Towards a Meta-Ecosystem Perspective of Aquatic-Terrestrial Linkages
A "meta-ecosystem" as a set of spatially isolated ecosystems that exchange energy, materials, and organisms. Reciprocal (bi-directional) exchanges of resources and consumers between aquatic and terrestrial ecosystems make them a model for studying meta-ecosystems. A central feature of meta-ecosystems are feedbacks produced bi-directional resource flows. But currently we typically study linkages between aquatic and terrestrial ecosystems uni-directionally, and only focus on one linkage at a time. Here we argue that new insights can be gained by explicitly integrating feedbacks, and multiple linkage types, into empirical studies of aquatic-terrestrial linkages. We present the results of a theoretical meta-ecosystem model with two three-trophic level ecosystems, one approximating a high-energy flux system ("aquatic") and another approximating a low-energy flux system ("terrestrial"). We then vary and examine the effects of consumer fluxes and resource fluxes from one system to the other, with and without allowing feedbacks between each system to occur, and explore their consequences on meta-ecosystem dynamics. We find that when we allow feedbacks to occur, and when multiple linkages are considered, the effects of resource additions and consumer removals lead to different outcomes.
