ABSTRACT

Preliminary studies were performed to understand the seasonal variations of snails (Gastropods), as they play a significant role in the ecosystem by renewing and recycling organic matter. Molluscan animals are bio-indicators useful in bio-monitoring studies. During the present study samples of aquatic invertebrates were collected by the simple net method and terrestrial invertebrates by the simple handpicking method. Changes in the diversity indices of Gastropods were studied for three seasons- Monsoon, Winter and Summer; from June 2021 to May 2022. Diversity indices Shanno Weiner Index (H), Simpson’s Index (1- D), Simpson’s Dominance Index (D), Evenness Index (E), Simpson’s Reciprocal Index (1/D), Gini-Simpson Equitability, Species Richness (R) and Berger Parker Index were calculated for seasonal variations of Gastropods. During the present study total of 11 species were recorded. Those belonged to 8 different families, four were terrestrial and four were aquatic.
