Using a k-means analysis⁴² on each of the non-correlated climatic variables, climatic partitioning assigned the populations to four or six groups. QLD, Queensland; MT, mountain; SF, state forest; NSW, New South Wales; N, number of individuals; MAT, mean annual temperature; IT, isothermality; AP, annual precipitation.
