From the resulting dendrogram (Figure 4), it is possible to classify
the results according to stations and also for seasons. Station III
is separated from the others. In the MDS plot (Figure 4), it is found
that all season samples are separated conforming to the dendrogram.
The benthic faunal density (N) (Figure 5A) varied from 84 (station
II, monsoon) to 217 (station I, summer). The Shannon-Wiener index
(H) (Figure 5B) ranges between 4.311(station II, monsoon) and 5.167
(station I, summer). The evenness component (J′) (Figure 5D) varied
from 0.998 (station III, summer) to 0.999 (station I, monsoon). It is low
during the post-monsoon and summer season and gradually increases
during the monsoon seasons. The richness component (D) (Figure
5C) ranged between 16.69 (station II, monsoon) to 32.70 (station I,
summer).
