The demographic potential of a species is limited. The intrinsic rate of
increase rmax is the maximum increase in log population size that a
species can attain in a year. According to Sinclair (2003), it is related
to the body mass of adult females by: \(1.375 \times W^{-0.315}\)
Arguments
- w
a numerical vector. Adult female body mass (in kg).
Value
A numerical vector of rmax values.

Examples
## Set adult female body mass ----
body_masses <- c(55, 127)
## Add species names ----
names(body_masses) <- c("Impala", "Tiang")
## Compute species rmax ----
w_to_rmax(body_masses)
#> Impala Tiang
#> 0.3891244 0.2989541
