Wolf reintroduction proposed in Scottish Highland test case
Researchers are proposing in a new report that a major experiment be conducted to reintroduce wolves to a test site in the Scottish Highlands, to help control the populations and behavior of red deer that in the past 250 years have changed the whole nature of large ecosystems. view more (2009-07-21)
What led to the Nigerian boycott of the polio vaccination campaign?
Suspicion and mistrust of Western medicine led Muslim religious leaders in three northern states of Nigeria to call for the 2003 boycott of the national polio vaccine campaign, according to a historical analysis in PLoS Medicine. The boycott led to fresh outbreaks of polio in Nigeria. view more (2007-03-20)
Climate change could impact vital functions of microbes
Global climate change will not only impact plants and animals but will also affect bacteria, fungi and other microbial populations that perform a myriad of functions important to life on earth. view more (2008-06-03)
Higher carbon dioxide, lack of nitrogen limit plant growth
Earth's plant life will not be able to "store" excess carbon from rising atmospheric carbon dioxide levels as well as scientists once thought because plants likely cannot get enough nutrients, such as nitrogen, when there are higher levels of carbon dioxide view more (2006-04-13)
Fossil and molecular evidence reveals the history of major marine biodiversity hotspots
The journal "Science" has published in the issue of the 1st of August the results of a detailed research work about the evolution of marine diversity all through the last 50 million years. view more (2008-08-07)
Decline in Alaskan sea otters affects bald eagles' diet
Sea otters are known as a keystone species, filling such an important niche in ocean communities that without them, entire ecosystems can collapse. view more (2008-10-03)
Media invitation: How many species in Noah's Arc?
Scientists gather in Mallorca (Spain) to assess the role of biodiversity in ecosystem function. The remarkable increase, towards the end of 20th Century in the rate of species extinctions and the loss of biological diversities in the planet's ecosystems have generated considerable concern on the consequences that, beyond the severe damage of the... view more...

260 million-year-old reptiles from Russia possessed the first modern ears
The discovery of the first anatomically modern ear in a group of 260 million-year-old fossil reptiles significantly pushes back the date of the origin of an advanced sense of hearing, and suggests the first known adaptations to living in the dark. view more (2007-09-12)
Organic Soils Continue to Acidify Despite Reduction in Acidic Deposition
Following the Clean Air Act Amendments of 1970 and 1990 acidic deposition in North America has declined significantly since its peak in 1973. Consequently, research has shifted from studying the effects of acidic deposition to the recovery of these aquatic and terrestrial ecosystems. view more (2009-01-13)
Resilience concepts poised to aid management of coastal marine ecosystems
The January 2008 issue of BioScience includes a special section entitled "Managing for Resilience in Coastal Marine Ecosystems." The four articles in the section highlight different aspects of attempts to incorporate modern concepts from mathematical ecology into ecosystem-based management of coastal marine areas. view more (2008-01-02)
International team of scientists warns of climate change's impact on global river flow
A global analysis of the potential effect of climate change on river basins indicates that many rivers impacted by dams or extensive development will require significant management interventions to protect ecosystems and people, according to an article published today in the online version of Frontiers in Ecology and the Environment. view more (2007-10-15)
Cassini's new view of land of lakes and seas
The best views of the hydrocarbon lakes and seas on Saturn's moon Titan taken by the Cassini spacecraft are being released today. view more (2007-10-12)
Ancient amphibians evolved a bite before migrating to dry land
Ancient aquatic amphibians developed the ability to feed on land before completing the transition to terrestrial life, researchers from Harvard University report this week in the Proceedings of the National Academy of Sciences. view more (2007-04-17)
Fossils suggest earlier land-water transition of tetrapod
New evidence gleaned from CT scans of fossils locked inside rocks may flip the order in which two kinds of four-limbed animals with backbones were known to have moved from fish to landlubber. view more (2009-04-20)
University of Ulster to establish 'Green' Power Research Centre
The University of Ulster is set to become the "green" powerhouse of Ireland. It is to establish a state-of-the-art research centre on its Jordanstown campus to investigate new and renewable sources of energy. Work on the multi-million pound development is expected to begin later this year and is scheduled to be completed by the autumn of... view more... (2001-09-18)
Potentially harmful chemicals found in forest fire smoke
Researchers have detected common plant toxins that affect human health and ecosystems in smoke from forest fires. The results from the new study also suggest that smoldering fires may produce more toxins than wildfires - a reason to keep human exposures to a minimum during controlled burns. view more (2009-04-30)
Scientists find universal rules for food-web stability
The findings, published in this week's issue of Science, conclude that food-web stability is enhanced when many diverse predator-prey links connect high and intermediate trophic levels. view more (2009-08-07)
Forest fires may lead to cooling of northern climate
Countering hypotheses that forest fires in Alaska, Canada and Siberia warm the climate, scientists at UC Irvine have discovered that cooling may occur in areas where charred trees expose more snow, which reflects sunlight into space. view more (2006-11-17)
Scientists Verify Predictive Model for Winter Weather
Scientists have verified the accuracy of a model that uses October snow cover in Siberia to predict upcoming winter temperatures and snowfall for the high- and mid-latitudes of the Northern Hemisphere. view more (2007-08-21)
