A diversity index is a method of measuring how many different types (e.g. species) there are in a dataset (e.g. a community).Diversity indices are statistical representations of different aspects of biodiversity (e.g. richness, evenness, and dominance), which are useful simplifications for comparing different communities or sites.
Gnetum gnemon is a gymnosperm species of Gnetum, its native area spans from Mizoram and Assam in India down south through Malay Peninsula, Malay Archipelago and the Philippines in southeast Asia to the western Pacific islands. [3] Common names include gnetum, joint fir, two leaf, melinjo/belinjo , bago/lumbay , and tulip . [4]
The total amount of DNA base pairs on Earth, as a possible approximation of global biodiversity, is estimated at 5.0 x 10 37, and weighs 50 billion tonnes. [7] In comparison, the total mass of the biosphere has been estimated to be as much as 4 TtC (trillion tons of carbon). [8] In other related studies, around 1.9 million extant species are ...

[83] [84] 139 Upland cotton (Gossypium hirsutum) 52 This is for the cultivated species G. hirsutum (allotetraploid, 2n=4x=52). This species accounts for 90% of the world cotton production.
A megadiverse country is one of a group of nations that harbours the majority of Earth's species and high numbers of endemic species. Conservation International identified 17 megadiverse countries in 1998, [1] [2] all of which are located at least partially in tropical or subtropical regions. Megadiversity means exhibiting great biodiversity.
