多物种的互惠关系是嵌入在一个网络的相互作用,包括捕食,但捕食对互惠功能的影响还没有很好地融入互惠理论。在捕食者被认为是,共同的预测是,捕食者减少互利丰富,因此,减少服务提供。在这里,我们使用一个数学模型的掠食性鱼类,消耗两个竞争的珊瑚互利,表明掠食者也可以有间接的积极影响主机时,他们优先消耗竞争优势互利,也较低的质量。在这些情况下,捕食扭转了竞争的结果,使更高质量的互惠者占主导地位,提高主机性能。捕食者效应的方向和强度取决于互惠竞争、服务提供和捕食脆弱性的不对称性。我们的研究结果表明,当捕食的强度发生变化时(例如,由于顶级捕食者的剥削性收获,新物种的引入,或响应气候变化的范围转移),互惠群落将表现出动态响应,对宿主服务提供的非单调效应。
Multispecies mutualisms are embedded in a network of interactions that include predation, yet the effects of predation on mutualism function have not been well integrated into mutualism theory. Where predators have been considered, the common prediction is that predators reduce mutualist abundance and, as a consequence, decrease service provision. Here, we use a mathematical model of a predatory fish that consumes two competing coral mutualists to show that predators can also have indirect positive effects on hosts when they preferentially consume competitively dominant mutualists that are also lower in quality. In these cases, predation reverses the outcome of competition, allowing the higher quality mutualist to dominate and enhancing host performance. The direction and strength of predator effects depend on asymmetries in mutualist competition, service provision, and predation vulnerability. Our findings suggest that when the strength of predation shifts (e.g., due to exploitative harvest of top predators, introduction of new species, or range shifts in response to climate change), mutualist communities will exhibit dynamic responses with nonmonotonic effects on host service provision.
