Policy Effort
A group of experts in science, engineering and public policy from the Georgia Institute of Technology, Imperial College London and the Oak Ridge National Laboratory recommend a comprehensive research and policy plan aimed at increasing the practicality of using biofuels and biomaterials as a supplement to petroleum. view more (2006-02-01)
Scientific issues associated with carbon-neutral energy sources such as cellulosic ethanol
Professor Chris Somerville of the Carnegie Institution and Stanford University, explained advances in plant science research that are both needed and achievable to reduce costs and multiply current levels of production of biofuels from plant cellulose (biomass). view more (2006-08-07)
MU Researchers Make Discovery in Molecular Mechanics of Phototropism
In a paper published in the Journal of Biological Chemistry, scientists at the University of Missouri-Columbia reported molecular-level discoveries about the mechanisms of phototropism, the directional growth of plants toward or away from light. view more (2007-07-09)
Increased carbon dioxide in atmosphere linked to decreased soil organic matter
A recent study at the University of Illinois created a bit of a mystery for soil scientist Michelle Wander - increased carbon dioxide in the atmosphere was expected to increase plant growth, increase plant biomass and ultimately beef up the organic matter in the soil -- but it didn't. view more (2008-03-12)
Duckweed genome sequencing has global implications
Three plant biologists at Rutgers' Waksman Institute of Microbiology are obsessed with duckweed, a tiny aquatic plant with an unassuming name. Now they have convinced the federal government to focus its attention on duckweed's tremendous potential for cleaning up pollution, combating global warming and feeding the world. view more (2008-07-09)
Abandoned farmlands are key to sustainable bioenergy
Biofuels can be a sustainable part of the world's energy future, especially if bioenergy agriculture is developed on currently abandoned or degraded agricultural lands, report scientists from the Carnegie Institution and Stanford University. view more (2008-06-24)
Rot's unique wood degrading machinery to be harnessed for better biofuels production
An international team led by scientists from the U.S. Department of Energy (DOE) Joint Genome Institute (JGI) and the U.S. Department of Agriculture Forest Service, Forest Products Laboratory (FPL) have translated the genetic code that explains the complex biochemical machinery making brown-rot fungi uniquely destructive to wood. view more (2009-02-06)
Nitrogen research shows how some plants invade, take over others
Biologists know that when plants battle for space, often the actual battle is for getting the nitrogen. view more (2009-07-07)
Nutrient recycling - the ideal way to avoid nutrient limitation in a grazer community
The rocky shore of Lake Erken, Sweden, is inhabited by the sessile psychomyiid caddisfly Tinodes waeneri (L.). The larva lives in a gallery, consisting of a spun silken web plus other organic and inorganic material associated with the web (Danecker 1961, Becker 1993, Hasselrot 1993a). The additional organic material includes detritus and living... view more... (2000-01-17)
Level of important greenhouse gas has stopped growing
Scientists at UC Irvine have determined that levels of atmospheric methane - an influential greenhouse gas - have stayed nearly flat for the past seven years, which follows a rise that spanned at least two decades. view more (2006-11-21)
