Oh, and seeing a pride of lions take down a puku later that night was pretty cool, too. Two safari jeeps filled with NAU faculty and students sat quietly and watched the circle of life.<\/p>\n
It wasn\u2019t the typical study abroad or research experience, perhaps, but it was the trip of a lifetime.<\/p>\n
Walker, along with School of Forestry professor Carol Chambers<\/strong>, led a group of students\u2014four undergraduates and grad student Dan Sanchez<\/strong>\u2014halfway around the world to experience what only Africa has to offer. They spent a week at Zikomo Safari Lodge near Mfuwe, outside South Luangwa National Park, exploring the park, doing non-invasive research on the wildlife and learning about Africa\u2019s conservation history and challenges. Thanks to an NAU grant, they also got to donate school supplies to local schoolchildren and help with an unusual two-pronged economic development program in the village.<\/p>\n For Walker, who studies wildlife from the DNA they leave behind, the program was a chance to introduce students to a place she loved and did research early in her career while also increasing passion for wildlife conservation and global bridge-building.<\/p>\n \u201cIt seems like Africa gets under your skin and you never get it out, and you want to go back,\u201d she said. \u201cFor me, it was really great to go back and bring a class that can experience Africa in terms of culture and wildlife. The wildlife is very much in need of protection, some species more than others. To see the elephants or the wild dogs or the leopards or lions in person, these charismatic megafauna, is a big deal, especially if you\u2019re into wildlife and their conservation.\u201d<\/p>\n Four students took the Wildlife Conservation and Management in Africa class, which Walker and Chambers co-taught; it culminated with their trip to Africa. The class met a few times throughout the spring semester, talking about the trip, their research and how to prepare, as well as writing papers and reading articles about conservation, wildlife management and poaching.<\/p>\n Then in June, they all boarded planes and flew halfway around the world, staying a couple of days in Lusaka, the capital of Zambia, before taking a short flight to Mfuwe, then driving to the lodge about an hour away.<\/p>\n Their days started early\u2014a 5 a.m. wake-up call, escorted to breakfast around a campfire at 5:30, then into the open-air jeeps for a wildlife game drive. They\u2019d get back to the camp around lunchtime, eat, then use the heat of the day for research or discussion or to go into the nearby village, see the school and visit with the residents. One day they went on a walking safari, allowing them the opportunity to see details like tracks, plants and feces up close\u2014or walking right up to a hyena, which they did, Walker said; the experience is very different on foot.<\/p>\n They returned to camp for tea\u2014it\u2019s all very English, Walker said\u2014then, as the sun began to set and the day cooled off, back into the jeeps for another drive. They ate dinner late and were escorted back to their chalets, where they stayed until the next morning. No one could be out when it was dark.<\/p>\n And that curfew was strictly enforced at the camp, Walker said. The hyenas, leopards, hippos and lions who walked through camp did a good job of keeping everyone inside.<\/p>\n \u201cA few nights later, when Dan and I missed the safari, a leopard came right by camp and we were unaware of it,\u201d she said. \u201cIt was pretty exciting for the students on safari, because they knew where camp was and the leopard was going right to it.\u201d<\/p>\n They had a couple of close encounters of the leopard kind. Tyler Tuengel<\/strong>, a senior forestry major from Glendale, said they saw a leopard hiding in the grasses one night and then lost it. Instead of looking through the tall grasses, Tuengel happened to glance up. The leopard was in a tree 15 feet in front of the jeep\u2014well within its jumping distance, if anyone\u2019s counting.<\/p>\n Another night, they caught a glimpse of a hunting leopard in the jeep\u2019s headlights.<\/p>\n \u201cThe guide flashes his light and you see him, and the next time he flashes you don\u2019t see him, and you\u2019re like, where\u2019d he go?\u201d Tuengel said. \u201cThe next thing you know, he\u2019s right at the side of the jeep.\u201d<\/p>\n For Katy Henry<\/strong>, a senior biology major from Phoenix, the program was a great experience to prepare her for graduate school and her eventual career in wildlife conservation. Helping with the research, collecting samples and seeing animals in their natural habitat, along with the effects of poaching, which remains the largest threat to big game animals in Africa, all contributed to the hands-on learning she wanted. It was such a good experience that she didn\u2019t even mind sharing a room with Alfonso, a wall spider the size of her hand.<\/p>\n \u201cIt\u2019s always been a dream of mine to go to Africa and see the wildlife there, but also, the research techniques that we used were really helpful, and learning how to use them will be good in the future,\u201d she said. \u201cI would like to do this as a career\u2014in Africa or anywhere. Africa would be really cool, but you can apply those techniques anywhere, so it was a good learning opportunity.\u201d<\/p>\n Walker, an assistant research professor in the School of Forestry<\/a> and the Pathogen and Microbiome Institute<\/a>, used this trip to collect data on DNA collected from animal feces. Sequencing the DNA in feces of wildlife tells scientists what the animals are eating, what diseases they\u2019re suffering from and even the basics of what animals are out there and how many of them there are. All of it helps conservation and population management.<\/p>\n That wasn\u2019t her big research question this time around. She had a new handheld genetic sequencer that reads DNA in real time in the field on a laptop\u2014a recent first for genetics research, which usually requires a laboratory and much larger machine. This device allowed Walker and Sanchez to sequence the DNA in Zambia to identify the species that wildlife were eating, meaning they only needed to bring the data home with her, which is much easier to get through customs than lion poop.<\/p>\n Her goal this trip was to determine how accurate this smaller device was and how feasible it is to use on crappy DNA at a remote field site on the other side of the planet, using diet of large carnivores as a test case\u2014a first for this technology. Before leaving Flagstaff, she and Sanchez tested it on fresh bobcat and jaguar feces, which Bearizona donated, while also using her lab-based sequencer, and got similar enough results that she trusted the portable sequencer. It still took some finagling to make it work, though.<\/p>\n See the online album for additional photos.<\/a><\/p>\n For instance, she didn\u2019t know the program needed an uninterrupted 2-minute Internet signal to start running, nor did she know there was a standalone version available with special permissions until she was in Zambia trying to run the sequencer. She used WhatsApp to ask her genetics research specialist in the United States to call the company in England to get the standalone product. (All of this was happening on Friday night.) No one was answering. They were camped out in the safari camp\u2019s office and the sun was going down and the rest of the group was on a night jeep ride when the sequencing finally started.<\/p>\n \u201cPretty soon it\u2019s 12:30 at night, we don\u2019t know if we can leave the computer or if Dan could take it to his room or if we had to stay up with it, and we were just watching the number of sequences grow until finally it\u2019s getting to a number where I\u2019m thinking, \u2018OK, we can actually publish,\u201d Walker said.<\/p>\n At about 1 a.m., as they were being escorted back to their chalets, having left the computer with a note to not turn it off, they heard the camp owner radio about a large hyena near her room. And the fun wasn\u2019t even done.<\/p>\n \u201cWe knew there was a hyena out there, and then we walk right by this hippo,\u201d she said. \u201cIt was just wild. We could hear the animals making sounds, the African night sounds, and then we walk by a giant hippo.\u201d<\/p>\n Hippos, hyenas and hunting leopards aside, the sequencer worked. It\u2019ll be returning to many more fields in the future.<\/p>\n \u201cIt was successful, although we learned a lot about what we need to do to make this really efficient,\u201d Walker said. \u201cWe\u2019ll be publishing that in the next couple of months.\u201d<\/p>\n Crystal Hepp<\/strong>, an assistant professor in the School of Informatics, Computing, and Cyber Security<\/a>, also went on the trip to study pathogens that mosquitoes carry. (Forget the lions. Mosquitoes are the most dangerous African animals.) She carried some interesting equipment: a 3-D printed attachment that held test tubes and attached to a cordless drill, which she used to turn captured mosquitoes into a slurry, from which she could extract DNA and RNA\u2014another process that used to happen solely in labs.<\/p>\n The extractions and reverse transcriptions worked, she said. Continued research on the data they pulled from the African mosquitoes will happen later this year.<\/p>\n Hepp also had an unexpected research accomplishment in Zambia. While explaining her research to one of the safari guides, he mentioned a local veterinarian who did surveillance for sleeping sickness, a disease carried by the tsetse fly. She met the veterinarian, who was Kalaluka Mbumwae, the lab director for the Kakumbi Tsetse and Trypanosomiasis Research Station, where they do all the tests for the country.<\/p>\n \u201cIt was mind-blowing that this well-equipped molecular laboratory existed in a rural Zambian village and that I just stumbled upon it through normal conversation,\u201d she said. \u201cI asked the lab director if I could take a few samples back with me to see if I could sequence full Tryponasoma brucei<\/em> genomes. He gave me five DNA extractions from infected cows and said, \u2018Let us see what you can do.\u2019\u201d<\/p>\n With those extractions, she and her research group are working on protocols to sequence T. brucei<\/em> genomes with the hope of understanding the circulation of the organism in rural Zambia, which will open up the possibility of collaboration with other researchers at NAU and in Zambia.<\/p>\n The lions came up more than once on the trip\u2019s highlight reel. So did the people they met.<\/p>\n \u201cI don\u2019t think I\u2019m ever going to forget the people,\u201d Henry said. \u201cThey were just amazing.\u201d<\/p>\n The groups got to do community outreach while there. NAU offers the Maxwell-Lutz Community Impact Award<\/a>, which provides funding to student teams doing an interdisciplinary project with a substantive community impact. Henry acted as the student leader, co-writing a proposal that highlighted the work they would do in Zambia and how it could improve the vitality of the local village, particularly for the schoolchildren.<\/p>\n With their $5,000 award, the team did three projects:<\/p>\n The poverty they witnessed in Mfuwe also was a new experience for the NAU students. That made their contributions that much more meaningful.<\/p>\n \u201cWhat sticks out the most is seeing the students. Our biggest goal was to help them out,\u201d Tuengel said. \u201cWhen we were in the United States, we felt like we didn\u2019t really bring a lot of supplies, but when we were actually there and put it on the table in front of them, we realized this was a lot of stuff.\u201d<\/p>\n \u201cOften we go to these beautiful places and we\u2019re taking\u2014taking photos, taking this experience,\u201d Walker said. \u201cIt was fantastic to actually be able to give back. That\u2019s what this award let us do.\u201d<\/p>\n The Maxwell-Lutz Award wasn\u2019t the only money moving the project forward. Between flights to Africa, which are expensive, and staying in a tourist lodge, even with the steep discount they got, the trip was expensive. While students paid most of their own way, two friends of NAU donated funds to help offset costs. Retired forestry professor David Patton<\/strong> and alumna Judy Wheatley<\/strong> had slightly different reasons for donating, but both described a love for NAU and the experiences they want students to have.<\/p>\n Patton, who retired about a decade ago, actually went to Zambia in the 1960s, to the very park this group was going. When Carol Chambers told him about their upcoming trip, he and his wife, Doris, pulled out photos and journals from their year living and working in South Luangwa National Park, describing what the country, which at the time was brand-new, was like. In addition to donating money, his daughter, who went to school in Zambia and just retired as a teacher in Phoenix, donated school supplies from her classroom.<\/p>\n \u201cDoris and I have three daughters, and we wanted them to work outside their environment,\u201d Patton said. \u201cMy interest with this program was to help students do something that they\u2019d like to do and otherwise wouldn\u2019t have a chance to do it.\u201d<\/p>\n Wheatley, a trustee for San Diego Zoo Global who graduated in 1970 with a degree in education, connected with Walker a few years ago through the owner of the Zikomo Safari Lodge, who collaborates with a wildlife conservation nonprofit called Nsefu. She started donating to Walker\u2019s Bat Ecology and Conservation Lab, and when she learned about this program, she wanted to help.<\/p>\n \u201cFaith shared her idea about the trip, and I saw it as a win-win, helping both my alma mater and Zikomo\/Nsefu,\u201d Wheatley said. \u201cSan Diego Zoo Global\u2019s vision is to lead the fight to end extinction, so this was an opportunity to walk the talk.\u201d<\/p>\n <\/p>\n Heidi Toth | NAU CommunicationsOpen-air classroom<\/strong><\/h3>\n
