Altogether, 54 sediment samples were collected at 6m intervals along three transects from marsh edge to the back mangroves. The surface sediments were predominantly of sandy-silt nature with high silt (51%) composition followed by sand (36%) and clay (13%) in the order. The analysis revealed a total number of 22 marsh foraminiferal species of which Ammotium salsum (406 ± 477 ind 10cm-3; mean ± 1SD), A. fragile (379 ± 469 ind 10cm-3) and Miliammina fusca (268 ± 273 ind 10cm-3) were abundant in all transects. Species such as Ammonia beccarii (343 ± 526 ind 10cm-3), Bucella frigida (896 ± 362 ind 10cm-3) and Haynesina sp. (224 ± 23 ind 10cm-3), followed by Miliammina oblique (224 ind 10cm-3) and Siphotrochammina sp. (160 ind 10cm-3) are confined only to the intertidal zone indicating their preference to those high salinity (30 psu) regimes. Two planktonic forams notably, Globigerinodes sacculifer and Globigerina sp. are found exclusively in the first few sample collections of transects - 1 and 3, owing to their location close to sea with a regular inundation by rising tides. On the whole, foraminiferal diversity and densities are high at middle and upper marsh areas compared to low marsh or water-edge location. The species-environment relationship (Canonical Correspondence Analysis - CCA) explained up to 63.2% variance (eigenvalue, 0.29) between species and the soil parameters (i.e. elevation, sediment texture – sand, silt and clay, total organic carbon - TOC, pH and salinity) tested. While majority of these variables show positive correlation with the faunal abundance (root-transformed data), pH was found significant (P < 0.05) in controlling their distribution at Kapar.

Dr. Behara Satyanarayana (born on 18 August 1972) obtained his Ph.D. degree from the Marine Biological Laboratory, Andhra University, India (March 2005) for the research work on “Ecobiology and Remote Sensing based study of Coringa mangroves in the Godavari Delta, East coast of India”. He started his career with the aid of European Commission (EC) and the Department of Ocean Development (DOD, India) projects on Coringa for more than 7 years (1994-2002). Later he was nominated for the Senior Scholar Fellowship (2002-2003) under “Indo-China Cultural Exchange Program” by the Govt. of India, and worked for Nanjing University, China. Subsequently, he joined the Chinese Academy of Sciences as a Post-Doctoral Researcher (2004–2006) at the South China Sea Institute of Oceanology. Together with mangrove ecosystem/assessment studies, his professional experience also includes coastal and offshore productivity in the Asian waters using satellite remote sensing. At every step, the works furnished by Dr. Satya continues to recognize through several scientific awards and scholarships with a number of publications in the peer-reviewed journals. He also paid visits to Vrije Universiteit Brussels (Belgium) and University of Ruhuna (Sri Lanka) as a Visiting Scholar to accomplish several research assignments. At present, he is working as Lecturer/Research Fellow at the Institute of Oceanography (INOS), University Malaysia Terengganu (UMT), Malaysia (July 2006 - present).
