Wetlands are considered as one of the most effective carbon (C) sink among various ecosystems. To substantiate this view, the present investigation was conducted in one of the units of sewage fed East Kolkata wetlands (EKW), a Ramsar site, over a period of 3 years. The result revealed that because of high primary productivity due to abundance of primary producers and other sources of C input primarily through sewage influx, there is net positive balance of C in the system. The rate of C… 
The content, composition, and influencing factors of organic carbon in the sediments of two types of constructed wetlands
Results showed that the content and storage of SOC in SSFCW were significantly higher than those in SFCW, however, the higher proportion of light fraction organic carbon (LFOC) and lower proportion of heavy fractionorganic carbon (HFOC) inSSFCW indicated that SSFCw had less stable organic carbon storage than SFCw.
Status, Potential, Prospects, and Issues of Floodplain Wetland Fisheries in India: Synthesis and Review for Sustainable Management
Abstract India is blessed with vast floodplain wetland resources of 0.5 million ha that are distributed in the Eastern and North Eastern States. They possess varying morphometry, ecological profile,
Integration of pen aquaculture into ecosystem-based enhancement of small-scale fisheries in a macrophyte dominated floodplain wetland of India
The rapid degradation, overexploitation, and encroachment of floodplain wetlands have led to considerable decline in fish diversity and production from these invaluable aquatic resources threatening
The Invasion of Alternanthera philoxeroides Increased Soil Organic Carbon in a River and a Constructed Wetland With Different Mechanisms
Wetlands have been considered as a vital reservoir of global carbon and are vulnerable to plant invasion. However, the influence mechanism of plant invasion on soil organic carbon (SOC) in wetlands
Spatio-temporal change analysis of three floodplain wetlands of eastern India in the context of climatic anomaly for sustainable fisheries management
Floodplain wetlands are ecologically sensitive habitats and considered the most threatened systems due to anthropogenic factors and climatic variability. These wetlands are important fisheries
Commercially and medicinally significant aquatic macrophytes: potential for improving livelihood security of indigenous communities in northern Bihar, India
The dispersed wetlands in the Darbhanga District of northern Bihar, India, provide a diversity of niches supporting substantial floral and faunal richness.  The aquatic macrophytes of a
Impact assessment of barge trafficking on phytoplankton abundance and Chl a concentration, in River Ganga, India
The first such study which depicts the impact of ‘barge movement’ on aquatic food chain linkages in Bhagirathi- Hooghly river is depicted, revealing that phytoplankton biomass (Chlorophyll a) was influenced by ‘ bargemovement’ in the sampling stretches and the impact was assessed by one way ANOVA.
Evaluation of Three Prokaryote Primers for Identification of Prokaryote Community Structure and Their Abode Preference in Three Distinct Wetland Ecosystems
The study results revealed that α-diversity indices and phylogenetic differential abundance patterns did not differ significantly among primers, but they did differ significantly across wetlands, and microbial community composition revealed a distinct pattern for each primer in each wetland.
A history of primatology in India (In memory of Professor Sheo Dan Singh)
The old and the recent primate research in the country are described and research areas for the future are suggested.

Potential of Wetland Macrophytes to Sequester Carbon and Assessment of Seasonal Carbon Input into the East Kolkata Wetland Ecosystem
Wetland is the largest sink of C among entire terrestrial C pool, however, species specific efficiency of wetland macrophytes for sequestering C is not studied well. This study reports seasonal
An appraisal of global wetland area and its organic carbon stock
The present discussion on density distribution of soil organic C in global wetlands could well be instrumental in formulating efficient strategies related to carbon sequestration and reduction of GHG emissions in wetland ecosystems.
Spatio-temporal study of carbon sequestration through piscicultural practice at East Kolkata Wetland.
A significant amount of sequestered carbon was exported from the East Kolkata Wetland ecosystem in the form of fish and this continuous system might increase the carbon sequestration efficiency of the aquatic ecosystem.

Requirements of scientific advancement in understanding of processes regulating carbon (C) balance in terrestrial/semi-aquatic ecosystems, and the roles of the ecosystems in exchange of carbon
Factors influencing carbon, nitrogen, and phosphorus content of fish from a Lake Superior coastal wetland
The narrow fish nutrient ranges (C, 42.8-48.4%; N, 9.6-12.7%; P, 1.91-2.74%) in this study suggest that overall mean values are adequate for quantifying movement of C, N, or P as part of
