Abstract
Numerous micro-invertebrates' biodiversity fluctuates throughout time according to seasonal and temporal patterns year after year depending on various important components including the prevalence of microhabitats, the availability of food sources (preys), the complexity of the flora, etc. The current research looked into the temporal and spatial variation of spider species over a two-year period at four sampling sites within Chincholli Wildlife Sanctuary in Kalaburagi, Karnataka, India. A total of 48 species and 20 families were recorded via alternate methodologies, and the data obtained was then subjected to conventional diversity indexes. Observations indicated that Konchavarm (Site II) and the winter and early winter exhibit the greatest diversity (M1 and M4). Through the use of MANOVA, our study examined how sites and dates affected alpha diversity. The results showed that while dates had no significant impact on alpha diversity, variations in sites impacted. Our findings indicated a substantial positive link between similarity in the spider community and similarity in plant species, distance from one another geographically, and negative correlation between altitudinal separation. The research region had no prior resources in this setting, and these findings shed light on how vegetation complexity supports spiders by creating favourable microclimate and a multiplicity of prey species.
