How does biodiversity increase the stability of ecosystems?
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.
Why is biodiversity important?
All the great benefits from biodiversity highlighted above depend on our nature being just that, diverse. For any ecosystem to function it needs a lot of components , and removing any of these will make this complex system weaker, or even make it collapse . Environments that are poor in diversity, like commercial monocultures of a single species of tree, crop or fish, have proven to be very fragile and can provide fewer, and lesser quality, benefits to people. So the more biodiverse an ecosystem or landscape is, the greater its resilience to pressures such as climate change.
How does biodiversity affect agriculture?
Growing crops and rearing animals, would not be possible without the numerous and complex interactions that happen below and above ground between different species. Fertile soils, pollination of crops, natural control of agricultural pests and the detoxification and decomposition of waste all contribute to cost and resource-effect ive production.

Why is it important to protect genetic resources of food plants?
Drastic global climatic changes may cause large-scale shifts in natural vegetation and agricultural crops. Hence there is urgent need to protect genetic resources of food plants to maintain crop productivity in different climatic conditions. There are several species of useful plants in the tropics alone that could be used as an alternative source. Their uses could be extended from emergency sustenance in isolated locations or disaster areas to fully exploitable alternative sources of food.
Which region has the richest biodiversity?
Tropical regions are having the richest biodiversity in the world, most of the nutrients are lodged in its biotic community. Due to warm and humid conditions decomposition of organic matter and regeneration of nutrients take place rapidly.
How does biodiversity protect the ecosystem?
Biodiversity protects against drought and erosion. It also regulates chemical composition of the soil and the atmosphere and determines the reproductive seasons of animals and the growth cycle of plants. Biodiversity keeps the ecosystem at an equilibrium, which defines the manner in which living organisms interact.
Why is biodiversity important?
Follow Us: Biodiversity is important in ecosystems because it prevents extinction of species, allows organisms to adapt to changes in the environment and provides a wide range of materials and foods for survival. Biodiversity is categorized into species diversity, genetic diversity ...
How does biodiversity affect the environment?
Biodiversity creates a well-functioning ecosystem, which cleanses water and air resources, minimizing the effects of pollution. Rain forests contain 50 percent of the world’s animal and plant species. The biodiversity of these forests regulates weather patterns on Earth.
What are the threats to biodiversity?
Biodiversity is threatened by climate change, pollution, overexploitation of natural resources and habitat loss. Within a biologically diverse ecosystem, living organisms depend on one another for survival. For example, animals depend on plants for food and shelter, and plants depend on the soil for growth.
Why do plants depend on bees?
Plants also depend on bees for pollination and reproduction. Fungi and bacteria decompose other organisms to fertilize the soil. Loss of biodiversity weakens the connections that exist among various species, which harms the ecosystem. ADVERTISEMENT.
Why does biodiversity increase closer to the equator?
It is not yet clear why biodiversity increases closer to the equator, but hypotheses include the greater age of the ecosystems in the tropics versus temperate regions, which were largely devoid of life or drastically impoverished during the last ice age. The greater age provides more time for speciation, the evolutionary process of creating new species. Another possible explanation is the greater energy the tropics receive from the sun. But scientists have not been able to explain how greater energy input could translate into more species. The complexity of tropical ecosystems may promote speciation by increasing the habitat complexity, thus providing more ecological niches. Lastly, the tropics have been perceived as being more stable than temperate regions, which have a pronounced climate and day-length seasonality. The stability of tropical ecosystems might promote speciation. Regardless of the mechanisms, it is certainly true that biodiversity is greatest in the tropics. There are also high numbers of endemic species.
Why is it important to maintain the genetic diversity of wild species?
Loss of wild species related to a crop will mean the loss of potential in crop improvement. Maintaining the genetic diversity of wild species related to domesticated species ensures our continued supply of food.
How will species extinctions affect the world?
The loss of biodiversity will include many species we know today. Although it is sometimes difficult to predict which species will become extinct, many are listed as endangered (at great risk of extinction). However, many extinctions will affect species that biologist have not yet discovered. Most of these “invisible” species that will become extinct currently live in tropical rainforests like those of the Amazon basin. These rainforests are the most diverse ecosystems on the planet and are being destroyed rapidly by deforestation. Between 1970 and 2011, almost 20 percent of the Amazon rainforest was lost.
What is the loss of ecosystem diversity?
The loss of an ecosystem means the loss of the interactions between species and the loss of biological productivity that an ecosystem is able to create. An example of a largely extinct ecosystem in North America is the prairie ecosystem (Figure 2). Prairies once spanned central North America from the boreal forest in northern Canada down into Mexico. They are now all but gone, replaced by crop fields, pasture lands, and suburban sprawl. Many of the species survive, but the hugely productive ecosystem that was responsible for creating our most productive agricultural soils is now gone. As a consequence, their soils are now being depleted unless they are maintained artificially at great expense. The decline in soil productivity occurs because the interactions in the original ecosystem have been lost.
What is the study of the distribution of species?
Biogeography is the study of the distribution of the world’s species both in the past and in the present. The work of biogeographers is critical to understanding our physical environment, how the environment affects species, and how changes in environment impact the distribution of a species.
What is biodiversity loss?
Biodiversity loss refers to the reduction of biodiversity due to displacement or extinction of species. The loss of a particular individual species may seem unimportant to some, especially if it is not a charismatic species like the Bengal tiger or the bottlenose dolphin. However, the current accelerated extinction rate means the loss of tens of thousands of species within our lifetimes. Much of this loss is occurring in tropical rainforests like the one pictured in Figure 1, which are very high in biodiversity but are being cleared for timber and agriculture. This is likely to have dramatic effects on human welfare through the collapse of ecosystems.
How is biodiversity measured?
Traditionally, ecologists have measured biodiversity by taking into account both the number of species and the number of individuals of each species (known as relative abundance ). However, biologists are using different measures of biodiversity, including genetic diversity, to help focus efforts to preserve the biologically and technologically important elements of biodiversity.

Biodiversity can be explored in ...
How does human health affect biodiversity?
Scientists have learned a great deal about the regulating services of biodiversity by studying the human health impacts of ecosystem alteration and degradation (Myers et al. 2013). Human-made dams and irrigation projects have been linked to increases in vector-borne diseases such as malaria, leishmaniasis, and schistosomiasis (see Myers et al. 2013 for review). Deforestation and human encroachment into wildlife habitat have been associated with the emergence of several zoonotic diseases, including HIV and ebola (Hahn et al. 2000; Ostfeld 2009). Direct correlations between increased incidence of several infectious diseases, including Lyme, Chagas’, West Nile virus, and hantavirus, and decreasing mammalian or avian species diversity also demonstrate the pro tective, regulating service of biodiversity (see Ostfeld and Keesing 2012 for review).
How does biodiversity affect the environment?
Biodiversity influences how disease occurs in an individual or population, how the local climate is able to support life, and how resilient an area will be against flooding or a catastrophic storm. Regulating services are the processes that renew resources and ensure a functional, habitable environment.

In this article we examine four ways in which ...
What are the benefits of biodiversity?
Biodiversity and ecosystems produce a rich array of benefits that people depend on, including fisheries, drinking water, fertile soils for growing crops, climate regulation, inspiration, and aesthetic and cultural values. 2.
How do forests help the ecosystem?
Forests provide the important ecosystem service of absorbing carbon dioxide from the atmosphere and storing it. Forests are the largest component of the U.S. carbon sink, but growth rates of forests vary widely across the country. Well-watered forests of the Pacific Coast and Southeast absorb considerably more than the arid Southwestern forests or the colder Northeastern forests. Climate change and disturbance rates, combined with current societal trends regarding land use and forest management, are projected to reduce forest CO 2 uptake in the coming decades. Figure shows forest growth as measured by net primary production in tons of carbon per hectare per year, and are averages from 2000 to 2006 (Figure source: adapted from Running et al. 2004#N#5#N#).
How does biogeochemical change affect biodiversity?
Altered biogeochemical cycles together with climate change increase the vulnerability of biodiversity, food security, human health , and water quality to changing climate. However, natural and managed shifts in major biogeochemical cycles can help limit rates of climate change.
How has human activity increased carbon dioxide?
Human activities have increased atmospheric carbon dioxide by about 40% over pre-industrial levels and more than doubled the amount of nitrogen available to ecosystems. Similar trends have been observed for phosphorus and other elements, and these changes have major consequences for biogeochemical cycles and climate change.
How do land use and agriculture affect the environment?
In addition to direct impacts on ecosystems, societal choices about land use and agricultural practices affect the cycling of carbon, nitrogen, phosphorus, sulfur, and other elements, which also influence climate. These choices can affect, positively or negatively, the rate and magnitude of climate change and the vulnerabilities of human and natural systems.
Why do trees need longer summers?
Warmer winters allow more insects to survive the cold season, and a longer summer allows some insects to complete two life cycles in a year instead of one. Drought stress reduces trees’ ability to defend against boring insects. Above, beetle-killed trees in Rocky Mountain National Park in Colorado.
What are the services that forests provide?
Forests absorb carbon dioxide and provide many other ecosystem services, such as purifying water and providing recreational opportunities.
