Stopover mass calculator

Description

During stop-overs birds replenish fat mass. Using simplifications from Lindström 1991. The implementation here is simplistic in that muscle mass is not restored as theory and field experiments have shown.

Usage

stopover.mass.calculator(bodyMass, fatMass, taxon, duration)

Arguments

bodyMass

left-over after running function migrate

fatMass

left-over after running function migrate

taxon

(or order) classified into two categories (passerines and non-passerines)

duration

number of hours spent at stop-over site. This must be an integer see example

Value

fat_mass, body_mass

Examples

stopover.mass.calculator(bodyMass = c(2.2, 3.4), fatMass = c(0.34, 0.42),
taxon = c(1,2), duration = 36L)
