Though predation, productivity (nutrient richness), spatial heterogeneity, and disturbance regimes are known to influence species diversity, interactions between these factors remain largely unknown. Predation has been shown interact with but few experimental studies have focused on how predation prey diversity. We used theory experiments investigate diversification of Pseudomonas fluorescens by manipulating both (presence or absence Bdellovibrio bacteriovorus) (frequency intensity disturbance). Our results show that in a homogeneous environment, is essential promote However, most not all treatments, elevated diversity was transitory, implying the effect strongly influenced disturbance. Both our theoretical suggest interacts modifying interplay resource apparent competition among prey.
