Abstract:
:Herbivory and dispersal play roles in the coexistence of primary producers with shared resource limitation by imposing trade-offs either through apparent competition or dispersal limitation. These mechanisms of coexistence can further interact with meta-ecosystem effects, which results in spatial heterogeneity through the movement of herbivores and nutrients. Here, we investigate how herbivores influence autotroph coexistence through a meta-ecosystem effect, and how this effect couples mechanisms of coexistence to ecosystem structure and functioning. We articulate this framework through a parameterized one resource-k producer-one herbivore meta-ecosystem model. The results show that herbivore movement with nutrient recycling can generate spatial heterogeneity to allow coexistence where the well-mixed system predicts competitive exclusion. Furthermore, the presence of movement alters local and regional ecosystem functioning even when coexistence would occur without movement. These results highlight how meta-ecosystem theory can provide a mechanistic context for the observed complexity of biodiversity-ecosystem function relationships.
