Species diversity, abundance and habitat association of spiders with relation to their guild composition in different habitats of North Bengal Wild Animals Park (Bengal Safari)
Journal Title: International Journal of Life Science - Year 2018, Vol 6, Issue 4
Abstract
A field study was carried out to determine the spider population and diversity according to seasonal variation in the North Bengal Wild Animals Park, Bengal Safari. Seasonal sampling was conducted. The study was carried out using belt transects, vegetation beating, pitfall traps and leaf litter extraction. Consecutive survey for three seasons revealed occurrence of 38 species belonging to 16 families. Of these Salticids were predominant (31%) and Aranidae contributed 10% of the spider species. Shannon index, Simpson index and Evenness index were evaluated. Spiders belonging to different feeding guild and population were higher during summer season in comparison to other seasons. The study suggests influence of seasonal variations on occurrence and diversity of spiders in the study area.
