Spider diversity across different habitat types in Bannur village, Dakshina Kannada district, Karnataka, India

Spiders are ecologically important indicators of biodiversity, exhibiting diverse distributions influenced by habitat types. This study investigated spider species richness across five habitats in Bannur Village, Dakshina Kannada District, Karnataka, India, amidst rapid urbanization and habitat transformations. Field surveys conducted from April to June ۲۰۲۰ revealed a total of ۷۳ spider species across ۱۸ families. Notably, the highest species richness was found in native forest (۵۹) followed by home gardens (۴۴), Areca plantation land (۱۵), buildings (۹), and acacia forest (۶). Results also emphasize the habitat-specific adaptation and influence of urbanization on spider diversity. The diverse native forest supported most species while low-diversity acacia forest and regularly checked buildings hosted fewer spider species. This highlights impact of habitat changes on spider diversity. Further long-term research considering variables like climate change, vegetation density, and prey availability would yield a comprehensive understanding of the intricate interplay between environmental factors and spider populations.
