Symposium 6 - The detection of catastrophic thresholds: perspectives, definitions, and methods
Steamboat, Mezzanine Level, Cook Convention Center
Organized by: RA Washington-Allen (washingtonra@mac.com) and L Salo

This symposium is focused on the conception, definition, and detection of ecological thresholds or regime shifts, particularly on the operational use of catastrophe theory, time scale calculus, self-organization, scaling laws, and other aspects of complex systems science in natural resource management.
