While there is no commonly used database, there are comprehensive databases such as the Catalogue of Life, which attempts to list every documented species. [101] The catalogue listed 1.64 million species for all kingdoms as of April 2016, claiming coverage of more than three-quarters of the estimated species known to modern science. [102]
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 ).
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.
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perhaps the most comprehensive recent statistics on numbers of extant species, drawing on a range of published and unpublished sources, and has come up with a figure of approximately 1.9 million estimated described taxa, as against possibly a total of between 11 and 12 million ...
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.
The hierarchy of biological classification's eight major taxonomic ranks. A genus contains one or more species. Minor intermediate ranks are not shown. A species (pl.: species) is a population of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. [1]
There are currently 1,258 genera, 161 families, 27 orders, and around 5,937 recognized living species of mammal. [1] Mammalian taxonomy is in constant flux as many new species are described and recategorized within their respective genera and families.
