Researchers Find Uranium In A Natural Wetland More Mobile Than Previously Assumed

Ecole Polytechnique Fédérale de Lausanne Because they are known to mop up pollutants, artificial wetlands are considered to be an efficient strategy to contain waterborne uranium. But studying a natural wetland near a former uranium-mining site in the French region of Limousin, researchers have found that under certain circumstances, uranium can be partly remobilized into the surrounding water. In a recent publication in Nature Communications, they show how it becomes mobile again by...

Using Satellite Data To Monitor Wetlands
2013-07-23 13:36:55

ESA The use of satellite data to monitor wetlands for sustainable water management is growing. Following promising results from monitoring efforts in the Mediterranean, ESA is working with African partners to expand its GlobWetland project even further. In the heart of Jordan's eastern desert, an oasis of marshland and natural water collection makes up the Azraq wetland. The wetland and adjacent mudflat were recognized in 1977 as an important station for migratory birds by the Ramsar...

Foundational Concept Of Ecology Tested With Experiment

Acting through links between four trophic levels and across two ecosystems, purple loosestrife altered life in nearby ponds An elementary school science activity asks children who have each been assigned a wetland plant or animal to connect themselves with string and tape to other “organisms” their assigned plant or animal interacts with in some way. Once an ecosystem web has been created, the teacher describes an event that affects one “organism.” That...

Fifteen years of studying two experimental wetlands has convinced Bill Mitsch that turning the reins over to Mother Nature makes the most sense when it comes to this area of ecological restoration. Mitsch, an environment and natural resources professor at Ohio State University, has led the effort to compare the behavior of two experimental marshes on campus — one that was planted in 1994 with wetland vegetation and another that was left to colonize plant and animal life on its own....

Study shows plant assemblage, carbon resources depleted even after 100 years Wetland restoration is a billion-dollar-a-year industry in the United States that aims to create ecosystems similar to those that disappeared over the past century. But a new analysis of restoration projects shows that restored wetlands seldom reach the quality of a natural wetland. "Once you degrade a wetland, it doesn't recover its normal assemblage of plants or its rich stores of organic soil carbon, which...

Perennials, wetland plants compared for ability to remove harmful nitrogen, phosphorous Rapid population growth and urbanization have raised concerns over stormwater runoff contamination. Studies on watersheds indicate that excess nutrients, specifically nitrate"“nitrogen and soluble reactive phosphorus are found in stormwater runoff in many new urban areas. These pollutants degrade water quality and have an impact on the downstream ecosystem by contributing to the growth and...
