物种多样性是否有助于生态系统的稳定性一直是群落生态学中争论的热点之一。不同生态系统物种的潜在不同贡献尚未得到明确考虑。以无花果种及其伴生的榕小蜂群落为模型系统，通过建立无花果-榕小蜂食物网模型，将群落结构纳入“多样性-稳定性”的争论中。模型模拟结果表明，传粉小蜂寄生蜂的种群密度对小蜂多样性有促进作用，寄生蜂的自上而下的控制对群落多样性和稳定性起着调节作用。此外，只有适度的传粉者寄生导致在榕榕小蜂群落的规则/不规则振荡共存。在榕小蜂生物多样性较低的情况下，小蜂多样性的增加可以提高群落的稳定性，而种群的混乱则可以维持榕小蜂系统中小蜂的多样性。我们的理论预测是一致的最新的实验研究的无花果-无花果黄蜂系统，这表明，自上而下的控制（寄生虫的传粉）的损失导致在互惠互利的平衡的变化，从而改变食物网的复杂性。
Whether species diversity contributes to the ecosystem stability has been one of the most heated arguments in community ecology. Potentially different contributions of different ecosystem species have not been explicitly taken into account. With fig species and their associated fig wasp community as model system, we bring community structure into the “diversity-stability” debate by establishing the fig-fig wasp food web model. The simulations of our model indicated that wasp diversity was promoted by population density of the parasitoids of the pollinating wasps, and that top-down control from the parasitoids regulated community diversity and stability. Moreover, only moderate parasitoidism on the pollinators resulted in the regular/irregular oscillatory coexistence in the fig-fig wasp community. Increases in the wasp diversity could increase community stability when biodiversity of fig wasps was low, while population chaos would maintain wasp diversity in the fig-fig wasp system. Our theoretical predictions are consistent with the newest experimental study on the fig-fig wasp system, which showed that loss of top-down control (parasitoidism on the pollinators) resulted in a change in the balance of reciprocal benefits, thereby changing food web complexity.
