“…The relatively low DO values observed in the summer are attributed to the entry of high saline waters in to the mangroves, as well as fluctuations in temperature and salinity, which in turn affect the dissolution of oxygen [40]. This fact is in close agreement with earlier studies done elsewhere [38,41].…”

“…The correlation between the physicochemical parameters and benthic faunal density for the surveyed five mangrove ecosystem showed that the environmental parameters such as salinity, Silt, Clay, TOC, TP and TN were showing strong correlation with the benthic faunal diversity, while other parameters like water temperature, depth, sand and DO had weak correlation with the benthic faunal distribution. Similar variables combination were reported earlier by Sundaray et al in Mahanadi River [54]; Satheeshkumar et al [55] in Pondicherry coast; Sivaraj et al [56] in Nandgoan coastal waters; Sivaraj et al [41] in Vellar-Coleroon estuarine system.…”

“…Canonical Correspondence Analysis (CCA) was done to ascertain the relationship between the physicochemical parameters and benthic faunal density. Similar combinations of environmental variables influencing benthic faunal distribution was reported in Nandgaon coastal waters, Maharashtra, India [56]; Sivaraj et al [41] in Vellar-Coleroon estuarine system. This fact was further confirmed through BIO-ENV, which yielded the combinations of six environmental entities (salinity-silt-clay-TOC-TN-TP) as best match 'defining' the faunal distributions.…”

“…The MDS results also largely followed the trend of dendrogram. Investigation similar to this was carried out by Sivaraj et al [41] who made a comparative study of Vellar-Coleroon estuarine system using macrobenthic communities through cluster analysis. The stress value observed in MDS plot is comparable with the studies [75][76][77].…”

This research article reports an exhaustive account on the mangrove-associated polychaetes. Polychaetes are an important component in marine benthic communities and they play a major ecological role in mangrove ecosystem. This article gives an overview of polychaete diversity associated to five major mangrove forests of east coast of India (Muthupettai, Pichavaram, Coringa, Bhitarkanika and Sundarban). The results of this survey indicated that the physicochemical parameters did not vary much except a few parameters that showed only marginal variations. With regard to the macrobenthic organisms, the polychaetes topped the list. Crustaceans were found to be the next dominant group in the order of abundance and followed by gastropods and bivalves of the total benthic organisms collected. The results of the statistical analysis revealed that the parameters such as salinity, pH, silt, clay, total organic carbon (TOC), total nitrogen (TN) and total phosphate (TP) were manifested as best match in determining benthic fauna distributions followed by TOC, slit, clay and TP. The maximum number of polychaete species was recorded from Sundarban mangroves (68 species) and minimum in Muthupettai mangroves (39 species).

“…In natural environment, high organic wastes resulted in decrease in average dissolved oxygen concentration; moreover, the solubility of dissolved oxygen decreases with increasing temperature and salinity of water [48]. Similar observation with higher value in monsoon and lower in summer seasons was made by Morgan et al [49] and Sigamani et al [50].…”

Studies related to partial pressure of carbon dioxide (pCO 2) concentration linking with polychaete diversity in mangrove ecosystems are limited in time and space. Therefore, the present study was conducted during July 2017-June 2018 on a monthly interval and reported the concentration of pCO 2 coupled with physico-chemical parameters in relation to polychaetes diversity in Pichavaram mangroves ecosystem, southeast coast of India. Totally, 41 species were identified and the most dominant species were Prionospio cirrifera, P. cirrobranchiata, P. sexoculata, Prionospio sp. and Capitella capitata. Among the stations, higher polychaete diversity was found in marine zone compared to other zones. The correlation reflected a significant positive linear relationship between dissolved inorganic carbon (DIC), dissolved organic carbon (DOC), particulate organic carbon (POC) and CO 2 versus pCO 2. The carbon species DIC, DOC, POC and pCO 2 concentration ranged from 1100.1 to 2053.3(µmol/kg), 165.7-1954.0(µmol/kg), 4.5-89.2(µmol/kg) and 184.7-3763.1(µatm), respectively. Further, the statistical analyses revealed that there was a strong correlation among carbon species with distribution of polychaete species in various zones of mangroves and thus indicating pivotal role in occurrence of polychaetes in mangroves.
