Scientists have developed a new way to rescue the Bogong High Plains and their endangered alpine wetlands from invading European willows. The new strategy calls for an exclusive focus on eradicating willows within the threatened bogs — patches of muddy ground where the soil is always wet, says Dr Joslin Moore from the National Environmental Research Program´s (NERP) Environmental Decisions Hub and the Royal Botanic Gardens Melbourne. “After a severe bushfire burned out...

New Research On Seaweeds Shows It Takes More Than Being Flexible To Survive Crashing Waves
2012-05-10 12:58:48

Bladed and branched algae adapted to strong wave conditions are able to reconfigure their shape and size Seaweeds are important foundational species that are vital both as food and habitat to many aquatic and terrestrial shore organisms. Yet seaweeds that cling to rocky shores are continually at risk of being broken or dislodged from their holds by crashing waves with large hydrodynamic forces. So how do such seaweeds survive in intertidal zones? Do they have special properties that make...

Seventy-five per cent of the world's heather moorlands are in the UK. However, pollution, overgrazing and wild fires have damaged large areas. Several organizations in the Peak District National Park are trying to restore and conserve the moorland habitat. As part of the Festival of Social Science organized by the Economic and Social Research Council (12-21 March 2010), the Peak District National Park Authority in Partnership with the National Trust and Moors for the Future is running a walk...

The Spanish government is hoping to save a dried wetland from an underground peat fire by unleashing floodwaters onto an expanse of the marsh now under threat due to past water mismanagement, The Associated Press reported. UNESCO recognizes the wetlands of Las Tablas de Daimiel National Park as environmentally valuable because of their importance to both resident and migrating birds. Waters were diverted over some 93 miles from the Tagus River and began pouring from an underground pipe onto...

Physicists from Canada, France and Britain studying so-called washboard road ripples say their findings might eliminate bumpy vehicle rides. The researchers said they discovered ripples appear even when the springy suspension of a car and the rolling shape of a wheel are eliminated. To understand the washboard road effect, we tried to find the simplest instance of it, University of Toronto physicist, Stephen Morris, a member of the research team, said. "We built lab experiments in which we...

Just about any road with a loose surface "” sand or gravel or snow "” develops ripples that make driving a very shaky experience. A team of physicists from Canada, France and the United Kingdom have recreated this "washboard" phenomenon in the lab with surprising results: ripples appear even when the springy suspension of the car and the rolling shape of the wheel are eliminated. The discovery may smooth the way to designing improved suspension systems that eliminate the bumpy...

By BEKAH PORTER GALENA, Ill. - The construction site for the large-scale dairy near Nora is not in a karst area.Two defense witnesses delivered this message Monday as hearings resumed in the preliminary injunction case that could halt construction on the estimated 5,500- cow operation being built by California businessman A.J. Bos.The defense's testimony contrasted the opinions of several witnesses for the plaintiffs in the case. About 20 individuals and the nonprofit organization, Helping...

China finds 14,000-km underground rivers in rock desert areas BEIJING, Sept. 29 (Xinhua) -- A newly conducted geological survey has found more than 3,000 underground rivers with a total length of 14,000 kilometers in southwest China's rock desert areas. A latest report released by the China Geological Survey showed that these underground rivers collect water from a combined area of 300,000 square kilometers, with an annual runoff of 47 billion cubic meters, equivalent to that of the Yellow...

Scientists have found that the ground is drying out in a 13,700-year-old peat bog, just another sign, they say, of the Earth's warming climate. Ecologist Ed Berg says the peat bog is turning into forest. "There has been a big change," Berg said. Core samples taken from the bog show moss nearly 22 feet under the ground, with no sign of trees or shrubs growing here for centuries, Berg said. The bog could be covered by black spruce trees during the next 50 years, he said. Alaska is one state,...

By Wade Rawlins, The News & Observer, Raleigh, N.C. Jun. 21--The fire in Pocosin Lakes National Wildlife Refuge in Eastern North Carolina has burned more intensely and spread more widely because of changes to the land in earlier decades to promote farming. Much of the swampy land blackened by the Evans Road fire is crosshatched with ditches and canals that lower the water level and make the ground suitable for growing crops. The drainage ditches also allow the carbon-rich peat soil...

Mudflats
2013-04-19 21:07:34

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...

Sky Islands
2009-07-04 14:40:55

Sky Islands are mountains located within ranges that are isolated by valleys in which other ecosystems are located. As a result, mountain ecosystems are isolated from each other, and species can develop separately, as occurs on island groups such as the Galápagos Islands. The best known example of sky islands are the northern end of the Sierra Madre Occidental in New Mexico, Arizona, Chihuahua and Sonora on the U.S.-Mexico border. Other sky islands of note in the U.S. are the Great...
