"WebbOur results reveal that in a changing environment, the community can track states that are unstable in the constant environment. This tracking can lead to regime shifts, including local extinctions, that are not predicted by alternative stable state theory. " - Theory of alternative stable states

Often the … Webb25 feb. 2015 · Alternative stable states in ecology have been well studied in isolated, well-mixed systems. However, in reality, most ecosystems exist on spatially extended landscapes. Applying existing theory from dynamic systems, we explore how such a spatial setting should be expected to affect ecological resilience.

Visa mer In ecology, the theory of alternative stable states (sometimes termed alternate stable states or alternative stable equilibria) predicts that ecosystems can exist under multiple "states" (sets of unique biotic and abiotic conditions). … Visa mer Ecosystems can shift from one state to another via a significant perturbation directly to state variables. State variables are quantities that change quickly (in ecologically-relevant time scales) in response to feedbacks from the system (i.e., they are … Visa mer Hysteresis is an important concept in alternative stable state theory.

This is known as the ecosystem perspective. This perspective requires a change in environmental parameters that affect the behavior of state variables. For … Visa mer By their very nature, basins of attraction display resilience.
