Regional biodiversity includes habitats and ecosystems that synergizes and either overlaps or differs on a regional scale. National biodiversity within a country determines the ability for a country to thrive according to its habitats and ecosystems on a national scale.
Ecosystem diversity addresses the combined characteristics of biotic properties which are living organisms (biodiversity) and abiotic properties such as nonliving things like water or soil (geodiversity). It is a variation in the ecosystems found in a region or the variation in ecosystems over the whole planet.
Global biodiversity is the measure of biodiversity on planet Earth and is defined as the total variability of life forms. More than 99 percent of all species [ 1 ] that ever lived on Earth are estimated to be extinct .
A number of factors within the forest affect biodiversity; primary factors enhancing wildlife abundance and biodiversity was the presence of diverse tree species within the forest and the absence of even aged timber management. [12]
With 23.39% of its geographical area under forest and tree cover, India is rich in biodiversity. A 2020 faunal survey of India by the Zoological Survey of India (ZSI) reported a total of 102,718 species of fauna, with 557 new species including 407 newly described species and 150 new country records. Among the new finds, 486 species were ...
Biodiversity hotspots include the Himalayas, the Western Ghats, the Indo-Burma region [9] and the Sundaland. India has set up its first gene sanctuary in the Garo Hills of Meghalaya for wild relatives of citrus. Efforts are also being made to set up gene sanctuaries for banana, sugarcane, rice and mango.
Biodiversity plays a major role in the productivity and functioning of ecosystems, affects their ability to provide ecosystem services. [2] For example, biodiversity is a source of food, medication, and materials used in industry. Recreation and tourism are also examples of human economic activities that rely on these benefits.
Relative species abundance is a component of biodiversity and is a measure of how common or rare a species is relative to other species in a defined location or community. [1] Relative abundance is the percent composition of an organism of a particular kind relative to the total number of organisms in the area.
