Biology 3445F Lecture Notes - Lecture 14: Cedar Creek Ecosystem Science Reserve, Complex Adaptive System, Simon A. Levin
Document Summary
Covers a wide range of different properties and components. Applied to a range of hierarchical levels: individual species abundances, community species composition, Holling published paper resilience and stability of ecological systems and defined. Stability: ability of a system to return to an equilibrium state after temporary disturbance. Resilience: a measure of the persistence and ability to absorb change and disturbance: community stability: ability of a community to defy change or rebound from change, stability has two main components: Resistance: the ability to maintain structure or function under disturbance. Resilience: the ability of the ecosystem to recover after disturbance. Resistance (left): the degree to which a variable changes after a perturbation or disturbance (robustness) Resilience (right): return time to an equilibrium/original state after perturbation or disturbance. Constancy (below): how variable the system is around an equilibrium point. Trophic complexity, redundancy, and food web structure (lecture 15) Rate of nutrient or energy flux (feedbacks among hierarchical levels)
