Early Warning Signals of Ecological Transitions: Methods for Spatial Patterns
A number of ecosystems can exhibit abrupt shifts between alternative stable states. Because of their important ecological and economic consequences, recent research has focused on devising early warning signals for anticipating such abrupt ecological transitions. In particular, theoretical studies show that changes in spatial characteristics of the system could provide early warnings of approac...
متن کاملself-organized vegetation patterns: early warning signals for predicting ecosystem transitions
the significance of spatial heterogeneity in understanding ecological processes has been recognized long ago. one of the earliest expressions of this recognition is the habitat heterogeneity hypothesis that links spatial heterogeneity to niche vegetation patterns formation and species coexistence. yet, an important if not crucial aspect of landscape heterogeneity has escaped deep considerati...
متن کاملEarly warning signals for critical transitions in a thermoacoustic system
Dynamical systems can undergo critical transitions where the system suddenly shifts from one stable state to another at a critical threshold called the tipping point. The decrease in recovery rate to equilibrium (critical slowing down) as the system approaches the tipping point can be used to identify the proximity to a critical transition. Several measures have been adopted to provide early in...
متن کاملEarly Warning Signals for Critical Transitions: A Generalized Modeling Approach
Critical transitions are sudden, often irreversible, changes that can occur in a large variety of complex systems; signals that warn of critical transitions are therefore highly desirable. We propose a new method for early warning signals that integrates multiple sources of information and data about the system through the framework of a generalized model. We demonstrate our proposed approach t...
متن کاملCatastrophic Collapse Can Occur without Early Warning: Examples of Silent Catastrophes in Structured Ecological Models
Catastrophic and sudden collapses of ecosystems are sometimes preceded by early warning signals that potentially could be used to predict and prevent a forthcoming catastrophe. Universality of these early warning signals has been proposed, but no formal proof has been provided. Here, we show that in relatively simple ecological models the most commonly used early warning signals for a catastrop...
