Initial Study of Spatial Distribution of Freshwater Gastropods in UiTM Negeri Sembilan Reserve Forest

Abstract

Freshwater gastropods are a highly diverse and ecologically significant group within the phylum Mollusca. They contribute to nutrient cycling, serve as bioindicators, and support aquatic food webs. Despite their ecological importance, very few comprehensive studies on their presence were done in UiTM Negeri Sembilan Reserve Forest. Thus, this study aims to add more knowledge regarding freshwater gastropods by determining the species’ occurrence and population density in this area. Collection of samples was conducted from March to April 2024 using a quadrat method at three different sites designated as P1, P2, and P3. Observations revealed the presence of only one species, Melanoides tuberculata, with 430 individuals. The density recorded was 277/m² (P1), 168/m² (P2), and 128/m² (P3). This study provides insights into the number of freshwater gastropods from different sites in the area.
