Species richness per geographic region and taxonomic group in GIFT

Description

Retrieve species richness of all species, native species, naturalized species and endemic species per taxonomic group and geographic region combination.

Usage

GIFT_richness(
  taxon_name = "Embryophyta",
  GIFT_version = "latest",
  api = "https://gift.uni-goettingen.de/api/extended/"
)

Arguments

taxon_name	Taxonomic group to retrieve species richness for.
GIFT_version	character string defining the version of the GIFT database to use. The function retrieves by default the latest stable version. If set to beta, the most up-to-date version which is still subject to changes and edits is used.
api	character string defining from which API the data will be retrieved.

Details

The output has 5 columns:

entity_ID - Identification number of the geographic region
total - total species richness
native - number of native species
naturalized - number of naturalized species
endemic_min - number of endemic species

The number of endemic species is a conservative count not counting occurrences of species which go back to infraspecific taxa.

Value

A data frame with species richness values for different floristic subsets per geographic region in GIFT.
