Hi everybody,

I am tring to get some statistical evidence of differences between my two
fungal mycorrhizal communities (samples from two different Host species)
with ANOSIM test, that's my code:

> dist.ABCD <- vegdist(sqrt.ABCD.1)
> attach(env.table1)
> ABCD.ano <- anosim(dist.ABCD, Host)
> summary(ABCD.ano)

Call:
anosim(dat = dist.ABCD, grouping = Host)
Dissimilarity: bray

ANOSIM statistic R: 0.272
      Significance: 0.001

Based on  999  permutations

Empirical upper confidence limits of R:
   90%    95%  97.5%    99%
0.0407 0.0554 0.0724 0.0952

As I read in a paper, also an R value of 0.27 could be considered
significant. So similar samples are inside the communities and not outside
them, is it roght?
Thank you for you time and patience,


Gian
