Nutrients cause increase in parasites and frog deformities
Extra and missing-legged frogs have become increasingly common in North American wetlands over the last decade. Research implicates a flatworm parasite, Ribeiroia ondatrae, as the culprit of these deformities. Reasons for the apparent increase in infection and malformations, however, have remained a mystery. In the July issue of Ecology Letters,... view more... (2004-06-10)
Using plants and microbes to purify polluted industrial wastewater
Wetlands are nature's water filters. They collect water around river mouths and marshes, and whole communities of plants and micro-organisms feed off detritus in these murky depths. Conventional chemical treatments of industrial waters consume cash, energy and time. Wetlands, by contrast, grow and clean themselves while they act as... view more... (2003-10-07)
Explaining the methane mystery
Scientists have explained why atmospheric levels of the greenhouse gas methane have stabilised in recent years, but warn that increases could resume in the near future. view more (2006-09-28)
Smithsonian researchers develop models to assess wetland health
Healthy wetlands perform vital ecological functions in a watershed. But assessing their condition and ability to perform those functions is not easy, especially as wetlands are disappearing fast due to human encroachment. view more (2007-09-17)
Beavers can help ease drought
They may be considered pests, but beaver can help mitigate the effects of drought, and because of that, their removal from wetlands to accommodate industrial, urban and agricultural demands should be avoided, according to a new University of Alberta study. view more (2008-02-21)
LSU and Ohio State Battle on Football Field, Collaborate in Research Field
LSU and Ohio State University will battle for the BCS National College Football Championship in the Superdome early next week, but if the game was held in the Louisiana wetlands instead, the entire field would disappear before halftime. view more (2008-01-07)
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)
The South East Asian snail disaster
A promising enterprise became an economical and ecological disaster. The golden apple snail (Pomacea canaliculata) that was brought to Asia in 1980 to be cultured in ponds for human consumption instead spread through rice fields, irrigation channels and wetlands. It had a voracious appetite for rice seedlings and soon became a dreaded pest in the... view more... (2004-03-31)
Watersports are a breeding nuisance
More than one-third of the UK’s wetlands is suffering high levels of disturbance, according to a new study by the Wildfowl & Wetlands Trust (WWT). Speaking at the British Ecological Society’s Winter Meeting, to be held at the University of Warwick on 18–20 December 2001, Dr James Robinson of the WWT will warn that the impact... view more...

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)
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)
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)
Herons persist in Chicago wetlands despite exposure to banned chemicals
Herons nesting in the wetlands of southeast Chicago are still being exposed to chemicals banned in the U.S. in the 1970s, a research team reports. The chemicals do not appear to be affecting the birds' reproductive success, however. view more (2008-01-17)
Frozen methane chunks not responsible for abrupt increases in atmospheric methane
Icy chunks of frozen methane and water are not responsible for the periodic increases in atmospheric methane recorded in Greenland ice cores. view more (2006-02-10)
Hot volcanic eruptions could lead to a cooler Earth
Volcanic eruptions may be an agent of rapid and long-term climate change, according to new research by British scientists. view more (2005-06-13)
Liverpool scientists work to improve water quality in Ghana
Ghana's large and growing population relies on wetlands for food and water and so experts at the University's Institute for Sustainable Water, Integrated Management and Ecosystem Research (SWIMMER) have launched a research and training project near Accra, in Southern Ghana, to prevent continued environmental decline through pollution and over-use... view more...

Study rules out ancient 'bursts' of methane from seafloor deposits
A dramatic increase about 12,000 years ago in levels of atmospheric methane, a potent greenhouse gas, was most likely caused by higher emissions from tropical wetlands or from plant production, rather than a release from seafloor methane deposits. view more (2006-08-25)
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)
Burning wetlands unleash sequestered mercury in wake of climate change
Climate change appears to be contributing to the waking of a dangerous sleeping giant in the most northern wetlands of North America - mercury. view more (2006-08-22)
New cost-benefit model will aid efforts to conserve wilderness: UBC researcher
A new conservation model that measures the value of ecosystem services benefiting humans - ranging from flood control to crop pollination - can foster more win-win solutions between wilderness advocates and landowners. view more (2006-10-31)
