w_to_rmax {popbayes}

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)

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)
