MULTI-SCALE BIODIVERSITY DRIVES STABILITY IN MACROSYSTEMS
Although it is understood that local ecosystems are embedded within larger interconnected macrosystems (e.g. riverine networks), with processes and functions interacting at multiple scales, relatively little work has empirically investigated these phenomenon. Additionally, it is of great economic importance to understand what regulates temporal stability in ecosystem services (e.g. fisheries) and disservices (e.g. disease-vectors). Here we present results from four macrosystems: mid-Atlantic stream fish, freshwater macrophytes in upper Chesapeake Bay, seagrass in lower Chesapeake Bay, and ground beetles in Phoenix, AZ. Across case studies, we found support for our hypothesis that within site stability and asynchrony combine to influence macrosystem stability, but among systems, within site stability tended to explain more temporal variation than asynchrony. Importantly, gamma-richness, mean alpha-richness, beta-diversity, and environmental heterogeneity were key underlying drivers that increased macrosystem stability. Differences among systems suggested that environmental gradients within a system may alter the relationship between regional biodiversity and macrosystem stability. Overall, this work suggests that maintaining regional biodiversity is important for promoting macrosystem stability. However, more work is needed to better understand the mechanisms driving differences among systems.
