Perennial vegetation, an indicator of desertification in Spain
A team of scientists has analyzed 29 esparto fields from Guadalajara to Murcia and has concluded that perennial vegetation cover is an efficient early warning system against desertification in these ecosystems. The study has been published in the Ecology magazine. view more (2009-09-04)
Expert to Discuss Phosphorus' Impact on Gulf 'Dead Zone'
Phosphorus is an essential element in production agriculture, however fertilizer runoff and wastewater discharge have led to massive eutrophication problems in water bodies worldwide. view more (2009-10-29)
Ecologists use oceanographic data to predict future climate change
Ecologists and oceanographers are attempting to predict the future impacts of climate change by reconstructing the past behavior of Arctic climate and ocean circulation. view more (2008-11-07)
Ancient British bog provides clue to global warming
Analysis of sediments from a British bog suggest that methane emissions increased due to intense global warming around 55 million years ago. view more (2007-09-20)
Soil fertility in the tropics can be influenced by landscape and precipitation, study finds
A new study conducted in the Hawaiian Islands has revealed that landscape and erosion play crucial roles in determining soil fertility in tropical ecosystems. view more (2005-07-20)
Ecological globalization
Ecosystems are constantly exchanging materials through the movement of air in the atmosphere, the flow of water in rivers and the migration of animals across the landscape. view more (2008-06-02)
Tropical plants go with the flow ... of nitrogen
Tropical plants are able to adapt to environmental change by extracting nitrogen from a variety of sources, according to a new study that appears in the May 7 early online edition of The Proceedings of the National Academy of Sciences. view more (2007-05-08)
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)
Tropical forests — Earth's air conditioner
Planting and protecting trees—which trap and absorb carbon dioxide as they grow—can help to remove carbon dioxide from the atmosphere. view more (2007-04-10)
Humans
Mounting evidence that human activity is changing the world's oceans in profound and damaging ways is outlined in a new scientific discussion paper released today. view more (2009-07-29)
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)
Northwest Atlantic Ocean ecosystems experiencing large climate-related changes
Ecosystems along the continental shelf waters of the Northwest Atlantic Ocean—from the Labrador Sea south of Greenland all the way to North Carolina—are experiencing large, rapid changes, report oceanographers funded by the National Science Foundation (NSF) in the Feb. 23, 2007, issue of the journal Science. view more (2007-02-26)
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)
Dissolved organic matter in the water column may influence coral health
Bacterial communities endemic to healthy corals could change depending on the amount and type of natural and man-made dissolved organic matter in seawater, report researchers from The University of Texas at Austin Marine Science Institute and Mote Marine Laboratory in Sarasota, Florida. view more (2008-03-05)
Scientists find grass yield, carbon storage not affected by creepy-crawlies in the soil
New results from experiments at a unique ecology facility show that plant communities are dramatically altered by changes to the type of animal species living among their roots, but that key ecosystem measurements such as overall agricultural yield or the amount of soil carbon stored are unaffected. According to the results of a three year study... view more... (2002-10-18)
Beetles get by with a little help from their friends
Humans living in communities often rely on friends to help get what they need and, according to researchers in the lab of Cameron Currie at the University of Wisconsin-Madison, many microbes, plants and animals benefit from 'friendly' associations too. view more (2008-10-03)
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)
Evolution of skull and mandible shape in cats
In a new study published in the online-open access journal PLoS ONE, Per Christiansen at the Zoological Museum in Copenhagen, Denmark, reports the finding that the evolution of skull and mandible shape in sabercats and modern cats were governed by different selective forces, and the two groups evolved very different adaptations to killing. view more (2008-07-30)
Erie County home to plant never before recorded in Pa.
Western Pennsylvania Conservancy (WPC) scientists have discovered a plant in Erie County that has never been recorded in Pennsylvania. view more (2009-09-28)
Diversity of plant-eating fishes may be key to recovery of coral reefs
For endangered coral reefs, not all plant-eating fish are created equal. A report scheduled to be published this week in the early edition of the journal Proceedings of the National Academy of Sciences suggests that maintaining the proper balance of herbivorous fishes may be critical to restoring coral reefs, which are declining dramatically... view more...
