    Algal Resources in the Indian Coastal and Marine Systems with Special Reference to Sundarbans

    By Neera Sen Sarkar, Sanoyaz Sekh

    Abstract: AbstractNaturally endowed with a coastline of about 8,000 Km represented in a wide range of ecosystems like estuaries, mangroves, backwaters, salt marshes, sandy beaches, rocky coasts, coral reefs, and many such variations in ecosystem diversity, India is also predictably blessed with a treasure of marine biotic resources. A conservative estimate of about 80% of all such resources is found in the coastal zones. Such diversity is attributed to the complex …

    Diatom Assemblages in Soil: Implications in Palaeo-Ecological Interpretations

    By Neera Sen Sarkar, Manjushree Mandal, Biswajit Biswas

    Abstract: AbstractDiatoms are microscopic, unicellular, eukaryotic algae belonging to the Class Bacillariophyceae which are abundant in most aquatic habitats and serve as useful proxies for multi-dimensional analysis of ecosystems. They inhabit waters and soils of both saline and freshwater areas. Diatoms as primary producers are vital for life on Earth, serve as significant source of oxygen, have major impact on global carbon cycle and are food source for many organisms at …

    Study of Diatom Flora in Geothermal Springs of Bakreswar, West Bengal, India

    By Neera Sen Sarkar, Manjushree Mandal

    Abstract: AbstractGeothermal springs are mostly formed due to tectonic movements of the earth or volcanic eruptions leading to the release of hot water in the form of artesian wells. The environment is very suitable for the growth of thermophilic Cyanobacteria. Nevertheless, some members ofBacillariophyceae (diatoms) are also found in such geothermal springs, although, very high water temperature and alkaline water is generally not very conducive for diatom growth. The present study …

    Practicing Economy of Nature through Traditional Rice Variety Conservation: A Case Study from West Bengal, India

    By Jimi Banik, Anupam Paul, Sudipta Mukherjee, Saikat Paul, P. D. Ghosh, Neera Sen Sarkar

    Abstract: AbstractTraditional rice varieties (TRVs), continue to be cultivated defying the allurement of high-profits from cultivating high yielding varieties. The reasons why TRVs are still cultivated, withstanding extreme pressures leading to disappearance of many TRVs are interesting, especially for their associated non-market values. This study documents 50 TRVs being cultivated by farmers (n= 488) in three districts of West-Bengal, followed by a criterion-based analysis using UPGMA algorithm applied with Bray-Curtis similarity-index …

    Trend Analysis of Research on Arsenic Pollution in West Bengal, India

    By Sangeeta Dhar, Debal Ray, Neera Sen Sarkar

    Abstract: West Bengal is one of the worst affected states in India in terms of arsenic pollution. Nine out of its nineteen administrative units are severely affected, five moderately affected and a population of over 28 million suffers from the maladies of arsenic pollution. The problem, reported initially in 1978, was clinically detected for the first time in 1983. It gained importance as an issue of concern in the late 80s …
