Add Eberswalde long-term carabid monitoring traits and trends

Joins ground-beetle traits and 24-year local population trends to a taxify() result by accepted name.

Usage

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

Arguments

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

Value

The same data.frame with eberswalde_ columns: numeric body_length_mm, humidity_pref, range_centre_lat, abundance_total; categorical wing_morph, feeding_guild, abundance_trend, drought_effect.

Details

Source: Weiss, von Wehrden & Linde (2024), 27 species pitfall-trapped on 13 forest plots near Eberswalde between 1999 and 2022.

body_length_mm, wing_morph and range_centre_lat are carabids.org (Homburg et al. 2014) verbatim, which the deposit's README states and the data confirm: over the 19 species shared with add_chowdhury() every size is exactly equal and every wing class agrees. They are surfaced here because a door should show what its source carries, and they are kept out of add_trait(), where they would double-count one lineage.

What belongs to this deposit alone is the monitoring result: abundance_trend over the 24 years, drought_effect against the 72-month SPEI index, and a feeding_guild refined by the authors' field observations to name the prey. humidity_pref is Sustek's (2004) 1-8 scale, 1 dry to 8 humid.
