Disease Ecology Seminar: Yun Tao

"Movement Before the End of Time: Analyses of Transient Movement Dynamics and Their Applications in Disease Ecology," Yun Tao, Intelligence Community Postdoctoral Fellow at the University of California, Santa Barbara. 

Abstract: Animal movement research (an emerging discipline known as movement ecology) has experienced groundbreaking progress in recent years as a consequence of technological and methodological advancements. Animal (including human) movements are the outcome of dynamic interactions between the external environment and individual condition. However, many analytical models and statistical inferences are based around equilibrium space-use distributions that effectively average out transient dynamics over time. To date, this heavy reliance on equilibrium approaches has ignored a significant amount of dynamic information that reflects the behavioral mechanisms by which individuals respond to environmental changes – an increasingly important factor in the wake of accelerated human-induced disturbances. To address this issue, I developed an integrated set of transient movement models focused on exhuming ecologically significant movement dynamics that have been buried in previous steady-state models.

Using examples including home ranges and territorial patterns (conventionally modeled as invariant over time), I illustrate how transient analyses lead to a considerably improved understanding of ecological reality, exposures of short-term behavioral properties, and more powerful, testable predictions that better inform management strategies. I will conclude by exploring major questions in disease ecology and epidemiology that may be answered with the help of transient movement analysis. These results thus demonstrate a radical transformation in research shaped by a growing appreciation of movement transients: the capacity to reveal the past and project the future, enabling us to finally capture a dynamical world that has largely been lost in time.
