w_to_rmax: Compute rmax from adult female body mass
Description
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: \(1.375 \times W^{-0.315}\)
Usage
w_to_rmax(w)
Value
A numerical vector of rmax values.
Arguments
w
a numerical vector. Adult female body mass (in kg).
