Figure 2 CCA ordination using all samples during the period from 2009 to 2010.
Note: Axis 1 explained 45.1% and axis 2 explained an additional 74.6% of the variation in the species data. EMZ-M (Estuarine
marine zone - monsoon), EMZ - POM (Estuarine marine zone - post monsoon, EMZ-PRE (Estuarine marine zone - pre monsoon),
EUZ-M (Estuarine upper zone - monsoon), EUZ - POM (Estuarine upper zone - post monsoon, EUZ-PRE (Estuarine upper zone -
pre monsoon).
