Increasing species diversity can influence ecosystem functions — such as productivity — by increasing the likelihood that species will use complementary resources and can also increase the likelihood that a particularly productive or efficient species is present in the community.
What is the relationship between biodiversity and ecosystem stability?
Generally speaking, greater species diversity (alpha diversity) leads to greater ecosystem stability. This is termed the “diversity–stability hypothesis.” An ecosystem that has a greater number of species is more likely to withstand a disturbance than an ecosystem of the same size with a lower number of species.
How does biodiversity affect ecosystem stability and primary productivity?
Biodiversity was linked to an increased temporal stability of primary productivity, which again suggests that BEF relationships observed in experiments with small plots (2) also apply in natural systems at the landscape scale. … The strong biodiversity effects we found thus are all the more remarkable.
How does biodiversity help with ecosystem productivity?
Biodiversity boosts ecosystem productivity where each species, no matter how small, all have an important role to play. For example, A larger number of plant species means a greater variety of crops. … Healthy ecosystems can better withstand and recover from a variety of disasters.
Biodiversity is a measure of the complexity of interactions in a given habitat or ecosystem. … Ecological productivity is a measure of the rate of generation of biomass or carbon per area of habitat or ecosystem. The more biomass (living organisms and organic matter) produced, the greater the productivity.
Why does biodiversity increase the stability of an ecosystem?
It has been shown that biodiversity of an area has a large impact on the ecosystem stability of that area. … This increase in complexity makes it more likely that the ecosystem will return to a stable state after a disturbance, because the ecosystem has more ways to respond to a disturbance and fix problems.
Why is biodiversity important to the stability of an ecosystem?
Biodiversity boosts ecosystem productivity where each species, no matter how small, has an important role to play. For example, A larger number of plant species means a greater variety of crops. … Healthy ecosystems can better withstand and recover from a variety of disasters.
What is the relationship between diversity and stability?
Increased alpha diversity (the number of species present) generally leads to greater stability, meaning an ecosystem that has a greater number of species is more likely to withstand a disturbance than an ecosystem of the same size with a lower number of species.
What are the relation among diversity productivity and stability?
New insights from recent studies support the hypothesis that species diversity enhances productivity and stability in some ecosystems, but not in others. Appreciation is growing for the ways that particular ecosystem features, such as environmental variability and nutrient stress, can influence biotic interactions.
Why does biodiversity increase productivity?
Using data from more than 400 published experiments, an international research team has found overwhelming evidence that biodiversity in the plant kingdom is very efficient in assimilating nutrients and solar energy, resulting in greater production of biomass. …
Why is biodiversity so important and worthy of protection?
Healthy ecosystems clean our water, purify our air, maintain our soil, regulate the climate, recycle nutrients and provide us with food. … Biodiversity is the key indicator of the health of an ecosystem. A wide variety of species will cope better with threats than a limited number of them in large populations.
