INTERACTION OF AVIAN ASSEMBLAGES WITH THE LOCAL ENVIRONMENT OF SOLID WASTE DISPOSAL AREA: A CASE STUDY FROM PRAMODNAGAR WASTE DUMPING GROUND IN KOLKATA METROPOLITAN CITYTanmoy Dutta, Samir Sardar, Bulganin Mitra, Arunava Mukherjee1 and Banani Mandal
Waste disposal sites are very important area for urban ecosystem due to sharp increment of solid waste generation day by day from municipalities. These sites also provide resources to various bird species though yet their assemblage patterns are not well documented. In the present communication 26 avian species were recorded and spatial assemblage pattern of birds was found among different sub sites (p < 0.05). Wilson-Shmida beta diversity index and Jaccard and Sorenson similarity indices reflects commonness among three sub-sites named tree site, garbage site and locality site in respect of the species composition related to local dispersal of bird between disposal site and human colonies. These disposal sites have usual potentiality to be an important reservoir for various harmful pathogens and parasites.
