Ecological diversity is the largest scale of biodiversity, and within each ecosystem, there is a great deal of both species and genetic diversity. [1] [2] [3] [4]
Species evenness is the relative number of individuals of each species in a given area. [181] Species richness [182] is the number of species present in a given area. Species diversity [183] is the relationship between species evenness and species richness. There are many ways to measure biodiversity within a given ecosystem.
This conservation scheme was designed to benefit those local communities which neighbour Indonesian forestry and to help the most endangered species living in these threatened habitats. Prior to 2015, it was named Directorate General of Forest Protection and Nature Conservation ( Direktorat Jenderal Perlindungan Hutan dan Konservasi Alam - PHKA ).
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.
Insects make up the vast majority of animal species. [14]Chapman, 2005 and 2009 [9] has attempted to compile perhaps the most comprehensive recent statistics on numbers of extant species, drawing on a range of published and unpublished sources, and has come up with a figure of approximately 1.9 million estimated described taxa, as against possibly a total of between 11 and 12 million ...
Indomalaya has 1000 species of amphibians in 81 genera, about 17 of global species. 800 Indomalayan species, or 80%, are endemic. Indomalaya has three endemic families of amphibians, Nasikabatrachidae , Ichthyophiidae , and Uraeotyphlidae . 329, or 33%, of Indomalayan amphibians are considered threatened or extinct, with habitat loss as the ...
Environmental issues due to Indonesia's rapid industrialisation process and high population growth, have seen lower priority given to preserving ecosystems. [3] Issues include illegal logging, with resulting deforestation, and a high level of urbanisation, air pollution, garbage management and waste water services also contributing to the forest deterioration.
One of the recent new species discovered in Borneo is the lungless frog, which can fly. The high level of biodiversity will be formed if there is a small variation in environmental conditions and a moderate amount of disturbance. A stable condition is favored by species if compared to unstable condition.
