April Flowers for redOrbit.com - Your Universe Online If someone said “climate refuge” to you, what would come to mind? More than likely, the image of someone from a small tropical island in the Pacific, or of a low-lying delta like in Bangladesh – places where residents have been forced out of their homes by sea-level rise. The strict definition of a refugee in international law, according to a report by The Guardian, is rather narrow and typically includes only people displaced...
Mergent Inc. selects Black Mountain Systems as partner for municipal security master data integration. San Diego, CA (PRWEB) May 14, 2013 At the National Federation of Municipal Analysts (NFMA) Conference this week in San Diego, Black Mountain Systems announced its partnership with Mergent, Inc. as a new data provider to the Everest platform for municipal security master integration. Everest, Black Mountain’s industry-leading enterprise platform, allows users to efficiently access...
Brett Smith for redOrbit.com – Your Universe Online In a study that could have implications for ocean conservation and marine-based economic activity, researchers from the École Polytechnique Fédérale de Lausanne (EPFL) in Switzerland have found new details surrounding the symbiotic relationship between corals and algae. "Coral reefs are the jungles of our oceans - hotspots of biodiversity that easily outcompete all other marine ecosystems," said the EPFL’s Christophe Kopp,...
Lee Rannals for redOrbit.com – Your Universe Online University of Bristol researchers writing in the journal Geophysical Research Letters say limiting global warming would be key to buying the coral reefs some more time. The researchers found restricting greenhouse warming to just 50-100 parts per million (ppm) carbon dioxide, or approximately half the increase since the Industrial Revolution, would avoid large-scale reductions in reef habitat occurring in the future. "If sea...
April Flowers for redOrbit.com - Your Universe Online In the South Pacific, three types of coral reef island formations have fascinated geologists for ages. The coral of Tahiti forms a “fringing” reef, with a shelf growing close to the island’s shore. In Bora Bora, the “barrier” reefs are separated from the main island by a calm lagoon. Manuae represents the last type, an “atoll,” which appears as a ring of coral enclosing a lagoon with no island at the center. The...
Fragmentation remains due to highly specialized providers’ continued success. Dallas, TX (PRWEB) May 13, 2013 Merger and acquisition (M&A) activity in the recruitment process outsourcing space is at odds with the ongoing success of smaller, niche players, according to a new research study by Everest Group, an advisory and research firm on global services. Recent mergers — including Aon and Hewitt, Allegis Group and Talent2, Randstad and SFN Group, ADP and The RightThing, and most...
April Flowers for redOrbit.com - Your Universe Online Although scientists agree that coral reefs are in decline, a new study demonstrates that the collapse of such reefs can still be avoided with a combination of local and global action. "People benefit by reefs' having a complex structure – a little like a Manhattan skyline, but underwater," said Peter Mumby of The University of Queensland. "Structurally complex reefs provide nooks and crannies for thousands of species and provide...
April Flowers for redOrbit.com - Your Universe Online An international team of scientists, led by Julie Brigham-Grette of the University of Amherst, has analyzed the longest continental sediment core ever collected in the Arctic to provide “absolutely new knowledge” of Arctic climate from 2.2 million to 3.6 million years ago. "While existing geologic records from the Arctic contain important hints about this time period, what we are presenting is the most continuous archive of...
Lee Rannals for redOrbit.com – Your Universe Online One researcher from University of Southampton has carried out the most detailed analysis ever of the remains of an ancient medieval city dubbed "Britain's Atlantis." Professor David Sear of Southampton's Geography and Environment has created the most accurate map to date of the lost medieval town of Dunwich. His map includes the town's streets, boundaries, major buildings, and even ruins on the seabed. Sear worked with researchers...
April Flowers for redOrbit.com - Your Universe Online Climate change impacts on the surface of the Greenland Ice Sheet have been widely studied. An understanding, however, of the key processes in iceberg production has eluded researchers for a long time. A new study, led by the Universite Libre de Bruxelles, presents a sophisticated computer model that provides fresh insight into the impact of climate change on the production of icebergs by Greenland glaciers. The model also demonstrates...

The dusky pademelon (Thylogale brunii), also known as the dusky wallaby, is a marsupial that can be found on the Kai and Aru islands, Papua New Guinea, and in the Trans Fly savanna and grasslands ecoregion in Papua Province in Indonesia. It prefers a habitat in both arid and tropical savannahs, forests, shrublands, lowlands, and grasslands. This species was named after its discoverer, Cornelis de Bruijn, and was once commonly known as philander, or “friend of man,” and the Aru Island...
Desert greening is made up of any number of methods used to revitalize deserts. So far, only arid and semi-arid desert are meant when using this expression. The icy deserts and other types are considered to be unsuitable. The different methods include landscaping methods to reduce evaporation, erosion, consolidation of topsoil, temperature, sandstorms and more, permaculture in general, planting trees, regeneration of salty, polluted, or degenerated soils, floodwater retention and...
Mammoth Cave National Park is located in the state of Kentucky in the United States. The park holds 52,830 acres of land that was once inhabited by Native Americans. Many mummies and artifacts have been found in Mammoth Cave and surrounding caves to support this. It is thought that first man of European descent to visit the area was John Houchin or Francis Houchin. The legend says that one of the brothers was hunting a wounded bear that entered the cave to hide. The first documented discovery...
Coral reefs are submerged structures consisting of calcium carbonate secreted by corals. Coral reefs are colonies of small animals found in marine waters that enclose few nutrients. The majority of coral reefs are constructed from stony corals, which then consist of polyps that come together in groups. The polyps are like small sea anemones, to which they are very closely related. Unlike the sea anemones, coral polyps secrete hard carbonate exoskeletons which provide support and protections...
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...
