Hallo ecologists,

I know that this is not the right place where to post my help-request so I
say sorry in advance. My question concern results of biodiversity indices
with diversityresult() tha I used to describe the diversity of two
different, comparable fungal communities.
This is what I got:


Averaged samples Pooled samples
Cultivated Natural Cultivated Natural  ricnhess (S) 3.67
3.42
16 23  Simpson index (D) 0.58
0.49
0.83 0.91

When I use pooled sample I obtain that the natural site is richer than the
cultivated site wheraes when I try to do the average of the diversity
results I have the opposite situation.

My question is, which is the most correct approach to have a real picture
of the diversiy and point the real differences between the two communities?

Thanks a lot in advance,
