3.1.2 Subfamily
At the subfamily level, the patterns were different. For the
Hydrophiinae subfamily, Sal and Tem were the most important variables at
5 arc-minutes for PC, while Nit, Sil and Tem were the most important for
PI. At 10 arc-minutes, Sil and Tem were the most important variables for
PC and Nit and Sil for PI. For the Laticaudinae subfamily, the variables
with highest PC at 5 arc-minutes were Nit, Pho and Sal, while the
variables with highest PI included in addition the Tem. At 10
arc-minutes, Sil and Tem were the most important variables for both PC
and PI. Finally, we did not find differences between each pair of the
same variable when comparing resolutions for both subfamilies in PC and
PI (Table SM3).
