Catastrophic regime shifts in ecosystems: linking theory to observation
Occasionally, surprisingly large shifts occur in ecosystems. Theory suggests that such shifts can be attributed to alternative stable states. Verifying this diagnosis is important because it implies a radically different view on management options, and on the potential effects of global change on such ecosystems. For instance, it implies that gradual changes in temperature or other factors migh...
متن کاملSelf-organized patchiness and catastrophic shifts in ecosystems.
Unexpected sudden catastrophic shifts may occur in ecosystems, with concomitant losses or gains of ecological and economic resources. Such shifts have been theoretically attributed to positive feedback and bistability of ecosystem states. However, verifications and predictive power with respect to catastrophic responses to a changing environment are lacking for spatially extensive ecosystems. T...
متن کاملBifurcation theory and catastrophic shifts: from cancer evolution to complex ecosystems
The presence of qualitative changes in nonlinear systems’ dynamics is a key research topic with deep implications. Such implications range from potential tumor extinction under targeted cancer therapies to catastrophic ecological shifts in the face of environmental change. Bifurcations can govern these catastrophic shifts, which can be of different nature. In this talk we will discuss different...
متن کاملManaging for Variability to Sustain Freshwater Ecosystems
Water resources development for human needs has come at a significant cost to the natural functioning of aquatic and riparian ecosystems in the United States and around the world. The construction of hundreds of thousands of dams nationally and globally and the extensive human transformation of land cover have greatly modified the magnitude, timing, and duration of river flows that have histori...
متن کاملPredicting catastrophic shifts.
Catastrophic shifts are known to pose a serious threat to ecology, and a reliable set of early warning indicators is desperately needed. However, the tools suggested so far have two problems. First, they cannot discriminate between a smooth transition and an imminent irreversible shift. Second, they aimed at predicting the tipping point where a state loses its stability, but in noisy spatial sy...
