There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Most examples of self-organized spatial patterns in ecosystems are based on Alan Turing's activator-inhibitor principle, where pattern formation is driven by spatial variation in biological growth conditions. I will highlight a new mechanism of pattern formation in ecosystems that is based on the individual movement of animals, and is akin to the physical principle for phase separation, known to explain pattern formation in alloys such as steel or bronze. Using models and experiments, I will argue that both processes can occur simultaneously, and interact to determine the resilience of ecosystems to disturbances and changing environmental conditions.
