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).
