Peru says 5,000 birds, nearly 900 dolphins dead

AFP Yahoo News 10 May 12;

The Peruvian government said Wednesday that 5,000 birds, mostly pelicans, and nearly 900 dolphins have died off the country's northern coast, possibly due to rising temperatures in Pacific waters.

The country's northern beaches were earlier this week declared off-limits as scientists scrambled to pin down what was causing such a massive toll, with non-government organizations blaming oil exploration work.

But Peru's deputy environment minister Gabriel Quijandria, disputed this and said warming waters, which disturbs species' food supplies, was a possible cause.

He said that although tests conducted on 877 dolphins found dead on the coast had not been completed, contamination from heavy metals or the presence of bacterial infections was not responsible.

It is probable that the phenomenon "will extend to other coastal areas," Quijandria said, noting that there could be a resulting increase in the numbers of birds and other sea life killed.

The South American nation's health ministry declared an alert at the weekend, urging the public to stay away from the beaches around Lima and on the northern coast until the cause of death of marine life is known.

One non-government conservation organization, known as ORCA, has blamed the dolphin deaths on oil exploration activities in the area, which it claims produces noises which are having an acoustic impact on the mammals.

A representative from the group, Carlos Yaipen, said Wednesday it had tested 30 dead specimens and found broken ears and damaged organs consistent with the victims suffering "the bends," also known as decompression sickness.

Weather expert Abraham Levy told AFP on Tuesday that the warming of the Pacific waters due to El Nino could be to blame.

Asia-Pacific needs greening, UNDP finds

United Press International 10 May 12;

JAKARTA, May 10 (UPI) -- With Asian economies producing close to half of the world's greenhouse gas emissions, they need to find the right balance for prosperity, a U.N. report finds.

A report from the U.N. Development Program, "Asia-Pacific Human Development Report 2012 -- One Planet to Share: Sustaining Human Progress in a Changing Climate," states the region needs to find the right balance between prosperity and environmental sustainability.

"The world's common future will be hugely affected by the choices that are made in Asia and the Pacific on a low carbon growth path," Ajay Chhibber, UNDP regional director for Asia and the Pacific, said in a statement. "The goal is clear: reduce poverty, increase prosperity but leave a smaller carbon footprint."

The 269-page report says Asian and Pacific economies need to change the way they practice agriculture, manufacture goods and produce energy.

This will mean "moving to greener, more resilient, lower-emission options that not only sustain the environment but also offer opportunities to the poor for employment and income," the report states.

The UNDP estimates economies in the region generate 37 percent of global emissions through agricultural production, land-use changes and deforestation.

Scientists Urge Action On World's Biggest Problems

Chris Wickham PlanetArk 11 May 12;

Scientists from 15 countries are calling for a better political response to the provision of water and energy to meet the challenge of feeding a world of 9 billion people within 30 years.

The joint statement by some of the world's leading science academies was issued on Thursday ahead of the G8 summit in the United States. It is part of the annual lobbying effort aimed at focusing the attention of world leaders on issues the scientific community regards as crucial.

For the first time, the scientists argue that looming shortages in water and energy supplies should be treated as a single issue.

"Major stresses on availability of energy and water are already being felt in many countries and regions and more are foreseeable," the joint statement said.

Fossil fuel, nuclear and hydropower are still providing the bulk of the world's energy and they all rely heavily on the supply of water for cooling, running steam turbines or direct power generation. Conversely, large amounts of energy are used in pumping, purifying and desalinating water around the globe.

"Without considering water and energy together, inefficiencies will occur, increasing shortages of both," the statement warns. Politicians should pursue policies that integrate the two and emphasize the need for conservation, efficiency and cooperation across national borders.

DISASTERS CERTAIN TO HAPPEN

The world also needs to increase its resilience against disasters like those which result from tsunamis, earthquakes and levees that fail in the face of rising sea levels.

"Disasters are absolutely certain to happen," Michael Clegg of the U.S. National Academy of Sciences told Reuters, adding growth in the global population, from 7 billion now, was focused on coastal areas that are more vulnerable, making it "more important that we design for resilience."

The scientists said global annual losses from natural disasters exceeded $200 billion in 2005, 2008 and 2011 but loss of life was generally much lower in developed countries.

Governments should focus efforts on improving public health systems, strengthening building standards and better information technology that enables faster warnings and response.

Signatories of the statement are from the leading science academies in the United States, Russia, China, Britain, Brazil, Canada, France, Germany, India, Indonesia, Italy, Japan, Mexico, Morocco and South Africa.

They also call for better measurement of planet-warming greenhouse gas emissions and more solid data country by country on natural resources like forests, which absorb some of the most damaging carbon emissions.

"More accurate and standardized methods for estimating human and natural sources and sinks of greenhouse gases are needed as a prerequisite for an international climate treaty and to determine the effectiveness of national emission-reduction programs," they said.

Clegg said that despite the widespread acceptance of the need to reduce greenhouse gases, there is still a lot of uncertainty about, and a lack of standardization in, the methods for measuring those emissions.

"There is a great need to develop more accurate approaches," he said, adding that it was a fundamental building block for the world's response to climate change but "getting a correct measurement ... is challenging."

The statement urges politicians to "give greater consideration to the vital role science and technology could play in addressing some of the planet's most pressing challenges".

Island nations lay out green agenda

UPI 10 May 12;

BRIDGETOWN, Barbados, May 10 (UPI) -- A consortium of island nations announced the signing of a declaration in Barbados calling for a move toward renewable energy and environmental stewardship.

Twenty small island developing states, dubbed SIDS, signed a declaration in Barbados that outlines ways to combat poverty through economic growth by way of an affordable renewable energy strategy.

The so-called Barbados Declaration states SIDS could develop renewable energy programs such as wind, solar, geothermal and marine energy where commercially feasible.

Host country Barbados committed to getting 29 percent of its electricity from renewable energy by 2029. Seychelles aims to get 15 percent of its energy from renewable resources by 2030, while Maldives said it expects to become carbon neutral by 2020.

Rising sea levels and global climate change threaten to submerge the Maldives within decades.

"(T)hese technologies must be made accessible, affordable and adaptable to the needs and particular circumstances of SIDS communities," the declaration read. "In this regard, we strongly urge the international community, particularly developed countries, to ensure the provision of financial resources, technology transfer and capacity building to SIDS."

The declaration was adopted one month ahead of the U.N. Conference on Sustainable Development in Rio de Janeiro.

Political shift will make or break Rio+20 summit

Valerie Volcovici and Nina Chestney Reuters 10 May 12;

WASHINGTON/LONDON | Thu May 10, 2012 1:01pm EDT

(Reuters) - The shifting sands of geopolitics, marked by rapid growth of big, emerging economies such as Brazil and China while traditionally rich countries fall behind, could undermine progress to define sustainable development goals at a United Nations conference next month.

New divisions between old allies are adding to familiar disputes over finance and responsibility as preparatory talks in New York last week failed to find consensus, causing the United Nations to add an extra round of talks later this month.

The Rio+20 summit in Brazil from June 20-22 is expected to attract more than 50,000 participants from governments, companies and environmental and lobby groups.

It will try to hammer out aspirational, rather than mandatory sustainable development goals across seven core themes - including food security, water and energy - but will not seek to repeat the outcome of the Rio Earth Summit 20 years ago, which led to the Kyoto Protocol on capping greenhouse gas emissions and a treaty on biodiversity.

One reason for the change in goals is the shift in global geopolitics that has come with the rising strength of countries like Brazil, South Africa, India and China - which are still classed as "developing" countries despite their rapid growth, while the traditional "developed" nations like those of Europe, the United States and Japan struggle with slower growth.

"The world in 1992 is not the same as in 2012. Each country will now have to bear responsibility for ensuring sustainability," European Commissioner for Environment Janez Potocnik told Reuters.

"The negotiations ... are worrying at this stage. The pace is relatively slow and there is some lack of focus."

The shift has strengthened some developing countries and changed how countries approach certain issues, said Samantha Smith, leader of global climate and energy initiative for environmental group WWF.

It has created new alliances between countries and opened new divisions, which is undermining progress on many issues, particularly financing development goals.

"What is happening in the negotiations reflects what is happening in geopolitics in general," Smith said.

In a sign of the challenge facing government officials, the U.N. added an extra five days of talks in New York from May 29 to June 2 to salvage a negotiating text that has multiplied in size but has been diluted, after failing to make enough progress at last week's round of talks.

NEW STRENGTH

While traditional rifts between rich and poorer nations linger on issues like finance, established groups of allies are branching out or splitting up in a reflection of their emerging economic status.

The so-called G77 and China coalition of developing countries has started to split into individual nations and groups, and a group comprising Brazil, South Africa, India and China (BASIC) is gaining strength and prepared a parallel negotiating text to put forward next month, sources said.

The issue of raising finance is a major stumbling block, echoing long-standing disagreements in separate U.N. talks for a global emissions-cutting pact.

In that arena, industrialized countries have long been accused of not raising finance quickly enough to help more vulnerable countries adapt to climate change, and a fund designed to help channel up to $100 billion a year in aid is still an empty shell.

Traditionally richer nations like those in the European Union, the United States and Japan have been facing tougher economic times, with many countries imposing austerity measures on their citizens and cutting spending dramatically.

Some developing countries are concerned that the tough economic backdrop will provide an excuse for richer nations to back out of old financial commitments and avoid new ones.

"We hope that the financial crisis, which has hit both the developed and developing world does not lead us being short-sighted with respect to the Rio outcome," said Marlene Moses, chair of the Alliance of Small Island States negotiating bloc.

"We've seen a lack of ambition from some of our partners with respect to the outcome document, but we're optimistic that we can bring them on board," she added.

The European Commission, the EU's executive arm, which is sending representatives from its climate, environment and development divisions to Rio, as well as Commission President Jose Barroso, is still hopeful of a concrete outcome to the conference at final talks in June.

"Even if the EU is in the worst economic crisis ever, it will still deliver on its aid commitments and recognizes additional efforts are needed," said Potocnik.

"A range of resources need to be mobilized, including international, public and private sources. ... Enabling conditions, such as phasing out environmentally harmful subsidies (on fossil fuels), is being talked about and really makes sense."

ARGUMENT OVER AID

The original U.N. Earth Summit 20 years ago agreed that around $125 billion in grants or concessions was needed from the international community in development aid by 2000, or around 0.7 percent of gross domestic product.

Some developing countries are accusing donor countries such as Europe, the United States and Japan of failing to deliver the aid and want confirmation in the Rio+20 text that they will strive to commit to that original 0.7 percent goal, which some donor countries oppose.

"There has been a bit of a blame game where they (developing countries) are trying to frame this as a lack of progress," said Antonio Hill, policy adviser at aid group Oxfam.

He said the Rio summit is unlikely to consider financing ideas favored by some rich countries, such as a financial transaction tax or levies on bunker fuels and the aviation sector.

"It's one of the things that is part of the back and forth tension between industrialized and developing countries. It is going to be very difficult to see much progress on financing that is unilateral," Hill added.

GREEN ECONOMY

The idea of a "green economy" is another contentious issue.

The United Nations Environment Programme defines a "green economy" as one that improves human well-being and social equity while reducing environmental risks and scarcities.

The United Nations last week said some developed countries have "embraced" the green economy concept as a common road map for sustainable development.

But many developing countries are concerned that the concept might not go far enough to promote social justice and suspect it could bring about trade disputes and reduce competitiveness.

"I have the feeling that the logic and importance of a green economy is not yet being taken as something which is really needed for future sustainability," Potocnik said.

"We absolutely need new energy in the negotiating process to move to the stage where we get a concrete outcome in Rio."

First green library for kids taking root here

Leslie Kay Lim Straits Times 10 May 12;

IN A year, children visiting the National Library in Victoria Street will be able to step into an 'enchanted forest' containing a collection of green-themed books, programmes and displays.

Four- to 12-year-olds will even be able to curl up with books in their very own tree house there.

The facility, the world's first green library for children, comes courtesy of the National Library Board (NLB) and property developer City Developments, for which this is a project in corporate citizenry.

Called 'My Tree House', the 500 sq m library will have 70,000 books, many of them with a nod to nature themes.

NLB chief executive Elaine Ng said the library aims to familiarise children with the environment and green practices. 'We hope this will contribute to a new generation of nature lovers,' she added.

My Tree House will be in the current children's area in the basement of the National Library Building.

City Developments and its partners Interface and Royal Philips Electronics have pledged to provide the expertise and resources for the green library. Their joint experience with green-building innovations means the library will be built with green materials and practices.

The tree house centrepiece, for instance, will be made of recycled timber, PVC pipes, aluminium cans and plastic bottles; the library will be kitted out with carpets made of 70 per cent recyclable materials and energy-efficient LED lighting as well.

The design firm for the project, ADDP Architects, has a track record with green buildings; its leading design consultant Tang Kok Thye was recently named Green Architect of the Year by the Building and Construction Authority.

Mr Tang said the challenges in the project came in the retrofitting of the library's space, and the changes made to the original design.

Along the way, his team had input from what he called 'little consultants': These likely users of the library said they preferred slopes over stairs. They also said the phrase 'green' brought to mind vegetables more than the environment, which is how the tree house concept evolved.

The library's interior will have high-tech interactive displays such as a shadow wall and a tree stump with rings reacting to sound and temperature.

Most of the library will be built off-site to minimise interruptions to the library's operations. The NLB hopes to showcase the green library at the World Library Information Congress to be hosted here in August next year.

Encyclopedia of Life Reaches Historic One Million Species Pages Milestone

ScienceDaily 9 May 12;

The Encyclopedia of Life has surged past one million pages of content with the addition of hundreds of thousands of new images and specimen data from the Smithsonian Institution's National Museum of Natural History (NMNH). Launched in 2007 with the support of leading scientific organizations around the world, the Encyclopedia of Life provides global access to knowledge about life on Earth by building a web page for each of the 1.9 million recognized species.

The new content from NMNH recently added to EOL includes type specimen information from the botany, entomology, vertebrate zoology and invertebrate zoology departments. In taxonomy, type specimens are the first found material from which new species are scientifically defined and given names. These specimens are vital resources for scientists who study the classification of organisms and to all studies of comparative biology.

"The Encyclopedia of Life is a consortium of partners who generate and integrate biodiversity information worldwide. To achieve our ambitious goals, we have to continuously increase the number of species pages and the amount of trusted information in each of them," said Dr. Erick Mata, EOL Executive Director. "Thanks to the hard work of our international collaborators, we hit the one million page mark with plenty of momentum for the next five years."

The new images now available on EOL include specimen photos of bones and skins, mounted specimens, x-rays, and photos from collecting expeditions. Some highlights include image galleries for pressed plants, mollusk shells and other marine invertebrates, insects, fish and herpetology.

Reaching the milestone of one million pages of rich content underscores how far the EOL initiative has come since its inception five years ago. When EOL first launched, it offered only 30,000 species pages from fewer than a dozen content partners. Today, EOL has more than 200 collaborators around the world, a global member community, and active contributors who share their time, creativity and knowledge through EOL.

"This isn't just a big milestone for us -- it's also an important one for all of our users, supporters and partners who have helped build the global EOL network," said Dr. Cynthia Parr, Director of EOL's Species Pages Group. "We are well on our way towards building a resource that will have maximum impact on the understanding and conservation of biological diversity."

Citizen Backlash Keeps Malaysia Rare Earth Plant On Hold

Siva Sithraputhran PlanetArk 10 May 12;

The expensive machinery lies silent, idling as Malaysia's government weighs a delicate decision to allow shipments of raw material to arrive from Australia and finally start operations at the world's largest rare earths plant outside China.

At the industrial estate on the country's east coast, 20 or so protesters gathered in the searing afternoon heat have begun a chant. "No to Lynas. Lynas go home!".

The handful of demonstrators seems an unlikely obstacle to plans by Australia's Lynas Corp to build its company-making 2.5 billion ringgit ($800 million) plant, seen as crucial to challenging China's near monopoly on the production of rare earths, used in items ranging from smartphones to smart bombs.

But the expanding protest movement they represent, feeding off broader frustrations with Malaysia's government as elections loom, has already delayed the project by eight months and cast a shadow over its future.

The resistance - fed by social networks and Malaysia's increasingly lively independent online media - also raises broader questions over the global expansion of an industry that has created huge environmental problems in China, which currently accounts for about 95 percent of global supply.

"Western countries don't want it. Why should we in Malaysia?," said Norizan Mokhtar, who lives less than 10 km (6 miles) from the plant in the industrial area of Gebeng, close to fishing villages and Kuantan, a city of half a million people.

"My youngest is six, the effects might not be seen now but in the future. We eat fish every day, what if there is radiation?"

She's afraid controls on the plant will become slack after the first few years.

Lynas has been plagued by delays and controversy in Malaysia since it broke ground on the plant two years ago with the aim of easing China's grip on the supply of rare earths and capitalizing on rising prices for the material.

Its share price has halved since early last year as investors worry that it will lose out in the race to feed surging world demand.

Lynas has orders covering its first 10 years of production. Japan, the world's biggest consumer of rare earths, is counting on Lynas to supply 8,500 tonnes a year by early 2013.

"Our customers are waiting," Mashal Ahmad, the managing director of the Lynas plant, told reporters during a tour of the plant for media last month.

"We have nothing to hide," he said, adding that "too much misinformation" had been spread about the company.

CAUGHT OFF-GUARD

Prized for their magnetism, luminescence and strength, world consumption of rare earths is estimated to rise to around 185,000 metric tonnes (203,928 tons) a year by 2015, from 136,000 tonnes in 2010.

China imposed export quotas in 2009 to fight pollution caused by illegal mining and processing, turning up the pressure to find alternative sources.

The Lynas plant is one of a handful under construction. It is 98 percent complete and would supply about 11,000 tonnes in its first year, eventually rising to 22,000 tonnes.

Elsewhere, Canada's Great Western Minerals is teaming up with a Chinese group to build a rare earth processing plant in South Africa, while U.S. firm Molycorp is set to churn out just under 20,000 metric tons of rare earth oxide this year at its site near California's Death Valley.

The Malaysian protest movement gathered strength last year after allegations - denied by Lynas - that it was cutting corners on safety, fanning fears that radioactive run-off from waste material stored at the plant could seep into the local water system after being chemically treated.

An estimated 8,000 people rallied against Lynas in Kuantan in February and the issue has been seized on by the country's opposition to show the government is out of touch with citizens' concerns.

Malaysia's government at first showed few signs of heeding the protesters' concerns, but it appears to have been caught off-guard this year by the strength of opposition to the plant as it prepares for a closely run election within months.

Pahang, the state where the plant is being built, is a key stronghold for the long-ruling Barisan Nasional coalition that it can ill-afford to lose. Responding to lobbying by citizens' groups, the government set up a parliamentary select committee in March to look into the safety of the plant, after halting a conditional temporary operating license granted in February.

A decision is expected after the committee presents its findings at the end of June.

Prime Minister Najib Razak has vowed the government will not allow Lynas to operate the plant if there is any doubt over its safety. But he must also weigh the costs of sending a negative signal to foreign investors as he tries to reinvigorate the economy of the Southeast Asian country.

"We will never compromise the safety of the people and the environment," he said in a radio broadcast last month.

Lynas officials say they are confident the plant will win approval in coming months. Opponents suspect the government is waiting until after the election to approve the plant at a less sensitive time.

"The timing could be all too convenient," said Fuziah Salleh, a local opposition member of parliament who has thrown her weight behind the protest movement. "Basically it is a delay tactic until approval."

Fuziah and leaders of the protest movement "Stop Lynas, Save Malaysia" say they will continue to fight against Lynas in the court if it wins approval, signaling more uncertainty ahead.

The opposition - which made historic gains in 2008 polls and has an outside chance of winning the next election - has said it will scrap the Lynas project altogether if it takes government.

TAINTED HISTORY

Opponents say the Lynas plant doesn't meet with best practice standards for the industry as it is too close to heavily populated areas and in a place where the ground water level is high. Molycorp's plant in California, by comparison, is situated far from residential areas in an arid climate.

"There never was any public consultation before the building of the plant got underway. I faced resistance from the start," said Fuziah.

If the protesters' views are trenchant, then Lynas' resolve is also hardening. The company has started legal action against a Malaysian news portal and a protest group for defamation.

Rare earths have a tainted history in Malaysia. In 1992, a unit of Mitsubishi Corp closed a rare earths plant in Bukit Merah in Perak state amid acrimony over radioactive contamination. Residents of Bukit Merah say they have suffered a high numbers of birth defects and leukemia.

Lynas says comparisons with Bukit Merah are unfair because the raw material there was over 40 times more radioactive than the concentrate to be used at its plant.

It says commercial - not environmental - reasons brought it to Malaysia, where the government has granted the company "pioneer" status, giving it a 10-year tax holiday.

Lynas says it has added earthen fill to the site for the storage facility to double the distance between waste products and the water table to 4.1 meters (14 feet).

The waste will contain low levels of thorium, a radioactive chemical which can cause cancer, but the concentration of thorium is very low and stays low, it says.

But it isn't clear how long the waste matter will be stored at the plant. Lynas says its storage facility has been built to a standard that would allow the waste to be stored permanently, although it only expects storage for 17 or 18 years. It hopes to sell the waste as a base for road construction after reducing its radioactivity concentration to safe levels.

Treated waste water from the plant will go into the Balok river at an average rate of 213 cubic meters (7500 cubic feet) per hour, raising concerns about the impact on marine life and on the livelihoods of the fishermen along the coast. Officials at Lynas say the concerns are unfounded and the discharged water will meet with Malaysian regulations.

From her perch close to the Balok river, Kak Su, who sells the daily catch local fishermen bring in, smiles quietly. She is resigned to her fate.

"The government will decide, I don't think they'll make a bad decision," she says. "I don't think the protesters will get anywhere," she adds.

App to fight wildlife trafficking in Cambodia

TRAFFIC 9 May 12;

9th May 2012—A new iPhone app informing travellers to Cambodia about species threatened by trade and letting them take action in the fight against wildlife trafficking has been launched by a partnership that includes TRAFFIC.

The educational app developed by Wildlife Alliance, Trigger LLC, Jeff Corwin Connect and TRAFFIC provides both a catalogue of South-East Asian animal and plant species, showcases the forms in which endangered wildlife is most frequently traded, which are the most threatened and how to pick them out by their unique features.

It also features a built-in system that allows users to report the suspected illegal sale of wildlife and wildlife based products directly to Wildlife Alliance’s Rapid Rescue Team.

The app is designed to aid the ongoing efforts to preserve the region’s wildlife. It raises the profile of many wild plant and animal species that are trafficked for traditional medicine, exotic meat and pets. The information enables tourists to make responsible choices about their purchases while on holiday and gives them the opportunity to play an active role in preserving Cambodia’s natural heritage.

The app opens with an introduction by Jeff Corwin from the Animal Planet and features maps, photographs and a list of markets where visitors might see wildlife in trade. It is free to download.

One-Quarter of Grouper Species Being Fished to Extinction

ScienceDaily 9 May 12;

Groupers, a family of fishes often found in coral reefs and prized for their quality of flesh, are facing critical threats to their survival. As part of the International Union for Conservation of Nature (IUCN) Species Survival Commission, a team of scientists has spent the past ten years assessing the status of 163 grouper species worldwide. They report that 20 species (12%) are at risk of extinction if current overfishing trends continue, and an additional 22 species (13%) are Near Threatened.

These findings were published online on April 28 in the journal Fish and Fisheries.

"Fish are one of the last animal resources commercially harvested from the wild by humans, and groupers are among the most desirable fishes," said Dr. Luiz Rocha, Curator of Ichthyology at the California Academy of Sciences, and one of the paper's authors. "Unfortunately, the false perception that marine resources are infinite is still common in our society, and in order to preserve groupers and other marine resources we need to reverse this old mentality."

The team estimates that at least 90,000,000 groupers were captured in 2009. This represents more than 275,000 metric tonnes of fish, an increase of 25% from 1999, and 1600% greater than 1950 figures. The Caribbean Sea, coastal Brazil, and Southeast Asia are home to a disproportionately high number of the 20 Threatened grouper species. (A species is considered "Threatened" if it is Critically Endangered, Endangered, or Vulnerable under IUCN criteria.)

Groupers are among the highest priced market reef species (estimated to be a multi-billion dollar per year industry), are highly regarded for the quality of their flesh, and are often among the first reef fishes to be overexploited. Their disappearance from coral reefs could upset the ecological balance of these threatened ecosystems, since they are ubiquitous predators and may play a large role in controlling the abundance of animals farther down the food chain.

Unfortunately, groupers take many years (typically 5-10) to become sexually mature, making them vulnerable for a relatively long time before they can reproduce and replenish their populations. In addition, fisheries have exploited their natural behavior of gathering in great numbers during the breeding season. The scientists also conclude that grouper farming (mariculture) has not mitigated overfishing in the wild.

Although the prognosis is poor for the restoration and successful conservation of Threatened grouper species, the authors do recommend some courses of action, including optimizing the size and location of Marine Protected Areas, minimum size limits for individual fish, quotas on the amount of catch, limits on the number of fishers, and seasonal protection during the breeding season. However, the scientists stress that "community awareness and acceptance, and effective enforcement are paramount" for successful implementation, as well as "action at the consumer end of the supply chain by empowering customers to make better seafood choices."

New spider species found in urban setting

UPI 8 May 12;


Trapdoor spider. Credit: Graham Manning

AUBURN, Calif., May 8 (UPI) -- Researchers at Auburn University say they've discovered a previously unknown trapdoor spider species in the heart of the city of Auburn, Ala.

The discovery in a long-urbanized area highlights how much remains to be revealed about life in our own world, Auburn biology Professor Jason Bond said.

"The discovery of a new species in a well-developed area like this further demonstrates the amount of biodiversity on our planet that remains unknown; we know so little about our home planet and the other organisms that inhabit it with us," Bond said.

The new species, Myrmekiaphila tigris, has been affectionately dubbed the Auburn Tiger Trapdoor spider in honor of Auburn University's costumed Tiger mascot, Aubie, a university release reported Tuesday.

Trapdoor spiders construct subterranean burrows that they cover with a hinged door made of a mixture of silk and soil, and females spend nearly their entire lives in the single silk-lined burrow from which they forage as sit-and-wait predators.

Burrows can often be found in relatively young, secondary growth forests in natural areas of urban neighborhoods, the researchers said.

The study was published in the open access journal ZooKeys
