How do you analyze biodiversity?
Scientists use several methods to measure biodiversity. These include canopy fogging, quadrat sampling, transect sampling, and netting. The method used depends on the types of organisms ecologists are counting and on the habitat.
What is the biodiversity of India?
India displays significant biodiversity. One of seventeen megadiverse countries, it is home to 7.6% of all mammalian, 12.6% of all avian, 6.2% of all reptilian, 4.4% of all amphibian, 11.7% of all fish, and 6.0% of all flowering plant species.
What is biodiversity explain the biodiversity in India?
Biodiversity is the variety and differences among living organisms from all sources, including terrestrial, marine, and other aquatic ecosystems and the ecological complexes of which they are a part. The Thar desert and the Himalayas are two regions rich in biodiversity in India.
What makes Indian biodiversity unique?
India has tremendous biodiversity, genetic as well as of species and ecosystems. It contains over 7 per cent of the world’s biodiversity on 2.5 per cent of the Earth’s surface. Among amphibians found in India, 62% are unique to this country. Among lizards, of the 153 species recorded, 50% are endemic.
What is Shannon’s index?
A diversity index is a quantitative measure that reflects how many different types (such as species) there are in a dataset (a community), and that can simultaneously take into account the phylogenetic relations among the individuals distributed among those types, such as richness, divergence or evenness.
What are types of biodiversity?
Usually three levels of biodiversity are discussed—genetic, species, and ecosystem diversity.
What is the rank of India in biodiversity?
India ranks fourth in Asia and tenth in the world in plant diversity, the Birsa Agricultural University (BAU) Vice Chancellor, N N Singh, has said. “India boasts of 45,000 plants and 91,000 animal species,” Singh said delivering a special lecture on Agro-biodiversity and farmers’ rights at BAU Saturday.
What is biodiversity example?
Biodiversity is the variety of life. Most people recognize biodiversity by species—a group of individual living organisms that can interbreed. Examples of species include blue whales, white-tailed deer, white pine trees, sunflowers, and microscopic bacteria that can’t even be seen by the naked eye.
How is Shannon’s index calculated?
How to calculate the Shannon diversity index?
- Calculate the proportion (pi) of each species – divide the number of individuals in a species by the total number of individuals in the community.
- For each species, multiply the proportion by the logarithm of the proportion.
- Sum all the numbers from step 2.
What are 4 types of biodiversity?
Four Types of Biodiversity
- Species Diversity. Every ecosystem contains a unique collection of species, all interacting with each other.
- Genetic Diversity. Genetic diversity describes how closely related the members of one species are in a given ecosystem.
- Ecosystem Diversity.
- Functional Diversity.
Why did India pass the Biological Diversity Act?
But India did not have a comprehensive law dealing with conservation of biodiversity until 2002, when the Biological Diversity Act was enacted, in order to ensure compliance with the Convention of Biological Diversity, 1992. Factors like pollution, overexploitation and degradation, coupled with natural causes, pose a threat to biodiversity.
Are there any laws to protect biodiversity in India?
However, the United Nations Convention on Biological Diversity for the first time made a comprehensive plan for the protection of biodiversity. Post 1990s, there was a change in the economic structure from closed economy to open economy. Thus, there were no laws to protect bio-piracy by the developed nation on the Indian soil.
Which is the most important biodiversity zone in India?
The Indian Desert Zone is another important biodiversity zone. It covers about 6.6 per cent of the total geographical area. It includes the Thar and the Kutc h deserts. 3B: Desert – Katchchh (1.1 %). viz., Houbara Bustard (Chamydotis undulate) and the Great Indian Bustard (Ardeotis nigriceps). 4.
What are the problems with the Biodiversity Act?
Factors like pollution, overexploitation and degradation, coupled with natural causes, pose a threat to biodiversity. Although the Act tries to deal with these problems, there are still loopholes like inadequate access to local communities, non-inclusion of genetic resources and access benefit sharing.
