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 does high biodiversity mean for an ecosystem?
Biodiversity refers to the variety of life. When biodiversity is high, it means there are many different types of organisms and species. … And every organism plays a unique role and contributes to how coral reef communities survive and function.
Why is it important for ecosystems to have a high diversity?
Ecological life support— biodiversity provides functioning ecosystems that supply oxygen, clean air and water, pollination of plants, pest control, wastewater treatment and many ecosystem services. Recreation—many recreational pursuits rely on our unique biodiversity , such as birdwatching, hiking, camping and fishing.
Are ecosystems more resilient if they have high biodiversity?
Biologically diverse communities are also more likely to contain species that confer resilience to that ecosystem because as a community accumulates species, there is a higher chance of any one of them having traits that enable them to adapt to a changing environment.
What causes high biodiversity?
Ecosystems that host the most biodiversity tend to have ideal environmental conditions for plant growth, like the warm and wet climate of tropical regions. Ecosystems can also contain species too small to see with the naked eye.
How does high biodiversity affect an ecosystem apex?
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 are some examples of ecosystems with high biodiversity?
Example of ecosystem with high biodiversity is tropical rain forest as seen in Amazon basin of south America. Such forests are also thriving in parts of central Africa and also in islands of Indonesia. In marine environment, coral reefs are example of high biodiversity aquatic ecosystems.
How does biodiversity affect the environment?
A diversity of species increases the ability of ecosystems to do things like hold soils together, maintain soil fertility, deliver clean water to streams and rivers, cycle nutrients, pollinate plants (including crops), and buffer against pests and diseases—these are sometimes called ‘ecosystem functions’ or ‘ecosystem …
How does biodiversity affect ecosystem services?
Many key ecosystem services provided by biodiversity, such as nutrient cycling, carbon sequestration, pest regulation and pollination, sustain agricultural productivity. Promoting the healthy functioning of ecosystems ensures the resilience of agriculture as it intensifies to meet growing demands for food production.
What is the effect of biodiversity on ecosystem productivity?
According to the insurance hypothesis, biodiversity insures ecosystems against declines in their functioning because many species provide greater guarantees that some will maintain functioning even if others fail.
How does biodiversity make ecosystems more resilient?
This research showed that diverse communities are more stable because they exhibit resistance during extreme climate events.” … Instead, resistance to change clearly superseded resilience as the main mechanism by which biodiversity helps to preserve ecosystem stability in the face of climatic extremes, he said.
What are the effects of biodiversity loss?
Biodiversity loss can have significant direct human health impacts if ecosystem services are no longer adequate to meet social needs. Indirectly, changes in ecosystem services affect livelihoods, income, local migration and, on occasion, may even cause or exacerbate political conflict.
What supports high biodiversity?
Wetlands have been called “biological super systems” because they produce great volumes of food that support a remarkable level of biodiversity. In terms of number and variety of species supported, they are as rich as rainforests and coral reefs.
