surface_area_from_volume {TrenchR}

Organism Surface Area from Volume

Description

The function estimates surface area (m²) from volume (m³) for a variety of taxa following Mitchell (1976).

Usage

surface_area_from_volume(V, taxon)

Arguments

V

numeric vector of volume (m³). Can be one or more values.

taxon

character taxon of organism, current choices: "lizard", "frog", "sphere".

Details

All models follow (SA = Ka V^2/3) with surface area and volume in meters.

• Lizards: Norris (1965):
  
  Ka = 11.0

• Frogs: Tracy (1972):
  
  Ka = 11.0

• Sphere: Mitchell (1976):
  
  Ka = 4.83

Value

numeric surface area (m²).
