| Abstract | This study aims to investigate the diversity, relative abundance, and distribution of land snails in the agricultural areas of Namsuay Subdistrict, Mueang Loei District, Loei Province, during the dry season from November 2022 to February 2023, and the rainy season from June to September 2022. In both seasons, specimen collections were performed in four villages by using a sampling plot size 20 x 20 meters. Six plots were sampled in each village comprising Nanamman Village (NM), Wangkaen Village (WK), Sumpoo Village (SP), and Banpia Village (BP). A total of 5,839 land snail specimens were found, 2,680 (45.89%) in the dry season, and 3,159 (51.10%) in the rainy season. Land snails were classified as belonging to 3 Subclasses 16 genera and 17 species, including Cyclophorus sp., Cyclotus sp.1, Cyclotus sp.2, Dicharax sp., Diplommatina sp., Georissa sp., Pupina bilabiata, Rhiostoma ebenozostera, Achatina fulica, Sarika siamensis, Gulella sp., Gyliotrachela cultura, Hemiplecta distincta, Macrochlamys sp., Prosopeas sp., Sitala sp., and Semperula siamensis. The diversity index (H') is 1.54. The maximum value of H index (Hmax) is 2.83. The evenness index (J') of land snail is 0.54. The exponential of Shannon entropy index (expH') is 4.67. The dominance index (D) is 0.37. Sarika siamensis and Gyliotrachela cultura exhibit the highest relative abundance of 58.67% and 11.59%, respectively. The distribution pattern of land snails in frequency occurrence reveals that Sarika siamensis, Macrochlamys sp., Prosopeas sp., and Sitala sp. show the highest frequency occurrence value of 100%. The similarity coefficient value indicates that Dry-NM and Wet-NM exhibit the highest similarity coefficient, 0.92. |
