捕食者和猎物物候的差异变化是一个潜在的重要气候介导的机制影响人口。匹配失配假说描述了捕食者-猎物种群同步对捕食者发育和生存的影响，并用于描述气候对猎物控制的陆地和海洋生态系统中生态模式和过程的影响。我们评估的假设，考虑更广泛的影响，捕食者-猎物的同步猎物的常备股票和生存，除了它的证据确凿的影响捕食者。具体而言，我们认为，在捕食者和猎物之间的峰值丰度的增加，可能会导致增加生存和潜在的增加招聘的猎物在某些系统。利用广义可加模型，我们证明了匹配失配假设不仅适用于食饵控制系统，也适用于捕食者控制系统。
Differential change in the phenology of predators and prey is a potentially important climate-mediated mechanism influencing populations. The match-mismatch hypothesis describes the effect of predator-prey population synchrony on predator development and survival and is used to describe climate effects on ecological patterns and processes in prey-controlled terrestrial and marine ecosystems. We evaluated the hypothesis by considering the broader effects of predator-prey synchrony on prey standing stock and survival in addition to its well documented effects on the predator. Specifically, we suggest that an increase in asynchrony between predator and prey peak abundance can lead to increased survival and potentially increased recruitment of the prey in some systems. Using generalized additive models, we demonstrated that the matchmismatch hypothesis can be used not only for prey-controlled systems, but also for predatorcontrolled systems.
