In ecology, resilience is the capacity of an ecosystem to respond to a perturbation or disturbance by resisting damage and subsequently recovering. Such perturbations and disturbances can include stochastic events such as fires, flooding, windstorms, insect population explosions, and human activities such as deforestation, fracking of the ground for oil extraction, pesticide sprayed in soil ...
Following this strategy, an ecosystem which oscillates cyclically around a fixed point, such as the one delineated by the predator-prey equations, would be described as persistent and resilient, but not as constant. Some authors, however, see good reason for the abundance of definitions, because they reflect the extensive variety of real and ...
“Temperate grasslands are the most imperiled ecosystem on Earth,” said Kristy Bly, a restoration manager for the World Wildlife Fund’s Northern Great Plains program. ... “A resilient ...
Ecosystems are resistant to state shifts – they will only undergo shifts under substantial perturbations – but some states are more resilient than others. In the ball-and-cup model, a valley with steep sides has greater resilience than a shallow valley, since it would take more force to push the ball up the hill and out of the valley.
Some lichens grow on rocks without soil, so may be among the first of life forms, and break down the rocks into soil for plants. [11] Since some uninhabited land may have thin, poor quality soils with few nutrients, pioneer species are often hardy plants with adaptations such as long roots, root nodes containing nitrogen-fixing bacteria, and leaves that employ transpiration.
The grassfire was the most destructive fire in Colorado history. ... a natural ecosystem that burns,” said Steinberg. ... Research by Headwaters Economics shows that becoming wildfire resilient ...
The basis of the IUCN Red List of Ecosystems are the IUCN Red List of Ecosystems Categories and Criteria, a set of eight categories and five criteria that provide a consistent method for assessing an ecosystem's risk of collapse. They are designed to be: broadly applicable across type ecosystems and geographic areas, transparent and ...
Tongva community leaders credit traditional stewardship practices, including the removal of fire-prone eucalyptus, with reducing the wildfire's impact.
