摘要: 1. Food-web complexity-stability relations are central to ecology, and many empirical studies show greater food-web complexity leads lower population stability. Here, predator variability decreased with increasing prey diversity in aquatic microcosm experiments, an example of leading 2. Prey as well different sets species within each level produced differences dynamics, demonstrating the importance both composition determining 3. can affect dynamics through at least three groups mechanisms: reliability, biomass, mechanisms. The results suggest that reliability higher diversities enhances stability provide support for MacArthur (1955).
