surface_area_from_mass {TrenchR}

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)

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.

• Lizards (Norris 1965; Porter and James 1979; Roughgarden 1981; O'Connor 1999; Fei et al. 2012):
  
  a = 0.000314 \pi
b = 2/3

• Salamanders (Whitford and Hutchison 1967; Riddell et al. 2017):
  
  a = 0.000842
b = 0.694

• Frogs (McClanahan and Baldwin 1969):
  
  a = 0.00099
b = 0.56

• Insects (Lactin and Johnson 1997):
  
  a = 0.0013
b = 0.8

Value

numeric surface area (m²).
