TL;DR: The conceptual framework underlying discontinuities is outlined and the evidence supporting the discontinuity hypothesis in ecological systems is reviewed, and the utility of this approach for understanding cross-scale patterns and the organization of ecosystems is explored.

TL;DR: This work tested a long-term high-resolution paleoecological dataset with a known change in species assemblage for a regime shift and showed that there was a∼2000 year period of instability prior to the regime shift, indicating that the system is undergoing extrinsic forcing.

TL;DR: In this article, an approach based on discontinuity theory that accounts for patterns and processes at distinct spatial and temporal scales, an inherent property of ecological systems, is proposed to measure and understand the resilience of ecosystems, to objectively identify critical scales of space and time in ecological systems at which human impact might be most severe.

TL;DR: The theory, data, and methodology necessary for using Fisher information to assess the sustainability of the San Luis Basin (SLB) regional system over time are described and it is revealed that the SLB system is stable with very slight movement away from sustainability in more recent years.

TL;DR: The results suggest that defining spatial regimes based on animal communities may better reflect ecological reality than do traditional ecoregion maps, especially in the current era of rapid and unpredictable ecological change.
