Species Composition And Spatial Variation
Of Benthic Diatoms At Intertidal Zone
Under The Influence Of Environmental
Parameters.
Masters thesis, Universiti Sains Malaysia.
Abstract
Benthic diatoms play a significant role in the primary productivity and
sediment dynamics of coastal and estuarine intertidal ecosystems. Thus, this study
aims to determine the spatial distribution of benthic diatoms in intertidal flats from
different environmental gradients. The spatial changes of benthic diatom composition
under the influence of environmental variables in the tidal flats were studied.
Canonical Correspondence Analysis (CCA) was conducted to define the relationships
between environmental variables and diatom communities. Sediment samples were
collected during low tide at six sampling stations four times in November 2013,
February 2014, July 2014 and December 2014 in the coastal area of Tanjung Bungah,
and in August 2014, January 2015, May 2015 and September 2015 in Tanjung Rhu,
Langkawi estuary.
