The function estimates basal (or resting) metabolic rate (W) as a function of mass (g) and temperature (K). The function is based on empirical data and the metabolic theory of ecology (assumes a 3/4 scaling exponent) (Gillooly et al. 2001) .

Qmetabolism_from_mass_temp(m, T_b, taxon)

Arguments

m

numeric mass (grams).

T_b

numeric body temperature (K).

taxon

character organism type. Options: "bird", "mammal", "reptile", "amphibian", "invertebrate".

Value

numeric basal metabolism (W).
