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

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".

Value

numeric surface area (m2).

Details

All models follow (SA = Ka V2/3) with surface area and volume in meters.

  • Lizards: Norris (1965) :

    \(Ka = 11.0\)

  • Frogs: Tracy (1972) :

    \(Ka = 11.0\)

  • Sphere: Mitchell (1976) :

    \(Ka = 4.83\)
