Joins LEDA Traitbase (Kleyer et al. 2008) plant functional traits to a
taxify() result by looking up accepted_name. LEDA provides species-level
trait data for NW European plant species, covering life form, dispersal,
seed, leaf, and clonality traits.
Arguments
- x
A data.frame returned by
taxify().- verbose
Logical. Default
TRUE.
Value
The same data.frame with additional columns:
- raunkiaer_life_form
Primary Raunkiaer life form classification (phanerophyte, chamaephyte, hemicryptophyte, geophyte, therophyte, helophyte, hydrophyte).
- raunkiaer_variable
1 if species assigned to multiple Raunkiaer forms, 0 otherwise.
- dispersal_type
Primary dispersal type (anemochory, zoochory, hydrochory, autochory, barochory, dysochory).
- terminal_velocity_ms
Seed terminal velocity in m/s (species median).
- seed_mass_mg
Seed mass in mg (species median). Prefixed with
leda_in the .vtr to avoid collision with Diaz traits.- canopy_height_m
Canopy height in meters (species median).
- leaf_mass_mg
Leaf dry mass in mg (species median).
- sla_mm2_mg
Specific leaf area in mm\(^2\)/mg (species median).
- clonal_growth
Capable of clonal growth (1 = yes, 0 = no).
- buoyancy
Seed buoyancy classification.
Details
Source: LEDA Traitbase (Kleyer et al. 2008). Coverage: ~8,000 NW European plant species.
The Raunkiaer life form is a bud-position classification system: phanerophyte = buds >25 cm above soil, chamaephyte = buds near soil surface, hemicryptophyte = buds at soil surface, geophyte (cryptophyte) = buds below soil, therophyte = annual that survives as seed.
