Butterfly diversity and abundance with reference to habitat heterogeneity in and around Neora Valley National Park, West Bengal, India
Findings made during this study indicate negative influence of anthropogenic intervention on overall butterfly diversity from the present location and butterflies that showed high occurrences were Indian Tortoise Shell, Yellow Coster and Himalayan Five Ring. Expand
Comparison of avifaunal diversity in and around Neora Valley National Park, West Bengal, India
Anthropogenic intervention has led to conversion of much of the global diversity by means of habitat alterations. The present study was carried out to investigate the importance of habitat qualityExpand
Ecotoxicological Assessment of Tannery Effluent Using Guppy Fish (Poecilia reticulata) as an Experimental Model: A Biomarker Study
Investigation of acute and chronic toxicity of tannery effluent on a fish biosystem by examining oxidative stress enzyme expression in different organs including liver, gills, and muscle suggests elevated activities of stress enzymes in fish upon exposure to environmental pollutants may serve as important biomarkers for oxidative stress.

An observation on the Odonata fauna of the Asansol-Durgapur Industrial Area, Burdwan, West Bengal, India
A suitable geographic location, favourable climatic conditions, heterogeneous habitat types that included ponds, wetlands, riverbeds, grasslands and agricultural lands along with the presence of appropriate vegetation provided a comfortable shelter for Odonata species to flourish in this ecoregion.

Spatio-temporal patterns of urbanization in the Kolkata Urban Agglomeration: A dynamic spatial territory-based approach
Abstract This study analyzes the spatio-temporal patterns of urban growth for the Kolkata Urban Agglomeration (KUA) in eastern India using dynamic spatial territorial extents and compares the resultsExpand
Changing Pattern of Urbanization in West Bengal: An Analysis of 2011 Census of India Data
A proper decentralization of urbanization could be seen both in terms of spatial context and size class distribution in 2011 and could explain the increasing trend of urbanized in the state as a whole in 2011 characterized by the dispersion of dispersed urbanization. Expand
Metallothionein as a Biomarker to Assess the Effects of Pollution on Indian Major Carp Species from Wastewater-Fed Fishponds of East Calcutta Wetlands (a Ramsar Site)
Major significances drawn from the present study were that fish species cultivated in east Calcutta wetland, with its ecosystem being under a potential threat of contamination and stress induced by composite effluents, could lead to adverse physiological conditions. Expand
Changes in Densities of Waterbird Species in Santragachi Lake, India: Potential Effects on Limnochemical Variables
negative correlations of major nutrients (phosphate, nitrate, and silicate) with both GPP and higher avian densities were found and increased areas of open water, which were free of floating vegetation, also likely influenced bird aggregation and the limnochemistry. Expand
Distribution and abundance of three populations of Indian flying fox (Pteropus giganteus) from Purulia district of West Bengal, India
T he present study was carried out to monitor three roost sites of Indian flying fox ( Pteropus giganteus ) populations during the period November 2010 to October 2011 near Purulia, West Bengal,Expand
The Storm Water Flow (SWF) and the Dry Weather Flow (DWF) canals carry composite industrial and municipal effluent (nearly 50,000 m d) from Kolkata city. Wastewater from SWF and DWF canals is usedExpand
