Add Italian plant traits from Pignatti (on demand, via TR8)

Fetches Italian Ellenberg-type indicator values, life form, and chorotype from Pignatti's Flora d'Italia (Pignatti, Menegoni & Pietrosanti 2005) for the species in a taxify() result, using the TR8 package, and joins them by accepted_name. TR8 ships these values bundled, so this works offline.

Usage

add_pignatti(x, verbose = TRUE)

Arguments

x

A data.frame returned by taxify().

verbose

Logical. Default TRUE.

Value

The same data.frame with additional columns:

light_it, temperature_it, continentality_it, moisture_it, reaction_it, nutrients_it, salinity_it

Ellenberg-type indicator values calibrated for the Italian flora (codes; X = indifferent, 0 = not applicable).

life_form_it

Life form for the Italian flora.

chorotype_it

Chorological type (distribution).

Details

These values originate in a copyrighted publication, so taxify does not redistribute them. This function reads the copy bundled in the suggested package TR8 (which redistributes it under TR8's GPL, with attribution); taxify ships none of it and no internet access is required. For European-calibration indicator values see add_eive().
