How does biodiversity affect ecosystem processes?
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.
Why is species diversity so important for a functioning 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. Greater species diversity ensures natural sustainability for all forms of life.
How does species diversity affect ecosystem stability?
Greater biodiversity in ecosystems, species, and individuals leads to greater stability. For example, species with high genetic diversity and many populations that are adapted to a wide variety of conditions are more likely to be able to weather disturbances, disease, and climate change.
What is functional diversity in ecosystem?
Functional diversity is a component of biodiversity that generally concerns the range of things that organisms do in communities and ecosystems. Here, we review how functional diversity can explain and predict the impact of organisms on ecosystems and thereby provide a mechanistic link between the two.
What is the effect of biodiversity on ecosystem productivity?
What is the effect of biodiversity on ecosystem productivity? Increased biodiversity increases productivity.
Why is biodiversity important for ecosystem structure and function?
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. Greater species diversity ensures natural sustainability for all life forms.
How does biodiversity contribute to the sustainability of an ecosystem?
The higher biodiversity in an ecosystem means that there is a greater variety of genes and species in that ecosystem. A great variety of genes and species means that the ecosystem is better able to carry out natural processes in the face of external stress. Thus, the ecosystem is more sustainable.
What is the role of species in an ecosystem?
Key Concept Any given species may play one or more of 5 important roles – native, nonnative, indicator, keystone, or foundation – in a particular 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.
Increased genetic diversity leads to increased chance of species survival. Species with a limited variety of phenotypes and where all members of the species are similar to one another have a smaller chance of coping with environmental variability compared to a species with greater diversity.
Does high species diversity always increase ecosystem stability?
Viewpoint: No, ecosystem stability may provide a foundation upon which diversity can thrive, but increased species diversity does not confer ecosystem stability.
What is an example of functional diversity?
Some examples include understanding species competitive abilities, patterns of species co-occurrence, community assembly, and the role of different traits on ecosystem functioning.
Why are functional traits important?
A need to develop better predictive capacity for how species respond to environmental change has in part motivated this focus. Functional traits are of most interest—those with a defined link to individual survival, development, growth and reproduction.
