Taxonomic databases digitize scientific biodiversity data and provide access to taxonomic data for research. [1] Taxonomic databases vary in breadth of the groups of taxa and geographical space they seek to include, for example: beetles in a defined region, mammals globally, or all described taxa in the tree of life.

It overcomes the shortcomings of biodiversity indices that cannot display the relative role different variables played in their calculation. The curve is a 2D chart with relative abundance on the Y-axis and the abundance rank on the X-axis. X-axis: The abundance rank. The most abundant species is given rank 1, the second most abundant is 2 and ...
DNA barcoding is a method of species identification using a short section of DNA from a specific gene or genes. The premise of DNA barcoding is that by comparison with a reference library of such DNA sections (also called "sequences"), an individual sequence can be used to uniquely identify an organism to species, just as a supermarket scanner uses the familiar black stripes of the UPC barcode ...
This is a list of biodiversity databases. Biodiversity databases store taxonomic information alone or more commonly also other information like distribution (spatial) data and ecological data, which provide information on the biodiversity of a particular area or group of living organisms. They may store specimen-level information, species-level ...
Furthermore, morphological identification depends directly on taxonomic expertise, which is in decline. [89] [90] [91] All such limitations of traditional biodiversity monitoring have created a demand for alternative approaches.
Biodiversity is usually plotted as the richness of a geographic area, with some reference to a temporal scale. Types of biodiversity include taxonomic or species, ecological, morphological, and genetic diversity. Taxonomic diversity, that is the number of species, genera, family is the most commonly assessed type. [7]
Metabarcoding is the barcoding of DNA/RNA (or eDNA/eRNA) in a manner that allows for the simultaneous identification of many taxa within the same sample. The main difference between barcoding and metabarcoding is that metabarcoding does not focus on one specific organism, but instead aims to determine species composition within a sample.
A combination ATBI and BioBlitz, this effort was the result of a collaboration between the E.O. Wilson Biodiversity Foundation, the National Park Service, Discover Life in America, and the Turner Endangered Species fund to deploy graduate student "Bioblitz SWAT Teams" to determine and fill in major gaps in biodiversity research.
