surface_area_from_length {TrenchR}

Organism Surface Area from Length

Description

This function estimates surface area (m²) from length (m) by approximating the animal's body as a rotational ellipsoid with half the body length as the semi-major axis.

Usage

surface_area_from_length(l)

Arguments

l

numeric length (m).

Details

Following Samietz et al. (2005) and Lactin and Johnson (1998).

Value

numeric surface area (m²).
