BIOLOGICAL SCIENCES HIGHLIGHTS Jack Feminella, Department Chairman Auburn University Offers Students Intensive Study-Abroad and Research Opportunities in Costa Rica Auburn students interested in an intensive studyabroad program in one of the world’s most lush and adventure-filled locations can take advantage of the Organization for Tropical Studies, which owns and operates three biological field stations in Costa Rica: La Selva, Las Cruces, and Palo Verde. OTS is a non-profit consortium that includes 63 universities and research institutions from the U.S., Latin America, and Australia. Auburn University is the only school in the state that is a member of OTS, and since joining the consortium in 1987, Auburn students have had access to educational, research, and funding opportunities in Costa Rica that are not available to non-member institutions. Nicole Garrison, a doctoral student in the Department of Biological Sciences, spent time in January at the OTS field station La Selva, participating in the two-week Ecology and Evolution of Arachnids course taught by her major professor, Jason Bond, Auburn University OTS delegate. “It’s a really unique experience, and if you have any interest in field ecology and biology, it’s perfect,” said Garrison. “If you are unsure, you will know by the end of it if whether you are interested in a career that involves a lot of field work, because it is very intense. And you are out there in the thick of it with the ants, and the wasps, and the jaguars, and everything, so it’s a very enlightening experience.” Undergraduates can spend a semester abroad at any of the three stations studying topics such as: Global Health: Tropical Medicine and Public Health; Tropical Biology; or Tropical Biology on a Changing Planet. Graduate students have even more options, with anywhere from 12 to 15 courses being offered on a regular basis. “The biggest advantage to an Auburn student is participation in the OTS Tropical Biology and Tropical Ecology courses. I think any student that you talk to will tell you, it was a life-transforming experience,” said Bond. “It’s just a transformational experience to work in the tropics and to be in one of the most diverse habitats on the planet, and OTS is an amazing setting for that.” The three OTS-run field stations in Costa Rica offer logistics, lodging, meals, and necessary resources, such as classroom and research facilities, to students and faculty participating in courses or research. Additionally, because Auburn University is a member institution, students receive a discount to participate in OTS programs, and graduate students who participate become eligible to apply for OTS fellowships and grant funding. Over the last decade, more than $30,000 has been awarded to Auburn students by OTS. Garrison said a typical day began shortly after sunrise as participants gathered for breakfast. Following breakfast, they attended a morning lecture until lunch, and the afternoons were filled with field research. At 4 p.m., the group would gather again for a lecture, eat dinner, and then conduct more field research until late in the evening. “I think the class definitely opened up a lot more opportunities. Meeting the people in the class was a big step, because I feel like I really grew really close to them in two weeks because of the intensity of the experience and the one-on-one contact that I had with faculty members,” said Garrison. “So I feel like the communication with other people in the field, particularly with the ones from South America that I probably never would have encountered anywhere at a meeting up here, in Alabama, was really good, and it’s really interesting to get more of a perspective on the field from them.” In addition to Costa Rica, OTS recently initiated programs in South Africa where students have a choice to study either African Ecology and Conservation or Global Health Issues in South Africa.

In the last several years, he has discovered 36 new species of trapdoor spider, including one he discovered in Auburn and named Myrmekiaphila tigris. Millipedes were among the first terrestrial animals, dating as far back as 400 million years ago. Among the ancient group of species, about 20,000 have been described, and according to Jason Bond, professor of biological sciences and director of the Auburn University Museum of Natural History, there are potentially many more undiscovered species of millipede waiting to be identified. Bond specializes in in the evolution, systematics, and taxonomy of arachnids and myriapods, and he recently received a three-year, $548,000 grant from the National Science Foundation’s Division of Environmental Biology for his research proposal, “Millipede Systematics: Developing phylogenomic, classification, and taxonomic resources for the future.” The grant funding allows Bond to conduct research on millipedes that are in the arthropod class Diplopoda, a species that is distributed worldwide in nearly every biome. Despite their ecological importance as decomposers in forests, wealth of diversity with an estimated 20,000 to 80,000 species, and prominence as chemical warriors owing to their vast array of defense secretions, the group is woefully understudied. Bond and his team are working to revise the current ordinal and family-level classification systems using a modern phylogenomic framework based on next-generation sequence data and then hope to employ these data to explore the evolution of chemical defense secretions and their precursors. This past summer, Bond travelled to Costa Rica to the Organization for Tropical Studies Field Station in La Selva, where he collected millipede specimens for his research. “We surprisingly know very little about millipedes, such as how the various groups are related, why they produce defensive secretions, and the chemicals they produce; and it is still an open question as to why they secrete defensive chemicals at all. Was it for encounters of molds and microbes in the soil? Or, was it a defense against invertebrate predators? Did it evolve once or independently? And then there are some basics we do not understand, like we do not have a good taxonomic key to the families,” said Bond. “Millipedes are He is also conducting studies into orb spiders, focusing on evolutionary history, silk production, and webs. hard to tell apart, and there are not a lot of people working on them.” Bond also recently traveled to southern Africa and spent time in the Namib Desert studying a species of beetle, onymacris. “They live on the dunes in the Namib Desert, which is a very arid and dry environment. They have a mechanism to collect water called ‘fog basking,’” explained Bond. “When the fog rolls in off the south Atlantic to dunes, they run out and essentially bask in the fog and collect water droplets on their body surface. It’s a group of beetle “We have made some exciting discoveries about when and how orb webs evolved,” said Bond. “Since the early 1980s, scientists believed the orb web spiders shared the same evolutionary history. We discovered that is not the case. Now we know that the spiders that build orb webs do not all share a common ancestor and the orb web developed much earlier in spider history than we previously thought.” When Bond reflects on what drew him to study spiders, he notes the remarkable diversity of the animals and their ability to produce silk. “Spider silk has properties like extensibility and tensile strength that are on par with materials like Kevlar® and steel, yet spiders are able to produce these, as proteins, naturally,” said Bond. “My early interests were on the evolution of spider silk production but quickly expanded to studying spider diversity. Spiders are an incredibly diverse group with more than 42,000 described species that are found in almost every terrestrial ecosystem. And they or their close relatives have been around since the Devonian, which was more than 400 million years ago.” Bond has two master’s students and four doctoral students currently working with him in his lab.
