Add earthworm traits (Pelosi et al. 2014) — add_betsi_earthworm

Joins fuzzy-coded earthworm functional traits to a taxify() result by looking up accepted_name. Output columns are prefixed betsi_ew_.

Usage

add_betsi_earthworm_traits(x, cols = NULL, verbose = TRUE)

Arguments

x: A data.frame returned by taxify().
cols: Which columns to attach: NULL (default) all, or a character vector of names. See enrichment_cols.
verbose: Logical. Default TRUE.

Value

The same data.frame with additional columns, one per modality bin of seven fuzzy-coded traits: body length, body mass to length ratio, cocoon diameter, epithelium, typhlosolis, soil carbon preference and vertical distribution. Each trait is fuzzy coded, so a species' affinities across the bins of one trait (columns sharing a betsi_ew_<trait>__ stem) sum to 100. See enrichment_cols for the full column list.

Details

Source: earthworm functional traits compiled from the BETSI database (Biological and Ecological Traits of Soil Invertebrates) and published in Pelosi et al. (2014), Appendix 1. Coverage: 11 species. Earthworm body length and soil carbon preference are given as fuzzy affinity vectors rather than a single value, so they are not passed to the scalar add_trait() verb.
