摘要：Present study was conducted to reveals the community structure and diversity of spider species in different habitat types (gardens, crop fields and houses) of Sara n; a part of Indo ¨C Gangetic Plain, India. This area has very rich diversity of flora and fauna due to its climatic conditions, high soil fer-tility and plenty of water availability. The spiders were sa mpled using two semi -quantitative methods and pitfall traps. A total of 1400 individual adult spiders belonging to 50 species, 29 genera and 15 families were recorded during 1stDecember 2013 to 28thFebruary 2014. Spider species of houses were distinctive from other habitats it showed low spider species richness. The dominant spider fami-lies were also differs with habitat types. Araneidae, Pholcidae and Salticidae were the dominant spi-der families in gardens, houses and crop fields respectively. Comparison of beta diversity show ed higher dissimilarity in spider communities of gardens and houses and higher similarity between spi-der communities of crop fields and gardens. We find that spiders are likely to be more abundant and species rich in gardens than in other habitat types. Habitat structural co mponent had great impact on spider species richness and abundance in studied habitats.
