Seeing the world through ants | @theU – @theU

Ants are among the most numerous insects in the world, numbering from 10-100,000 trillion individuals globally with more than 10,000 species. But you dont have to tell that to John Jack Longino, professor of biology.

Known affectionately as Ant Man in the School of Biological Sciences at the University of Utah and beyond, Longino is part of a globe-spanning initiative called the Ants of the World Project that aims to generate the most complete phylogenetic tree of the ant family (Formicidae) to date.

Part of that project is Ant Course, a regularly occurring field course on ant biology and identification. After three years of accommodating the pandemic, this year the group, involving multiple research universities, is convening in Vietnam Aug. 1-13. During the course, the worlds ant identification experts get together to teach 24 students all about ants. Beginning in 2001, the course has been staged in the United States, Costa Rica, Venezuela, French Guiana, Peru, Uganda, Mozambique, Borneo and Australia.

These courses have become famous, says Longino, with generations of students being shaped and connected by their Ant Course experience. The Ants of the World project, he explains, integrates teaching and research. The initiative funds three new Ant Courses in locations that are poorly known, training new generations of ant biologists while they learn about the ants of these regions.

After a long delay due to COVID, we are finally offering our first Ant Course, in Vietnam, says Longino of their field site in Cc Phng National Park, just south of Hanoi. Im really looking forward to meeting this new group of students, interacting with Asian colleagues, and experiencing first-hand the ant fauna of Southeast Asia. Situated in the foothills of the northern Annamite Range, the national park consists of verdant karst mountains and lush valleys with an elevation that varies from 150 meters (500 feet) to 656 m (2,152 feet) at the summit of May Bac Mountain, or Silver Cloud Mountain.

Its all part of Ants of the World Projects attempt to survey nearly all ant genera and just under half the described species using advanced genome reduction techniques. The result will be a comprehensive evolutionary tree of ants, out to the smallest branch tips.

The resulting data set will help researchers answer questions: Are there predictable patterns of intercontinental dispersal and diversification? Following dispersal to a new region, is there accelerated filling of morphological and climate space? How have biotas responded to climate shifts in the past? Can we predict how ants will respond to the current rapid climate change?

Longino and Elaine Tan, a graduate student in the Longino lab, will be meeting up with 34 other ant specialists and ant specialists-to-be. Along with Ant Man, course faculty include the other principal investigators of the Ants of the World Project: Michael Branstetter (USDA-ARS), Bonnie Blaimer (Museum fr Naturkunde in Berlin, Germany), Brian Fisher (California Academy of Sciences) and Philip Ward (UC Davis).

While Ants of the World is a collaboration of four different institutions, including the School of Biological Sciences at the U, Ant Course is organized and run by the California Academy of Science and is designed for scholars to share information and discover together the ants of a particular region. It applies ant biology to established areas of inquiry but also encourages students to ask new questions.

Zahra Saifee is a University of Utah intern who will be accompanying the team as a scientific communications specialist. She says of Ant Course, it really is about the ants, what new species there are in [a particular region and] where species overlap. The team discusses their observations of what theyre doing with others across the world. The core is bringing diverse people to nerd out about it for two weeks.

A lot of the time in Vietnam, says Saifee, is set up just to explore and see what people will find. Curiosity is at a premium, bringing observations to the group as a sounding board. People can bring to the group rough drafts of research and ideas.

This open-door approach to discovery was transformative for Rodolfo Probst, Ph.D., a member of the Longino lab who successfully defended his dissertation just this month. His 2013 Ant Course experience in Borneo connected him to a years work back east following his graduation from college before he settled into graduate school as part of Longinos lab.

Ants are the focus of that labs research but its not just about ants. The research goals of the Longino lab involve reciprocal illumination, in which the latest evolutionary concepts of species formation, combined with the latest genetic tools, allow the construction of a detailed biodiversity map of ants. The patterns revealed in the map then inform general concepts of biological diversification.

The research has the additional benefit of allowing other researchers, like those students participating in Ant Course, to more easily identify ants. To this end, Longino helps curate a large online specimen and image database, a major resource for ant researchers worldwide.

To study the way ants network can potentially speak to the design and character of larger ecosystems, Saifee suggests, making the study of ants more than a niche science. It propels one to look at the larger picture of lifenot just its wonders, but its changes and adaptations. In short, its ecology and evolution. There are a lot of different species [of ants] and how we organize data is key to new scientific discoveries, concludes Saifee.

Making new discoveries about ants is important because, as subject models, they are on par with vertebrates and vascular plants as key taxa for ecology, evolutionary biology, biogeography, conservation biology and public interest. Having a solid phylogenetic history opens entire new worlds of biological exploration and has been achieved for vertebrates and many plants. With a little more effort, much of which is being addressed by the NSF-funded Ants of the World project, the same can be true for ants.

And Ant Course in Vietnam is currently at the center of that ambition.
