I have a query regarding the assigning of super and mixed endemism to plots from the CANAPE analysis. From what I understand super endemism is assigned only if both PE_orig and PE_alt are in the 1% significance range. Else, they are assigned to mixed endemism. So plots assigned to mixed endemism have one of three scenarios: (1) PE_alt is in 5% significance range but not PE_orig (2) PE_orig is in 5% significance range, but not PE_alt (3) both PE_orig and PE_alt are in 5% (but not 1%) significance range. If that is correct, my query is can these 3 scenarios be indicative of different types of mixed endemism, or are they not distinguishable to any specific types? In my dataset I have paleo endemic plots, neoendemic plots, and mixed endemic plots, among which some show scenario (3) and others show scenario (1).

Hello Jack,
Your interpretation of the scenarios is correct, and delving into the mixed category as you suggest would be an interesting idea to pursue.
One can see some of the effects in Fig 3b of the original paper: https://www.nature.com/articles/ncomms5473/figures/3
That figure has axes of PE values, as opposed to significance scores, but the coloured dots represent the significance categories of palaeo, neo and mixed. I would expect the light purple dots to show some differentiation, possibly for those near the edge of the boundaries between mixed and neo/palaeo.
Regards,
Shawn.
