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 data accessible and searchable through a ...

On Earth, it is found mostly in oceans and other large bodies of water, with 1.6% of water below ground in aquifers and 0.001% in the air as vapor, clouds, and precipitation. [ 32 ] [ 33 ] Oceans hold 97% of surface water, glaciers , and polar ice caps 2.4%, and other land surface water such as rivers, lakes, and ponds 0.6%.
The databases in the table below are selected from the databases listed in the Nucleic Acids Research (NAR) databases issues and database collection and the databases cross-referenced in the UniProtKB. Most of these databases are cross-referenced with UniProt / UniProtKB so that identifiers can be mapped to each other. [15] Proteins in human:
Weather is a set of all the phenomena occurring in a given atmospheric area at a given time. [26] Most weather phenomena occur in the troposphere , [ 27 ] [ 28 ] just below the stratosphere . Weather refers, generally, to day-to-day temperature and precipitation activity, whereas climate is the term for the average atmospheric conditions over ...
[2] The most common form of free-energy relationships are linear free-energy relationships (LFER). The Brønsted catalysis equation describes the relationship between the ionization constant of a series of catalysts and the reaction rate constant for a reaction on which the catalyst operates.
Species evenness is the relative number of individuals of each species in a given area. [1] Species richness [2] is the number of species present in a given area. Species diversity [3] is the relationship between species evenness and species richness. There are many ways to measure biodiversity within a given ecosystem.
The economic activity of pollination alone represented between $2.1–14.6 billion in 2003. [143] Other sources have reported somewhat conflicting results and in 1997 Robert Costanza and his colleagues reported the estimated global value of ecosystem services (not captured in traditional markets) at an average of $33 trillion annually.
