A function to calculate metabolic rates

All model parameters below were estimated by Barneche & Allen 2018 Ecology Letters doi: 10.1111/ele.12947. These parameters are for the best model (Model 2 in the paper online supplementary material) of fish resting metabolic rates reported in the paper, which also includes trophic level as a covariate.

metabolic_rate(temp, troph, asp, B0, m_max, m, a, growth_g_day, f)

Arguments

temp

Temperature in degrees Celsius

troph

Trophic level (from 1 to 5)

asp

The caudal fin aspect ratio , a proxy for activity level

B0

Constant for resting metabolic rate. If NA, function will calculate an average.

m_max

Maximum biomass fish (in g)

m

Wet weight fish (in g)

a

Resting metabolic rate mass-scaling exponent

growth_g_day

Daily growth in grams of wet weight

f

Activity scope (from 1 to 4)

Value

A dataframe with metabolic rates.
