Inertia refers to the slow reaction of an ecosystem against inevitable external fluctuations. … On the other hand, resilience refers to the ability of an ecosystem to sustain against disturbances without bringing any change in the system and processes in an ecosystem.
What is the difference between inertia and resilience?
Inertia refers to the resistance to dis- turbance of an object or system, whereas the remaining four terms are properties of resilience, which refer to ways in which the disturbed system responds.
How is ecological inertia different from ecological resilience?
Inertia, the resistance of an ecosystem property to change under stress, is distinguished from resilience, which refers to the degree, manner, and pace of change or recovery in ecosystem properties following disturbance.
What is ecosystem inertia?
Definition: Refers to the delay or slowness in the response of an ecosystem to certain factors of change. Source: GreenFacts.
What is meant by ecosystem resilience?
Ecological resilience was defined as the amount of disturbance that an ecosystem could withstand without changing self-organized processes and structures (defined as alternative stable states). Other authors consider resilience as a return time to a stable state following a perturbation.
What is an example of ecological resilience?
For example, plants absorb phosphorus and limit algal growth in shallow lakes with low levels of phosphorus. An increase in phosphorus inputs, however, can lead to algal blooms that reduce light penetration and kill plants, releasing more phosphorus for algae.
What is an example of ecological inertia?
Tropical rain forests have high inertia because they have many different species resulting in a number of feeding paths and more ways to respond to environmental stresses allowing them to resist significant alteration or destruction as long as large areas are not degraded.
What are some examples of resilience?
What are some examples of resilience at work? Weathering a storm, bouncing back from adversity, seeing off challenges with stoicism and grit—these are brief, metaphorical resilience at work examples.
How does the atmosphere affect the functioning of ecosystems?
Key Points. Climate change can alter where species live, how they interact, and the timing of biological events, which could fundamentally transform current ecosystems and food webs. … Projected warming could greatly increase the rate of species extinctions, especially in sensitive regions.
Is a measure of an ecosystem stability?
An ecosystem is said to possess ecological stability (or equilibrium) if it is capable of returning to its equilibrium state after a perturbation (a capacity known as resilience) or does not experience unexpected large changes in its characteristics across time.
What are ecosystem services list two examples?
Examples of ecosystem services include products such as food and water, regulation of floods, soil erosion and disease outbreaks, and non-material benefits such as recreational and spiritual benefits in natural areas.
Which is the most stable ecosystem?
The ocean is the most stable ecosystem. It is stable due to its natural liquid nature (saline), dissolved oxygen, light and temperature.
What are the characteristics of a stable ecosystem?
The two key components of ecosystem stability are resilience and resistance. Resistance is an ecosystem’s ability to remain stable when confronted with a disturbance. Resilience is the speed at which an ecosystem recovers from a disturbance.
What is the difference between ecosystem resistance and resilience?
Resistance is the ability for an ecosystem to remain unchanged when being subjected to a disturbance or disturbances. … Resilience is the ability and rate of an ecosystem to recover from a disturbance and return to its pre-disturbed state.
What 3 factors determine the resilience of an ecosystem?
At the landscape level, the amount of intact habitat , connectivity , and variation (or heterogeneity) in the landscape are important properties affecting resilience (Oliver et al.
What are the characteristics of resilient ecosystems?
Ecologists Brian Walker, C S Holling and others describe four critical aspects of resilience: latitude, resistance, precariousness, and panarchy. The first three can apply both to a whole system or the sub-systems that make it up.
