Scientists at Chicago’s Field Museum and New York’s American Museum of Natural History have discovered three new species of yellow-shouldered bats, genus Sturnira, in the Neotropics. On Wednesday open-access journal ZooKeys published their paper on two of the new species, Sturnira bakeri and Sturnira burtonlimi. The two new species were previously confused with S. ludovici, and S. lilium and S. luisi, respectively. With the discovery, genus Sturnira now has the most species of any genus in family Phyllostomidae, the leaf-nosed bats.

Species S. bakeri was named after Dr. Robert J. Baker, who “has made enormous contributions to our [Authors of the ZooKey paper] understanding of bats, particularly to the evolution of Neotropical phyllostomids”; and S. burtonlimi after Dr. Burton K. Lim, who “collected the type series of this species and has made many other important collections throughout the Neotropics and beyond”, the authors noted in the paper.

Within the New World tropics, the distribution range of the genus, the new species’ known living areas are in Costa Rica and Panama for S. burtonlimi, and Western Ecuador for S. bakeri. The researchers identified differences between different specimens, including those in their teeth, skull shapes, and DNA sequences.

Wikinews interviewed one of the chiropterologists, Paúl M. Velazco of the American Museum of Natural History, about the study.

((Wikinews)) The Sturnira genus now has 22 species, over 1.5 times larger than it was a year ago (14 species). Who contributed to this change? Did you participate throughout the entire process, or only the discovery of the last 2 species?

Paúl M. Velazco: The last Mammal Species of the World (Simmons, 2005) recognized 14 species for Sturnira. Since then three new species have been described [S. sorianoi Sánchez-Hernández et al., 2005; S. koopmanhilli McCarthy et al., 2006; and S. perla Jarrín-V. and Kunz, 2011] and one subspecies was elevated to the species level (S. hondurensis) by Gardner (2008). This brought the number of species of Sturnira to 18 by 2011. Along with my coauthor Bruce Patterson, we generated the most comprehensive phylogeny of the genus. For this we sequenced two nuclear and three mitochondrial genes from the liver or muscle tissue that had been frozen or preserved from each bat specimen, isolating nearly 5,000 base pairs of DNA. These sequences were obtained from specimens we have collected in the past (38) and from tissues we borrowed from different natural history collections. We published this phylogeny last year in the journal Molecular Phylogenetics and Evolution. Results of this study found that two subspecies of Sturnira lilium should be recognized as valid species (S. parvidens and S. paulsoni). Additionally we found three new species, two of them described in the ZooKeys paper. The third one hopefully will be published later this year.

((WN)) The genus is called Sturnira Gray in the paper. I’ve not seen extra adjectives in genus names, before. What is the context for such name?

PMV: Usually in papers that deal with taxonomy and nomenclature, the first time that a genus or species is mentioned in text is accompanied by the authority that describes that taxon. In the case of Sturnira, it was Gray in 1842 that named the genus.

((WN)) What caused your initial interest in the question in the genus? When did you become interested?

PMV: I have been studying bats for the past eighteen years and I am especially interested in the family Phyllostomidae that is endemic to the Neotropics. This family includes more than 160 species. It is the most diverse family of bats in the Neotropics, which together exhibits more variation in morphological features and feeding ecology than any other family-level group of mammals. Phyllostomid bats exploit an unusually diverse array of feeding habits including sanguivory, insectivory, carnivory, omnivory, nectarivory, pollennivory, and frugivory. Because of all mentioned before, phyllostomids are a really interesting group to work with. Sturnira and Platyrrhinus are members of this family.

((WN)) The paper mentions that the genus is now the most speciose genus in the Neotropical family Phyllostomidae. What genus did it beat? How many species does it include?

PMV: The other genus with the most species in the family is Platyrrhinus. Currently, it has 20 species, but soon it will increase to 21. Along with another colleague, Burton Lim, we have a paper in press describing a new species based on molecular and morphological data from the Guianan Shield.

((WN)) What equipment did you use?

PMV: For the ZooKeys paper, we examined several specimens under the stereoscope. The molecular phylogeny gave us the separation between species, from there our job was to focus on finding morphological differences between these groups.

((WN)) Did you conduct field study to identify the species’ habits? If so, where and how did you do that?

PMV: I have done fieldwork in Belize and Peru, and my coauthor did field work in Brazil, Ecuador, and Peru, where we collected several specimens of Sturnira (including the third species that has not been described yet). But the two species that were described in the ZooKeys paper are based on specimens collected by our colleagues Dr. Robert Baker from Texas Tech University and Dr. Burton Lim from the Royal Ontario Museum.

((WN)) How do you isolate of the living area of the new species from the living area of the old species?

PMV: We used the phylogeny of Velazco and Patterson 2013 (Molecular Phylogenetics and Evolution) as a framework for this.

((WN)) How long did the study take? What has been the most time-consuming activity?

PMV: It took almost a year. The most time consuming part was spending several hours behind the stereoscope looking for the diagnostic characters.

((WN)) Who participated in the study? What were their roles?

PMV: Dr. Bruce Patterson from the [American] Museum of Natural History and I. I was the one in charge of finding the diagnostic characters and together we both worked on the manuscript.

((WN)) Who do you collaborate with internationally about your study?

PMV: For this study I collaborated directly with Dr. Bruce Patterson from the Field Museum of Natural History, but studies like this cannot be completed without the contribution of scientific collections. We used specimens from the American Museum of Natural History, Carnegie Museum of Natural History, Louisiana State University, Museum of Southwestern Biology, Museo de Historia Natural de la Universidad Nacional de San Marcos, Museo de Zoología of the Pontificia Universidad Católica del Ecuador, Museum of Vertebrate Zoology at Berkeley, Royal Ontario Museum, Texas Tech University, and the National Museum of Natural History.

((WN)) What future research do you plan?

PMV: To keep doing what I love, which is going to the field, working at collections, and collaborating with the wonderful collaborators I have, all of this is an effort to try to understand bat diversity and evolution in the Neotropics, especially why phyllostomid bats are so successful at this. There is still much to discover, and hopefully we could, in time, implement conservation actions for species that have small distributions.

The possibility of large-scale protests in the face of the 3,000 journalists covering the Melbourne 2006 Commonwealth Games, has event organisers and the Government worried.

The group “Black GST” – which represents Indigenous Genocide, Sovereignty and Treaty – are planning demonstrations at prominent Games events unless the Government agrees to a range of demands including an end to Aboriginal genocide, Aboriginal Sovereignty and the signing of a treaty.

The Black GST say they hope the focus of the world’s media will draw attention to the plight of indigenous Australians during the Games. Organisers say supporters are converging from across Australia and from overseas. Organisers say up to 20,000 people may take part in talks, rallies, colourful protests and many cultural festivities designed to pressure the Federal Government on Indigeneous rights issues. They want the Government to provide a temporary campsite for the supporters, saying “organised chaos was better than disorganised chaos.”

The 2006 Stolenwealth Games convergence, described by organisers as the “cultural festival of the 2006 Commonwealth Games,” was virtually opened on March 2nd with the launch of the official “Stolenwealth Games” website. Scoop Independent News and Perth Indymedia reported that the launch was held at Federation Square in Melbourne. The site contents were projected via wireless laptop by the Stolenwealth Games General Manager, and a tour of the website was given on the big screen. He said “overwhelming amusement was the response from the audience.” The group say permanent access points to the website are being set up at public internet facilities across Victoria during the coming weeks.

“Interest in the Stolenwealth Games is building all over the world and this fresh, exciting and contemporary site will draw in people from Stolenwealth Nations around the globe to find out about the latest news and events,” said a Stolenwealth Games spokesperson. “We have been getting many requests from around the world wanting to know about the Stolenwealth Games. We have provided many ways that individuals and organisations can support the campaign by spreading the word.”

The Victorian Traditional Owner Land Justice Group (VTOLJG) which represents the first nation groups of Victoria, has announced its support to boycott the 2006 Commonwealth Games until the Government “recognises Traditional Owner rights.” The group asserts that culture has been misappropriated in preparation for the Games.

Organisers of the campaign say they welcome the formal support from the Traditional Owners. “While some seek to divide and discredit Indigenous Australia, this support is further evidence that the Aboriginal people are united in opposition to the ongoing criminal genocide that is being perpetrated against the Aboriginal people” said Black GST supporter and Aboriginal Elder, Robbie Thorpe.

“We now have endorsement from the VTOLJG and the Aboriginal Tent Embassy for the aims and objectives of the Campaign and we are looking forward to hosting all indigenous and non-indigenous supporters from across Australia in March,” he said. The Black GST group have said “the convergence will be held as a peaceful, family-focussed demonstration against genocide, and for the restoration of sovereignty and the negotiations towards a Treaty.”

But the campaign has received flak in mainstream media, such as Melbourne’s Herald Sun, who wrote: “the proposal to allow BlackGST to set up an Aboriginal tent embassy at a site well away from the Commonwealth Games will be interpreted by some as the State Government caving in to a radical protest group. A major concern for the Government… is to protect the event from disruption… no chances should be taken…”

The Black GST has been planning the convergence for months, calling for Aboriginal people and their supporters to converge on Melbourne. The Melbourne-based Indigenous rights group have called on thousands of people concerned about the plight of indigenous Australians to converge on Melbourne during the Games, which they have dubbed “the Stolenwealth Games”. But the choice of Kings Domain has made conflict almost inevitable, as the area is one of the areas gazetted by the State Government as a “Games management zone”.

Under the Commonwealth Games Arrangements Act, any area gazetted as a management zone is subject to a range of specific laws – including bans on protesting, creating a disturbance and other activities. The protest bans will be in effect at different times and places, and offenders can be arrested. A spokeswoman for the Black GST, which advocates peaceful protest, said the site had been chosen because it was close to where the Queen will stay on March 15. “We figured that she is only in Melbourne for 27 hours or something like that so we thought we would make it easy for her to come next door and see us,” she said. “We are a very open, welcoming group, so she will be welcome to come and join us.”

Kings Domain is the burial site for 38 indigenous forefathers of Victoria. Black GST elder, Targan, said trade union groups have offered to install infrastructure at the site. The group initially worked with the State Government to find a suitable camp site, but the relationship broke down when the Government failed to meet a deadline imposed by the protesters. “While we are disappointed the ministers were not able to meet deadline on our request, we thank them for their constructive approach towards negotiations and the open-door policy exercised,” said Targan.

A spokesman for Games Minister Justin Madden said the Government was still investigating other sites. Victoria Police Games security commander Brendan Bannan said he was not convinced the Black GST represented the views of most indigenous people. “We are dealing with the Aboriginal community and they don’t seem to support it at all … the wider Aboriginal community don’t support disruption to the Games at all,” he said.

The Government was told that Black GST supporters would camp in Fitzroy Gardens and other city parks should it fail to nominate a site. A spokesman for Aboriginal Affairs Minister Gavan Jennings said the Government was taking the issue seriously, but had not been able to finalise a campsite before the deadline.

Under special Games laws, people protesting or causing a disturbance in “Games management zones” can be arrested and fined. While prominent public spaces such as Federation Square, Birrarung Marr, Albert Park and the Alexandra Gardens fall under the legislation, such tough anti-protest laws cannot be enforced in the nearby Fitzroy Gardens.

Games chairman Ron Walker has urged the group to choose another date for its protest march through the city, which is currently planned to coincide with the opening ceremony on March 15. The group believes that an opportunity to gain attention for indigenous issues was lost at the Sydney Olympics and has vowed to make a highly visible presence at the Games.

The Black GST said the Australian Aboriginal Tent Embassy’s sacred flame, burning over many years at the Canberra site will be carried to Melbourne before the Games, and its arrival would mark the opening of the protest camp from where a march will proceed to the MCG before the Opening Ceremony.

Black GST claims supporters from all over Australia, including three busloads from the West Australian Land Council, will gather in Melbourne during the Games for peaceful protests.

Aboriginal Affairs Minister Gavin Jennings had offered Victoria Park to the protesters. Victoria Park, former home of Collingwood Football Club, where one of the strongest statements of Aboriginal pride, when St Kilda star Nicky Winmar in 1993 raised his jumper and pointed to his bare chest after racial taunts from the Collingwood crowd.

Black GST, which has labelled the Games the Stolenwealth Games, said the State Government had failed to find a suitable venue. Black GST may encourage protesters to camp in prominent parks such as Fitzroy Gardens and Treasury Gardens. Graffiti supporting the action has also appeared in central Melbourne.

Melbourne City councillor Fraser Brindley has offered his home to the Black GST organisers. “I offered my home up to people who are organising visitors to come to the Games,” he said. Cr Brindley will be overseas when the Commonwealth Games are held and has offered the free accommodation at his flat at Parkville. He said he agreed with the protesters’ view that treaties needed to be signed with indigenous Australians. “I’m offering it up to the indigenous people who are coming to remind Her Majesty that her Empire took this land from them,” said Cr Brindlley. Nationals leader Peter Ryan said: “This extremist group has no part in the Australian community.” Melbourne councillor Peter Clarke said the actions were embarrassing and that he would try to discourage him. “It’s not in the spirit of the Games,” he said.

Aboriginal elder, Targan, said the possibility of securing Victoria Park was delightfully ironic. “There’s a lot of irony going on,” Targan, 53, a PhD student at Melbourne University, said. “GST stands for Genocide, Sovereignty and Treaty. We want the genocide of our people to stop; we want some sovereignty over traditional land, certainly how it is used, and we want a treaty with the government,” Targan said.

A team of eight transplant surgeons in Cleveland Clinic in Ohio, USA, led by reconstructive surgeon Dr. Maria Siemionow, age 58, have successfully performed the first almost total face transplant in the US, and the fourth globally, on a woman so horribly disfigured due to trauma, that cost her an eye. Two weeks ago Dr. Siemionow, in a 23-hour marathon surgery, replaced 80 percent of her face, by transplanting or grafting bone, nerve, blood vessels, muscles and skin harvested from a female donor’s cadaver.

The Clinic surgeons, in Wednesday’s news conference, described the details of the transplant but upon request, the team did not publish her name, age and cause of injury nor the donor’s identity. The patient’s family desired the reason for her transplant to remain confidential. The Los Angeles Times reported that the patient “had no upper jaw, nose, cheeks or lower eyelids and was unable to eat, talk, smile, smell or breathe on her own.” The clinic’s dermatology and plastic surgery chair, Francis Papay, described the nine hours phase of the procedure: “We transferred the skin, all the facial muscles in the upper face and mid-face, the upper lip, all of the nose, most of the sinuses around the nose, the upper jaw including the teeth, the facial nerve.” Thereafter, another team spent three hours sewing the woman’s blood vessels to that of the donor’s face to restore blood circulation, making the graft a success.

The New York Times reported that “three partial face transplants have been performed since 2005, two in France and one in China, all using facial tissue from a dead donor with permission from their families.” “Only the forehead, upper eyelids, lower lip, lower teeth and jaw are hers, the rest of her face comes from a cadaver; she could not eat on her own or breathe without a hole in her windpipe. About 77 square inches of tissue were transplanted from the donor,” it further described the details of the medical marvel. The patient, however, must take lifetime immunosuppressive drugs, also called antirejection drugs, which do not guarantee success. The transplant team said that in case of failure, it would replace the part with a skin graft taken from her own body.

Dr. Bohdan Pomahac, a Brigham and Women’s Hospital surgeon praised the recent medical development. “There are patients who can benefit tremendously from this. It’s great that it happened,” he said.

Leading bioethicist Arthur Caplan of the University of Pennsylvania withheld judgment on the Cleveland transplant amid grave concerns on the post-operation results. “The biggest ethical problem is dealing with failure — if your face rejects. It would be a living hell. If your face is falling off and you can’t eat and you can’t breathe and you’re suffering in a terrible manner that can’t be reversed, you need to put on the table assistance in dying. There are patients who can benefit tremendously from this. It’s great that it happened,” he said.

Dr Alex Clarke, of the Royal Free Hospital had praised the Clinic for its contribution to medicine. “It is a real step forward for people who have severe disfigurement and this operation has been done by a team who have really prepared and worked towards this for a number of years. These transplants have proven that the technical difficulties can be overcome and psychologically the patients are doing well. They have all have reacted positively and have begun to do things they were not able to before. All the things people thought were barriers to this kind of operations have been overcome,” she said.

The first partial face transplant surgery on a living human was performed on Isabelle Dinoire on November 27 2005, when she was 38, by Professor Bernard Devauchelle, assisted by Professor Jean-Michel Dubernard in Amiens, France. Her Labrador dog mauled her in May 2005. A triangle of face tissue including the nose and mouth was taken from a brain-dead female donor and grafted onto the patient. Scientists elsewhere have performed scalp and ear transplants. However, the claim is the first for a mouth and nose transplant. Experts say the mouth and nose are the most difficult parts of the face to transplant.

In 2004, the same Cleveland Clinic, became the first institution to approve this surgery and test it on cadavers. In October 2006, surgeon Peter Butler at London‘s Royal Free Hospital in the UK was given permission by the NHS ethics board to carry out a full face transplant. His team will select four adult patients (children cannot be selected due to concerns over consent), with operations being carried out at six month intervals. In March 2008, the treatment of 30-year-old neurofibromatosis victim Pascal Coler of France ended after having received what his doctors call the worlds first successful full face transplant.

Ethical concerns, psychological impact, problems relating to immunosuppression and consequences of technical failure have prevented teams from performing face transplant operations in the past, even though it has been technically possible to carry out such procedures for years.

Mr Iain Hutchison, of Barts and the London Hospital, warned of several problems with face transplants, such as blood vessels in the donated tissue clotting and immunosuppressants failing or increasing the patient’s risk of cancer. He also pointed out ethical issues with the fact that the procedure requires a “beating heart donor”. The transplant is carried out while the donor is brain dead, but still alive by use of a ventilator.

According to Stephen Wigmore, chair of British Transplantation Society’s ethics committee, it is unknown to what extent facial expressions will function in the long term. He said that it is not certain whether a patient could be left worse off in the case of a face transplant failing.

Mr Michael Earley, a member of the Royal College of Surgeon‘s facial transplantation working party, commented that if successful, the transplant would be “a major breakthrough in facial reconstruction” and “a major step forward for the facially disfigured.”

In Wednesday’s conference, Siemionow said “we know that there are so many patients there in their homes where they are hiding from society because they are afraid to walk to the grocery stores, they are afraid to go the the street.” “Our patient was called names and was humiliated. We very much hope that for this very special group of patients there is a hope that someday they will be able to go comfortably from their houses and enjoy the things we take for granted,” she added.

In response to the medical breakthrough, a British medical group led by Royal Free Hospital’s lead surgeon Dr Peter Butler, said they will finish the world’s first full face transplant within a year. “We hope to make an announcement about a full-face operation in the next 12 months. This latest operation shows how facial transplantation can help a particular group of the most severely facially injured people. These are people who would otherwise live a terrible twilight life, shut away from public gaze,” he said.

Due to the damage by Hurricane Katrina and subsequent flooding, a number of colleges and universities in the New Orleans metropolitan area will not be able to hold classes for the fall 2005 semester. It is estimated that 75,000 to 100,000 students have been displaced. [1]. In response, institutions across the United States and Canada are offering late registration for displaced students so that their academic progress is not unduly delayed. Some are offering free or reduced admission to displaced students. At some universities, especially state universities, this offer is limited to residents of the area.

Under fire for illegal political and financial wrongdoing, Oral Roberts University president Richard Roberts stepped down from his position and Billy Joe Daugherty was named acting-president. Richard and his wife, Lindsay Roberts, are also members of the ORU Board of Regents, and it is not mentioned if Richard and/or Lindsay stepped down from the board.

On October 12 the plaintiffs of the original lawsuit amended it adding the university’s Board of Regents, which includes George Pearsons, Kenneth Copeland, Creflo Dollar, Michael A. Hammer, John Hagee, Marilyn Hickey, Oral Roberts, Lindsay Roberts, Richard Roberts, Jerry Savelle and Charles Watson to the suit. ORU Board member Kenneth Copeland was Oral Roberts airplane pilot in the 1960s, and current Board chairman, George Pearsons, is married to Copeland’s oldest daughter.

The plaintiffs cited that three days after the original lawsuit was filed, Roberts fired the university’s financial comptroller (who had been employed by ORU for 26 years) and “witnesses have reported voluminous materials and documents were shredded and destroyed, constituting spoilation of evidence.” The lawsuit argued that the Regents were a party to the suit due to negligence in failing to handle the issue as well as allowed a convicted child molester “mentor” students.

Also ORU recently admitted to the press that the IRS had warned ORU against the illegal nature of ORU’s political activity. That political campaign is what the plaintiffs alleged caused the wrongful dismissal of Tim Brooker. While the university declined to offer the IRS’ letters, a spokes-person confirmed the IRS sent two letters in 2006 about the political involvement.

A 54-year-old German farmer who lost both arms in a farming accident six years ago has become the first patient to receive a complete double arm transplant. The patient, whose name has not been released, underwent the operation at the Klinikum rechts der Isar, part of the Technical University of Munich (Technische Universität München), last week; he is said to be recovering well.

The operation lasted 15 hours and was performed by a team of 40 specialists in Plastic Surgery, Hand Surgery, Orthopedics and Anesthesiology, under the direction of the head of the Plastics and Hand Surgery department, Prof. Hans-Günther Machens, Dr. Christoph Höhnke (Head of Transplants, Senior Physician; Plastics and Hand Surgery) and Prof. Edgar Biemer, the former Chief of Plastic Surgery at the Clinic.

In a press statement released by the clinic, it was revealed that the patient had been thoroughly physically checked and had psychological counselling prior to the surgery to ensure he was mentally stable enough to cope with the procedure. Since completion of the surgery, the patient has been on immuno-suppressant drugs to prevent rejection of the new limbs.

Following the surgery, the press release from the clinic’s press manager, Dr. Tanja Schmidhofer, included the following statement:

Without the immuno-suppressant drugs given to the patient, the risk of there being a Graft-versus-Host Reaction or GvHR, would have been significant due to the upper arm containing a large amount of bone marrow, consisting of ICC’s or Immuno-Competent Cells, which would have triggered a near total rejection of the new limbs. A GvHR is a condition which results in the cells from the transplant attacking the immune system of the body.

Indications from the clinic suggest that the double attachment went well, although it could be up to 2 full years before the patient is able to move the arms.

The donor arms came from an unnamed teenager, who is believed to have died in a car accident.

Six teenagers were killed in a horrific road accident near Mildura in north-western Victoria, Australia late at night on February 18.

Cassandra Manners, aged 16, Stevie-Lee Weight, 15, Cory Dowling, 16, Shane Hirst, 16, and his sister, Abby Hirst, 17, died at the scene. Josephine Calvi, 16, was flown to the Royal Adelaide Hospital, where she later died of head injuries. Seven other teenagers were injured, including 15-year-old Marco Medici who is now in a stable but critical condition in The Alfred Hospital in Melbourne.

The accident occurred after the teenagers left a 16th birthday party and walked along Myall Road, Cardross, south-east of Mildura. A car allegedly came speeding around a bend, hit the gravel on the side of the road, lost control and struck the group. The alleged driver, later identified as 34-year-old Thomas Graham Towle, fled the scene on foot, leaving his 10-year-old daughter and four-year-old son in the car. Towle was later arrested by police in Redcliffs. He was taken to Mildura police station for questioning.

Towle has been charged with six charges of culpable driving causing death, four charges of negligently causing serious injury, one charge of failing to stop and one charge of failing to render assistance after an accident. Towle faced Mildura Magistrates’ Court on February 20. Magistrate John Dugdale remanded him into custody to reappear before the court on June 26.

Meanwhile, the town of Mildura and surrounding areas is in deep mourning. Premier Steve Bracks said the State Government will provide $AU40,000 for counselling and support services.

Around 3,000 people attended the funeral for Josephine Calvi today. Funeral services for the other five teenagers were held last week.
