TrenchR (version 1.1.1)

surface_area_from_mass: Organism Surface Area from Mass

Description

The function estimates surface area (m²) from mass (g) for one of a variety of taxa.

Usage

surface_area_from_mass(m, taxon)

Value

numeric surface area (m²).

Arguments

m

numeric vector of mass (g).

taxon

character taxonomic classification of organism, current choices: "lizard", "salamander", "frog", "insect".

Details

All models follow (SA = a M^b) with mass in grams and surface area in meters².
