Ecological Concept: Resilience and Resistance. 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.
RESISTANCE – measure of how much a disturbance can affect the flows of every & matter. RESILIENCE – rate at which an ecosystem returns to its original state.
Likewise, what does it mean for an ecosystem to be resilient? In ecology, resilience is the capacity of an ecosystem to respond to a perturbation or disturbance by resisting damage and recovering quickly.
Also Know, what is the difference between resistance and resilience?
As nouns the difference between resilience and resistance is that resilience is the mental ability to recover quickly from depression, illness or misfortune while resistance is the act of resisting, or the capacity to resist.
What is an example of ecological resilience?
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 do you mean by resistance?
Resistance is the opposition that a substance offers to the flow of electric current. When an electric current of one ampere passes through a component across which a potential difference (voltage) of one volt exists, then the resistance of that component is one ohm.
What makes ecosystems resistant to disturbances?
Resistance is the ability for an ecosystem to remain unchanged when being subjected to a disturbance or disturbances. Low resistance can sometimes be advantageous, such as in ecosystems that rely on natural disturbances to temporarily change their conditions in order to remain stable over the long term.
What determines the productivity of a community?
What determines the productivity of a community? Sunlight, water, trace elements (nitrogen) and minerals that plants can collect from the ground. That is, the tropical regions are the most productive regions on land.
How does energy flow through an ecosystem?
Organisms can be either producers or consumers in terms of energy flow through an ecosystem. Producers convert energy from the environment into carbon bonds, such as those found in the sugar glucose. A trophic level refers to the organisms position in the food chain. Autotrophs are at the base.
What are the dominant elements that make up living organisms?
Living organisms often contain trace amounts of several elements, but the most abundant ones are oxygen, carbon, hydrogen, nitrogen, calcium and phosphorus. Oxygen. Oxygen is the most abundant element contained within living organisms, composing about 65% of the human body. Carbon. Hydrogen. Nitrogen. Sulfur. Phosphorus.
Why is ecological resilience important?
Resilience is the ability of an ecosystem to resist or recover from disturbance. A healthy, diverse ecosystem usually recovers quickly, because they have more options for dealing with different types of disturbance. Diversity is also important because usually many organisms are needed to repair ecosystem damage.
What does the Hubbard Brook study teach us?
What does it teach us? Hubbard Brook is a valuable study area because it is an ideal watershed area. Researchers using the Hubbard Brook was able to determine that when trees are no longer there to take up the soil nitrate, it leaches out of the soil and ends up in the stream which drains into the watershed.
What are the main similarities and differences among the carbon nitrogen and phosphorus cycles?
What are the main similarities and differences between carbon nitrogen and phosphorus cycles? They all haver water components but the phosphorus cycle, has no atmospheric component.
What are some examples of environmental resistance?
Environmental resistance factors are things that limit the growth of a population. They include biotic factors – like predators, disease, competition, and lack of food – as well as abiotic factors – like fire, flood, and drought. The biotic potential of a population is how well a species is able to survive.
What makes an ecosystem more resilient to change?
He stated that ecosystem stability increased as the number of interactions (complexity) between the different species within the ecosystem also increased. This elasticity means that ecosystem properties, such as changes in nutrient flow or the number of species, are more resilient due to changes in species composition.
How is resilience defined?
Resilience, from the Latin resilire (to rebound, recoil, or spring back), is a general concept that can be defined broadly as follows: The capacity of a dynamic system to withstand or recover from significant challenges that threaten its stability, viability, or development.
What is meant by environmental resistance?
Definition of environmental resistance. : the sum of the environmental factors (such as drought, mineral deficiencies, and competition) that tend to restrict the biotic potential of an organism or kind of organism and impose a limit on numerical increase.
Which is correct resilience or resiliency?
It doesn’t matter because they are, as you suggest, exact synonyms, except for the pretentiousness of the longer word: resiliency. All verbosity is pretentious. Resilience is the more accepted form in the USA. [I]n today’s English, resilience is far more common than resiliency, especially outside the U.S. and Canada.
What is the process of succession?
Ecological succession is the process of change in the species structure of an ecological community over time. It is a phenomenon or process by which an ecological community undergoes more or less orderly and predictable changes following a disturbance or the initial colonization of a new habitat.
