Hello Everyone! I am hoping that you might be willing to entertain a question having to do with developing a diversity index. The question is-is there a way to calculate a sort of 'composite' diversity index that would combine spatial and temporal diversity into a single index value?
See the attached document for an example. Consider a field at time 1 and time 2. There are two scenarios. At time 1, fields for both scenarios have a distribution of A, B, and C elements-these elements are spatially fixed in the positions shown. Notice that at time 1, both scenarios would have the same diversity with regard to A, B, and C. But then, at time 2, notice that scenario 1 remains the same at it was during time 1. But for scenario 2, you have a similar diversity of elements but they are rearranged such that there is something different at each spatial position than there was at time 1. I want to be able to calculate an index that will take this into account. So for instance, if this composite index was calculated for each scenario, scenario 2 would have much greater diversity. Any ideas? Ever seen anything like this? Gratefully yours, Greta
