rl_species_latest: Species latest assessment

Description

Get the latest assessment for a particular species (i.e., Latin binomial) or subspecies/variety/subpopulation (i.e., Latin trinomial). Wraps rl_species() and rl_assessment().

Usage

rl_species_latest(
  genus,
  species,
  infra = NULL,
  subpopulation = NULL,
  key = NULL,
  parse = TRUE,
  ...
)

Value

A list unless using a function with a trailing underscore, in which case json as character string is returned.

Arguments

genus

(character) The genus name of the species to look up.

species

(character) The species epithet of the species to look up.

infra

(character) An optional name of the subspecies or variety to look up.

subpopulation

(character) An optional name of the geographically separate subpopulation to look up.

key

(character) An IUCN API token. See rl_use_iucn().

parse

(logical) Whether to parse the output to list (FALSE) or, where possible, data.frame (TRUE). Default: TRUE.

...

Includes the following arguments related to the wait time between request retries if a "Too Many Requests" error is received from the API (see HttpClient()$retry() for more details):

• pause_base, pause_cap, and pause_min: basis, maximum, and minimum for calculating wait time for retry

• times: the maximum number of times to retry

• onwait: a callback function if the request will be retried and a wait time is being applied

Also supports any curl options passed to the GET request via HttpClient.

Details

Geographically separate subpopulations of a species are defined as those populations that are so isolated from others of the same species that it is considered extremely unlikely that there is any genetic interchange. In general, listings of such subpopulations are restricted to those that have been isolated for a long period of time.

Assessments of subspecies, varieties, and geographically separate subpopulations must adhere to the same standards as for species assessments. However, these assessments are only included provided there is a global assessment of the species as a whole.

Infraspecific ranks such as formas, subvarieties, cultivars, etc are not included in the Red List.
