Study of Bird Diversity during Monsoon Season Related to Air Quality at Asansol, West Bengal
Debdyuti Sengupta | Soumendra Nath Talapatra [13]
Abstract: Qualitative and quantitative assessment of bird diversity as during monsoon season and correlated with available air quality parameters of Asansol, West Bengal. For bird diversity assessment, a total500-meter line transects was done randomly weekly twice a day (2hrs. duration in each day) and call count methods in industrial and urban area compared to suburban area for the period of three months (June 2021 ? August 2021). Different biodiversity indices were compared between the sites. Overall air quality data were correlated with the value of bird diversity. In the present findings, qualitative and quantitative assessment indicated that the variety of bird species were observed less numbers (11 types and 118 organisms) in site A1 compared to site A2 (20 types and 202 organisms). Different indices such as Shannon diversity index, Index of Dominance, and Margalef?s species richness index values were higher in site B (2.40, 0.87 and 3.60) when compared to site A (2.00, 0.81 and 2.10) while Berger-Parker Dominance Index value was observed lower in site A2 (0.30) when compared to site A1 (0.36). The values (Mean ? SD) of different air quality parameters (?g/m?) viz. PM2.5, PM10, SO2 and NO2 were 56.66?2.13, 114.32?5.64, 11.22?0.64 and 29.01?1.90, respectively. Different diversity indices were lower in the site A1 may be due to the combinations of air pollutants or PM10 itself when compared to site A2. In future, it is suggested to study avifaunal diversity in dry seasons viz. winter and summer related to the air quality status.
