Dear all,



I´m using Bray-Curtis index in order to evaluate the difference among different communities in one locality. I used the "classical" approach of compiling the distance matrix, visualising the matrix using NMDS and testing the difference among my communities using permanova.

I would like to relativize the dissimilarity among these communities by comparing the distance I found between them with the distances I found using the same index of distance in other completely different communities in completely different locality. Basically I would like to know if the distance between my current studied communities is smaller than the distances found in other non-related communities.



What will be the appropriate analysis? Would it be correct to use an ANOVA on these distances? The factors will be localities and the variable dissimilarity  among communities?



Thanks a lot in advance!
