Hope For a Truce 
  
 Even without that artificial nudge, nature appears to be turning a corner. After years of watching the cancer relentlessly take her beloved devils, Jones has seen some tentative signs of a truce between the devils and the tumor. Even in the hardest-hit areas, the devils haven’t disappeared entirely, the way Jones’ models predicted a decade ago. Populations have fallen by 90 percent, but no more than that, and Jones believes some of those surviving devils may be acquiring a kind of resistance. 
  
 Jones’ other source of hope, though tenuous, comes from a population of devils in the north-central part of the state, on the front lines of the cancer’s steady westward march. Devils in the west are somewhat genetically distinct from those in the east, where the disease began, and these western devils might be more resistant to the disease. 
  
 Jones herself is now far too busy orchestrating research projects to spend much time in the field. But her research assistant Rodrigo Hamede Ross has been studying this population since before the disease hit the area in 2006. On a November day I joined him at his study site near Cradle Mountain, one of Tasmania’s most popular national parks. Finding a devil in one of his traps, he repeats Jones’ dance from many years before, shaking it out into a burlap bag, sitting on the ground and placing it firmly between his legs. He blows on the devil’s nose and it opens its mouth. His assistant moves its tongue aside with a stick, and Hamede Ross peers inside its mouth. “Mara’s healthy,” he says of the 3-year-old mom, her teats full of milk. 
  
 When he started at this site, he braced himself for the decimation he’d seen in other parts of the island, knowing the disease would arrive soon. But by 2008, it was clear that something was different here. He occasionally found tumors on the animals in his traps, but it was rare. The population wasn’t crashing. Devils were still making it to old age. Then Hamede Ross saw something even more remarkable: In five devils, the tumors got smaller and went away. 
  
 He pricks Mara’s ear and squeezes out enough blood to fill a small vial. Murchison — sneaking in a field trip while home in Tasmania visiting family — watches over his shoulder. The vial may eventually come to her lab for sequencing, to help figure out what shields this population from the cancer decimating devils elsewhere. 
  
 A few traps after we leave Mara, Hamede Ross recognizes a 3-year-old male on sight: Bariloche. He isn’t so lucky. Bariloche first showed up in Hamede Ross’ traps with a tumor six months earlier, in May. Now, the tumor pushes out from his cheek. After examining him, Hamede Ross lets him go. “He hasn’t lost molars and canines, so he can still feed,” he says. “I’d guess he’ll still be around in February but not in May.” 
  
 Hamede Ross started seeing more sick animals like Bariloche in 2011, and testing of the tumors showed that a new, more virulent strain of the cancer had arrived. But his concern has been alleviated a bit since then. “It’s still pretty different from other places,” Hamede Ross says. Devil populations in the Cradle Mountain region have dropped only 35 to 40 percent, compared with 90 percent declines elsewhere. 
  
 Right now, there’s nothing the scientists can do to stop the spread of the cancer. They can only work to understand how it’s behaving and watch for an opportunity to intervene. “We’re trying to identify the mechanisms of evolution as it’s occurring in the wild” and translate it into a strategy to save the devils, Jones says. “Can we speed up the process to get coexistence?” 
  
 Sitting at her desk in Hobart, Jones isn’t as tan as in earlier pictures, and it’s been years since a devil has sniffed her sunscreen. But her mind is always on the devils that rely on her — along with the potoroos and bandicoots and pademelons that rely on them. For the first time in more than a decade, she feels a cautious hope for their future. “If you asked me five years ago,” she says, “I would have said that things look quite dire. If you ask me now, I feel quite optimistic ... but we’re not going to see recovery overnight. It may take 20 to 30 years.” Then her voice lowers as she considers the life raft. “And in the meantime, we don’t want to lose anything.”

 ALBUQUERQUE, N.M. — The Albuquerque BioPark Zoo is ramping up security with guards and surveillance cameras after a rare Tasmanian devil named Jasper was killed in his enclosure last week. 
  
 A reward of $5,000 also has been announced for information leading to the arrest of any individuals connected to Jasper’s death. 
  
 “The mayor has made it a top priority for our BioPark,” Mayor Richard Berry’s chief of staff Gilbert Montaño told the Journal. 
  
 Jasper was found dead Wednesday morning and police believe someone intentionally killed him with a chunk of asphalt. A veterinary exam concluded Jasper died from a fractured skull and brain trauma, and a piece of asphalt was found nearby. 
  
 As of Monday, police had not identified a suspect, Albuquerque police spokesman Tanner Tixier said. 
  
 The exact cause of the fracture has yet to be determined. Tissue samples were sent to a lab for testing, but it could take days or even weeks to be examined and results returned, according to a New Mexico BioPark Society news release. 
  
 There were no security cameras capturing footage of the enclosure where the Tasmanian devil was kept, but “there is surveillance video in that general area,” Tixier said. The investigation is ongoing and police are looking at footage of areas around the enclosure to try to identify people who might have witnessed the crime or committed it. 
  
 Montaño said more security guards are patrolling the zoo and more cameras will be installed around the grounds, although he declined to say how many of either is included in the new security plan. 
  
 Jasper was one of four Tasmanian devils – two males and two females – loaned to the Albuquerque BioPark Zoo as part of an effort to create a breeding program for the species that has been decimated by a form of cancer. The Tasmanian devils came to the zoo in December 2013 on loan from the Healesville Sanctuary in Australia. They are among only about 600 alive in captivity today, according to Zoo Director Rick Janser. 
  
 “We have worked long and hard to bring these wonderful creatures to the United States and to provide them with a top-notch environment,” Janser said. “To have this happen so soon after they arrived here has been very hard on the zoo staffers who work daily with these fascinating animals.” 
  
 Montaño said zoo officials have been in contact with officials from Australia, and the Mayor’s Office has not heard of any plans by Australian authorities to remove the other three Tasmanian devils from the zoo. 
  
 The New Mexico BioPark Society is offering $4,000 – in addition to a $1,000 reward from Crime Stoppers – for information leading to the arrest of any individuals involved in Jasper’s death, the society announced in a news release. 
  
 Police are asking for anyone who may have information about this case to call Crime Stoppers at 843-7867. |||||
More security cameras are in place, additional guards are on duty, and a $5,000 reward is being offered for anyone with info leading to an arrest in the killing of Jasper the Tasmanian devil, the Albuquerque Journal reports. Police think the rare marsupial—one of four brought to New Mexico's Albuquerque BioPark Zoo in December from Australia as part of a breeding initiative—was apparently killed with an asphalt chunk found near the scene. Jasper, whose body was discovered Wednesday morning, was said to have died from a bashed skull and brain trauma, according to a vet exam. There are only about 600 Tasmanian devils alive in captivity; the species has been ravaged by an aggressive cancer, Discover reports. "We have worked long and hard to bring these wonderful creatures to the United States and to provide them with a top-notch environment," the zoo's director tells the Journal. "To have this happen so soon after they arrived here has been very hard on the zoo staffers who work daily with these fascinating animals."
