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. [2][3] Estimates on the number of Earth's current species range from 2 million to 1 trillion, but most estimates are around 11 ...
Essential Biodiversity Variables (EBVs) is a putative set of parameters intended to be the minimum set of broadly agreed upon necessary and sufficient biodiversity variables for at least national to global monitoring, researching, and forecasting of biodiversity. [1] They are being developed by an interdisciplinary group of governmental and ...
The Global Assessment Report is a global-level assessment of changes in Earth's biodiversity that have occurred over the past 50 years. It draws an extensive picture of economic development and its effects on nature in that period. The Report is a collaborative effort by 145 authors from 50 countries, [8] produced over a three-year period and ...
Map: Participant nations as of 15 June 2020. The Global Biodiversity Information Facility (GBIF) is an international organisation that focuses on making scientific data on biodiversity available via the Internet using web services. [1] The data are provided by many institutions from around the world; GBIF's information architecture makes these ...
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is an inventory of the global conservation status and extinction risk of biological species. [1] A series of Regional Red Lists, which assess the risk of extinction to species within a ...
The Living Planet Index (LPI) is an indicator of the state of global biological diversity, based on trends in vertebrate populations of species from around the world. The Zoological Society of London (ZSL) manages the index in cooperation with the World Wide Fund for Nature (WWF). As of 2022, the index is statistically created from journal ...
Avibase is an extensive database information system about all birds of the world, containing over 27 million records about 10,000 species and 22,000 subspecies of birds, including distribution information for 20,000 regions, taxonomy, synonyms in several languages and more. ASEAN Biodiversity Information Sharing Service (BISS) [5] Amphibians ...
Biodiversity is commonly measured in terms of taxonomic richness of a geographic area over a time interval. In order to calculate biodiversity, species evenness, species richness, and species diversity are to be obtained first. Species evenness[1] is the relative number of individuals of each species in a given area.
