Multi?scale biodiversity drives temporal variability in macrosystems

High temporal variability in environmental conditions, populations, and ecological communities can result species extinctions outbreaks of agricultural pests disease vectors, as well impact industries dependent on reliable provisioning ecosystem services. Yet few empirical studies have focused testing hypotheses about the drivers at large spatial scales. Using decadal datasets that span aquatic terrestrial macrosystems structural equation modeling, we show local synchrony increase for entire macrosystems. These mechanisms are influenced by heterogeneity, habitat-level diversity, scale, size regional pool. This analysis is among first to provide a quantitative argument value diversity. Moreover, our conceptual model generalizable may help guide management efforts reduce conservation or service other
