Simultaneous effects of food limitation and inducible resistance on herbivore population dynamics

摘要: Many herbivore populations fluctuate temporally, but the causes of those fluctuations remain unclear. Plant inducible resistance can theoretically cause population fluctuations, because herbivory may induce plant changes that reduce survival or reproduction later-feeding herbivores. Herbivory also simply quantity food available for later feeders and this, too, fluctuations. Inducible limitation often occur simultaneously, yet whether they jointly facilitate suppress remains largely unexplored. We present models suggest have synergistic effects on dynamics. The population-level response to details how affects performance both influence resulting Our results identify some biological properties plant-herbivore systems might determine not cycles occur, future empirical theoretical dynamics studies should account resistance.
