Add spider traits (World Spider Trait Database)

Joins species-level spider morphometric and ecological traits to a taxify() result by looking up accepted_name. Values are aggregated from the World Spider Trait Database (numeric traits by median, categorical traits by mode); access-restricted source records are excluded.

Usage

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

Arguments

x

A data.frame returned by taxify().

cols

Which columns to attach: NULL (default) the curated set, "all" every column the source carries, or a character vector of names. See enrichment_cols.

verbose

Logical. Default TRUE.

Value

The same data.frame with additional columns:

spider_body_length_mm

Body length (mm).

spider_prosoma_length_mm

Cephalothorax (prosoma) length (mm).

spider_prosoma_width_mm

Cephalothorax (prosoma) width (mm).

spider_abdomen_length_mm

Abdomen (opisthosoma) length (mm).

spider_leg1_length_mm

Leg I length (mm).

spider_ballooning

Ballooning (aerial dispersal): yes/no.

spider_web_building

Web building: yes/no.

spider_hunting_guild

Hunting guild.

spider_web_type

Web type.

spider_circadian_activity

Circadian activity (diurnal/nocturnal).

spider_stratum

Vertical stratum (habitat layer).

Details
