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)
