Add EIVE ecological indicator values

Joins EIVE 1.0 (Dengler et al. 2023) ecological indicator values to a taxify() result by looking up accepted_name. EIVE provides continuous indicator values for European vascular plants, superseding the original ordinal Ellenberg values.

Usage

add_eive(x, verbose = TRUE)

Arguments

x

A data.frame returned by taxify().

verbose

Logical. Default TRUE.

Value

The same data.frame with additional columns:

eive_light

Light indicator value (continuous).

eive_temperature

Temperature indicator value (continuous).

eive_moisture

Moisture indicator value (continuous).

eive_reaction

Soil reaction (pH) indicator value (continuous).

eive_nutrients

Nutrient indicator value (continuous).

Details

Source: EIVE 1.0 (Dengler et al. 2023, Zenodo, CC BY 4.0). Coverage: ~14.5k European vascular plant species.
