Limno-ecological studies show that different species have
specific ecological preferences and tolerances to environmental
conditions [1,10,11]. Furthermore, information on ecological preferences
of species based on long-termdata provides useful information about the
changes in aquatic habitats [12,13]. Temporal and/or spatial changes of
environmental variables affect phytoplankton community in an ecosystem;
how to recognize composition and dynamics of phytoplankton is
a serious problem. Multivariate analysis can explain how phytoplankton
composition and dynamics are related to habitat variables. Canonical
Correspondence Analysis (CCA) has been widely used to reduce numbers
of data and determine main environmental variables responsible
