This dataset is derived from the WOODIV database (available at: https://www.nature.com/articles/s41597-021-00873-3). It contains the values of four functional traits for 24 Conifer tree species occurring in Portugal, Spain, France, and Italy (Mediterranean part).
This dataset shows the format of the argument species_traits used in
several functions of funbiogeo. Note that species names must be
the first column and must be named species.
Format
A data.frame with 24 rows (species) and the following five columns:
- species
species name corresponding to the columns of
site_species- plant_height
adult plant height (in \(m\))
- seed_mass
seed mass (in \(g\))
- sla
specific leaf area, i.e. the ratio between leaf area and dry mass (in \(m^{2}\cdot kg^{-1}\))
- wood_density
wood density, i.e. stem specific density (in \(kg\cdot dm^{–3}\))
