Social network research may boost prairie dog conservation efforts, according to a recent study.

While using statistical tools to map social connections in prairie dogs, researchers from North Carolina State University uncovered relationships that escaped traditional observational techniques, shedding light on prairie dog communities that may help limit the spread of bubonic plague and guide future conservation efforts.

"Prairie dogs are increasingly rare and are subject to bubonic plague," Dr. Jennifer Verdolin, lead author of the study and an animal behavior researcher at National Evolutionary Synthesis Center (NESCent), said in a statement. "This work improves our understanding of the social dynamics within a prairie dog colony, which could help us find ways to mitigate the spread of plague. It also helps us understand how these social groups are connected, so we can limit the disruption to prairie dog populations when we need to relocate them for conservation purposes."

For the study, the researchers used data Verdolin collected on three Gunnison's prairie dog (Cynomys gunnisoni) colonies in Arizona, ranging in size from 60 to 200 individuals. Each colony is made up of numerous, smaller social groups that can consist of up to 15 individuals

Amanda Traud, co-author of the paper, developed statistical tools using social network theory to analyze one year's worth of data on the three colonies, focusing specifically on "greet kissing," in which prairie dogs briefly lock teeth with each other. If individuals are from the same social group, they part amicably. If they are from different groups, they usually fight or chase one another after greet kissing.

By looking at data on greet kissing, Traud established which prairie dogs were in the same group. These groups were consistent with the groups Verdolin had determined, using conventional observational methods of behavior and location.

However, the math-driven social network theory approach also identified substructures within those social groups and key "bridge" individuals that connected different groups -- findings that may have significant conservation applications.

"For example, there's a possibility that we could slow or stop the spread of plague in a colony by relocating these bridge individuals," Traud said.

Verdolin said conservationists could use this data to "be sure to relocate all of a relevant social group, rather than splitting up groups. That could improve the group's chances of thriving in a new environment."
