Orr Spiegel has recently joined the School of Zoology (summer 2018). He studies movement ecology and animal behavior, in particular the importance of individual variation. Orr completed his graduate studies at the Hebrew University of Jerusalem and continued to postdoc studies at the University of California, Davis (4 years), and Ben Gurion university of the Negev (1 year). For his B.Sc. he combined Life and Earth Sciences (Geology) and during his M.Sc. he studied seed dispersal by desert passerines. His Ph.D. focused on foraging movements of vultures in Israel and Namibia and for his postdoc he tracked sleepy lizards in Australia and Nubian Ibex in the Judean desert, Israel. His lab investigates what are the ultimate and proximate factors that shape animal behavior and movement, and how the emerging movement patterns drive ecological and evolutionary dynamics.

The overarching goal of our lab is to explore the socio-ecological factors that affect animal space-use, and the consequences of these movements for the fitness of individuals, population dynamics, the roles species take within their ecosystem as well as for their conservation. Movement integrates animals’ response to their environment across a wide range of spatial and temporal scales, ranging from day-to-day local foraging to once-in-a-lifetime, cross-continental dispersal events. Recent empirical and theoretical studies suggest that individuals differ consistently in their movements and this notion can facilitate progress in various topics, including basic and applied (conservation) sciences.
More broadly, Understanding the patterns and mechanisms of movement decisions is a long lasting challenge in ecology and evolutionary biology with implications for many processes at the population level such as social networks, disease dynamics, colonization, optimal foraging as well as for animals response to habitat fragmentation and conservation of natural systems. Yet, many of the models and concepts in these diverse disciplines use oversimplified representation of movement (e.g., assuming it to be random when it is clearly structured, or ignoring constraints- e.g., the ideal free distribution). Therefore, we believe that studies of movement ecology will provide potential insights into many of these processes and to our ability to model them better.
