Climate change and permafrost thaw alter greenhouse gas emissions in northern wetlands
Permafrost - the perpetually frozen foundation of North America - isn't so permanent anymore, and scientists are scrambling to understand the pros and cons when terra firma goes soft. view more (2007-08-10)
Ulster cannot afford to fall behind in science
SBS today expressed surprise and disappointment that the Northern Ireland Executive has not allocated any extra resources for university research in its draft budget. view more (2002-09-26)
Controversial new climate change results
New data show that the balance between the airborne and the absorbed fraction of carbon dioxide has stayed approximately constant since 1850, despite emissions of carbon dioxide having risen from about 2 billion tons a year in 1850 to 35 billion tons a year now. view more (2009-11-11)
Science Matters in Northern Ireland
SBS today welcomed the opening of the new Centre for Molecular Biosciences at the University of Ulster, but highlighted the general lack of government investment in science in Northern Ireland. In a talk to scientists in Northern Ireland, Dr Peter Cotgreave, Director of SBS, pointed out that overall government investment in the science base is... view more... (2002-02-01)
Yale study: Most polluted ecosystems recoverable
Most polluted or damaged ecosystems worldwide can recover within a lifetime if societies commit to their cleanup or restoration, according to an analysis of 240 independent studies by researchers at the Yale School of Forestry & Environmental Studies. view more (2009-05-28)
New Method Confirms Importance of Fungi in Arctic Nitrogen Cycle
A new method to calculate the transfer of nitrogen from Arctic mushrooms to plants is shedding light on how fungi living symbiotically on plant roots transfer vital nutrients to their hosts. view more (2006-05-10)
Fear of crime in Northern Ireland is not irrational
Fear of crime in Northern Ireland is a rational perception and not based just on irrational emotion. This contrasts with the view that fear of crime is a separate issue from the reality of being a victim of crime. The inadequacy of the method for investigating fear of crime has been responsible for misleading the public. view more (1999-03-26)
Sea Grant warns of dumping seafood
In its latest outreach campaign, MIT Sea Grant has developed an educational pamphlet to encourage people not to release or dump live and fresh seafood and seafood waste into the wild. view more (2006-06-22)
Grasslands won't help buffer climate change as carbon dioxide levels rise
Because grasslands and forests operate in complex feedback loops with both the atmosphere and soil, understanding how ecosystems respond to global changes in climate and element cycling is critical to predicting the range of global environmental changes-and attendant ecosystem responses-likely to occur. view more (2005-08-09)
Nature can help reduce greenhouse gas, but only to a point
Plants apparently do much less than previously thought to counteract global warming, according to a paper to be published in next week's online edition of Proceedings of the National Academy of Sciences. view more (2006-04-11)
In the warming West, climate most significant factor in fanning wildfires' flames
The recent increase in area burned by wildfires in the Western United States is a product not of higher temperatures or longer fire seasons alone, but a complex relationship between climate and fuels that varies among different ecosystems. view more (2009-06-26)
Joint U.S. - Norwegian Study Provides New Insights into Marine Ecosystems and Fisheries Production
NOAA and Norwegian researchers recently completed a comparative analysis of marine ecosystems in the North Atlantic and North Pacific to see what factors support fisheries production, leading to new insights that could improve fishery management plans and the ecosystems. view more (2009-10-01)
NAU researchers chirping over discovery of new cricket genus
A Northern Arizona University doctoral candidate and a National Park Service researcher have discovered a new genus of cave cricket. view more (2006-05-08)
Fish food fight: Fish don't eat trees after all, says new study
What constitutes fish food is a matter of debate. A high-profile study a few years ago suggested that fish get almost 50 percent of their carbon from trees and leaves, evidence for a very close link between the terrestrial and aquatic ecosystems. view more (2009-11-24)
Introduced marine species get larger in the invaded region
The transport of species outside their native region through human activities has often had a dramatic impact on the ecosystems into which these species are introduced and on the surrounding economies. The consequences of introduction for the introduced species itself, including changes in body size and shape, are less recognized. Prior studies of... view more... (2003-08-13)
Lichens function as indicators of nitrogen pollution in forests
Scientists have found lichens can give insight into nitrogen air pollution effects on Sierra Nevada and San Bernardino mountain ecosystems, and protecting them provides safeguards for less sensitive species. view more (2008-10-07)
"Acid rain" and forest mass: another perspective
A few years ago the study of the effects of atmospheric deposition on forest ecosystems reached beyond the scientific sphere and the term "acid rain" was coined. view more (2005-10-14)
Rivers indicate earlier snowmelt in eastern North America
Scientists at the U.S. Geological Survey (USGS) have found evidence in eastern North America that the snow is melting and running off into rivers earlier than it did in the first half of the 20th century. view more (2006-03-27)
NOAA report states half of US coral reefs in 'poor' or 'fair' condition
Nearly half of U.S. coral reef ecosystems are considered to be in "poor" or "fair" condition according to a new NOAA analysis of the health of coral reefs under U.S. jurisdiction. view more (2008-07-08)
CSIRO imagery shows outer Great Barrier Reef at risk from river plumes
A stunning series of satellite imagery of Australia's Great Barrier Reef released by the CSIRO shows for the first time visual confirmation of the theory that sediment plumes travel to the outer reef, and beyond. view more (2007-02-28)
