Tropical rainforests have high inertia because they have many different species, resulting in a range of foraging pathways and more opportunities to respond to environmental stresses, allowing them to undergo significant change or destruction long as large areas are not degraded.
Definition: Refers to the lag or slowness in an ecosystem’s response to specific change factors.
Ecological inertia is the ability of an ecosystem to survive moderate disturbances. A tropical rainforest can withstand minor changes or damage. Ecological resilience is the ability of an ecosystem to recover after severe disturbance by secondary ecological succession.
Summary. Resilience of a natural ecosystem here refers to the ecosystem’s ability to repair itself after disturbances and inertia to its ability to resist change when stressed.
Stability can be defined at the ecosystem level – for example, a rancher might be interested in the ability of a grassland ecosystem to sustain primary production for cattle feed over a number of years that may vary in their mean temperature and rainfall.
Ecological resilience, also called ecological robustness, the ability of an ecosystem to maintain its normal patterns of nutrient cycling and biomass production after suffering damage from an ecological disturbance.
More complex ecosystems are more resilient or better able to tolerate and recover from disturbances than less complex ecosystems. To illustrate why this is so, imagine a complex ecosystem with many components and many interactions between those components.
An example of resilience is the response of many Americans to the September 11, 2001 terrorist attacks and the efforts of individuals to rebuild their lives. Demonstrating resilience doesn’t necessarily mean you haven’t experienced difficulties or stress.
At the landscape level, the amount of intact habitat, connectivity, and variation (or heterogeneity) in the landscape are important characteristics affecting resilience (Oliver et al.
In general, resistance is characterized as the impact of structure and composition on a perturbation, while resilience is characterized as the impact of a perturbation on subsequent structure and composition.
Biodiversity measurement is helpful in determining the stability of ecosystems. Biodiversity is a measure that combines richness and uniformity across species. It is often measured because high biodiversity is seen as synonymous with a healthy ecosystem.
A Climax community is a definitive and stable community. Even if a climax community continues to change slightly, that type of community can remain the same over time if not disrupted. Natural fires caused by lightning are a necessary part of secondary succession in some communities.
* Tropical forests have high biodiversity/inertia, but once badly damaged they have low resilience. * Grasslands are much less diverse than most forests, and consequently they have low inertia and can burn easily.
Oceans are the most stable ecosystems. Other terrestrial ecosystems are subject to changes and sequences of biotic components. But the oceans remain stable for a long time.
The two key components of ecosystem stability are resilience and resistance. Resilience is the ability of an ecosystem to remain stable when faced with a disturbance. Resilience is the speed at which an ecosystem recovers from a disruption.
The terrestrial ecosystem is based on the land of living and non-living things such as grasslands, deserts and forests. Based on the information above, the (c)pond is not an example of a terrestrial ecosystem in the options given.
The aquatic biome is the largest of all biomes, covering approximately 75% of the Earth’s surface. This biome is usually divided into two categories: freshwater and marine. Typically, freshwater habitats contain less than 1 percent salt.
Human actions that result in changes in land use, nutrient cycling, hydrology, or pollution levels can reduce ecosystem resilience.
Many believe that
coral reefs have the greatest biodiversity of any ecosystem on the planet – even more so than a tropical rainforest. Coral reefs occupy less than 1 percent of the ocean floor and are home to more than 25% of all marine life.
