Wetlands likely source of methane from ancient warming event
An expansion of wetlands and not a large-scale melting of frozen methane deposits is the likely cause of a spike in atmospheric methane gas that took place some 11,600 years ago, according to an international research team led by Scripps Institution of Oceanography at UC San Diego. view more (2009-04-24)

Shifts in soil bacterial populations linked to wetland restoration success
A new study led by Duke University researchers finds that restoring degraded wetlands -- especially those that had been converted into farm fields -- actually decreases their soil bacterial diversity. view more (2008-11-13)
Stanford researchers: Global warming is killing frogs and salamanders in Yellowstone Park

New CU-Boulder study shows diversity decreases chances of parasitic disease
A new University of Colorado at Boulder study showing that American toads who pal around with gray tree frogs reduce their chances of parasitic infections known to cause limb malformations has strong implications for the benefits of biodiversity on emerging wildlife diseases. view more (2008-10-22)
Beavers: Dam good for songbirds
The songbird has a friend in the beaver. According to a study by the Wildlife Conservation Society (WCS), the busy beaver's signature dams provide critical habitat for a variety of migratory songbirds, particularly in the semi-arid interior of the West. view more (2008-10-09)
Bays on US Gulf Coast vulnerable to flooding
The most comprehensive geological review ever undertaken of the upper U.S. Gulf Coast suggests that a combination of rising seas and dammed rivers could flood large swaths of wetlands this century in one or more bays from Alabama to Texas. view more (2008-10-03)
Commercial aquatic plants offer cost-effective method for treating wastewater
Nursery and greenhouse operations depend on the use of fertilizers, growth regulators, insecticides, and fungicides. Growers also rely on the use of soilless media, or substrate, in the production of container crops. view more (2008-09-30)
Wetlands Restoration Not a Panacea for Louisiana Coast
Counting on wetlands restoration projects to protect storm buffeted infrastructure along the Louisiana Coast is likely to be a "losing battle" that provides "false hope" and prevents endangered communities from clearly planning for their future, says a researcher from Western Carolina University (WCU). view more (2008-09-29)
Evaluating ecosystem services
Environmental conservation efforts have traditionally focused on protecting individual species or natural resources. Scientists are discovering, however, that preserving the benefits that whole ecosystems provide to people is more economically and environmentally valuable. At the Annual Meeting of the Ecological Society of America (ESA),... view more... (2008-08-05)
Rising energy, food prices major threats to wetlands as farmers eye new areas for crops
Critical food shortages and growing demand for bio-fuels and hydro-electricity due to high fossil fuel prices rank among the greatest threats today to the preservation of precious wetlands worldwide as farmers and developers look for new areas for agriculture, energy crop plantations and hydro dams. view more (2008-07-28)
New population of highly threatened greater bamboo lemur found in Madagascar
Researchers in Madagascar have confirmed the existence of a population of greater bamboo lemurs more than 400 kilometers (240 miles) from the only other place where the Critically Endangered species is known to live, raising hopes for its survival. view more (2008-07-22)
Massive greenhouse gases may be released as destruction, drying of world wetlands worsens: UN
Leading world scientists convene in Brazil July 21-25 amid growing concern that evaporation and ongoing destruction of world wetlands, which hold a volume of carbon similar to that in the atmosphere today, could cause them to exhale billows of greenhouse gases. view more (2008-07-21)
Plan to conserve forests may be detrimental to other ecosystems
Conserving biodiversity must be considered when developing plans to reduce greenhouse gas emissions from deforestation, researchers warn in today's edition of Science. view more (2008-06-13)
Woody and aquatic plants pose greatest invasive threat to China
Although China currently has fewer invasive woody plants than the United States, China's potential for invasion by nonnative trees and shrubs is high, according to an article in the May 2008 issue of BioScience. view more (2008-05-01)
