Rotifers and environmental variables on TDWG level 4 regions of the world
Description
These data were extracted from a database of monogonont rotifer species presence records on the geographical units used by the Biodiversity Information Standards (formerly Taxonomic Database Working Group, TDWG: https://www.tdwg.org) and a few environmental (including human and spatial) variables on the same spatial units. The original data were compiled and published by Fontaneto et al. (2012) in long (narrow, stacked) format. Here they are presented in wide or unstacked format (presence-absence table, obtained with the splist2presabs function), reduced to the species recorded in at least 100 (roughly one third) different TDWG level 4 units, and with abbreviations of the species' names (obtained with the spCodes function). Mind that this is not a complete picture of these species' distributions, due to insufficient sampling in many regions.
