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.
Diversity in the ecosystem is significant to human existence for a variety of reasons. Ecosystem diversity boosts the availability of oxygen via the process of photosynthesis amongst plant organisms domiciled in the habitat.
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 ).
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perhaps the most comprehensive recent statistics on numbers of extant species, drawing on a range of published and unpublished sources, and has come up with a figure of approximately 1.9 million estimated described taxa, as against possibly a total of between 11 and 12 million ...
Red list categories of the IUCN Demonstrator against biodiversity loss, at Extinction Rebellion (2018).. The current rate of global biodiversity loss is estimated to be 100 to 1000 times higher than the (naturally occurring) background extinction rate, faster than at any other time in human history, [25] [26] and is expected to grow in the upcoming years.
Other ape species include the white-handed gibbon and the siamang. [1] Malaysia has 10 monkey species, divided between langurs and macaques. [5] Proboscis monkeys, the world's largest monkey, [1] are a langur species endemic to Borneo. [5] Macaque species include the crab-eating macaque and the pig-tailed macaque. [1]
It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partnerships. The organization is best known to the wider public for compiling and publishing the IUCN Red List of Threatened Species, which assesses the conservation status of species worldwide. [4]
Borneo has own a wide variety of bird species. The geological history of Borneo is a major factor: long isolation of the island, broken during the last Ice age, when Borneo was connected to the continent of Asia, led to a combination of Asian and native species. There are about 420 species of birds and 37 are endemic to Borneo [4] [5]
