Dr. Hobson received her PhD from New Mexico State University and was awarded two independent postdoctoral fellowships, the first at NIMBioS (the National Institute for Mathematical and Biological Synthesis) and the second at the Santa Fe Institute. She started her lab at the University of Cincinnati in Fall 2019 and is currently an Assistant Professor.

Abstract:
In many social species individuals create their social worlds through interaction decisions and are then subject to and constrained by these social constructs, which can affect an individual’s future actions. Understanding how much individuals “know” about their social worlds is critical in understanding these potential feedbacks. However, it is difficult to determine how much information individuals have about the social structures in which they live. In this talk, I summarize several ways my group is addressing these questions by combining empirical experiments with computational approaches to provide insight into cognition through social decisions. I highlight new work on parakeet aggression and dominance hierarchies to illustrate this approach. I show evidence that parakeet rank is unlikely due to individual characteristics and that group-level social dominance patterns can be plastic and can respond to group membership changes. Finally, I show how parallel or related experiments can allow for comparative analyses across species. These approaches, and a taxonomically broad perspective, provide new opportunities to investigate the effect of social information on individual behavior within conflict, and has the potential to provide rigorous evidence for the evolutionary patterns underlying social cognition.

Dr. Brian Barnes

Bio:
Dr. Barnes is currently a Professor of Zoophysiology with the Institute of Arctic Biology at the University of Alaska in Fairbanks. He's also the Director of Alaska INBRE, an NIH capacity building program in biomedical research and also the Science co-Director at Toolik Field Station. He participated in summer workshops involving biological rhythms at Hopkins Marine Station. He has a  PhD in Zoology from the University of Washington where Jim Kenagy was his advisor. Dr. Barnes received his Post-doc in Psychology and Zoology with Irv Zucker and Paul Licht as advisors. He began as Assistant Professor at the University of Alaska in 1986.

Abstract:
In Alaska, winters begin early, last seemingly forever, are very cold, snowy and dark, as well as extremely beautiful, quiet, and serene. This talk will review the physiological and behavioral strategies available to animals for surviving and coping with arctic winters, including cryobiology in insects, freeze tolerance in frogs, and hibernation in ground squirrels and bears. Using data logging and advanced telemetry, the locations, behavior, sleep, circadian rhythms, cardiovascular patterns, and thermoregulation of animals were recorded as they overwinter under natural conditions.

Cucujus beetle larvae may not freeze at temperatures below -80C, wood frogs freeze almost solid and survive; arctic ground squirrels lose track of time, become torpid while colder than ice but warm to sleep, even as black bears continuously doze, only occasionally snore, and their hearts beat in a syncopated rhythm. Little is known about the genetic and molecular basis of hibernation, but discovering its mechanisms could lead to novel clinical therapies and escape strategies in humans.
