abstract
Present investigation reflects the spider population and diversity according to seasonal variation in the Salbardi forest, Satpura Range, District Amravati, Maharashtra, India. The investigation was carried out for 1 year from June 2012 to May 2013. Sampling was done for three seasons/year viz., monsoon, winter, summer. Spiders were collected in quadrants from different spots by various methods. Different indices were calculated using the Biodiversity pro software version 2. Spider population in different seasons exhibited variation in species abundance and composition. Consecutive survey for three seasons revealed occurrence of 104 species belonging to 18 families. Of these Salticids were predominant (19.23 %) and Aranidae contributed 18.26%. Shannon index, Simpson index, and Margalef Richness index evaluated were 1.06, 0.103 and 8.4 respectively. Spiders belonging to different feeding guild and population were higher during monsoon and winter season. The study suggests influence of seasonal variations on occurrence and diversity of spiders in Salbardi forest.
