Statistical analysis
Two-Way Indicator Species Analysis (TWINSPAN) was used
to classify the entire data set based on the cover estimates of
169 taxa (Hill, 1979). The groups were identified on the basis
of their indicator and dominant species. Canonical Correspondence
Analysis (CCA) is a multivariate analysis technique,whereby a set of biological parameters is related directly to a
set of environmental variables. CCA was carried out to 51 taxa
with relative abundance P10% at the sampling stations. CCA
biplots were drawn with Cano Draw for Windows (Canoco for
Windows version 4.5, Ter Braak, 1987). The environmental
parameters used for CCA analysis were carried out by Abdo
et al. (2012).
