- Abstract
Nusa Lembongan and Perancak are two areas located in Bali Province that have mangrove ecosystems that are utilized as ecotourism areas, with different geomorphologies. This study was conducted with the aim to determine the density and spatial distribution of gastropods, as well as their relationship with environmental characteristics using a multivariate analysis approach, namely Correspondence Analysis (CA) and Principal Component Analysis (PCA). Sampling used a purposive sampling method consisting of 3 zones based on distance from the sea, namely the sea, middle and land zones. The results showed that a total of 22 gastropod species were found in Nusa Lembongan where 17 species were found in the marine zone with the most gastropod species Pyrene ocellata (43,48%), while in Perancak 17 gastropod species were found in all zones and the most gastropod species were found in the middle zone, which 13 with the most gastropod species Sphaerasiminea miniate (63,17%). Environmental characteristics such as temperature, pH, ORP, salinity and dissolved oxygen still support the survival of gastropods. In general, 12 mangrove species were found in Nusa Lembongan and Perancak, Rhizophora stylosa, Rhizophora apiculata, Rhizophora mucronata, Rhizophora lamarckii, Bruguiera gymnorrhiza, Ceriops tagal, Avicennia marina, Avicennia alba, Avicennia rumphiana, Avicennia officinalis, Sonneratia alba, and Xylocarpus granatum.
