Biodiversity can be measured at many different levels including genetic, species, community, and ecosystem. The American Revolution (1775–83) won political independence for 13 of Britain’s North American colonies, which subsequently formed the United States of America. Biodiversity can be considered in THREE levels, (1). Our natural-history museums, for example, contain at least 750 million specimens, the vast majority of which have not been recorded in databases. Ø  Biodiversity provides: fuel, timber, fish, fodder, fruits, honey, cereals, medicinal plants etc. Population diversity: variations observed quantitative ecological parameters such as frequency, density, abundance etc. Biodiversity is defined as the variability among living organisms from all sources including, inter alia, terrestrial, marine and other aquatic ecosystems and the ecological complexes of which they are part; this includes diversity within species, between species and of ecosystems. Ø  Uses related to biodiversity can be grouped into three categories: (adsbygoogle=window.adsbygoogle||[]).push({}), Ø  Products commercially harvested from biodiversity for exchange in market, Ø  Productive value of biodiversity is concerned with national income. Ecosystem diversity: deals with the variations of interdependence of biotic and abiotic factors in the ecosystem, (7). Biologists, however, always alert to levels of organization, have identified three measures of life’s variation. Endemic species are restricted to one location; they do not occur anywhere else in the world. Please Share with Your Friends... Look deep into nature, and then you will understand everything better’, Threats to Biodiversity: Simple Lecture Notes. However, species richness is a measure used to describe biodiversity. However, biodiversity may be measured in other ways. Beta diversity is low if same species of moss occupy the whole mountain side (3). The total volume of biodiversity and ecosystem information is almost impossible to measure. As a consequence, generally accepted biodiversity measurement approaches for application by the business and financial community are not yet available at the product, project, site, supply chain, corporate or sector level. We do know that whatever the total, only a fraction has been captured in digital form. A very good way to measure biodiversity would be to do environmental barcoding with high-throughput sequencing methods, and then use an algorithm that estimates genetic distance to get both species count estimates, and then calculate higher-level diversity, such as genera and families. Hii Tanisha , Biodiversity is usually plotted as taxonomic richness of a geographic area, with some reference to a temporal scale. Enter your e-mail address. Biodiversity indices Species richness indices. Ø  In India, income from biodiversity is nearly 30% (736.88 billion rupees, 1994-95), Ø  Consumptive use of biodiversity deals with natural products that are consumed directly, Ø  They are goods which do not come under normal circulation of trade, Ø  Example: non timber forest products, Honey collected from forests, Medicine collected from forests, Ø  Indict use is the most significant us of biodiversity, Ø  This value is related primarily with functions of ecosystem, Ø  Biodiversity is very essential for: Ecological balance, Constancy of climatic features and Soil maintenance, Ø  Biodiversity indicates variations of life forms (species, ecosystem, biome), Ø  Biodiversity indicate the health of ecosystem, Ø  Biodiversity is in part a functioning of climate, Ø  Biodiversity provides services like: Air quality and purity, Climate and seasons, Water purification, Pollination and seed dispersal, Prevention of erosion, Ø  Non material benefits of biodiversity are: Spiritual values, Aesthetic values, Education and knowledge systems, Ø  In agriculture biodiversity assist in the recovery of major cultivar when it is under sever attack of disease or pests, Ø  Biodiversity also act as a store house of germplasm of commercially important plants, Ø  About 80% of humans’ food supply comes from 20 kinds of plants, but human uses at least 40,000 species, all of them are the part of biodiversity, Ø  There are more plant products to be discovered from diversity, they are kept hidden in the depth of species richness, Ø  Biodiversity also support in drug discovery for modern diseases, Ø  Most of the drugs which are now in commercial trade are derived directly or  indirectly from biological resources, Ø  About 50% of drugs used in US are derived from biodiversity, Ø  According to WHO, 80% of world population depends on medicines from nature (biodiversity is the integral part of nature), Ø  Many industrial materials are deriving from biological sources.
