IPWireless and Huawei Co-Operate on Interoperable Solutions for Integrated Mobile Broadcast (IMB) Technology

Interoperability Testing to Include Network Infrastructure Solutions and Devices
That Utilize IMB Chipsets
SAN FRANCISCO–(Business Wire)–
IPWireless, a pioneer in developing key enabling IMB technology, and Huawei, a
leader in providing next-generation telecommunications network solutions for
operators around the world, today jointly announced that the two companies have
signed a co-operation agreement with respect to the production of each party`s
Integrated Mobile Broadcast (IMB) technology. This co-operation will include
interoperability testing (IOT) and service provider trials. These
ground-breaking interoperability tests will assure operators that they can
confidently source IMB equipment from multiple vendors and assure handset
manufacturers that their devices will be fully compatible with all IMB networks.
IMB is capable of streaming live video and broadcasting and storing popular
content on the device for later consumption – both resulting in significant
offloading of data traffic from existing 3G networks.

IPWireless and Huawei are committed to the development of an IMB ecosystem and
ensuring readiness of the technology for market as quickly as possible. IOT will
ensure compatibility between Huawei IMB base stations and IPWireless chipsets.
Both companies are also working together on several commercial and technical IMB
pilots.

IMB was defined in the 3GPP release 8 standards, and was recently endorsed by
the GSMA as their preferred method for the efficient delivery of broadcast
services. IMB enables spectrally efficient delivery of broadcast services, in
TDD spectrum based on techniques that are aligned with existing FDD WCDMA
standards. This allows for a smooth handover between IMB and existing 3G
networks. Operators can use IMB within a spectrum band that, although already
allocated to them in connection with many 3G licenses, has hitherto been unused
due to the lack of an appropriate technology.

“For IMB to achieve its full potential it is critical that solutions based on
the technology are brought to market as quickly and easily as possible,” said
William Jones, Chief Executive Officer, IPWireless. “As a leader in this
industry, we are dedicated to the development of the ecosystem so that operators
and their hardware partners are able to confidently and swiftly deploy IMB
solutions. We are delighted to be working with Huawei in ensuring that the huge
potential for mobile broadcast is realised.”

“Our operator customers are seeing an explosive growth in mobile data traffic,
driven by consumer appetite for multimedia on the move,” said Jiang Wangcheng,
President of Huawei UMTS network. “IMB provides profitability to mobile
broadband operators for their business. We are very pleased to partner with
IPWireless to explore the approach of developing profitable mobile broadband
network, and to promote the IMB technology to matureness and commercialization.”

The companies are aiming to commence interoperability testing in Q3 2010.

Five Ways to Prevent the Next Deepwater Horizon

As I write this piece on Day 70 of the Gulf oil spill, the start of the 2010 hurricane season threatens to further slow the containment of the Deepwater Horizon well.

But obviously, as we’ve moved into the third month of the ongoing disaster, the weather is only the latest of the numerous setbacks suffered in the struggle to shut down the broken well. A quick recap of the biggest challenges BP and the federal government have faced to date:

* The failure of the original containment dome installed by British Petroleum on May 7-8, clogged by the formation of chemical crystals produced from a mixture of gas and frigid seawater.
* The May 11 decision to abandon the installation of a smaller containment “top hat.”
* The failure of the May 26-29 “top kill” procedure to plug the broken blowout protector.
* The June 3 failure of the diamond-edged saw intended to produce the clean cut needed to smoothly cap the well riser. A robot, wielding shears, eventually produced a jagged cut that permitted the placement of a containment cap and the partial capture of the estimated 35,000-60,000 (and counting) barrels of oil gushing daily from the broken pipe.
* The June 23 temporary displacement of the containment cap by a robot — a mishap fortunately corrected shortly afterward.

As this suggests, there have been few decisive answers to the engineering challenges posed by Deepwater Horizon. BP’s containment efforts, and they have been herculean, numerous, and ongoing, have yet to halt the leak, and the gargantuan spill appears almost certain to continue until a relief well is completed in August. In the interim, the oil will continue to flow and to despoil the Gulf ecosystem and economy.

My own experience suggests that environmental pollution, even comparatively small discharges, can be notoriously difficult to fix. About 10 years ago, I unexpectedly found myself directing the clean-up of a building-scale environmental emergency. At the time I was managing a national commercial real estate portfolio. One of my properties was a research and development project tenanted by a manufacturing firm under a long-term lease. After years of occupancy, the tenant exercised a termination option and vacated.

Subsequent inspection and testing revealed that, in blatant violation of its lease, the tenant had left behind a witch’s brew of chemical residues — including dust from silver and mercury (both toxins) — that had penetrated the building’s plumbing and ventilation systems. Testing and clean-up — which required the use of space-suited technicians, quantities of crime scene tape, and prominent haz-mat postings — took upwards of three months. And (unlike Deepwater Horizon) we were working on firm ground, rather than at a depth of 5,000 feet below sea level.

My experience with that manufacturer leads me to believe that environmental contingency planning is typically given short shrift by many businesses, unless substantial financial liability is anticipated in the event of environmental problems. That was certainly the case with my tenant. The recently revealed shortcomings of oil industry containment plans for deepwater spills suggest that my concerns about the quality of corporate planning for environmental contingencies are hardly misplaced.

!–pagebreak–

So, how do we prevent another Deepwater Horizon? The following suggestions couple additional safety requirements for deepwater drilling with penalties to reflect the environmental and economic costs of drilling gone wrong. By enhancing safety standards and motivating companies to develop more careful contingency plans, both approaches should help protect America and the petroleum industry from the disasters that can arise in the course of doing business.

Remote shutoff capability. Require additional back-up systems to shut down offshore wells automatically. Norway and Brazil require acoustic triggers that can shut down deepwater wells remotely, in the event that mechanical systems fail. Norway has required acoustic backup systems on all rigs since 1993.

Relief well capability. At minimum, adopt Canada’s “same-season relief well capability” requirement. To receive a deepwater drilling permit in certain Canadian Arctic waters, a petroleum company must demonstrate that it has a viable system that can be deployed to drill a relief well in the same season. The Canadian requirement has been in place for 34 years. Even more to the point might be to require that a relief well be drilled at the same time as the initial well. Yes, this is an expensive precaution, but it is well below the billions that BP will spend to contain Deepwater Horizon, clean up the spill, and make good on economic claims.

Spill penalties. Impose meaningful financial penalties for deepwater spills. What is meaningful? Enough to incentivize private industry to take environmental contingency planning seriously. The $75 million per incident liability cap associated with a deepwater spill was clearly insufficient to motivate BP and its peers to develop effective contingency plans. An obvious approach would be to repeal the Oil Pollution Act’s $75 million per incident liability limit on deepwater drilling.

Onshore facilities are subject to a $350 million liability cap that can be adjusted by federal regulation — the Deepwater Horizon disaster suggests that deepwater drilling should be subject to equal or more rigorous penalties. Civil and criminal penalties in force under the Oil Pollution Act should also be re-examined for adequacy in ensuring deterrence.

Energy legislation. Also warranted: the development and passage of comprehensive energy legislation to reduce dependence on fossil fuels. As attorney Shari Shapiro, my colleague and fellow blogger, observes, “Deepwater Horizon needs to be this generation’s Love Canal moment. Congress has an unparalleled opportunity to capitalize on the anger, the shock and the awareness of the fragility of the environment to pass comprehensive energy legislation. Thank god, Love Canal moments do not come along often. It would be a pity to waste it.”

Moratorium. The Obama administration has proposed a six-month moratorium on deep water drilling. That plan has been overturned by a federal judge. A legal appeal is planned and the administration is readying an alternative moratorium approach. I’m mindful of the economic costs associated with a moratorium, but we need a breather to reassess the safety of deep water drilling. Indeed, Deepwater Horizon has already produced a temporary risk management ban on deepwater drilling — in Norway, which halted deepwater drilling in early June to evaluate the lessons of the spill.

Meanwhile, oil continues to flow into the Gulf of Mexico.

Digital Signatures Provide Competitive Advantage for Top 10 CROs

Clinical Research Organizations (CROs) accelerate investigator site initiation,
expedite clinical reporting, and support GxP audits more efficiently with
digital signatures.
SAN FRANCISCO–(Business Wire)–
Clinical Research Organizations are part of a highly collaborative clinical
trial ecosystem that demands efficiently-controlled quality and compliance
documentation. It is mission critical for CROs to create, control and share
documentation internally and externally in a trusted manner. In order to achieve
this and to simplify and expedite business processes, many CROs have adopted
e-clinical software solutions, form authoring tools, electronic workflow
systems, and quality/document management systems. However, the need to
reintroduce paper often arises when a signature or approval is required, thus
creating an automation gap that hinders efficiency, restricts collaboration, and
reduces the ROI of these business automation tools.

To close the automation gap created by the need to obtain approvals, many CROs
have deployed a digital signature solution and are now enjoying reduced costs,
expedited processes, and greater value in their services to sponsors by going
fully paperless.

Digital signatures significantly reduce the time it takes for CROs to approve
and sign documentation. In addition, they eliminate the hard costs associated
with printing, copying, and routing paper-based documentation. The elimination
of paper-based costs can save hundreds of thousands of dollars annually for even
small- to mid-sized CROs. Further, digital signatures eliminate the time lags
associated with paper-based approvals and submissions, while enhancing integrity
and reducing the compliance burdens of controlled documents.

Consider the tangible benefits of digital signatures seen by some CROs in a
variety of enterprise-wide applications, departments, and common business
processes:

Signing of site Monitoring Trip Reports by Clinical Research Associates (CRAs) -
Digital signatures allow CRAs and clinical project managers to sign and submit
reports back to sponsors within tight contract terms and eliminate the
substantial time and costs related to paper-based reporting. One top 10 CRO
estimates savings of nearly $1 million per year in priority mailing costs alone
from the use of digital signatures.

Speeding up the on-boarding and initiation of clinical sites – As part of an
Investigator Portal, investigators and institutional review boards (IRB) can
digitally sign regulatory documents (1572s, CVs, protocols, informed consents,
IRB approvals, trial agreements, etc.) via a web browser, accelerating
site/study initiation void of the expensive and time-consuming restraints
associated with paper-based approvals. Digitally signed documentation allows
easy submission to study sponsors in a format that enables electronic
submissions to regulatory authorities.

Signing quality and compliance documents used to support FDA, EMEA and Vendor
Audits – Quality controlled documents being signed include SOPs, work
instructions, training records, and project/task-specific documentation.
Sometimes, this requires integration of the digital signature technology with an
electronic document management and workflow system such as Microsoft SharePoint,
or other EDM system.

Six of the top 10 CROs use CoSign digital signatures

The ARX CoSign digital signature system is being used by 6 of the top 10 CROs
today: PRA International, PPD, CRL, Kendle International Inc., PAREXEL
International, and PharmaNet, and over 25 CROs altogether. Users include over
10,000 clinical research associates and over 10,000 investigator sites and IRBs.
With CoSign, top CROs are ensuring compliance, expediting processes, saving time
and hard costs, and gaining a competitive advantage.

Mary River restocked with iconic cod

A Fraser Coast recreational fishing group in south-east Queensland has praised a program that restocks the Mary River with its iconic cod species.

The State Government restocks the river every year with the help of volunteer stocking associations.

Martin Bellert from Sunfish says the program is critical to the survival of the endangered species.

“The Mary River Cod really needs that kick that they’re giving it with the fish stocking program, because it’s still part of the ecosystem of the Mary River,” he said.

But he warns fishers they can be fined if they keep anything they catch.

“This is a seriously depleted species actually in the Mary River and in the Clarence River in New South Wales, they’re very closely related species,” he said.

“It’s part of the repair of the ecosystem. But I’ve got to remind anglers that if you happen to hook one of these you must immediately release it in the most gentle way possible.”

Human impacts and environmental factors changing northwest Atlantic ecosystem

Washington, Sept 2 (ANI): A new report by researchers at the National Oceanic and Atmospheric Administration (NOAA) has determined that human impacts and environmental factors are changing the northwest Atlantic ecosystem.

According to the report, fish in US waters from Cape Hatteras to the Canadian border have moved away from their traditional, long-time habitats over the past four decades because of fundamental changes in the regional ecosystem.

The 2009 Ecosystem Status Report also points out the need to manage the waters off the northeastern coast of the United States as a whole rather than as a series of separate and unrelated components.

Known as the Northeast US Continental Shelf Large Marine Ecosystem (NES LME), the ecosystem spans approximately 100,000 square miles and supports some of the highest revenue-generating fisheries in the nation.

During the past 40 years, the ecosystem has experienced extensive fishing by domestic and foreign fleets, changes in ocean water temperatures due to climate change, and pressures from increasing human populations along the coast.

According to Michael Fogarty, who heads the Ecosystem Assessment Program at the Northeast Fisheries Science Center (NEFSC) of NOAA’s Fisheries Service in Woods Hole, Massachusetts, his team’s report highlights the need to understand natural and human-related changes in this region and to develop effective management and mitigation strategies.

“There are many pressures on the ecosystem including fishing, pollution, habitat loss from coastal development, and impacts on marine life from shipping and other uses of the ocean,” Fogarty said.

“In addition, changing climate conditions are warming ocean waters, changing ocean chemistry and circulation patterns, and altering atmospheric systems. These changes have, in turn, been linked to changes in the distribution and abundance of fish species in the region and their major sources of food,” he added.

The report is the first in a planned series of ecosystem status reports by Fogarty and his colleagues in the NEFSC’s Ecosystem Assessment Program to document changes in the NES LME, one of 64 regions in the world’s ocean designated as a large marine ecosystem.

Fogarty said that sustained long-term monitoring by many agencies and institutions in the Northeast region has enabled scientists and others to trace changes in the ecosystem.

“In the future, we need to continue to monitor the oceanographic, ecological, and human indicators analyzed in this report to detect any additional changes in the system. These indicators also provide important inputs to models that can be used to help guide management decisions and to forecast future changes,” he said. (ANI)

Global warming threatens existence of tropical species

Washington, August 26 (ANI): A new research has determined that global warming threatens the existence of tropical species, the ecosystem and its by-products.

The research was done by herpetologist Laurie Vitt, curator of reptiles and George Lynn Cross Research Professor at the University of Oklahoma’s Sam Noble Museum of Natural History.

Vitt has studied the ecology of lizards in rain forests around the world and, for the past 20 years, as part of a biodiversity project in the Amazon.

As a fellow researcher on a study funded by the National Science Foundation, Vitt investigated the affects of global warming on tropical lizards and the diversity of the ecosystem.

“We depend on these tropical lizards and other species of animals and plants for food, materials, and pharmaceuticals, but we are losing these species as a result of global warming,” Vitt said.

Tropical species are affected more by the very narrow temperature range of their typically warm climate than are ectotherms living where the temperatures fluctuate in greater degrees.

Even the smallest change in the tropics makes a difference to the tropical species most susceptible to climate change.

“Climatic shifts are part of our natural history, but years of research indicate global warming has increased the rate at which climate change is taking place,” said Vitt.

As populations grow around the world, so does consumption. In the densest areas of the world, the elimination of animals that feed on disease vectors, such as mosquitoes and flies, adds to our growing human health problem.

“The loss of these predators, like tropical species, upset the natural biodiversity of the ecosystem,” said Vitt. “The effects may not be so obvious in the short term, but the long-term effects will be irreversible,” he added.

“Our ability to connect with nature and better understand tropical lizards is important because these animals serve as model organisms for detecting the effects of global warming,” Vitt summarized.

“Ecosystems are complex and interdependent. When one species becomes extinct, the entire system is affected. The long-term effects on human health can be dramatic,” he said. (ANI)

How news stories rise and fall in popularity

Washington, July 14 (ANI): Cornell computer scientists say that they have successfully managed to track and analyse how news stories rise and fall in popularity, by mapping the flow of articles appearing on the Internet.

Jon Kleinberg, the Tisch University Professor of Computer Science at Cornell, postdoctoral researcher Jure Leskovec and graduate student Lars Backstrom tracked 1.6 million online news sites, including 20,000 mainstream media sites and a vast array of blogs, over the three-month period leading up to the 2008 presidential election.

The researchers have revealed that their study included a total of 90 million articles, something that makes it one of the largest analyses anywhere of online news.

They found a consistent rhythm as stories rose into prominence, and then fell off over just a few days, with a “heartbeat” pattern of handoffs between blogs and mainstream media.

In mainstream media, according to them, a story rises to prominence slowly then dies quickly.

In the blogosphere, say the researchers, stories rise in popularity very quickly but then stay around longer, as discussion goes back and forth.

Eventually though, almost every story is pushed aside by something newer, they add.

“The movement of news to the Internet makes it possible to quantify something that was otherwise very hard to measure-the temporal dynamics of the news. We want to understand the full news ecosystem, and online news is now an accurate enough reflection of the full ecosystem to make this possible. This is one (very early) step toward creating tools that would help people understand the news, where it’s coming from and how it’s arising from the confluence of many sources,” said Kleinberg.

The researchers believe that the slow rise of a new story in the mainstream results from imitation-as more sites carried a story, other sites were more likely to pick it up. But the life of a story is limited, they say, as new stories quickly push out the old.

They say that a mathematical model based on the interaction of imitation and recency predicted the pattern fairly well, while predictions based on either imitation or recency alone couldn’t come close.

They admit that their mathematical model needs to be refined, and suggest further study of how stories move between sites with opposing political orientation.

“It will be useful to further understand the roles different participants play in the process, as their collective behavior leads directly to the ways in which all of us experience news and its consequences,” the researchers concluded. (ANI)

How plants use nitrogen to invade and take over native plants

Washington, July 7 (ANI): A research at the University of Nebraska-Lincoln (UNL), US, gives important new information on how plants can change “nitrogen cycling” to gain nitrogen and how this allows plant species to invade and take over native plants.

In the research, UNL biologist Johannes Knops has demonstrated how one invasive plant species replaces native species because of its ability to take up and hold on to nitrogen.

Biologists know that nitrogen is crucial to plant growth that invasive species often grow better and acquire more nitrogen, but have been uncertain about which mechanism allows invasive species to gain an advantage.

Over seven years’ study at the Cedar Creek Ecosystem Science Reserve in central Minnesota, Knops and PhD candidate Ramesh Laungani studied the nitrogen pool and fluxes in the ecosystem that included seven grassland and forest species, including the Eastern white pine, a species that is rapidly invading Minnesota prairies.

Over time, they discovered that the pine had accrued nearly twice as much biomass as the next most productive species, and more than three times as much biomass relative to the other species.

“The higher productivity of the white pine is caused by an increased biomass nitrogen pool that was not driven by increased ecosystem level nitrogen inputs,” Knops said.

“But we found the white pine takes up nitrogen and holds on to it much longer, with leads to an accumulation of much more nitrogen in the plant and a depletion of nitrogen in the soil. We concluded high nitrogen residence time was the key mechanism driving the significantly higher plant nitrogen pool and the high productivity of that species,” he added.

In other words, pines mine the soil for organic nitrogen, decrease soil fertility and use this nitrogen to outcompete other species.

According to Knops, the higher nitrogen residence time creates a positive feedback that redistributes nitrogen from the soil into the plant’s nitrogen cycling, and this strengthened the species to support its invasion.

“What this higher nitrogen residence time means is that the plant is taking nitrogen from the soil and using it to make the plant grow more efficiently, and it also gives them an upper hand in being able to invade other species,” he said.

This study is the first to study all together and pinpoint the mechanism that explains why this pine is a successful invader. (ANI)

Green neighbors unwittingly goad one to go green too

Washington, June 30 (ANI): Individuals are more likely to register for conservation programs if their neighbors do, says a new study.

The research, to be published in the journal Proceedings of the National Academy of Sciences (PNAS) this week, is the first to focus on the phenomenon of social norms in the context of China’s conservation efforts, said scientist Jianguo “Jack” Liu of Michigan State University (MSU).

“Much of the marginal cropland in rural communities has been converted from agriculture to forests through the Grain-to-Green Program, one of the largest ‘payment for ecosystem services’ programs in the world,” said Alan Tessier, program director in the National Science Foundation (NSF)’s Division of Environmental Biology.

“Results of this study show that a community’s social norms have substantial impacts on the sustainability of these conservation investments,” the expert added.

While money is a key factor in whether people sign up for the voluntary program, peer pressure also plays a surprisingly large role, Liu said.

“That’s the power of social norms. It’s like recycling. If you see your neighbors doing it, you’re more likely to do it,” he said.

A representative survey of households in China’s Wolong Nature Reserve for giant pandas found that both government payments and social norms had “significant impacts” on citizens’ intentions of re-enrolling in the Grain to Green program.

“In other words, people’s re-enrollment intentions can be affected by the re-enrollment decisions of their neighbors and tend to conform to the majority,” says Liu. (ANI) and

58 percent of world’s seagrass meadows on the decline

Washington, June 30 (ANI): An international team of scientists has warned that accelerating losses of seagrasses across the globe threaten the immediate health and long-term sustainability of coastal ecosystems, with 58 percent of world’s seagrass meadows currently declining.

The assessment, published in the Proceedings of the National Academy of Sciences, shows an acceleration of annual seagrass loss from less than 1 percent per year before 1940 to 7 percent per year since 1990.

Based on more than 215 studies and 1,800 observations dating back to 1879, the assessment shows that seagrasses are disappearing at rates similar to coral reefs and tropical rainforests.

The team estimates that seagrasses have been disappearing at the rate of 110 square-kilometers (42.4 square-miles) per year since 1980 and cites two primary causes for the decline: direct impacts from coastal development and dredging activities, and indirect impacts of declining water quality.

“A recurring case of ‘coastal syndrome’ is causing the loss of seagrasses worldwide,” said co-author Dr. William Dennison of the University of Maryland Center for Environmental Science.

“The combination of growing urban centers, artificially hardened shorelines and declining natural resources has pushed coastal ecosystems out of balance. Globally, we lose a seagrass meadow the size of a soccer field every thirty minutes,” he added.

“While the loss of seagrasses in coastal ecosystems is daunting, the rate of this loss is even more so,” said co-author Dr. Robert Orth of the Virginia Institute of Marine Science of the College of William and Mary.

“With the loss of each meadow, we also lose the ecosystem services they provide to the fish and shellfish relying on these areas for nursery habitat,” he explained.

“The consequences of continuing losses also extend far beyond the areas where seagrasses grow, as they export energy in the form of biomass and animals to other ecosystems including marshes and coral reefs,” he added.

“With 45 percent of the world’s population living on the 5 percent of land adjacent to the coast, pressures on remaining coastal seagrass meadows are extremely intense,” said co-author Dr. Tim Carruthers of the University of Maryland Center for Environmental Science.

“As more and more people move to coastal areas, conditions only get tougher for seagrass meadows that remain,” he added.

Seagrasses profoundly influence the physical, chemical and biological environments of coastal waters.

A unique group of submerged flowering plants, seagrasses provide critical habitat for aquatic life, alter water flow and can help mitigate the impact of nutrient and sediment pollution. (ANI)

Rise in CO2 levels 200 mln yrs ago led to sudden collapse in plant biodiversity

Washington, June 19 (ANI): In a new study, scientists have found that a rise in carbon dioxide (CO2) levels 200 million years ago led to a sudden ancient collapse in plant biodiversity.

The evidence for the collapse in the plant biodiversity was unearthed by scientists in the form of 200 million-year-old fossil leaves collected in East Greenland.

The researchers were surprised to find that a likely candidate responsible for the loss of plant life was a small rise in the greenhouse gas carbon dioxide, which caused Earth’s temperature to rise.

Global warming has long been considered as the culprit for extinctions, but the surprise, according to this research, is that much less carbon dioxide gas in the atmosphere may be needed to drive an ecosystem beyond its tipping point than previously thought.

Until this research, the pace of the extinctions was thought to have been gradual, taking place over millions of years.

It has been notoriously difficult to tease out details about the pace of extinction using fossils, scientists say, because fossils can provide only snap-shots or glimpses of organisms that once lived.

Using a technique developed by scientist Peter Wagner of the Smithsonian Institution National Museum of Natural History in Washington, D.C., the researchers were able to detect, for the first time, very early signs that these ancient ecosystems were already deteriorating, before plants started going extinct.

The method reveals early warning signs that an ecosystem is in trouble in terms of extinction risk.

“The differences in species abundances for the first 20 meters of the cliffs (in East Greenland) from which the fossils were collected are of the sort you expect,” said Wagner.

“But, the final 10 meters show dramatic loses of diversity that far exceed what we can attribute to sampling error: the ecosystems were supporting fewer and fewer species,” he added.

By the year 2100, it’s expected that the level of CO2 in the modern atmosphere may reach as high as two and a half times today’s level.

“This is of course a ‘worst case scenario,” said Jennifer McElwain of University College Dublin, the research paper’s lead author. “But it’s at exactly this level (900 parts per million) at which we detected the ancient biodiversity crash,” she added.

“We must take heed of the early warning signs of deterioration in modern ecosystems,” she said.

According to the scientists, the majority of modern ecosystems have not yet reached their tipping point in response to climate change, but many have already entered a period of prolonged ecological change. (ANI)

Most polluted ecosystems recoverable within a lifetime

Washington, May 28 (ANI): An analysis of 240 independent studies by researchers at the Yale School of Forestry and Environmental Studies has revealed that most polluted or damaged ecosystems worldwide can recover within a lifetime if societies commit to their cleanup or restoration.

The Yale researchers found that forest ecosystems recovered in 42 years on average, while ocean bottoms recovered in less than 10 years.

When examined by disturbance type, ecosystems undergoing multiple, interacting disturbances recovered in 56 years, and those affected by either invasive species, mining, oil spills or trawling recovered in as little as five years.

Most ecosystems took longer to recover from human-induced disturbances than from natural events, such as hurricanes.

“The damages to these ecosystems are pretty serious,” said Oswald Schmitz, an ecology professor at the Yale School of Forestry and Environmental Studies and co-author of the meta-analysis with Yale Ph.D. student Holly Jones.

“But, the message is that if societies choose to become sustainable, ecosystems will recover. It isn’t hopeless,” he added.

The Yale analysis focuses on seven ecosystem types, including marine, forest, terrestrial, freshwater and brackish, and addresses recovery from major anthropogenic disturbances: agriculture, deforestation, eutrophication, invasive species, logging, mining, oil spills, overfishing, power plants and trawling and from the interactions of those disturbances.

Major natural disturbances, including hurricanes and cyclones, are also accounted for in the analysis.

The researchers analyzed data derived from peer-reviewed studies conducted over the past century that examined the recovery of large ecosystems following the cessation of a disturbance.

The studies measured 94 variables that were grouped into three categories: ecosystem function, animal community and plant community.

The researchers quantified the recovery of each of the variables in terms of the time it took for them to return to their pre-disturbance state.

The Yale analysis found that 83 studies demonstrated recovery for all variables; 90 reported a mixture of recovered and non-recovered variables; and 67 reported no recovery for any variable.

According to Schmitz, 15 percent of all the ecosystems in the analysis are beyond recovery.

Also, 54 percent of the studies that reported no recovery likely did not run long enough to draw definitive conclusions.

In addition, the analysis suggests that an ecosystem’s recovery may be independent of its degraded condition.

The researchers said the analysis rebuts speculation that it will take centuries or millennia for degraded ecosystems to recover and justifies an increased effort to restore degraded areas for the benefit of future generations.

“Restoration could become a more important tool in the management portfolio of conservation organizations that are entrusted to protect habitats on landscapes,” said Schmitz. (ANI)

Oil hunters started decimating whale populations as early as 1800

Washington, May 25 (ANI): One of several astonishing reconstructions of ocean life in olden days suggests that about the ocean around New Zealand teemed with about 27,000 southern right whales, about 30 times as many as today, before oil hunters started to whaling in the early 1800s.

The researchers set to make a presentation on the reconstruction at a Census of Marine Life conference, which runs from May 26 to 28, say that at about the same time, large pods of blue whales and orcas, blue sharks and thresher sharks darkened the waters off Cornwall, England, herds of harbour porpoise pursued fish upriver, and dolphins regularly played in waters inshore.

Census researchers are using such diverse sources as old ship logs, literary texts, tax accounts, newly translated legal documents and even mounted trophies to piece together images of fish of such sizes, abundance and distribution in ages past that they stagger modern imaginations.

They are also documenting the timelines over which those giant marine life populations declined.

Researchers James Barrett and Jen Harland of Cambridge University, Cluny Johnstone of York University, and Mike Richards of Germany-based Max Planck Institute reckon that a shift from eating locally-caught freshwater to marine fish species occurred around 1000 AD.

Their surmise is said to be consistent with analyses of scientifically-dated fish remains and historical data from England and northwestern Europe showing smaller freshwater fish and fewer species availability in early medieval times, likely caused by increased exploitation and pollution.

Meanwhile, Maria Lucia De Nicolo of the University of Bologna has established that new fishing boats and equipment invented in the 1500s made it possible to venture from coastal to deep sea fishing.

She says that the real revolution in marine fishing happened in the mid-1600s when pairs of boats began dragging a net.

Andy Rosenberg of the University of New Hampshire, a leader of the Census’ History of Marine Animal Population (HMAP) project and chair of the conference, says that new insights allowed by centuries of information are upending modern notions of “natural” marine life sizes, abundance, habitats and vulnerability, and causing authorities to revisit marine baselines.

The researchers believe that these insights may turn out to be useful for policy makers, who plan to use the results as a realistic baseline against which the current and future status of the marine ecosystem can be gauged.

Ian Poiner, Chair of the Census Scientific Steering Committee, says: “The insights emerging from this research of the past provide a new context for contemporary ocean management. nderstanding the magnitude and drivers of change long ago is essential to accurately interpret today’s trends and to make future projections.” (ANI)

Dual nutrient strategy vital to improve aquatic ecosystems

Washington, May 19 (ANI): A scientist has stressed on the need for a dual nutrient strategy to improve aquatic ecosystems.

Excess phosphorus and nitrogen produced by human activities on neighboring land is making its way into coastal waters and degrading both water quality and aquatic life.

Although historically the priority has been to control phosphorus, Professor Hans Paerl, from the University of North Carolina in the US, argues that nitrogen imbalance is equally damaging.

According to Professor Paerl, a dual nutrient strategy, which tackles both phosphorus and nitrogen surplus, is necessary to manage effectively this nutrient over-enrichment and resulting habitat degradation of coastal waters in the long-term.

The combination of human population growth, urbanization, and agricultural and industrial expansion is causing unprecedented and alarming rates of nutrient over-enrichment and accelerated plant growth in receiving waters worldwide.

The increasing levels of nitrogen and phosphorus are of particular concern because an excess of these two nutrients promotes accelerated production of plant-based organic matter (or eutrophication) to the extent that excessive production, including harmful algal blooms, contributes to the expansion of marine ‘dead zones’ and leads to the destruction of fisheries habitat.

The negative consequences of eutrophication have been apparent in freshwater habitats for a long time and phosphorus has been identified as the key nutrient responsible.

While freshwater lakes have, over the past few decades, received continual doses of phosphorus, many coastal systems have experienced ever-increasing nitrogen loads from rapidly growing human sources, with severe negative impacts on ecosystem structure and function.

This has led to the need for nitrogen control measures.

Professor Paerl shows that the argument for reducing surplus phosphorus alone, to control eutrophication, is idealized and conceptually and technically inapplicable to many freshwater and marine ecosystems.

He added that focusing on phosphorus alone ignores the fact that natural and human influences that affect upstream waters have significant adverse consequences on downstream waters.

Therefore, it is essential to look at nutrient control measures and their effects across the entire freshwater to marine continuum, not each one in isolation.

According to Professor Paerl, “The dual nutrient approach represents an evolutionary step in arresting eutrophication, with consideration of the larger scale freshwater-marine continuum being the driving force.” (ANI)

Facebook tops 10 most popular online brands poll in the UK

London, May 13 (ANI): A survey on the most popular online brands in the UK has revealed that Facebook tops that chart, accounting for 13 per cent of all UK internet time last month.

As per Nielsen Online, which tracked the top 10 most popular online brands, this equated to the UK users spending one in every eight minutes on the site.

The amount of UK time spent on Facebook increased by 3.8 billion minutes in April 2009 if compared with April 2008, when UK users spent 2.4 billion minutes on Facebook.

Second on the list came Windows Live, the new name for Hotmail, which includes Microsoft’s email and instant messaging tools, with users spending 4.5 billion minutes on the site, accounting for a 9.2 percent share of the total time spent on the internet by UK users in April.

Google came in third, with users spending 2.6 billion minutes on the search site, occupying 5.3 percent share of total Internet time.

The top 10 web brands accounted for 45 percent of the total UK Internet time. Consequently the other 7,625 brands tracked by Nielsen Online, have to fight for the remaining 55 per cent of time Britons spend online.

“The Internet is a complex and varied ecosystem and I think most people would be surprised by just how much time is accounted for by a relatively few brands who, in turn, are increasing their share of the pie,” the Telegraph quoted a Nielsen Online spokesperson as saying.

In April 2009, the average Briton spent 22 hours 20 minutes online or using internet-related applications.

This represents a 34 percent increase on a year ago when the figure was 16 hours 36 minutes.

The top 10 most used web brands in the UK during April 2009, according to total minutes spent on the site:

1. Facebook – 6.2 billion minutes

2. Windows Live – 4.5 billion minutes

3. Google – 2.6 billion minutes

4. eBay – 2.0 billion minutes

5. Yahoo! – 1.7 billion minutes

6. AOL – 1.5 billion minutes

7. BBC – 1.1 billion minutes

8. YouTube – 898 million minutes

9. Microsoft – 733 million minutes

10. Apple – 719 million minutes (ANI)

Scientists find undersea volcano has grown a massive cone

Washington, May 6 (ANI): Marine scientists, on an expedition to an erupting undersea volcano near the Island of Guam, have discovered that it appears to be continuously active, has grown a new cone during the past three years, and its activity supports a unique biological community thriving despite the eruptions.

The international science team on the expedition, funded by the National Science Foundation (NSF), captured dramatic new information about the eruptive activity of NW Rota-1.

“NW Rota-1 remains the only place on Earth where a deep submarine volcano has ever been directly observed while erupting,” said Barbara Ransom, program director in NSF’s Division of Ocean Sciences, which funded the research.

Scientists first observed eruptions at NW Rota-1 in 2004 and again in 2006, according to Bill Chadwick, an Oregon State University (OSU) volcanologist and chief investigator on the expedition.

This time, however, they discovered that the volcano had built a new cone 40 meters high and 300 meters wide.

“As the cone has grown, we’ve seen a significant increase in the population of animals that lives atop the volcano. We’re trying to determine if there is a direct connection between the increase in the volcanic activity and that population increase,” Chadwick said.

Animals in this unusual ecosystem include shrimp, crab, limpets and barnacles, some of which are new species.

“They’re specially adapted to their environment, and are thriving in harsh chemical conditions that would be toxic to normal marine life,” said Chadwick. “Life here is actually nourished by the erupting volcano,” he added.

According to Verena Tunnicliffe, a biologist from the University of Victoria, most of the animals are dependent on diffuse hydrothermal venting that provides basic food in the form of bacterial filaments coating the rocks.

“It appears that since 2006 the diffuse venting has spread and, with it, the vent animals,” Tunnicliffe said. “There is now a very large biomass of shrimp on the volcano, and two species are able to cope with the volcanic conditions,” she added.

The shrimp reveal intriguing adaptations to volcano living.

“The ‘Loihi’ shrimp has adapted to grazing the bacterial filaments with tiny claws like garden shears,” said Tunnicliffe. “The second shrimp is a new species – they also graze as juveniles, but as they grow to adult stage, their front claws enlarge and they become predators,” she added.

The new studies are important because NW Rota-1 provides a one-of-a-kind natural laboratory for the investigation of undersea volcanic activity and its relation to chemical-based ecosystems at hydrothermal vents, where life on Earth may have originated. (ANI)

China’s plants absorb a third of its carbon emissions

London, April 23 (ANI): In a new study, an international team of scientists has found that the plants in China absorb a third of its carbon emissions.

According to a report in Nature News, similar work has been done for the United States, but this study provides the first comprehensive analysis of China’s terrestrial carbon uptake, which is critical for calculating the country’s net emissions.

Led by Shilong Piao, an ecologist at Peking University in Beijing, the team estimated carbon uptake during the 1980s and 1990s using three different methods: ecosystem modelling, plant and soil inventories, and an analysis of atmospheric CO2 trends.

The authors estimate a net carbon sink of between 0.19 and 0.26 billion tonnes of carbon per year, which translates to 28 to 37 percent of China’s emissions during the period in question.

“Everyone has been scrambling around to come up with an estimate for China, because we don’t have a lot of information,” said Kevin Gurney, a climate researcher at Purdue University in West Lafayette, Indiana.

“They really have been methodologically thorough. They have tackled it from three different angles, and the nice thing is that all three of those converge on the same estimate,” he added.

“This is an impressive paper,” said Gregg Marland, a climate researcher at Oak Ridge National Laboratory.

He credits the researchers with analyzing the question in three ways and getting a fair amount of agreement in their results.

“In spite of that, there is still a considerable amount of uncertainty, and that uncertainty cascades through the system,” he said.

Although studies such as this can give broad estimates of carbon uptake, Marland said that the only way to pin down some of these numbers might be via satellites, like the Orbiting Carbon Observatory that plunged into the sea earlier this year.

“It’s going to be a long while before we have the kind of satellite data that we want,” he added. (ANI)

iXiGO.com to support international airlines’ move to zero commissions in India

New Delhi, Apr 16 (ANI/Business Wire India): iXiGO.com, India’s fastest growing travel site, today announced that it supported the move by international airlines to zero commissions for travel agents and that it will continue working strategically alongside airlines in growing their direct sales and reducing their distribution cost.

14 international carriers in India have recently moved to zero commissions with a transaction fee system.

These include Singapore Airlines, Lufthansa, American Airlines, Austrian Airlines, Qatar Airways, Air France, KLM, Delta Airlines, British Airways, Continental Airlines and Finnair.

Though they acknowledge travel agents as an integral part of their business, they remain committed to reducing travel agency commissions to zero, pushing travel agencies to a transaction fee (or service fee) model.

This is in line with their global policies and an increased focus on direct-selling through their own website with web-only fares, lowest fare guarantees and exclusive on-site promotions.

Announcing the company’s stand on the issue, Aloke Bajpai, Founder-CEO, iXiGO.com said, “iXiGO remains committed to growing direct web-sales for international airlines just like we have already successfully done for domestic carriers. We are in the process of signing partnerships with all major international airlines and we believe that the move to zero commissions will be beneficial for the entire travel ecosystem in the long-run. Instead of focusing on commissions, as an industry we need to focus on the value delivered to the consumer. Selling and distribution costs are a major burden on airline P and Ls and it is our responsibility to enable more efficiency in their cost of sales.”

iXiGO.com’s unique business-model has introduced a paradigm-shift in travel bookings and has made it India’s biggest airline-direct search engine enabling efficient customer acquisition for all airlines in India.

Since bookings through iXiGO.com’s engine happen by transferring customers onto airline websites, the airline owns the customer and benefits from ancillary revenue and brand loyalty due to more effective marketing and direct distribution on the Internet. It is estimated that if efficient direct selling platforms such as travel search engines can transition just 10 per cent of sales directly to the airline sites from intermediaries, airlines in India would cumulatively save at least Rs. 100 crores every year in distribution costs.

Nitin Gurha, VP, Travel Partnerships, iXiGO.com said, “Travel agents will need to adapt to the transaction fee model prevalent in all large markets globally. They can make much better margins on hotels, tours and package bookings and also by offering value-added services like visas, insurance etc, so the impact on travel agency bottom-lines should only be marginal. Globally, travel agents have evolved into travel consultants and we don’t see a reason for that not happening in India”.

iXiGO.com, launched in June 2007, has grown exponentially in the last 12 months and is one of the biggest affiliates of airlines in India, driving transactions worth Rs.18 crores every month on airline sites.

In addition to airlines, iXiGO.com searches more than 220,000 hotels across the world and bus operators within India. (ANI)
