Two new stingrays found in the Amazon are not only revealing much about the species but are also proving great indicators of ecological change Crocodile hunter Steve Irwin’s well-publicised death in 2006 from a stingray attack only heightened public fascination with the animals. Their stings, located on the tail, are sharp, with backward-pointing serrations and venom from mucous secretions at their bases. Most human stings result from bathers stepping on an unsuspecting stingray, innocently resting on the sea bottom, which produces a defensive reflex of the tail forward. But stingrays are not limited to saltwater. Although the Potamotrygonidae family of freshwater stingrays has been known since 1843, two remarkable new species from South America were recently described. Both are nearly circular in shape, the most round disc of any of the current tally of approximately 200 known species of stingrays. The genus was named Heliotrygon , a combination of helio – sun – and trygon, which means ray. Although the two species are new to science, specimens of the genus have shown up in the aquarium fish trade under common names such as “round” or “pancake” rays. These species have tiny eyes and live in murky waters of the central channel areas of Amazonian rivers, coming closer to shore mostly at night to feed. Even though they have reduced mouths that are located away from their snouts, they eat fish almost exclusively. You may be asking how a flat ray, with a tiny mouth located on the underside of its body, could catch fish. Using their “lateral line system”, sense organs that can detect movements and pressure changes in surrounding water, they spot their prey, thrust upward, lift the snouts and quickly open their small but very strong mouths to swallow a fish almost whole. One specimen examined by x-ray had a large catfish in its gut, spines and all. Although these rays are the last thing seen by many fish, they present no danger to us. The stings of Heliotrygon gomesi are among the smallest of all stingrays. A specimen 70cm across has a sting only about as long as the fingernail of your pinky and only one-tenth as wide, incapable of inflicting much damage. Dr Marcelo de Carvalho of the Universidade de São Paulo, one of the scientists who discovered the new species, says that the discovery highlights two important aspects of modern biodiversity science: “That we still have much to discover and that there are too few researchers devoting themselves to this type of research.” De Carvalho says that fieldwork over the past decade has led to the discovery of 15 new species in this specific stingray family. He stresses: “We’re talking here of large stingrays, up to one metre wide. There are a mere 10 research groups working on the taxonomy and diversity of sharks and rays worldwide, even though much collecting and fieldwork is needed to understand the diversity of the group. Part of the challenge is remarkable genetic diversity: no two specimens, even those collected side by side and of the same gender, size, and species, are entirely alike. This great variation has to be properly understood before we can know the true diversity of the group.” Ecologically, because stingrays have internal fertilisation and reproduce slowly compared to many freshwater fishes, they are more easily threatened by environmental degradation or illegal harvesting by the aquarium industry. “They may be good indicators of general environmental health, as top predators usually are,” says de Carvalho. “And all that rests of the shoulders of good descriptive taxonomy and biodiversity science.” Quentin Wheeler is director of the International Institute for Species Exploration, Arizona State University Zoology Wildlife Marine life Animals Quentin Wheeler guardian.co.uk

Now other arrivals are beginning the process of establishing themselves Every day, shortly before noon, the holy men in saffron robes perform the same ceremony. Watched by scores of people sitting cross-legged on pristine marble floors, they bang small cymbals and wave candles while chanting incantations to statues of Hindu gods. Any visitor to their temple, one of the largest in the world, could not fail to be awed by the spectacle. But the Shri Swaminarayan Mandir is a temple built on superlatives. Everyone from Princess Diana to Jimmy Carter has paid a visit. On 27 October 2000 it broke a world record by serving 1,247 vegetarian dishes to mark the start of the Hindu new year. The temple, however, is not in Bengal or Kerala. It is in suburban north-west London, in Neasden, where it nestles incongruously near rows of Edwardian terraces. The site was chosen partly because of the region’s large number of Hindus, many of whom arrived from Uganda after being expelled by Idi Amin in the 1970s. As Yogesh Patel, a spokesman for the temple, acknowledges, the suburb was attractive to Hindu migrants because of “better employment prospects … the choice of good schools and business opportunities”. The temple, which has a highly successful independent school, is testimony to something significant happening in Britain, a shift that has been occurring largely without notice. Second- and third-generation migrant communities are on the move, driven by increasing affluence and aspiration. “We are seeing an emerging segment of dynamic young professionals, successful entrepreneurs and ambitious, resourceful wealth creators, all giving back to our country, enriching it economically, socially, culturally,” Patel said. Increasingly, younger generations believe their futures lie in the suburbs. The extent of this trend will emerge with greater clarity once the results of this year’s census are published. But an exhaustive analysis of Britain’s ethnic minorities, carried out for the Observer by Experian, the data-mining company, paints a vivid picture of the impact they are having on regions where once they were notably absent. Experian’s Mosaic database tracks almost 50 million people in Britain via their surnames. The names are then matched to postcodes, allowing the social mobility of immigrant groups to be tracked. “In the old days you would see these groups conspicuously settling in inner-city areas,” said Professor Richard Webber, who developed the database, “but you can now see how most groups have suburbanised themselves.” Experian’s data confirms the hypothesis. In London suburbs of the sort that are dominated by 1930s-built semi-detached housing, there can now be found high concentrations of Sri Lankans in the south (New Malden, Mitcham), Sikhs in the west (Southall, Hounslow), Hindu Indians in the north-west (Wembley, Harrow) and Greek Cypriots in the north (Southgate, Palmers Green). According to Webber, these are minority groups who have traditionally sought to acquire their own homes. As their economic circumstances have improved, they have moved outwards. Contrary to common stereotypes, the data suggests that many members of immigrant communities live in relatively prestigious neighbourhoods. Mosaic found that, if you live in the highest-status neighbourhoods, your chances of having a Jewish or Armenian name are five times the national average. Many other groups – notably Greek Cypriots, Iranians and Japanese – are also over-represented in these neighbourhoods. Almost one in four people in Harrow now have a Hindu Indian surname. By contrast, people of Pakistani and Bangladeshi origins are far more likely to live in poorer neighbourhoods, as are Albanians, black Africans and Vietnamese. The findings suggest that Britain is also becoming more diverse. The fastest growth has been among minorities who in 2006 were small in number, with the proportion of Slovakians rising by 977% and Lithuanians by 582%. There has also been rapid growth of black South Africans and Zimbabweans and of people from the former French west African colonies, such as Ivory Coast and Mali. The number of adults with Nigerian and Ghanaian names has doubled. By contrast, the growth in the number of adults from traditional centres of UK immigration, such as the West Indies, India and Pakistan, has been much lower. Some immigrant streams, from countries such as Vietnam, Laos and Mauritius, have almost ceased. Areas that have seen the greatest rise in the number of people with Mandarin Chinese names are around universities, reflecting the surge in students from mainland China. Over the same period, there was a 13.5% fall in the number of adults with Anglo-Saxon names living in smarter, private flats and a decline of 12.5% in the same group living in council flats. Conversely, there were increases in the proportion of people from eastern Europe and Africa and of the Hindu and Muslim religions in both types of housing. Tim Butler, professor of geography at King’s College London, and co-author with Chris Hamnett of Ethnicity, Class and Aspiration: Understanding London’s New East End , recently carried out studies in five regions in the east of the capital. “Among Asian groups, and particularly Indians, there was a desire to move out from inner London boroughs to outer London boroughs, particularly Redbridge. There were two main reasons for that: one was the attraction of suburban housing and the other was the high-quality schooling that met their aspirations. Many had been settled in the East End of London for possibly two to three generations and had themselves been to a local university and were keen for their children to get into one of the professions.” The trend has had some unusual consequences. New Malden in south London, with an adult population of 23,000, now has the largest expatriate community of South Koreans in Europe. Some estimates suggest that there are as many as 8,000 South Koreans living in the district, whose high street boasts at least 20 Korean businesses. Tesco has said it sells more fruit and vegetables in New Malden per head of population than anywhere else in Britain, and attributes this to local enthusiasm for healthy food. “When the embassy came over here [to nearby Wimbledon] in the 1970s, many followed suit,” said one South Korean shopkeeper. “They found houses in New Malden because suburban areas had cheaper properties and good travel opportunities into London. Gradually, their friends and families came over and gathered here.” But it was in the early 1990s that things really took off. “Many bankers and financiers came to New Malden, attracted to the area for the same reason,” the shopkeeper said. “Around 2,000 South Korean students came here because the education is very good.” A minister at the local Methodist church acknowledged that the presence of a large ethnic minority had created tensions. But, she said, the World Cup of 2002 had provided an unlikely opportunity for greater harmony. “South Korea was playing and there were massive celebrations. They were parading up and down the street, singing and shouting, everything. “But then, later on, in the early hours of the morning, they came down and cleaned the streets, even picking up the tiniest cigarette butt. And that so impressed the rest of the community. Not only do they celebrate politely, they clean up after themselves.” New Malden is also home to a large Sri Lankan community, with many working in local care homes. Almost 6% of New Malden’s population now has a Sri Lankan surname. The Methodist minister said while both groups were very different, they were united in their hopes for the next generation. “They put more effort into transforming their communities and enabling their children to aspire to the positions that they had in their home countries, but haven’t had here.” Admittedly the migrant aspiration to escape the inner city is nothing new. “Think about Brick Lane,” said Sarah Mulley, associate director of the IPPR thinktank. “You’ve had successive migrant groups moving into the inner city and then, when they are established, moving out to be replaced by another migrant group. You’ve had French Huguenots, Jews, Bangladeshis. They arrive and then disperse.” But changes to immigration policy suggest that the shift to more affluent suburbs will become more pronounced. “Restricted immigration regimes mean migrant workers entering the UK are more likely to be highly paid and highly skilled,” Mulley said. “People are now coming to do a specific, professional job, which means they are concentrated in particular areas that are increasingly outside London. The profiles of those communities are changing.” Immigration and asylum Jamie Doward guardian.co.uk
Continue reading …The actor created a theatre in Jenin but was killed for his ideals He had feared for his life in the past, but Juliano Mer-Khamis foresaw no danger when he carried his one-year-old son, Jay, to his old red Citroën for the drive home from the theatre he had founded in the West Bank city of Jenin. With his son on his lap and the nanny in the passenger seat, he pulled out and then braked when he heard his name called. Bullets smashed through the car window and Mer-Khamis moved his foot off the brake. The car moved slowly forward past a United Nations depot and a pool hall before scraping to a halt against a wall. The boy was untouched; the nanny suffered a cut to her hand. But Mer-Khamis was hit by seven bullets and died shortly afterwards. The Palestinian police announced on Wednesday that they had arrested a member of Hamas for Monday’s murder. Last week, as friends and supporters of the Freedom Theatre in Jenin, which Mer-Khamis ran, struggled to comprehend his death, mourners buried the 52-year-old actor next to his Jewish mother, Arna Mer, in a kibbutz in the north of Israel. Memorial meetings were held in Jenin and Haifa for a man who described himself as “100% Palestinian and 100% Jewish”. “He was aware of the danger and, although he joked about it, he was sometimes afraid,” said his partner, Jenny Nyman, who is pregnant with twins. “But he always said that he would rather die on his feet than live on his knees.” In Haifa, friends gathered at the Al-Midan Theatre, a state-funded Jewish-Arab theatre, where they delivered eulogies in Arabic and Hebrew to Mer-Khamis, who first appeared on film in the 1984 movie of John le Carré’s The Little Drummer Girl alongside Diane Keaton. He later became a major figure in Israeli cinema and theatre. But it will be for his efforts at the Freedom Theatre that Mer-Khamis will be mainly remembered. A project that grew out of his desire to offer artistic freedom to the youth of Jenin, it was also the resurrection of his mother’s theatre, a West Bank drama group to which she devoted much of her life. In her dying months, Mer-Khamis made a film, Arna’s Children , about her and her theatre – but in 2002, the building was destroyed during the second intifada. In 2006, with the help of Zakaria Zubeidi, a former Al-Aqsa Martyrs Brigade leader who had renounced violence and was given amnesty by Israel, Mer-Khamis reopened it. Speaking to the Observer last week, Nyman recalled the many difficulties Mer-Khamis had encountered in doing so. “People voiced their concerns, often politely but sometimes with firebombs,” she said. The theatre once staged an adaptation of George Orwell’s Animal Farm , which was perceived to label the Palestinian leadership as collaborators; the building was later petrol bombed. “We had support from sheikhs who led prayers on stage, but there is no doubt that, in an oppressed society like Jenin, there are always people that are afraid of change,” Nyman added. The Freedom Theatre brought change in all sorts of ways. Mer-Khamis found that encouraging girls to take part in productions was no easy task. “We had no problem attracting boys to the theatre,” said Nyman. “But girls were more difficult. We worked hard to make it acceptable. We visited families, invited them to the theatre and we got their consent.” Mer-Khamis, whose parents’ union – that of a Jewish woman with a Christian Arab man – symbolised their vision for the people of Israel and the Arab states, soon became a fixture in Jenin. “When we came in 2006 we were afraid, but we have had no problems for years. The theatre has become part of the society. Not fully accepted, but nothing is ever fully accepted here,” said Jonatan Stanczak, one of the founders of the theatre. Last week an old woman, sitting in the street metres from where Mer-Khamis was shot, kissed the tips of her fingers to emphasise her love for him. “He was wonderful, wonderful,” she said. As she spoke, a sombre procession of mourners, carrying portraits, flowers and Palestinian flags, walked from the centre of Jenin to its refugee camp and theatre. The residents of the camp watched the group of around 60 mourners without disrespect but with no great interest, either. Supporters in Israel and the West Bank are determined that Mer-Khamis’s dream should continue. Colleagues hope to stage an international theatre festival to allow supporters from around the world to show their appreciation. Nyman is looking to the future. “Jay knows that something is wrong. I’m glad that he won’t consciously remember what happened. Now I must take care of our son and give birth to our children and get us on the right track,” she said. “I’ll probably never live in Jenin again, but I feel very strongly that his work has to be carried on. I would hate for his death to have been for nothing.” Palestinian territories Israel Theatre Conal Urquhart guardian.co.uk

Continue reading …American ‘optimism expert’ who inspired prime minister fears that he got it all wrong As David Cameron’s £2m plan to measure the nation’s happiness gets under way this month, the American psychologist whose work inspired it has said he has changed his mind about the importance of being happy. One of the pioneers of positive psychology, Professor Martin Seligman insists he is not recanting the doctrine which has made him a bestselling author and world-renowned expert on optimism but just that we should be focusing less on people’s happiness and more on their ability to “flourish”. He said he was naive in the past to think wellbeing was based only on mood. “The word ‘happiness’ always bothered me, partly because it was scientifically unwieldy and meant a lot of different things to different people, and also because it’s subjective,” said Seligman, the director of the Positive Psychology Centre at the University of Pennsylvania. The prime minister has long been interested in Seligman’s work and first floated the idea of a “happiness index” in 2005. When he was in Downing Street Tony Blair considered the idea but dismissed it as “too flaky” and Cameron has been criticised for focusing on wellbeing as a distraction from the economy. He has admitted that measuring happiness could be seen as “woolly” and “impractical” but insists he wants a gross domestic happiness scale to become as reliable an indicator of a country’s progress as its economic output. Now the Office of National Statistics has four happiness questions in this year’s annual Integrated Household Survey which will be sent out to 200,000 British homes this month. Seligman, who has been in touch with the British government over his methods, said he welcomed the move on “both on scientific grounds and on political grounds”. But he added that the notion of what made people happy had to be rethought. He said he has become increasingly frustrated with the perception of what he called “happyology” and has written a new book called Flourish , which will be released in the UK next month. “I wanted to be much clearer that this was much more than a happyology. What humans want is not just happiness. They want justice, they want meaning. An interesting example is that there is quite a bit of evidence that says people’s mood isn’t as good once they have children. If that were all people were interested in, we should have been extinguished a long time ago,” he told Psychologies magazine in an interview to be published next week. Even depressed people, he said, can flourish. “I think you can be depressed and flourish, I think you can have cancer and flourish, I think you can be divorced and flourish. When we believed that happiness was only smiling and good mood, that wasn’t very good for people like me, people in the lower half of positive affectivity. “When positive emotion was more central to your ideas, one problem was the evidence that most people have a ‘set point’ or ‘set range’ for their mood, meaning that whatever they do or whatever happens to them, they tend to revert to a certain level of happiness.” It was while president of the American Psychological Association in 1998 that Seligman began to promote the idea that psychology should be about creating better mental health. He is involved in a project with the US Army to increase levels of resilience and decrease mental health problems among soldiers and there is enormous interest in what positive psychology could achieve in schools.
