What are the most important value of biodiversity and importance of high and low biodiversity?
Ecosystems with high biodiversity can recover from disturbances better than ecosystems with low biodiversity. This means healthy ecosystems are more likely to continue to support humans even as the earth goes through extreme changes. The biggest impact of biodiversity is on the environment. Healthy ecosystems help to maintain the Earth's natural processes. Soil turnover, water purification, pest control, and other processes wouldn't be possible without the species that support them
Repecfully, this could not be more wrong. Biodiversity is at the mercy of the environment. End-Permian and End-Cretaceous extinctions (the loss of diversity), for example, are a direct consequence of radically changed environment. And the diversification of species subsequently is a result of niche filling in the new environment by the desendents of the few species that survived the catastrophe.
Environmental and ecological value, social value, ecosystem services, economic and financial value, consumptive utility value, productive usage value, moral and ethical value, and aesthetic value are some of the most significant values of biodiversity.
In the general theory, more species diversity results in a more stable ecosystem. This idea is referred to as the "diversity-stability hypothesis." In comparison to an ecosystem of equal size with fewer species, one with more species has a higher likelihood of withstanding a disturbance.
However, in practise, biodiversity plays different roles in various ecosystems and throughout different time periods. Humans, ecological succession, latitude, and a wide range of other elements all have an impact on this relationship, which is quite complex. Since invasive species can take advantage of the vacant niches, damaged landscapes frequently have high biodiversity levels. As time passes and succession takes place, however, many of these species do not maintain robust populations. The landscape will most likely be less diverse but more natural and representational of the original ecosystem as a result of succession, time, and recovery from the disturbance.
Biodiversity is the basically shaped by the environmental conditions along geological periods of time, in which species adapt and evolve to conform characteristic ecological communities. If we compare, for example, biological communities of a desert with those of a rain forest in the tropics, it would be clear the difference in the number of inhabiting species adapted to the specific conditions of those places. In either place, the species represent an element that perform specific ecological roles that maintain ecological processes running. From my personal point of view, the value and importance of biodiversity is paramount in every place as the basis of the continuity of life, as well as the maintenance of the processes on which life depends on. High or low biodiversity are equally important in that sense.
The biodiversity of species, or species richness, is often used as a measure of ecological health. High biodiversity, with many species present, is good. It usually means that an ecosystem is healthy and relatively undisturbed by humans. Low biodiversity is characteristic of an unhealthy or degraded environment. Greater species 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. The biggest impact of biodiversity is on the environment. Healthy ecosystems help to maintain the Earth's natural processes. Soil turnover, water purification, pest control, and other processes wouldn't be possible without the species that support them.Without biodiversity, our entire support system for human, as well as animal life, would collapse. We rely on nature to provide us with food and clean water, for a lot of medicines, and to prevent flooding and other extreme weather effects. Ecosystems with high biodiversity can recover from disturbances better than ecosystems with low biodiversity. This means healthy ecosystems are more likely to continue to support humans even as the earth goes through extreme changes.
Greater biodiversity means greater ecosystem stability and lower biodiversity means less stability. Over time, greater stability means greater perseverance of an ecosystem.
Biodiversity maintains the ecological balance. It helps in the healthy existence of humans and other species in the ecosystem. It helps in high productivity and human wellness. Biodiversity provides humans with valuable genetic diversity. Without biodiversity, our entire support system for human, as well as animal life would collapse. We rely on nature to provide us with food and clean water, for a lot of medicines, and to prevent flooding and other extreme weather effects. High biodiversity is advantageous over low biodiversity because ecosystems with high biodiversity are better able to remain at homeostasis and be productive. When biodiversity is high, there is a large number of different species. Greater biodiversity in ecosystems, species, and individuals leads to greater stability. As 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. Higher biodiversity leads to a more stable ecosystem. However, there are contradictory opinions on the subject. Different factors may lead to stability loss. The very same factors almost always also cause loss of species diversity. Tropical regions, areas that are warm year-round, have the most biodiversity. Temperate regions, which have warm summers and cold winters, have less biodiversity. Regions with cold or dry conditions, such as mountaintops and deserts, have even less. Coral reefs are believed by many to have the highest biodiversity of any ecosystem on the planet even more than a tropical rainforest. Occupying less than one percent of the ocean floor, coral reefs are home to more than 25% of all marine life. Healthy ecosystems help to maintain the Earth's natural processes. Soil turnover, water purification, pest control, and other processes wouldn't be possible without the species that support them.
The function of ecosystems depends on biodiversity, which also benefits humans in many ways. Low biodiversity may harm ecosystem functioning and human well-being, whereas high biodiversity increases ecosystem resilience to environmental change. Action must be taken to lessen soil pollution and safeguard soil biodiversity because soil pollution poses a serious threat to biodiversity and ecological health. Also, biodiversity's contribution to preserving ecosystem services is one of its most significant values. The advantages to humans due to natural ecosystems include clean air and water, crop pollination, and climate regulation. Because various species play various roles in ecosystem function, biodiversity is crucial for providing these services. For instance, plants are necessary for synthesising oxygen and storing carbon dioxide, whereas insects are essential for pollination and decomposition.
Generally speaking, greater species 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. The biodiversity of species, or species richness, is often used as a measure of ecological health. High biodiversity, with many species present, is good.

Biodiversity refers to the number of biological species that exist in a given region. High biodiversity means that a region supports a wide variety of species, while low biodiversity implies that an area supports only a few. Tropical regions, areas that are warm year-round, have the most biodiversity. Temperate regions, which have warm summers and cold winters, have less biodiversity. Regions with cold or dry conditions, such as mountaintops and deserts, have even less. Biodiversity, or the variety of all living things on our planet, has been declining at an alarming rate in recent years, mainly due to human activities, such as land use changes, pollution and climate change.
Rk Naresh gave a rather detailed answer to this question. However, I would like to add that species diversity is an indicator of favorable environmental conditions. The higher the corresponding indicators of species diversity, the more favorable envirRk Nareshonmental conditions. Having reference indicators of species diversity for a certain biotope of a particular territory, we can judge the transformation of the state of the ecosystem over the past period. Thus, by species diversity, we can judge the degree of transformation (biotope, ecosystems) over a certain period under the influence of both anthropogenic factors and natural causes (climate change, favorable environmental conditions)
If you are interested, we offer an index for assessing the state and transformation of Holocene ecosystems based on the species diversity of small mammals. Here is a link to these works:
Rk Naresh дал довольно детальный ответ на этот вопрос. Однако, хотелось добавить, что видовое разнообразие является показателем благоприятности условий среды. Чем выше соответствующие показатели видового разнообразия, тем благоприятнее условия среды. Имея эталонные показатели видового разнообразия для определенного биотопа конкретной территории, мы можем судить о трансформации состояния экосистемы за истекший период. Таким образом, по видовому разнообразию мы можем судить о степени трансформации (биотопа, экосистемы) за определенный период под воздействием как антропогенного фактора, так и естественных причин (изменение климата, условий благоприятности среды).
Если интересно - нами предлагается индекс оценки состояния и трансформации экосистем голоцена по видовому разнообразию мелких млекопитающих.
