title: Interspecific abundance-occupancy relationships and the effects of disturbance: a test using microcosms.
abstract: The effects of disturbance on interspecific relationships between abundance and occupancy are tested using the results of a factorial experiment carried out with microcosm communities of protists. A positive relationship was documented whether marked disturbance was present or not; the pattern was neither a product of disturbance, nor was it destroyed by disturbance. Coefficients of determination, and the slopes and intercepts of abundance-occupancy relationships did not appear to change systematically with treatment. This robustness of the relationship may reflect the tendency for species to maintain approximately the same relative abundances and levels of occupancy in a broad range of circumstances.
