ecological importance of biodiversity

Jan 30, 2012 . The current rate of extinction is … Describing species is a complex process by which biologists determine an organism’s unique characteristics and whether or not that organism belongs to any other described species. We’d miss their leafy shade, fall colours and maple syrup. Another possible explanation is the greater energy the tropics receive from the sun. For example, the richness of diversity allows medicines and foods to be naturally available. These wetlands are of huge importance for other species/groups such as otter and water vole, waterfowl, great crested newt and a large array of insects, fish and plants. The loss of the crop led to famine, death, and mass emigration. One example of this is Kenya’s Lake Turkana — the world’s largest desert lake, a habitat for a variety of wildlife carriers like mosquitoes to extend their geographic ranges and infect new populations of humans. Furthermore, biodiversity research has demonstrated that plant diversity enhances the productivity and functioning of ecosystems. These rainforests are the most diverse ecosystems on the planet and are being destroyed rapidly by deforestation. The world’s growing human population faces significant challenges in the increasing costs and other difficulties associated with producing food. All major religions include elements of nature and 231 species are Loss of diversity in pest enemies will inevitably make it more difficult and costly to grow food. They are now all but gone, replaced by crop fields, pasture lands, and suburban sprawl. 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. Protecting biodiversity plays a crucial part in achieving these emissions reductions. is no likely ecological impact. The stability of tropical ecosystems might promote speciation. For example, the COVID-19 pandemic can likely be sourced to a wild animal and fish market in Wuhan, China. However, many extinctions will affect species that biologist have not yet discovered. Biogeography is the study of the distribution of the world’s species both in the past and in the present. ECOLOGICAL AND ECONOMICAL IMPORTANCE OF BIODIVERSITY Biodiversity is considered a cornerstone to the health of the environment. The destruction of forest ecosystems is responsible for 11 percent of all global greenhouse gas emissions caused by humans, so conserving forests would stop the release of these gases into the atmosphere. For example, a forest with 10 equally common species of trees is more diverse than a forest that has 10 species of trees wherein just one of those species makes up 95 percent of the trees. The concept of biodiversity is an integral part of many human cultures. The ultimate outcome could clearly be the loss of aquatic systems as food sources.

Seventy percent of emerging viral diseases have spread from animals to humans. Species are frequently integral to religious, cultural and national identities. is the study of the distribution of the world’s species both in the past and in the present. This is one measure of the bird biodiversity on the continent. They occur within ecosystems, such as soil ecosystems, as a result of the diverse metabolic activities of the organisms living there, but they provide benefits to human food production, drinking water availability, and breathable air. Although some agricultural soils are rendered sterile using controversial pesticide treatments, most contain a huge diversity of organisms that maintain nutrient cycles—breaking down organic matter into nutrient compounds that crops need for growth. Another experimental study found that introducing multiple enemies of pea aphids (an important alfalfa pest) increased the yield of alfalfa significantly. Despite considerable effort, knowledge of the species that inhabit the planet is limited. An example of a largely extinct ecosystem in North America is the prairie ecosystem (Figure 2). Lake Huron contains about 79 species of fish, all of which are found in many other lakes in North America. Since the 1920s, government agriculture departments have maintained seed banks of crop varieties as a way to maintain crop diversity. Recreation—many recreational pursuits rely on our unique biodiversity, such as birdwatching, hiking, camping and fishing. discovered that nature can deliver at least 30 percent of the emissions reductions needed by 2030 to prevent climate catastrophe. A recent estimate suggests that only 13% of eukaryotic species have been named (Table 1). Many honeybee populations are managed by beekeepers who rent out their hives’ services to farmers. 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. source of inspiration for artists and designers.

These same seed companies, however, have participated in the decline of the number of varieties available as they focus on selling fewer varieties in more areas of the world replacing traditional local varieties. Protecting the nature we all rely on for food, fresh water and livelihoods. Examples of significant medicines derived from plant compounds include aspirin, codeine, digoxin, atropine, and vincristine (Figure 4). Regardless of the mechanisms, it is certainly true that biodiversity is greatest in the tropics. Given that Earth is losing species at an accelerating pace, science knows little about what is being lost. These booms in biodiversity are all thanks to beavers. Lastly, the tropics have been perceived as being more stable than temperate regions, which have a pronounced climate and day-length seasonality. With COVID-19, we’ve seen the damage that diseases can do not only to human health, but also to the global economy. Biodiversity loss refers to the reduction of  biodiversity due to displacement or extinction of species. 2018 Jan;2(1):57-64. doi: 10.1038/s41559-017-0402-5. The people in this region traditionally lived in relatively isolated settlements separated by mountains. Over 150 crops in the United States require pollination to produce. A challenge in implementing biodiversity conservation is in reconciling criteria for identifying significant areas and representative networks for biodiversity protection. In addition to growing crops and raising food animals, humans obtain food resources from wild populations, primarily wild fish populations. Lake Victoria contained almost 500 species of cichlids (just one family of fishes that are present in the lake) before the introduction of an exotic species in the 1980s and 1990s caused a mass extinction. In a landmark study published in 2017, a group of researchers led by Bronson Griscom, who researches natural climate solutions at Conservation International,
