Abstract
Ecological structures and processes occur at specific spatiotemporal scales, and
interactions that occur across multiple scales mediate scale-specific (e.g., individual,
community, local, or regional) responses to disturbance. Despite the importance of scale,
explicitly incorporating a multi-scale perspective into research and management actions
remains a challenge. The discontinuity hypothesis provides a fertile avenue for addressing this
problem by linking measureable proxies to inherent scales of structure within ecosystems. Here
we outline the conceptual framework underlying discontinuities and review the evidence
supporting the discontinuity hypothesis in ecological systems. Next we explore the utility of
this approach for understanding cross-scale patterns and the organization of ecosystems by
describing recent advances for examining nonlinear responses to disturbance and phenomena
such as extinctions, invasions, and resilience. To stimulate new research, we present methods
for performing discontinuity analysis, detail outstanding knowledge gaps, and discuss
potential approaches for addressing these gaps.
