Abstract
The phytoplankton communities and their environmental factors in the five stations of Tha
Pae canal in Thong Song district, Nakhon Si Thammarat
province were investigated. Monthly collected
during July 2012 to June 2013 were assigned for sampling periods. Phytoplankton samples were
collected using plankton net, mesh sized 16 micrometers. Three divisions of phytoplankton were
found in 28 genera. The Shanon Weaner diversity index wasǰ
-
ǰ bits/individualǰ and Pilou
evenness indexǰ was 0.12-
.ǰ The Multivariate Statistical Package (MVSP) particularly Canonical
correspondence analysis ǰ (CCA) was used to determine the relationship between the water quality
variables and the phytoplankton community. It can be concluded that, dissolved oxygen and total
dissolved solid were the variables most strongly related to the abundance of
Hyalotheca
andǰ
Pandorina
respectively
, while the
cluster analyses showed slightly percentage of similarities.
