Latest Wetlands Stories
The Great Lakeâ€™s ice cover has gradually reduced by 30 percent since the 1970s, causing the biggest source of freshwater to become vulnerable to evaporation and poor water levels, say the scientists at the National Oceanic and Atmospheric Administration.
Rising atmospheric carbon dioxide is largely responsible for recent global warming and the rise in sea levels. However, a team of scientists, including two Smithsonian ecologists, have found that this same increase in CO2 may ironically counterbalance some of its negative effects on one of the planet's most valuable ecosystemsâ€”wetlands.
The water level in the Great Lakes has varied by only about two meters during the last century, helping them to play a vital role in the region's shipping, fishing, recreation and power generation industries.
Unparalleled warming over the last few decades has triggered widespread ecosystem changes in many temperate North American and Western European lakes, say researchers at Queen's University and the Ontario Ministry of the Environment.The team reports that striking changes are now occurring in many temperate lakes similar to those previously observed in the rapidly warming Arctic, although typically many decades later. The Arctic has long been considered a "bellwether" of what will eventually...
New research by Ducks Unlimited Canada (DUC) has identified that the continued loss of wetlands in Manitoba is increasing phosphorus loads into Lake Winnipeg equivalent to dumping 10 semi loads of commercial agricultural fertilizer or 544,000 bags of lawn fertilizer directly into the lake every year.
A study led by Japanese and German researchers suggests climate change will have different effects on lakes in warmer and colder regions of the Earth.
By Mike Taugher Staff Writer HAYWARD -- A backhoe clawed through a dirt berm Wednesday, creating a channel that Bay water poured through to former industrial salt ponds that had not tasted tidal waters for more than a century.
By E.B. FURGURSON III Staff Writer What is that big hole in the ground off Governor Bridge Road? Concerned residents are wondering what that huge pile of dirt and corresponding hole is all about.
By Akhilesh Sourav Jha JAIPUR: Wetlands are being developed in the vicinity of Jal Mahal (Mansagar Lake) to facilitate rejuvenation with clean water in this 250-year-old lake.
By Lisa Vernon-Sparks; David E Chopy COVENTRY -- Developer Nicholas E. Cambio has signed an agreement with the state to prevent the erosion of soil from his Centre of New England business park into neighboring lakes and wetlands. Under the agreement signed Sept.
Mudflats, or otherwise known as tidal flats, are coastal wetlands that form when mud is left behind by tides or rivers. They’re found in sheltered regions such as bayous, lagoons, estuaries, and bays. Mudflats might be seen geologically as exposed layers of bay mud, a result from the deposition of estuarine silts, marine animal detritus, and clays. The majority of the sediment in a mudflat is within the intertidal zone, therefore the flat is submerged and exposed about twice per day. In...
A wetland is an area of land that is saturated with water, either permanently or seasonally, such that it takes on the traits of a distinct ecosystem. First and foremost, the factor that distinguishes the wetlands from other land forms or water bodies is the unique vegetation that has adapted to its characteristic soil conditions. The wetland consists mostly of hydric soil, which is supportive of aquatic plants. The water that is found in wetlands can be saltwater, brackish, or freshwater....
