ABSTRACT

The diversity and abundance of dragonflies and damselflies (Odonata) from two different study sites (Durgapur Barrage and Ambuja Wetland) of the Durgapur industrial region of Paschim Bardhaman District of West Bengal, India were investigated from January 2016 to December 2016. Seventeen different physicochemical factors along with Gross Primary Productivity (GPP) and Net Primary Productivity (NPP) were recorded during the present study for a better understanding of the influence of habitat quality on odonate density and diversity. A combination of direct search and opportunistic sighting methods was applied to record 41 different Odonata species. Among the dragonflies, the most diverse family was Libellulidae while among damselflies Coenagrionidae was the most diverse family. Monsoon and post–monsoon seasons were recorded as the months with the highest odonate diversity and density while the winter season was recorded to support the lowest odonate diversity and density. Significant positive correlations were noted between water temperature and odonate diversity. However, negative correlations were noted between water pH, TSS, BOD, COD, and odonate density as well as diversity. The diversity of odonates for the Durgapur Barrage was found to be significantly higher (p< 0.05, ANOVA with Tukey's comparisons) in comparison to the Ambuja Wetland almost throughout the year. The present study clearly indicated a negative influence of habitat alteration and disturbance on odonate density and diversity. These are early warnings of the deterioration of odonates and hence other biota thriving in the present study location.
