Dear Yong
The simplest approach would be to calculate a phi value for each stream, and
then apply conventional anova.
There is some background on phi here:

There is an example of a simple algorithm to calculate phi from discrete

Dear all,
As you know, before the ANOVA or t-test, we should test the normality of our
data. Sometimes the transformation of our data is necessary, now I have a
question, my data contains both positive and negative( such as 1, 2, -8,
-5). So, which kind of transformation should I take?
Dear list,
I have a problem adding points with different symbols to my
NMDS ordination graph.
I performed a NMDS ordination with this vegan function
(metaMSD) as follow:
metaf - metaMDS(spp, distance = bray, k = 3, trymax =
1000, wascores = T, autotrasform = F, shrink=T, noshare =
1)
