rotifers: Rotifer species on TDWG level 4 regions of the world

In fuzzySim: Fuzzy Similarity in Species Distributions

Rotifer species on TDWG level 4 regions of the world

Description

These data were extracted from a database of monogonont rotifer species records on the geographical units used by the Biodiversity Information Standards (formerly Taxonomic Database Working Group, TDWG: https://www.tdwg.org). The original data were compiled and published by Fontaneto et al. (2012) for all TDWG levels. Here they are reduced to the TDWG - level 4 units and to the species recorded in at least 100 (roughly one third) of these units. Mind that this is not a complete picture of these species' distributions, due to insufficient sampling in many regions.

Usage

data("rotifers")

Format

A data frame with 3865 observations on the following 2 variables.

TDWG4

a factor with 274 levels corresponding to the code names of the TDWG level 4 regions in which the records were taken

species

a factor with 30 levels corresponding to the names of the (sub)species recorded in at least 100 different TDWG level 4 regions
