Basic concepts, emerging challenges and new opportunities in movement ecology: Ten years after PNAS
Hebrew University of Jerusalem, Israel
The emerging field of movement ecology largely benefited from the recent development in wildlife tracking technologies, enhanced computation abilities and powerful data analysis tools. Movement ecology studies have utilized those technological advances, along with new conceptual/theoretical frameworks, to elucidate movement patterns, the underlying movement processes and their ecological and evolutionary consequences. Despite these significant advances, some of the key questions on how movement shapes the ecology, behavior and evolution of organisms across multiple spatial and temporal scales remain unresolved. In this talk, I will highlight some of the most exciting developments and challenges in movement ecology since the introduction of this paradigm in a Special Feature published in PNAS ten years ago. These include (i) reexamination of previous dogmas, conceptions and assumptions that have long underlied ecological, behavioral and evolutionary research; (ii) promises and difficulties in the forthcoming Big Data revolution generated by the recent burst of high-throughput tracking technologies; and (iii) new opportunities to address big unanswered questions such as Why do young inexperienced animals die and how they improve performance with age and experience? How do animals find their way in the dark? and Why only a few migrating herbivorous waterbirds follow the green wave?
