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.
利用针对原生生物微观群落进行的析因实验结果，测试了干扰对丰度与占有率之间种间关系的影响。无论是否存在显著干扰，均记录到一种正相关关系；这种模式既不是干扰的产物，也不会被干扰破坏。决定系数以及丰度 - 占有率关系的斜率和截距似乎不会随处理方式而系统性地变化。这种关系的稳健性可能反映了物种在广泛情况下倾向于维持大致相同的相对丰度和占有率水平。
