Häiriönsietoisuus

Häiriönsietoisuus, often translated as resilience or disturbance tolerance, refers to the capacity of an ecosystem or organism to withstand disturbances and maintain its structure and function. Disturbances can range from natural events like fires, floods, and storms to human-induced impacts such as pollution, habitat destruction, and climate change. A high level of häiriönsietoisuus implies that an entity can absorb these shocks, resist significant changes, and potentially recover its original state or adapt to new conditions.

The concept is crucial in ecology and environmental science for understanding how ecosystems respond to stress. For instance, a forest with high häiriönsietoisuus might recover quickly after a fire, with native species regrowing and re-establishing ecological processes. Conversely, an ecosystem with low häiriönsietoisuus might undergo a phase shift, transforming into a fundamentally different type of ecosystem that is less diverse or functional.

Factors contributing to häiriönsietoisuus include biodiversity, which provides a wider range of species and functional groups to buffer against loss; ecosystem connectivity, allowing for recolonization and resource flow; and the inherent resistance of dominant species to the disturbance. Understanding häiriönsietoisuus helps in conservation efforts, resource management, and predicting the long-term impacts of environmental changes on natural systems. It is a key component in assessing the vulnerability and adaptability of both natural and managed environments.
