title: Disaster, Catastrophe, and Local Persistence of the Sea Palm Postelsia palmaeformis.
abstract: Two components of natural disturbance, its local intensity and frequency beyond a threshold level, limit a marine benthic alga to wave-swept shores. Transplant experiments indicate that the limited distribution is not due to physiological restriction. Instead, it requires predictable annual disturbance of moderate intensity for local persistence.
