ABSTRACT
When confronted with predators, many animals engage in lengthy, conspicuous displays. These antipredator signals are often assumed to be alarm calls that function to warn other individuals about the predator. However, recent research has shown that many of these anti-predator displays may actually be an attempt to communicate with the predator itself. Currently, little is known concerning the function and evolution of communication between two antagonistic parties, like predators and prey. This project will examine several hypotheses about the function of predator-prey communication by focusing on displays given by small mammals when they encounter rattlesnakes. The investigators will use video surveillance equipment and radio telemetry to document natural interactions between rattlesnakes and small mammals in the field. They will also design biorobotic animal models that can recreate key elements of the displays for experimental "playbacks". This playback approach will allow researchers to examine how specific behaviors used by small mammals may modify snake foraging behavior, and will provide the first experimental examination of key predictions derived from predator-prey communication theory. This project will provide novel insights into honesty in animal communication, antagonistic coevolution, and the role of receiver sensory systems in shaping signaling behavior. In terms of broader impacts beyond basic biological science, this project will (1) establish collaborations between ecologists and mechanical engineers to develop next-generation robotic technologies for the study of animal behavior; (2) increase participation of underrepresented minorities in research science; (3) develop public outreach through lectures, popular articles, radio, and documentary films; and, (4) provide mentoring for several undergraduate and graduate students.

The goal of our research was to understand the antipredator displays small mammals give toward venomous snakes. We completed five years of field and laboratory work pioneering a variety of observational and experimental approaches that had not been attempted previously. We studied both ground squirrels and kangaroo rats, different types of small mammals that independently have evolved anti-snake displays. We used a combination of biorobotic models, field videography techniques, animal observation, and other experimental approaches to develop and test different ideas concerning why these anti-snake signals have evolved. We published a large number of scientific papers that greatly transformed our knowledge of predator-prey communication. We now have a much better understanding of how these signals function, and what types of anti-predator adaptations have also evolved in these animals. Our research has led to a number of new discoveries that are currently serving as the foundation for more in-depth collaboration with other scientists. In addition to making these important scientific discoveries, we trained and mentored over 40 students (both graduate and undergraduate) who have gone on to productive careers in the sciences. We have also undertaken several different efforts to disseminate our results to the public, and stimulate further public interest in evolutionary research. These efforts include extensive interviews with different media outlets (print newspapers, online magazines, etc.). We have served as consultants on several nature documentaries featuring our research that have been viewed widely throughout the world. We have also developed and maintained several websites and a YouTube channel to disseminate results of our work to the public.
